Nutrient profile

Sea moss has an exceptionally high content of micro and macronutrients. It's estimated that it contains 92 out of the 102 minerals and vitamins our bodies require. Here's a breakdown of its key nutrients:

  • Minerals: Sea moss is rich in essential minerals, including but not limited to iodine, iron, calcium, magnesium, phosphorus, zinc, and selenium. 
  • Vitamins: It's a good source of vitamins, particularly B vitamins such as folate (B9) and cobalamin (B12), which are essential for brain health and energy levels. It also has good amounts of Vitamin C and Vitamin A. 
  • Fiber: Sea moss contains algin, a fiber that acts as a prebiotic and improves gut health.
  • Fatty acids: It also contains a variety of omega-3 and omega-6 fatty acids that are considered "good" fats and are essential for heart health.

The exact nutrient content of sea moss can vary depending on the water it grows in and how it's prepared.

Health benefits

The list of sea moss’s health benefits is quite extensive as this seaweed has been traditionally used to prevent or treat a vast range of chronic conditions, including diabetes, low immunity, infertility, respiratory conditions, kidney disease, cholesterol, arthritis, allergies, obesity, digestive disorders, and even mental health issues.
But if we should list only a few, here’s what sea moss is best known for:

  • Thyroid support: Sea moss is rich in iodine, a rare mineral that the thyroid gland needs to produce the hormones that regulate metabolism, promote growth and development, and influence heart rate and body temperature.
  • Dietary balance: Containing such a great variety of vitamins and minerals, sea moss helps fill nutritional gaps when consumed daily. Ultimately, it improves overall health and helps prevent numerous chronic conditions caused by dietary deficiencies.
  • Digestive health: Sea moss is rich in algin fibers and improves digestion. Algin is a mild natural laxative that acts as a prebiotic to improve overall gut health.
  • Weight loss: It's rich in dietary fiber, helps regulate the appetite, boosts metabolism, and burns fat, making it an excellent weight-loss supplement.
  • Skin and hair: When applied topically, sea moss gel profoundly nourishes and soothes the skin, addressing issues like dryness, flaking, and even some skin conditions like eczema, psoriasis, and acne. Additionally, it's considered one of the best plant-based sources of collagen. 
  • Immune support: Sea moss's high content of antioxidants and vitamins can help boost the immune system, allowing the body to fight off infections and diseases. It's also a great detox ingredient that helps the body flush out toxins and combat free radicals.

Spirulina Overview

On the other hand, spirulina, also called blue-green algae, is a microalga that grows in both fresh and salt water. Technically, it’s not a plant but a cyanobacterium (single-celled microbe).
Like sea moss, it is considered a superfood due to its exceptional nutrient content. It is one of the oldest forms of life on Earth and was first used by the Aztecs as an energy booster.

Nutrient profile

Like sea moss, spirulina is known for being a nutrient-dense food. Here are some of its key nutrients:

  • Protein: Spirulina is a complete protein, meaning it contains all the essential amino acids you need from your diet. Its protein content per gram is close to eggs and higher than most vegetables and grains.
  • Vitamins: It's rich in B vitamins, particularly thiamin (B1), riboflavin (B2), and niacin (B3), but also contains a good amount of Vitamin E and small amounts of Vitamin A and Vitamin K. 
  • Minerals: Spirulina is a good source of iron. It also contains notable amounts of copper, magnesium, and manganese.
  • Fatty Acids: Although it's not a top source of omega-3s, spirulina does contain some gamma-linolenic acid (GLA), a type of omega-6 fatty acid with anti-inflammatory properties.

As with sea moss, the nutrient profile of spirulina can also vary based on environmental factors and how it's harvested and processed.

Health benefits

Like sea moss, the list of spirulina's health benefits is also long. However, spirulina is mostly used for the following purposes:

  • Plant-based protein: Spirulina is a high-quality source of protein and can be highly beneficial for those following a plant-based diet.
  • Antioxidant and anti-inflammatory properties: Like sea moss, spirulina is loaded with antioxidants, including phycocyanin, which can protect against oxidative damage. Its anti-inflammatory effects also help reduce inflammation in the body.
  • Blood sugar control and cholesterol: Some studies suggest that spirulina helps manage blood sugar levels, potentially offering support for those with diabetes. It is also believed to benefit heart health by reducing "bad" LDL cholesterol and potentially increasing "good" HDL cholesterol. 
  • Energy and exercise performance: Thanks to its high protein content and wide range of vitamins and minerals, spirulina is known for increasing energy levels and improving physical performance, especially in athletes.


Spirulina is primarily consumed in a dried powder form. This can be mixed into smoothies, juices, or sprinkled over your meals.
Like sea moss, it’s also available in tablets to be taken as a dietary supplement.
Spirulina can be applied on the skin too, but unlike sea moss gel that is ready for topical use, you must mix spirulina powder with water or oil ingredients first.

Sea Moss Vs. Spirulina: Which is Better?

Whether sea moss or spirulina is better depends on your health goals, nutritional needs, and dietary preferences. Each superfood has a unique nutritional profile and offers distinct health benefits.
Sea moss contains a greater variety of minerals and vitamins than spirulina, making it more "complete" as a health supplement. It also has more iodine than spirulina, which is especially recommended for thyroid disorders. Another significant difference is the fiber content, much higher in sea moss than in spirulina, making it a better choice for people with digestive health issues. 
On the other hand, spirulina shines in terms of its high protein content. It contains 30 times more protein than sea moss, including all essential amino acids, making it an excellent supplement for those needing more protein, such as vegans or vegetarians. Spirulina also has a higher iron content.
It's also worth considering the taste and texture of these two supplements, as well as their respective methods of consumption. For example, if you’d like to care for your skin or hair, sea moss is more appropriate as its gel can be used as a face mask or a hair soother.
It’s important to understand that one is not inherently better than the other; they simply offer different benefits.
