Sea Moss

Seamoss is most commonly consumed in gel form. The raw seaweed is first cleaned and rinsed thoroughly to remove any sand, shells, or debris to make sea moss gel. 

Once cleaned, the sea moss is boiled in water for 10-15 minutes until it dissolves and takes on a thick, gelatinous texture. Some people prefer to boil the sea moss in vegetable or bone broth for added flavor. Milk, nut milk, or coconut water can also be added to the boiled sea moss to make a creamy, enriched gel.

The resulting gel can then be stored in a covered container in the refrigerator for up to 1-2 weeks. Seamoss gel makes an excellent thickener for smoothies, oatmeal, yogurt, ice cream, gravies, desserts, and more. It provides a jelly-like texture with a mildly sweet, salty sea taste. The sea moss gel can simply be scooped and added to any food or beverage.

Dried sea moss can also be used in broths, soups, and stews by simply rehydrating the seaweed in hot water until softened. The dried or powdered herb can be used to make sea moss tea as well.

Some people also like to apply sea moss topically by adding it to baths. Soaking in a sea moss bath can provide minerals and anti-inflammatory benefits when absorbed through the skin.

Finally, sea moss supplements in capsule or tablet form are growing in popularity as an easy way to get a concentrated dose of the seaweed’s nutrients. Taken daily with food, sea moss capsules provide all the benefits of this incredible sea vegetable in a convenient form.

Health Benefits of Sea Moss

Sea moss, also known as Irish moss, is a type of red algae that grows along the rocky coastlines of the Atlantic Ocean. For centuries, civilizations living near the ocean have utilized this sea vegetable as a food source and health remedy. 

Recently, sea moss has exploded in popularity due to its immense concentration of vitamins, minerals, antioxidants, and other nutrients that offer a myriad of health benefits. 

This seaweed contains a wide array of beneficial compounds not found in land vegetables that enhance whole-body function and improve overall health. Let’s explore some of the top evidence-based health benefits of sea moss.

Heart Health

One of the most researched benefits of sea moss is its ability to support a healthy heart and circulatory system. Sea moss contains several nutrients that help regulate cholesterol levels, reduce high blood pressure, and decrease inflammation – all significant risk factors for heart disease.

The soluble fiber in sea moss, or mucilage, has been shown to lower cholesterol levels by binding to cholesterol in the intestines and preventing its absorption into the bloodstream. 

A diet high in soluble fiber can reduce total cholesterol and “bad” LDL cholesterol levels while increasing “good” HDL cholesterol. 

The potassium chloride in sea moss also acts as a vasodilator that relaxes blood vessel walls and lowers blood pressure. High blood pressure strains the cardiovascular system, so maintaining healthy levels is crucial for a healthy heart.

Additionally, the magnesium in sea moss relaxes muscles surrounding the blood vessels, increasing blood flow and oxygen circulation throughout the body. 

The anti-inflammatory compounds in sea moss, like bromine and flavonoids, reduce inflammation throughout the body and within blood vessels. 

Chronic inflammation damages blood vessels over time and sets the stage for atherosclerosis, heart attacks, and strokes. By reducing systemic inflammation, sea moss protects the heart on multiple levels.

According to a 2019 study published in Marine Drugs, the sulfated polysaccharides extracted from sea moss could prevent the hardening and thickening of the arterial walls in test subjects.

The sea moss compounds reversed arterial stiffness, allowing for healthy blood flow. Researchers concluded that sea moss shows immense promise as a therapeutic food for supporting overall cardiovascular health and preventing heart disease.

Weight Loss

Sea moss’s soluble fiber and polysaccharides make it an excellent natural weight-loss aid. Soluble fiber acts as a “bulking” agent in the gut, taking up space and absorbing water to make you feel full for longer. 

This can curb appetite and control cravings, allowing you to reduce daily calorie intake to promote weight loss. Soluble fiber also slows the breakdown and absorption of sugars and carbohydrates, preventing unhealthy spikes in blood sugar that lead to fat storage.

A 2016 study found that soluble fiber significantly reduced both body weight and body mass index (BMI) in overweight and obese participants. 

Researchers noted that increasing soluble fiber intake from foods like sea moss is an effective weight loss strategy with the bonus of improved cardiometabolic health. Other studies confirm that sea vegetable polysaccharides inhibit dietary fats’ absorption and support weight management.

The bountiful iodine in sea moss also regulates thyroid and metabolic function, both of which influence body weight. Optimizing these systems can aid weight loss efforts. The transition metal chromium in sea moss may also curb appetite and balance blood glucose levels. 

Overall, adding sea moss to smoothies, chia puddings, broths, or gel form allows you to harness its soluble fiber, polysaccharides, and nutrients for more effortless weight loss and maintenance.

Thyroid Health

One of the best-known benefits of sea moss is its ability to support thyroid health and prevent hypothyroidism due to its high iodine content. The thyroid gland requires iodine to produce the hormones triiodothyronine (T3) and thyroxine (T4). 

T3 and T4 regulate metabolism, growth, energy levels, body temperature, heart rate, and more. Without ample iodine intake, the thyroid is unable to generate sufficient hormones, leading to hypothyroidism and other issues.

Even mild iodine deficiency can cause thyroid problems over time. Research shows that getting adequate iodine from dietary sources is crucial for maintaining optimal thyroid function and hormonal balance. 

Sea moss is the most abundant source of iodine, far surpassing common iodized salt. Just one tablespoon of dried sea moss contains 4,080 mcg of iodine, meeting your daily iodine needs often.

Consuming sea moss in gel, capsule, or powder form allows you to get the iodine your thyroid needs while avoiding the blood pressure risks of table salt. Iodine also boosts energy levels by facilitating thyroid hormone production. 

Furthermore, sea moss contains selenium and zinc, enhancing thyroid function and aiding hormone synthesis. Sea moss is one of the best natural remedies for comprehensive thyroid support.

Digestive Health

The soluble fiber and unique polysaccharides in sea moss make it a prebiotic powerhouse for digestive system health. Soluble fiber acts as a prebiotic by feeding and supporting the growth of the beneficial Bifidobacterium bacteria in the intestines. Bifidobacterium is involved in nutrient assimilation, vitamin production, and immunity. Feeding these probiotics allows them to thrive.

Soluble fiber also enables regular bowel movements and prevents constipation by absorbing water to soften and add bulk to stool. 

Soft, bulky stools pass smoothly through the intestines, maintaining regularity. Soluble fiber may also help reduce excessive gas and bloating by allowing food to move efficiently through the digestive tract rather than sitting and fermenting.

Furthermore, the polysaccharides in sea moss form a viscous gel-like substance that effectively coats, soothes, and protects the mucus membrane lining of the stomach and intestines. 

This can relieve inflammation, ulcers, and GERD symptoms. For optimal digestion, gut health and regularity, sea moss is an excellent addition to your regimen.

Immune Health

Sea moss is brimming with compounds that boost immune system function, making it a prized immune booster. It contains antimicrobial agents that fight infections from bacteria, fungi, viruses and other pathogens. 

Sea moss is a source of carotenoids, powerful antioxidants that suppress inflammation and remove damaging free radicals throughout the body.

In addition, sea moss has a high concentration of sulfur compounds like DMSO that reduce inflammation and pain internally and when applied topically. 

The zinc in sea moss regulates immune responses and enables rapid wound healing. Iron transports oxygen to cells for energy and supports immune system activity as well.

A lab study found that sea moss extract exhibits anti-viral effects against the herpes simplex virus. Researchers noted that sea moss could aid in the development of antiviral medications to treat these viral infections. 

Regular sea moss intake provides a steady supply of antioxidants, minerals and inflammation-fighting compounds that boost immunity and prevent disease.

Muscle Building and Recovery

The protein, amino acids and minerals in sea moss provide support for muscle growth, strength and recovery. Protein is comprised of amino acids that act as the building blocks of muscle tissue. 

After strenuous exercise, consuming protein helps repair damaged muscle fibers to support gains and strength. Sea moss contains small amounts of complete protein with all essential amino acids necessary for muscle protein synthesis.

The magnesium, potassium, and calcium in sea moss also prevent muscle cramps, spasms and pain that can occur after intense exercise. These minerals balance electrolytes lost through sweat, supporting hydration and muscle function. The anti-inflammatory properties of sea moss can also relieve joint pain and swelling, enabling faster recovery.

These tissue-regenerating effects can help heal strained muscles and injuries suffered during a tough workout. Overall, sea moss makes the ideal post-workout smoothie, shake or gel.
