Spirulina is a powerful tonic and immune-system booster, killing cancer cells and protecting against HIV infections. It increases the production of T-fighter cells, macrophages, B-cells, and the anti-cancer natural killer (NK) cells.
The iron content of spirulina beats raw spinach and whole cereals and is equivalent to red meat. Depending on the variety, it’s 25-50 times richer than raw spinach and twice as rich as the highest iron-rich food — whole cereals.
Spirulina has the highest concentration of protein (by dry weight) found in any food. Depending on the variety, it consists of 65-71% protein whereas soya flour only contains 35% crude protein.
