Spirulina powder is made from fresh spirulina by spray drying, sieving, and sterilization, and its fineness is generally above 80 mesh. The pure color is dark green, and it feels smooth to the touch. It will have a rough feeling if it is not sieved or added with other substances.
1. Protein rich
As a kind of bacteria, it is very rich in protein content, worthy of the name of "single-cell protein." The dried protein accounts for about 60% of the total weight, including the eight essential amino acids of the human body. It is a good protein supplement, especially for vegetarians. It is a relatively comprehensive protein source. Of course, it has no obvious advantages for omnivores and meat eaters.
2. Multivitamins, but no B12
It contains a variety of vitamins, water-soluble, including vitamin C, thiamine, riboflavin, niacin, pantothenic acid, folic acid, and fat-soluble, including vitamin A, E, and K. It should be noted that past tests have found that it is rich in vitamin B12 and can be used as an excellent dietary supplement for vegetarians. However, recent studies have found that it contains a compound with a structure similar to that of vitamin B12. This substance will be mistaken for vitamin B12 by some immunoassay instruments, but these substances cannot play the nutritional role of vitamin B12. Of. It is vitamin B12 free according to more accurate methods.
3. Minerals: iron can be supplemented, but iodine can not be supplemented
It contains iron, calcium, magnesium, zinc, and other trace elements. Among them, iron can reach 28.5mg/100g. Although it is non-heme iron, it is undoubtedly a good source of iron for vegetarians.Then there is the same problem. Many people think that it is seaweed and that eating spirulina can supplement iodine. It has a shallow iodine content, is not listed in the USDA database, and cannot be used as an iodine supplement.
4. Heat
It is not high in calories, and the content of fat and carbohydrates is not high. Appropriate supplementation will generally not delay the weight loss plan. However, because it is generally made into tablets now, it is not satiety. Compete for your stomach space.
In conclusion, spirulina powder is rich in protein and iron. It is a good source of protein and iron for vegetarians (if vegans consider bacteria to be vegetarian), but there are many other options for protein and iron omnivores. Its advantages are not obvious. It is also virtually free of vitamin B12 and iodine.
