Does sea moss help burn fat?

Sea moss has gained popularity in recent years as a potential weight loss aid. Some proponents claim that sea moss can help burn fat and promote weight loss. But what does the science say? Here, we’ll take an evidence-based look at whether sea moss lives up to the hype.

What is sea moss?

Sea moss, also known as Irish moss, is a type of red algae that grows along the coastlines of the Atlantic Ocean. For centuries, it has been used as a traditional remedy for various ailments. Today, sea moss is gaining traction as a superfood and weight loss supplement.

Sea moss is rich in nutrients, containing minerals like iodine, magnesium, zinc, bromine, calcium, iron, phosphorus, potassium, and sodium. It also contains vitamins A, E, F, and K. Additionally, sea moss is a source of antioxidants, protein, fiber, and omega-3 fatty acids.

Does sea moss help you lose weight?

There is limited scientific evidence that sea moss directly contributes to weight loss. However, some components of sea moss may support weight loss efforts in indirect ways:

  • Fiber: Sea moss contains soluble fiber, which can help promote feelings of fullness and control appetite. One study found that soluble fiber increased feelings of satiety and reduced food intake at a subsequent meal.
  • Protein: Adding protein to the diet can boost metabolism and reduce appetite. Sea moss contains 5-10% protein.
  • Antioxidants: Antioxidants like carotenoids may help manage obesity by reducing oxidative stress and inflammation. Sea moss contains antioxidants like carotenoids and polyphenols.
  • Iodine: Iodine supports a healthy thyroid, which regulates metabolism. Insufficient iodine can lead to hypothyroidism and weight gain. Sea moss is one of the richest natural sources of iodine.

Potential mechanisms of action

While studies specifically looking at sea moss for weight loss are lacking, some possible mechanisms by which sea moss could aid weight loss efforts include:

  • Increasing feelings of fullness from fiber, supporting appetite control
  • Providing iodine to support thyroid function and metabolism
  • Boosting metabolism through protein content
  • Reducing fat absorption from carotenoids and fucoidan compounds
  • Lowering cholesterol levels from fucoidan
  • Regulating blood sugar response from polysaccharides like alginates

Sea moss weight loss claims

Despite the lack of direct evidence for sea moss and weight loss, some advocates make bold claims about its effectiveness. These include:

  • Promoting fat loss from the body
  • Suppressing appetite and cravings
  • Increasing fat burning and metabolism
  • Reducing fat cell formation and growth
  • Lowering blood sugar and cholesterol levels
  • Detoxifying the body and reducing bloating

Currently, there are no studies examining sea moss’ effects on body composition or weight loss in humans. More research is needed to corroborate these claimed benefits.

Other purported benefits

In addition to weight loss, sea moss is believed to provide other benefits as well. However, more studies are needed to substantiate many of these claims.

Thyroid support

Sea moss is touted for supporting thyroid health due to its high iodine content. Iodine is used by the thyroid gland to produce thyroid hormones. Insufficient iodine can lead to hypothyroidism.

Digestive health

The soluble fiber and polysaccharides in sea moss, like alginates, may help ease constipation by adding bulk to stools and promoting regularity. However, human studies are needed.


Sea moss may stimulate immune function from compounds like polysaccharides and antioxidants. One lab study found it stimulated neutrophil immune cell activity. More research is warranted.

Respiratory health

Traditionally used to soothe sore throats and congestion, limited evidence suggests sea moss may help reduce mucus buildup and inflammation in the airways. Human studies are lacking at this time.

Skin and hair health

Containing antioxidants, vitamins, and minerals, sea moss is claimed to nourish skin and hair. However, direct evidence for this is currently unavailable.

Anti-inflammatory effects

Compounds like fucoidan in sea moss may have anti-inflammatory effects, but human studies are needed to support this. One lab study did find anti-inflammatory effects from sea moss compounds.

Is sea moss safe?

When used occasionally in small amounts, sea moss is likely safe for most people. However, significant safety concerns need to be considered before regular use:

  • Contamination risk: Sea moss can harbor contaminants like heavy metals, which may have adverse health effects. Only source from trusted, reputable suppliers.
  • Iodine content: Excess iodine intake can cause thyroid dysfunction. Those with thyroid issues should exercise caution with high iodine foods.
  • Digestive issues: Due to its mucilaginous texture, sea moss may cause digestive upset, gas, and bloating in some individuals.
  • Blood thinning effects: Fucoidan may increase bleeding risk. Those on blood thinning medications should consult their doctor before use.

It’s best to consult your healthcare provider before taking sea moss if you have any medical conditions or take any medications.

Recommended dosage

There is no official recommended dosage for sea moss. Products are often taken in doses of 1-2 tablespoons (10-20 grams) per day.

It’s best to start with small amounts and increase slowly to assess tolerance. Follow the dosage instructions on any sea moss products.

How to take sea moss

Sea moss can be taken in various forms:

  • Raw sea moss – Soak and blend into smoothies, juices, oats, yogurt, etc.
  • Dried sea moss – Soak and use in recipes or consume as a gel
  • Capsules or powders – Add to water, juice, smoothies, foods, etc.
  • Sea moss gel – Consume directly or use in recipes

Sea moss has a salty, ocean-like flavor. It can be easily added to shakes, smoothies, oatmeal, and even coffee.

Sea moss weight loss results

Very few studies have examined sea moss and weight loss directly. Currently, evidence of significant weight loss from sea moss is anecdotal:

  • In one small study in rats, sea moss extract reduced body weight gain by over 30% compared to control groups.
  • Some people report losing up to 10 pounds of body fat when taking sea moss. However, other factors like diet and exercise likely contribute.
  • Youtube videos and testimonials detail individuals’ experiences losing weight with sea moss. But these are unreliable forms of evidence.

Right now, there is insufficient evidence that sea moss induces significant weight loss in humans. More controlled studies on sea moss and body composition are needed.

Sea moss weight loss before and after

There are many anecdotal stories and before/after pictures of people attributing weight loss to sea moss. However, these lack scientific validity. Without controlled diets and other variables accounted for, it’s impossible to know if sea moss is directly causing weight loss in these uncontrolled claims.

Sea moss weight loss reviews

Reviews of sea moss for weight loss are generally positive. Many people claim noticeable weight loss and appetite suppression from sea moss. However, reviews are also mixed. Some report no change in weight from sea moss alone without diet and lifestyle changes. Critical reviewers argue there is lack of evidence for substantial weight loss.

Ultimately, uncontrolled customer reviews are weak evidence. Without controlled clinical trials on sea moss and weight, reviews showing weight loss could simply be due to changes in diet, exercise, or other factors.

Sea moss weight loss recipes

Here are some popular recipes using sea moss gel for weight loss:

Sea Moss Smoothie

Blend sea moss gel, banana, strawberries, coconut milk, and ice. Sweeten if desired with honey or stevia.

Sea Moss Overnight Oats

Combine oats, chia seeds, sea moss gel, almond milk, and cinnamon. Refrigerate overnight.

Sea Moss Coffee

Stir sea moss gel into your regular coffee along with coconut oil or ghee.

Sea Moss Gel

Soak raw sea moss to extract gel. Take daily alone or add to foods and drinks.

The bottom line

At this time, there is limited clinical evidence directly linking sea moss to weight loss. While sea moss provides nutrients that may support weight loss through mechanisms like appetite regulation and thyroid support, human studies are lacking.

Anecdotal reports and personal testimonies suggesting sea moss contributes to weight loss are unreliable. Solid data from controlled trials is needed.

Sea moss may help boost nutrient intake to promote wellness and support a healthy lifestyle conducive to weight loss. However, it’s unlikely sea moss will induce significant weight loss on its own without diet and lifestyle changes.

As with any supplement, it’s best to speak to your healthcare provider before taking sea moss, especially if you have any medical conditions.


While sea moss may provide indirect benefits for weight loss through its nutrition content, there is currently a lack of robust evidence demonstrating sea moss can directly produce substantial weight loss. More rigorous human clinical trials are needed to determine if sea moss has meaningful effects on body weight and composition.

For now, maintaining a calorie deficit through diet and exercise remains the most proven approach for weight loss. Sea moss may serve as a beneficial complement to a healthy lifestyle, but likely does not cause significant weight loss on its own.
