I got hooked on wheat grass last summer, which I believe has essentialy the same effects, high chlorophyll intake being one of the key factors for "microgreens".
A quick search on wheatgrass yields:
Vitamins A, B, C, E and K
Calcium, Chlorophyll, Iron, Lecithin, Magnesium, Pantothenic Acid, Phosphorus, Potassium
Amino Acids
Trace Elements
Protein: up to 30%
there's soem good info on the Jambajuice site as well:
And "maximum nutrients" they are. Wheatgrass contains all amino acids, is full of essential fatty acids, vitamins and minerals, vitamins A, C and Bs, is high in iron and vitamin K*. And we mustn’t forget about the enzymes wheatgrass juice delivers. Enzymes are complex protein compounds produced by living cells that speed up biochemical reactions required for proper and normal functioning of every organ system and have also been found to aid digestion!
http://www.jambajuice.com/what/sunshinein.htmlThis on Spirulina from gogreen.net, they also have a good section on wheatgrass and "why eat green micros" in general.
Spirulina provides vitamins, many minerals, essential amino acids, carbohydrates and enzymes. Spirulina is at least 60% vegetable protein, which is predigested by the algae, making it a highly digestible food. It is higher in protein than any other food. Its outstanding nutritional profile also includes the essential fatty acids, GLA fatty acid, lipids, the nucleic acids (RNA and DNA), B complex, vitamin C and E and phytochemicals, such as carotenoids, chlorophyll (blood purifier), and phycocyanin (a blue pigment), which is a protein that is known to inhibit cancer.
