Irish Sea Moss Benefits

Numerous studies have looked into the potential health benefits of Irish moss. Before embarking on any new diet, it’s a good idea to consult with your doctor. Because of this, Irish moss has numerous health advantages that might boost your heart and skin, among other things.

1. Good for the Skin 

The omega-3 fatty acids and vitamin A in Irish moss are suitable for the skin. Irish moss also contains collagen-building components. This collagen aids in the growth and repair of the skin, making it appear younger and more immune to the effects of aging.[2]

2. Thyroid

Iodine, which is crucial for thyroid function, is abundant in Irish moss. The thyroid gland regulates metabolic and mental health. A healthy metabolism is supported by Iodine and riboflavin in Irish sea moss.

3. Gut Health

Adding Irish moss to your diet is an excellent way to get a high-quality source of fiber. A diet rich in fiber helps maintain a healthy digestive system and lower cholesterol levels. Good bacteria thrive in an environment rich in Irish moss, which functions as a prebiotic.

4. Aids in Weight Loss

The appetite-suppressing properties of Irish moss may make it an effective weight loss supplement. Appetite suppression and blood sugar control make dieting more manageable. 

5. Heart Health

Irish sea moss is beneficial to the cardiovascular system. You can minimize your risk of cardiovascular disease by taking omega-3s, which are found in it. Heart disease, hypertension, and blood clotting are linked to high cholesterol.

6. Good for the Respiratory System

It is excellent for the lungs since it contains potassium chloride. It helps dissolve phlegm and lowers inflammation; therefore, potassium chloride can reduce congestion. Strengthening one’s immune system could prevent common illnesses like the cold.

7. Rich in Nutrients

It is widely accepted that Irish moss is a good source of essential minerals for human survival. Proteins and vitamins are found in it. In the absence of meat, vegetarians and vegans may suffer from vitamin and mineral deficiencies that moss might help to alleviate.

8. Improves Fertility and Sexual Performance

Irish sea moss contains a significant amount of zinc. It is believed that zinc levels produce higher sex hormones in the body, while iron content increases endurance, which boosts your libido levels.

9. Eases Joint Pains

Studies show that Irish sea moss has fish oil and fatty acids, excellent anti-inflammatory agents. It can help older adults, athletes, and arthritis patients to reduce joint swelling, promote overall mobility and improve flexibility.

10. Skin and Hair

Many social media influencers and celebrities believe that Irish sea moss helps with clear skin and eliminates toxins from the body. It can also help with skin problems like burns, dermatitis, psoriasis, and eczema. However, researchers are still looking for evidence to prove this claim.

Irish Sea Moss Side Effects

Studies have shown that eating up to two tablespoons of Irish sea moss a day has no detrimental effects on the body, but there is no set daily dosage recommendation for this herb. Iodine, an essential mineral for hormone balance, is found in sea moss.

But it is also vital that we note that the known potential risk of consuming Irish sea moss is the risk of consuming metal, as seaweed is known to store and absorb contaminants like metals.

Another downside is the inconsistency in iodine level in the sea moss, depending upon the location. It can result in both hypothyroidism and underactive thyroid level.

A burning or stinging sensation and redness on the skin could be other side effects if applied.

Do consult your doctor before incorporating sea moss into your diet.
