ypothyroidism occurs when your thyroid can’t produce sufficient hormones. There are many reasons for it, and hypothyroidism is effectively treated today.

If you are looking for a natural and working way to support your thyroid health, rehabilitate after hypothyroidism, or boost your treatment, Irish sea moss might be just a ticket for your well-being journey.

In this article, the True Sea Moss team is looking into using sea moss for the thyroid sternly from a scientific point of view.

The role of the thyroid gland in your body

The thyroid is a small gland that sits in your windpipe and covers it from three sides. It is responsible for breaking proteins and processing vitamins and carbs. Hormones of the thyroid help regulate metabolism and manage other vital hormones of the body (such as dopamine, and adrenaline).

What is hypothyroidism?

Hypothyroidism — or underactive thyroid — occurs when the body is unable to produce enough thyroid hormones. The symptoms of hypothyroidism include:

  • Fatigue and depression
  • Unusual cold sensitivity
  • Uncontrolled weight gain
  • High blood cholesterol
  • Slow heart rate and decreased sweating
  • Irregular periods, anemia, constipation
  • Memory issues, etc.

The symptoms would usually appear gradually, with the continuously decreasing thyroid function.

How do you treat hypothyroidism?

Hypothyroidism can be safely and effectively treated today, usually with the use of supplementation. Changes in lifestyle — for example, cutting down sugar and starting to lead a more active life — are usually recommended by the specialists along with the medications.

If hypothyroidism occurs due to iodine or some other trace mineral deficiency, it can be replenished with supplements. Seaweeds are known to be one of the most abundant natural sources of crucial micronutrients.

The benefits of eating sea moss for the thyroid, for example, lie in its vast iodine, B vitamin, selenium, and magnesium content. It is crucial that you see your healthcare provider before deciding whether to implement Irish moss into your hypothyroid treatment.

Can sea moss help with hypothyroidism?

If you wonder “Is catch-all sea moss good for hypothyroidism?”, we are going to shed light on it. Crowded with some essential for thyroid health micronutrients, this species of Red algae can significantly contribute to your thyroid health and protect it from hypothyroidism development.

The following are the natural remedies for hypothyroidism that can be implemented into your diet with True Sea Moss products:

B vitamins

A deficiency in some of the B vitamins, particularly in B12(1) and B6(2) can lead to an underactive thyroid. Additionally, B vitamins can help your body rehabilitate from the damage caused by hypothyroidism.


Selenium found in the seaweed plays a significant role in the metabolism of the gland’s hormones. Selenium aids in maintaining proper thyroxine levels (T4) and therefore might aid with hypothyroidism.

Fatty acids

Omega fatty acids can help reduce inflammation in the body, which can drastically interfere with thyroid function. Omega fatty acids found in sea moss can also prevent the development of an underactive thyroid(3), and bring many other benefits to the endocrine system.


Like many algae, Irish sea moss is abundant in iodine — a mineral crucial for thyroid well-being. Since iodine is a key component of the gland’s hormones(4), its deficiency can lead to the thyroid's inability to produce enough tetraiodothyronine and triiodothyronine.


Magnesium is involved in numerous bodily processes and enzymatic reactions. For thyroid, is involved in its hormone metabolism and synthesis(5). The seaweed is abundant in magnesium and other essential trace minerals that are beneficial for thyroid and overall health support.

It’s vital that you talk to your healthcare provider and ask whether can you take sea moss with thyroid medication before incorporating it into your diet!
