Kelp is a type of seaweed, typically big, within the order Laminariales of the brown algae. Seaweeds are macroscopic, multicellular, marine algae, which normally are benthic, being anchored to the bottom of the ocean or to strong structures. Brown algae consist of a big group of multicellular, mainly marine algae. Brown algae are put in the class Phaeophyceae, but their higher level category is not settled, being otherwise positioned in the kingdoms Plantae, Protista, Chromista, or Chromalveolata, and in the Divisions Heterokontophyta or Phaeophyta.
Kelp does have a plant-like look, having tentacle-like roots from which grows a slim stalk with long, flat, leaf-like blades (Wurges and Frey 2005). The body of a specific organism is known as a thallus rather than as a plant (Kingdom: Plantae). The morphological structure of a kelp thallus is defined by 3 basic structural units (Dayton 1985):.
- The holdfast is a root-like mass that anchors the thallus to the sea flooring, though unlike real roots it is not responsible for absorbing and delivering nutrients to the remainder of the thallus
- The stipe is comparable to a plant stalk, extending vertically from the holdfast and providing a support structure for other morphological features
- The fronds are leaf- or blade-like accessories extending from the stipe, often along its full length, and are the sites of nutrient uptake and photosynthetic activity
In addition, numerous kelp types have pneumatocysts, or gas-filled bladders, normally located at the base of leaves near the stipe. These structures supply the needed buoyancy for kelp to maintain an upright position in the water column.
Development happens at the base of the meristem, where the blades and stipe meet. Growth might be restricted by grazing. Sea urchins, for instance, can decrease entire areas to urchin barrens. The kelp life process involves a diploid sporophyte and haploid gametophyte stage. The haploid stage begins when the fully grown organism releases many spores, which then germinate to become male or female gametophytes. Sexual reproduction then results in the start of the diploid sporophyte stage which will become a fully grown plant.
Kelp grows in underwater “forests” (kelp forests) in clear, shallow oceans. It requires nutrient-rich water below about 20 ° C( 68 ° F ). Kelp is known for its high growth rate: the genus Macrocystis and Nereocystis luetkeana grow as quickly as half a meter a day, ultimately reaching 30 to 80 meters (Thomas 2002). 
Point Loma Kelp Forest
The Point Loma kelp forest, one of the biggest kelp forests in California, is located offshore of the City of San Diego. This urban setting is between the entryways to two big bays, Mission Bay, a recreational park, and the much larger San Diego Bay, a significant naval and business port. The kelp forest is crossed by the outfall from the Point Loma sewage treatment plant; discharge takes place 4.5 miles offshore through several diffusers in 320 foot depths. Within the forest there is intense sport and industrial fishing for sea urchins, spiny lobsters, and fin fishes, and the kelp itself is gathered for the production of alginates. This multi-use resource is also essential to San Diego’s big diving neighborhood. Therefore, the health of this community is of issue to all elements of society.
Like all kelp forests, the Point Loma forest is extremely vibrant (Dayton et al. 1992). Dredging the bays in the early 20 th century transferred sand onto the kelp habitat and restricted both the north and south sides of the kelp forest. In the 1950s the kelp forest was stressed by inadequately dealt with sewage launched within the San Diego Bay and lastly the giant kelp itself practically collapsed in the face of a huge El Nino in the late 1950s. In the early 1950s Scripps Institution of Oceanography began a few of the first collaborated scientific diving research on the planet with various jobs by Connie Limbaugh, Wheeler North, and Jim Stewart amongst numerous. The Scripps research has continued in the kelp forest through today. Given that 1970 the long-term research study has actually focused on long-term transects and research study websites that cover all the habitats within the forest, but many of these sites were selected to continue as carefully as possible to those sites studied by the earlier employees. The research study of these long-term sites is now well into the 4th decade, and due to the fact that the sites were selected to be as close as possible to earlier sites there is even longer continuity. Except for the calcofi program of the California Current, now in its 6th decade, the Point Loma kelp program might be the longest continued marine time-series worldwide.
The present program was started in 1971 (Dayton et al., 1984). In 1983 it was expanded to include population information on kelps and benthic macroinvertebrates at 5 long-term websites. This program was broadened again in the early 1990s to include a lot more websites throughout the kelp forest. Natural disruptions, significantly storms, El Niños, and grazing, triggered major variations in the circulation and abundance of kelps, specifically the huge kelp, Macrocystis pyrifera. Plants in this big forest are affected by gradients in depth, light, temperature level, water movement, nutrition accessibility, and planktonic propagule supply. Storm death is highly depth reliant; the inner edge of the M. Pyrifera forest seems defined by the height of breaking waves (Dayton et al. 1992, Seymour et al. 1989). Kelp recruitment density likewise decreases with depth. In addition to cross coast gradients, there is substantial longshore variability also. Giant kelp plants on the two longshore ends of the forest suffered much higher death than plants in the center of the forest at the same depth throughout two major storm episodes. Alternatively, the end of the forest websites had significantly better kelp survivorship than the main site at the very same depth during the 1983 El Niño summertime; these sites deal with into longshore currents where they might be exposed to water not depleted of nutrients by the rest of the forest (Tegner & & Dayton 1987).
The Point Loma kelp forest continues to face potential threats from natural and anthropogenic impacts. There has been a long-term increase in ocean temperature levels because 1977. The performance of the forest is highly impacted by the low nutrients associated with higher temperature levels. Average giant kelp plant size and efficiency have actually decreased considerably considering that the early 1970s, and will continue to decrease if the warming continues. The strong El Niño of 1997/1998 devastated the Point Loma kelp forest, but was rapidly followed by a La Niñan occasion, which started healing. Intense fish trapping of important sea urchin predators has the prospective to result in more harmful grazing occasions. Non-point source contamination from terrestrial runoff and the bays that bracket Point Loma remain an issue. It is important to understand all sources of variability impacting the kelp neighborhood at Point Loma to separate possible outfall effects from other disturbances. 
In a lot of kelp, the thallus (or body), includes flat or leaf-like structures known as blades. Blades originate from lengthened stem-like structures, the stipes. The holdfast, a root-like structure anchors the kelp to the substrate of the ocean. Gas-filled bladders (pneumatocysts) form at the base of blades of American types, such as Nereocystis lueteana (Mert.& & Post & Rupr. )And keep the kelp blades near to the surface.
Development and recreation
Development happens at the base of the meristem, where the blades and stipe meet. Growth might be limited by grazing pressure, for example sea urchins can lower entire areas to urchin barrens. The kelp life process includes a diploid sporophyte and haploid gametophyte phase. The haploid stage begins when the fully grown organism releases many spores, which then sprout to end up being male or female gametophytes. Sexual reproduction then leads to the beginning of the diploid sporophyte phase which, if lucky, will become a mature plant.
Kelp in history and culture
Throughout the Highland Clearances, lots of Scottish Highlanders were moved off their crofts, and went to industries such as fishing and kelping (producing soda ash from the ashes of kelp). At least up until the 1820s, when there were high falls in the cost of kelp, property managers wanted to develop swimming pools of cheap or virtually free labour, provided by households surviving in brand-new crofting areas. Kelp collection and processing was an extremely lucrative way of using this labour, and proprietors petitioned effectively for legislation developed to stop emigration. But the economic collapse of the kelp industry in northern Scotland led to additional emigration, especially to North America.
Locals of the Falkland Islands are sometimes nicknamed “Kelpers” but this is not used much on their own.

Kelp Nutrition Information
The following nutrition details is offered by the USDA for 1 cup (15g) of dried seaweed.1.
- Calories: 44.7
- Fat: 0.6 g
- Sodium: 86.2 mg
- Carbohydrates: 7.9 g
- Fiber: 0.8 g
- Sugars: 0.5 g
- Protein: 4.8 g
The carbohydrate material of dried kelp is low, with under 8 grams in a full cup. Of this, under 1 gram comes from sugar and fiber.
There is really little fat naturally found in kelp although it may be included during cooking.
Dried kelp has nearly 5 grams of protein per cup.
Vitamins and Minerals
Kelp consists of numerous essential minerals and vitamins, including vitamins K, A, C, and E in addition to folate, vitamin B12, and vitamin B6. It also supplies small amounts of thiamin, riboflavin, niacin, and pantothenic acid.
Iodine is a mineral that’s present in high quantities in kelp. Other minerals include calcium, magnesium, iron, sodium, and phosphorus. 
System of Action
The high iodine material in kelp supports the production of thyroid hormonal agents T3 and T4. If iodine deficiency is severe and prolonged, the thyroid gland enlarges and forms a goiter. This can likewise result in an absence of thyroid hormonal agents (hypothyroidism).
Kelp has potential cancer-fighting properties. Fucoidan from kelp may kill cancer cells and stop their growth.
Nutrients from seaweed carry possible health benefits. Dietary fiber, peptides, lipids, and minerals protect the heart. They may help in reducing markers of heart problem, secure the cells (minimizing oxidative stress), lower swelling in blood vessels, lowers high blood pressure, and decrease blood clotting.
Health Advantages of Kelp
Inducing Labor and Helping With Abortion Procedures
Sticks made of Laminaria (a type of kelp) are used to cause birth and carry out abortions. Different approaches and quantities are used depending on the trimester (inserted into the cervix). The sticks cause the release of prostaglandins, which serve as hormones that assist start womb contractions.
Laminaria sticks can mechanically assist in ending pregnancy from the very first to the late second trimester of pregnancy. In one study (longitudinal), 171 late second-trimester abortions were performed using Laminaria (cervical preparation). Only one had severe issues (no contractions throughout shipment) and 9 required extra precaution.
However, there are better and more secure methods for causing labor or abortion. Depending upon the circumstances, doctors may:
- Ripen the cervix with artificial prostaglandins
- Rupture the amniotic sac
- Provide intravenous Pitocin (artificial oxytocin)
Kelp has a high iodine material (200 to 400 µg). It improved thyroid function in a study of 7 patients with serious motor and intellectual disabilities and hypothyroidism due to iodine deficiency. Patients were provided 1 to 2 grams of powdered kelp daily, and this treatment restored thyroid function, increasing the concentration of iodine in the urine.
In another trial on 36 healthy people, kelp increased the levels of the hormone that stimulates the thyroid gland (TSH).
Nevertheless, extreme quantities might have the opposite effect. In a Japanese medical trial on 13 people, eating 15-30 grams of kelp per day reduced thyroid function, resulting in low thyroid hormone levels.
All in all, the evidence suggests that appropriate kelp doses might enhance iodine deficiency and thyroid function. Make certain to go over with your doctor if it may be useful in your case and how you ought to take it.
Powdered seaweed tablets reduced sugar levels in a research study of 20 subjects with type 2 diabetes (RCT), taken daily for 4 weeks. It reduced fasting and post-meal blood sugar levels and serum lipid (fat) levels. Also, the pills increased HDL levels, which help avoid heart disease connected with diabetes.
In another trial on 65 people, polyphenols drawn out from two various kelp species reduced blood sugar, insulin resistance, and inflammatory markers.
However, an extract with seaweed polyphenols was inefficient at lowering blood sugar levels (both prior to and after meals) in a trial on 26 individuals.
Kelp is a fantastic source of vanadium. Oral vanadium supplements (150 to 300 mg day-to-day) given to 14 type 1 diabetic clients (longitudinal study) for 30 months reduced fasting blood sugar level levels by over 30%. Vanadium also reduced cholesterol levels. It triggered no significant side effects, with the exception of moderate diarrhea at the beginning of the treatment duration.
Vanadium simulated insulin in animal research studies. In one research study with diabetic mice, a vanadium-based substance reduced blood glucose levels and diabetic symptoms (such as thirst, appetite, and weight reduction), with no side effects.
Although restricted, the proof suggests that kelp and its substances might help lower blood glucose and insulin resistance.
A study of Xanthigen, which is a type of kelp, showed decreased body weight, waist circumference, and body and liver fat material in 151 non-diabetic overweight females. It likewise enhanced liver function tests and increased energy use at rest.
Mice fed fats from seaweed had actually increased markers of weight-loss in fat tissue. Fucoxanthin, a pigment from seaweed, produced these impacts.
In a cell study, alginate (a carb present in the walls of algae and seaweed) minimized the activity of a protein in the pancreas that breaks down fats (pancreatic lipase). Lower activity lowers fat breakdown, resulting in less fats being soaked up after a meal.
Again, the results are promising however minimal. Further clinical research is required before concluding for certain that kelp assists with weight-loss.
Blood Clotting and Flow
In a scientific trial on 24 people, dietary fucoidan prevented the formation of blood clots by increasing the production of 2 messengers (hydrogen peroxide and prostacyclins) in the blood vessels.
Fucoidan infusion decreased clotting in bleeding in rats. The rats likewise had less swelling around the location of swelling, moved easier, and had much better memory retention after fucoidan treatment.
Fucoidan supplements avoided blood clotting in mice. The supplements also decreased the activity of embolism stimulators (platelets and fibrin). In another research study, fucoidan injections in mice resulted in boosted cell survival and function in tissues with low blood supply (ischemia).
In tissues with low blood supply, fucoidan decreased cell death proteins (including MAPK, JNK, and caspase-3) and hazardous substances (reactive oxygen species).
Listed below, we will talk about some initial research on kelp’s possible anticancer. It’s mostly in the animal and cell stage and clinical trials have yet to determine if it may work in anticancer treatment.
Do not under any scenarios try to change conventional cancer treatments with kelp, its active compounds, or any other supplements. If you want to use it as an encouraging procedure, talk with your doctor to prevent any unexpected interactions.
A research study of 15 postmenopausal ladies, 10 of whom were breast cancer survivors, took a look at the effects of brown seaweed supplements over a 3-month duration (rotating with placebo). Seaweed decreased an important marker of breast cancer recurrence by half (receptor upar) after 4 weeks.
Fucoidan, an essential component of seaweed, might combat cancer and stop tumor development, based on both cell and animal designs. In addition, seaweed supplements and algae extracts, consisting of the brown seaweed Laminaria, minimized colon, breast, and prostate cancer activity.
Fucoidan injections or fucoidan, when given up food, slowed tumor growth in mice. Fucoidan killed cancer cells by activating the body immune system (by means of natural killer cells).
Fucoidan minimized the development of leukemia cells and killed 2 out of 4 lines checked in a research study. In another study in cells and mice, fucoidan stopped the development and spread of lung cancer cells by blocking development paths (Akt– mtor and NF-kb).
Liver disease C
In a study of 15 clients with persistent liver disease C, fucoidan from brown seaweed was utilized to treat virus-related liver diseases. After 8 to 10 months of treatment, liver disease C infection (HCV) levels in the blood considerably decreased.
Additionally, this research study also examined alanine aminotransferase levels, a protein whose presence correlates to a more serious HCV infection. The blood tests also provide a decline in alanine aminotransferase levels. Despite the positive lab findings, these outcomes did not result in significant clinical improvements.
Animal and Cell Research Study (Absence of Evidence)
No clinical proof supports the use of kelp for any of the conditions listed in this area. Below is a summary of the existing animal and cell-based research study, which must direct further investigational efforts. Nevertheless, the research studies noted must not be interpreted as supportive of any health benefit.
In a rat model, fucoidan (present in kelp) was used to lower swelling triggered by immune cells in the brain. Fucoidan enhanced animal habits, reduced harmful compounds (TNF-alpha), prevented neuron loss, and protected the cells from damage (lowering reactive oxygen types) that can cause neurodegeneration.
In a brain and spine cell study, fucoidan reduced swelling (blocking nitric oxide (NO) and prostaglandin E2 production). Fucoidan also obstructed inflammatory proteins (cytokines IL-1β and TNF-alpha) and the inflammation path (minimizing NF-kβ and p38 MAPK).
Fucoidan minimized all important stars in the inflammatory waterfall in cell studies. In brain immune cells (microglia) fucoidan from brown seaweed showed guarantee for dealing with neurodegenerative diseases brought on by inflammation.
Fucoidan blocked the growth of the herpes simplex virus type 1 (HSV-1) in infected mice. Mice given fucoidan had better survival rates. The treatment improved immune action (natural and adaptive), increasing antibody production.
In a research study (cell), seaweed extracts (including kelp) secured brain cells from death in cell designs of Parkinson’s disease and improved cell survival. It also protected from contaminants, assisting the cells prevent death (via hydrogen peroxide and caspase-3).
Bone Growth and Strength
In a rabbit design, fucoidan assisted produce new vessels, necessary for communication with bones and bone repair. It likewise partly improved bone growth in rabbits with flaws in skull development.
In human stem cells, fucoidan boosted the development of cells that construct bones, called osteoblasts. Fucoidan likewise increased the growth of new vessels, enhancing communication with bones.
In another cell study, fucoidan increased proteins that promote bone and mineral formation (via BMP-2, osteocalcin, and ALP). Fucoidan offered to aged female mice increased bone density and weight recommending that fucoidan may play a role in dealing with age-related bone loss.
High blood pressure
10 protein extracts from a particular sea kelp (wakame) were given to rats with high blood pressure. Of the 10 extracts, 4 experienced reduced high blood pressure after both a single dose and regular use.
In a cell study, 5 organic brown seaweed (kelp) extracts obstructed an important enzyme that may contribute to high blood pressure (Angiotensin-converting Enzyme, ACE). This enzyme is frequently a target for blood pressure-lowering drugs.
Blood Fat Levels
A 1% or 5% fucoidan (from kelp) diet decreased fat in mice that were fed a high-fat diet plan over 12 weeks. Kelp decreased the weight of liver and fat tissue, glucose, and fats (cholesterol and fats) in the blood. It increased the activity of a protein that breaks down fatty acids (lipoprotein lipase), liquifying the plaque in arteries.
The antioxidant residential or commercial properties of fucoidan (from kelp) were confirmed in a cell research study that checked its 2 major parts, sulfate and fucose. Fucoidan revealed antioxidant impacts and has the prospective to be used as a natural antioxidant. 
It’s possible that ancient individuals from Asia followed a “kelp highway” when moving to the Americas. There is a consistently thick line of kelp forests that stretch all the way from Japan, up past Siberia, to Alaska then down the California coastline. Because of the numerous marine life and nutrients in kelp forests, ancient inhabitants might have boated in between islands and benefited from the seaweed as nutrition, along with fish.
In the 19th century, the word “kelp” was used interchangeably with seaweed burned to develop soda ash, likewise known as sodium bicarbonate. The most typical use of this ash is as a water softener.
Kombu is a particular variety of kelp that’s extremely common in Japanese, Chinese and Korean food. The word “kelp” is likewise utilized in Chinese as slang to describe an individual who migrated away from his or her family and after that returned and is still out of work. 
How to prepare with kelp
1. Chinese seaweed salad
Modern Chinese food dish developer and blogger Maggie Zhu states this vegan, seaweed salad is one of her go-to meals during hot, summer season. “It is made with tender and meaty seaweed strips, mixed in a mouthwatering and sour sauce and finished up with garlic-infused hot oil,” she states. “When it’s too hot to make stir-fried veggies, my mommy generally serves this quick cold appetiser with congee and dumplings.” Mouth watering yet?
2. Kelp noodle salad with peanut dressing
If you prefer a peanut sauce over a garlicky one, this dish is right up your ally. Here, kelp is used in place of noodles for a lower-carb option, with shredded carrots and green onions blended right in. The whole shebang is completed with a creamy peanut sauce. Add your go-to protein and this meal works as an entree.
3. Sesame kelp noodles
Kelp tastes just as yummy in warm dishes as it does in cold ones. In this keto-approved recipe, it’s blended with broccoli, carrots, mushrooms, and chicken and topped with a slightly sweet sesame sauce. An included perk: it comes together in less than 30 minutes.
4. Beef seaweed soup
Korean food blogger and recipe developer Holly Elkins enjoys utilizing fresh kelp in her soups because of its soft, velvety texture it takes on when prepared in the broth. Since kelp can be a bit chewy, she suggests cutting it up into small pieces so it’s easier to consume. Make a huge batch of this soup and you can feed the entire fam– or eat it yourself for a couple of days in a row.
5. Seaweed egg drop soup
Another soup to include your kelp to is this seaweed egg drop soup. “I just can’t sing enough applauds to this nourishing soup,” recipe creator and Yang’s Nourishing Kitchen area creator Yang says. “In fact, it has actually been asked for over and over again at our home by my 8-year-old. Even my Canadian-born partner who has an extremely conservative tastebud and would never ever drink any of my bone broth directly, kept going back for seconds.” Her trick? Utilizing shiitake ginger chicken bone broth as a base, which makes whatever added to it teeming with taste. 
Keep your kelp natural
When it concerns consuming kelp, it’s best to do so in its natural type. (If you’re fretted about radiation, know that there has actually been no sign of radioactivity in the United States coastal waters since the summer of 2016.) Kelp supplements can come with some severe health risks, and excessive amounts of iodine can trigger harm to the thyroid.
The FDA advises a dietary intake of 150 micrograms (mcg) of iodine per day. One pound of raw kelp can include as much as 2,500 mcg of iodine, so make certain you read your bundles and consuming kelp in moderation. 
Things to Watch Out For
Heavy metals are an interest in kelp products. Kelp can consist of aluminum, cadmium, arsenic, and lead. Kelp is more likely to include these elements when harvested from areas with industrial advancement. The heavy metals in kelp are normally below harmful levels, but some individuals fret about exposure to them, specifically to arsenic.
Prior to you stress, bear in mind that arsenic is in numerous other foods, including rice and apple juice. Most people will never ever consume sufficient kelp to have an issue with arsenic or other heavy metals. Some individuals decide not to take kelp supplements due to the fact that they might contain more focused quantities of arsenic. 
What are the Most Common Kelp Side Effects?
Natural kelp supplements and items are used by many individuals to improve their health and self-treat a number of medical conditions. These kelp supplements are generally prepared with extracts of Fucus vesiculosus and other related kinds of seaweed and might cause side effects in some people. The most typical adverse effects might be connected to kelp’s iodine content and typically include increased or decreased thyroid hormonal agent levels in the blood in addition to extreme skin lesions.
Undesirable kelp negative effects may differ from person to person, and numerous individuals consume kelp products without experiencing any side effects at all. The presence of iodine can cause stomach irritation, extreme saliva production or an unusual brass-like taste in the mouth. Some kelp items might be polluted with heavy metals that can trigger negative effects associated with these toxins. Individuals who consume kelp contaminated by arsenic can experience nerve issues or kidney damage in some circumstances. Long-term usage may cause a laxative effect in some people from alginic acid, an element of the seaweed.
Some doctor might recommend that pregnant ladies and breastfeeding moms refrain from using kelp products due to their high iodine material and possible heavy metal contamination. Iodine in kelp can communicate with thyroid medications such as levothyroxine and may change the performance of a client’s thyroid in many cases. People who take kelp along with blood-thinning drugs such as warfarin or anti-platelet drugs such as clopidogrel might experience an increased risk of bleeding. People who use laxative products together with kelp may discover an increased laxative result sometimes.
The kelp plant is a common traditional food in Vietnam and some other Asian cultures. Raw kelp might be served as a vegetable or prepared in a salad, although it can be marinaded or prepared in a vegetable soup. Lots of people have actually utilized kelp as a cosmetic and as a conventional medicine for a number of ailments such as coughs, stomachaches and piles. Scientific evidence is generally inconclusive relating to the efficiency of kelp for the majority of medical uses.
In some case, kelp may combat bacterial or fungal infections due to its antibacterial and antifungal properties. Fucoidans are elements of kelp that might have antioxidant results in the body. Fucans, another kelp part, and fucoidans may both have anticoagulant or blood-thinning impacts in some people. In particular instances, kelp might decrease levels of blood glucose in clients with diabetes.
Kelp might likewise have cancer-fighting properties that limit the growth of some cancer cells. Numerous products have high levels of iodine that can enhance goiters in some individuals. A goiter is a bigger thyroid gland that might react to modifications in a person’s thyroid hormonal agent levels and increased iodine consumption. Some weight-loss items consist of kelp, however the effectiveness of this seaweed for reducing weight has actually not typically been studied by scientific researchers. 
Just How Much suffices?
Although kelp has numerous health advantages, its high iodine content can make consuming too much harmful. Talk to your physician prior to taking kelp supplements if you have a thyroid condition, an allergy to iodine, kidney or liver illness. Although the upper limit for iodine is 1,100 micrograms, the FDA set the security standard for iodine material in a kelp supplement to not more than 225 micrograms per day-to-day serving.
Eating kelp as food is safe, but excessive iodine intake from kelp in ascophyllum nodosum supplements can overstimulate your thyroid and trigger swelling of the thyroid gland and increase your threat of thyroid cancer. A very large dosage of iodine can create nausea, fever, weak pulse or a burning feeling in the throat, mouth and stomach.
Interaction With Kelp
Particular medications, drugs and vitamins can connect with extreme kelp intake from supplements. Damaging adverse effects can arise from taking kelp together with:.
- Digoxin (Lanoxin)
Potassium-sparing diuretics such as triamterene (Dyrenium, Maxzide, Dyazide), amiloride and spironolactone (Aldactone).
Thyroid medications such as levothyroxine (Levoxyl, Synthroid), liothyronine (Cytomel), liotrix (Thyrolar), and thyroid (Armour Thyroid) 
A last word on kelp
Kelp is a nutrient-dense edible brown algae. It is a good source of vitamins and minerals, particularly iodine and calcium, and can support bone health, weight upkeep, and, when applied topically, skin look. * Kelp is readily available fresh, dried, and powdered. For a simple way to integrate it into your diet, try adding the powdered kind to water or shakes.
