Spirulina is purported to have incredible health benefits. It's often recommended for people who are obese as it has huge nutritional value and can replace a meal and help you lose weight. And it can help you stabilize your blood sugar levels.
Spirulina is like seaweed, expect that it grows in fresh water, not sea water.
Spirulina is remarkable in the sense that it is composed of about 65% protein. This protein is perfectly composed, with all the essential amino acids present. This is very unusual for a vegetarian source of food; for example, soybeans are only three percent protein.
Spirulina is also an excellent source of B12, another nutrient usually only found in significant quantities in meat. One teaspoon of Spirulina will provide you with 250% of the recommended daily value of B12.
Spirulina also contains gamma-linolenic acid (GLA), lots of iron , chlorophyll and phycocyanin.
I'm personally not a believer in vitamins or supplements. I think it's much better to change your overall diet toward the healthiest foods rather than focus on various pills and supplements. But spirulina is one item I could personally tout as a real aide to weight loss.
