Spirulina

Spirulina contains 55–70% protein, all B vitamins including B12, iron, vitamin E, beta-carotene, and 18 essential fatty acids. Spirulina's phycocyanin pigment is the only non-animal-derived compound in the article that directly drives mitochondrial biogenesis. Phycocyanin protects nuclear and mitochondrial DNA from oxidative damage and actively participates in DNA repair. Many people report increased energy when supplementing with spirulina regularly. Spirulina's protein content of 55–70% by weight exceeds that of meat, eggs, or legumes on a gram-for-gram basis. Spirulina supplements the diet but does not replace dietary fiber from leafy greens. NASA research concluded that 1 kg of spirulina is nutritionally equivalent to 1,000 kg of fruits and vegetables. Spirulina is a bacterium and blue-green algae, not a plant. Spirulina converts sunlight to chemical energy at roughly 10 times the efficiency of conventional plants. Spirulina is a meaningful longevity food even within a dietary framework rich in animal products. Spirulina has been used as a supportive measure for people exposed to radiation.
