Crispus might find promising pharmaceutical applications for the development of potential novel anti-neurodegenerative drugs for humans.” [2]

Irish Sea Moss is rich in iodine. This mineral is the precursor mineral for the production of T3 and T4 hormones. These hormones are essential for muscle function and coordination, so as brain function. A lack of iodine may cause psychological changes, especially with mood regulations.[3]

Types of Sea Moss in the Market

Irish moss powder and Irish sea moss capsules are Irish sea moss available in the market. These two have gathered popularity because of their concentration and relatively cheaper price. These are also readily available in many online stores. 

They come at different concentrations and prices too which can make us confused. 

A little guide in buying, check these things first before deciding what to buy. 

  1. How product was prepared
  2. Source of the product
  3. Treatment of the product
  4. Manufacturing and packing information

By checking these things, you can minimize the chances of buying synthesis Irish sea moss which can be harmful rather than helpful to the body. 

Irish Moss Powder

Irish moss powder is more used as a household ingredient rather than a medicinal product. It is often used in making sauces, soup, and thickeners. Some make use of Irish Moss Powder to concoct an Irish sea moss gel.

With its growing demand, more and more companies are making their own Irish moss powder and some of them use synthetic means to craft an Irish Moss Powder. 

Others employ harmful means like acid treatment in order to hasten the process of dehydration. By using this method, Irish sea moss actually loses its beneficial properties. Those listed above will be chemically altered into harmful substances that can trigger diseases. 

An example is carrageenan which is widely accepted as edible and beneficial to the body. However, if treated in an acidic environment with a pH below 0, it can become poligeenan which is carcinogenic and toxic to the body. We will talk about this in the latter part of the article.

The source of Irish sea moss should likewise be considered as there is more and more sea moss that is not naturally grown and has high levels of GMOs.

Irish moss powder can retain its full nutrients if processed naturally. Even in its powdered form, Irish moss can still have the nutrients listed about and have the fullest benefits like a regular newly harvested Irish sea moss. 

Irish Sea Moss Capsule

Irish sea moss capsules should be checked according to the guidelines. What’s more? Make it more comprehensive. Because capsuled Irish sea moss is more concentrated than regular dried sea moss, the high probability of having additives is higher. 

However, the Irish sea moss capsule is not 100% unhealthy. Irish sea moss capsules are more for people who need them medically. Since it is more concentrated, it can target the necessary abnormalities more specifically.

Taking the Irish sea moss capsule should be on a prescription basis and not just for personal discrepancy because the outcome and side effects may be severe. 

Other Forms of Sea Moss in the Market

Other than powder and capsule form of sea moss, there are still other forms of sea moss old in the market such as: 


This is the freshest version and also the most recommended form of sea moss to take. However, since sea moss also has a short shelf life, this form is often just available near the source of sea moss.


Dried sea moss is the form in which most sea mosses are sold in the market. However, not all dried sea moss is healthy. One should always be aware of how the sea moss was processed. Always avoid acid-treated sea moss because it contains degraded carrageenan which is harmful to the body. 


Sea moss gel is a topical or food additive. It is usually used as food thickeners or jam base  It is also a natural face mask because of its natural collagen. Sea moss gel has a good absorption rate because of its natural properties. 

What are the Side Effects of Sea Moss?

There are essentially no side effects of sea moss recorded if it is consumed at an appropriate amount. Sea moss is recorded to be generally safe for consumption at normal amounts. 

The side effects of sea moss are from its iodine content. Since Irish sea moss is basically an iodine superfood that is also known to help in thyroid function, eating too much sea moss can lead to iodine toxicity. 

“Excessive amount of Irish sea moss = too much iodine than necessary.”

Too much iodine consumption can make the thyroid gland to function abnormally. It can activate hyperthyroidism or can even lead to carcinoma of the thyroid. 

While these serious diseases can arise due to the accumulation of a disproportionate amount of iodine, other side effects of sea moss may also arise due to the allergic reaction of the body. This is something that can be due to heredity. 

Symptoms include:

  1. Nausea and vomiting
  2. Irritated skin and itchiness
  3. Reddening of skin

If you experience any of these side effects, inform your doctor and stop the use of sea moss immediately. [4

Carrageenan vs Poligeenan vs Degraded Carrageenan

Another hot topic regarding sea moss is the possibility of having carrageenan. 

In fact, sea moss by its nature really has carrageenan but this is not what can cause a carcinogenic build-up in the body.

In definition, carrageenan is defined as “is a common food additive that has been widely used for decades as a gelling, thickening and stabilizing agent.” 

The debate on whether carrageenan is harmful or not has actually been solved and concluded. It states that carrageenan is safe for human consumption. Then, why is there still debate over it? 

The discussion on its safety roots from the confusion in terms. Carrageenan in its original form, which is also found in untreated sea moss is studied to be safe for humans. However, the product of intentional acid-hydrolysis of carrageenan, degraded carrageenan, and poligeenan are the products that are harmful to the human system. 

In a research, it is stated that “[the] confusion was due to the nomenclature used in early studies on CGN, where poligeenan was referred to as “degraded carrageenan” (d-CGN) and “degraded carrageenan” was simply referred to as carrageenan. Although this nomenclature has been corrected, confusion still exists resulting in misinterpretation of data and the subsequent dissemination of incorrect information regarding the safe dietary use of CGN.”  [5]

RIsk of Poligeenan vs Carrageenan

In a meta-analysis, carrageenan post no harm to the body. It also does not affect digestion because of its natural property which prevents it to be absorbed by the GIT. 

While poligeenan is found to generate lesions in the GI tract and even to the extent of being tumorigenic. Since the molecular structure of poligeenan is different from carrageenan, it is absorbed in the GIT and reaches the cell of other organs like the liver. 

Long term exposure from poligeenan can cause:

  1. Lesion or Ulcer in the GIT
  2. Carcinogenic
  3. Possibility of being a tumor promoter
