Sea moss is a type of seaweed that can be found in ocean shores. It has been used as a food source for centuries, and is thought to have many health benefits. Sea moss is high in nutrients, including protein, fiber, vitamins, and minerals.
However, there are some concerns about the true nutritional profile of sea moss. In this article, we’ll take a closer look at the nutrient profile of sea moss and see what it actually contains.
What Nutrients Does Sea Moss Have?
Sea moss contains a tiny amount of carbohydrates, zero fats, several minerals, some protein, multiple vitamins, and water content when consumed in gel form.
Sea moss contains minerals like calcium, magnesium, potassium, phosphorus, zinc, selenium, and sulfur as well as protein, and vitamins (B vitamins, vitamin A, K, and C). The water content of sea moss varies greatly depending on how it is prepared.
Does Sea Moss Have Carbs?
Sea moss contains carbs, but only a very small amount. For each 100 gram serving, sea moss contains around 12.3 grams of carbohydrates. This number is relatively small in terms of how much carbs are needed daily. An average person eating 2,000 calories a day needs around 300 grams per day of carbs.
Carbohydrates have received bad press in the past few decades and are often used as a scapegoat for why people are overweight.
The truth is that carbohydrates are necessary macronutrients that provide energy to the body. A person can have too much, but they can also have too little, and this will result in major fatigue and lethargy.
The amount of carbohydrates in sea moss is very low and if you stick with the daily recommended serving of sea moss you will definitely stay under the 300 grams of carbs per day that the Food and Drug Administration recommends.

How Many Carbs in Sea Moss?
Sea moss has an extremely low amount of carbohydrates. A 100 gram serving contains 12.3 grams of carbohydrates. However, the daily recommended serving of sea moss comes to around 4 to 8 grams a day, which is equivalent to one tablespoon of sea moss gel.
One tablespoon of sea moss contains around 4 grams and two tablespoons has around 8 grams. This comes to around 0.49g to 1g of carbs per day. This is an insignificant and almost infinitesimal amount of carbohydrates when you stick with the recommended one or two tablespoons a day of sea moss gel.
What Minerals Does Sea Moss Contain?
For every two tablespoon serving of sea moss, you will receive approximately 7.2 mg of calcium, .89 mg of iron, 14.4 mg of magnesium, 15.7 mg of phosphorus, 6.3 mg of potassium, 6.7 mg of sodium, .195 mg of zinc, .015 mg of copper, .037 mg of manganese, .07 ug of selenium, and more.
Others include aluminum, boron, bromine, cadmium, helium, and iodine, amongst several others.

What Vitamins Does Sea Moss Contain?
In two tablespoons of sea moss, you will receive roughly .3 mg of Vitamin C, .002 mg of thiamin, .047 mg of riboflavin, .058 mg of niacin, .018 mg of pantothenic acid, .007 mg of vitamin B-6, 18.2 ug of folate, 1.29 mg of choline, .6 mg of vitamin A, 7.1 ug of beta carotene, 11.8 IU of vitamin A, .087 mg of vitamin E, and .5 ug of vitamin K.
Other vitamins like vitamin D have been detected but a measureable amount is not indicated in a two tablespoon serving.

What Nutrients does Sea Moss Not Have?
According to data from the United States Department of Agriculture, in a 100g serving of sea moss, there are no measurable amounts detected of vitamins B12, retinol, alpha carotene, lycopene, lutein, cholesterol, fats, folic acid (although it does contain folate) or theobromine.
Sea moss also does not contain any calories, cholesterol, or sugar in a 100g serving.

Final Notes
As we have explored the actual nutrient, vitamin, and mineral content of sea moss, it is important to keep in mind that these are approximate number, but not exact. This is because each batch of sea moss you purchase or find will contain different amount of nutrients.
The nutrient content in sea moss is highly variable due to factors such as the region it grows, whether it was farmed or wildcrafted, and how old the sea moss you purchase is (nutrient content degrades after a year).
Sea moss is a good source of protein, containing all of the essential amino acids that our bodies need. It is also rich in vitamins and minerals, including vitamin C, iron, calcium, magnesium, and potassium. Sea moss is also high in fiber, which is beneficial for digestive health.
We hope you have learned what nutrients, minerals, and vitamins you are-and are not-getting when you consume sea moss.
