Spirulina – the unicellular blue algae is recognized as one of the largest potential sources of proteins and other vital nutrients among plants. It stimulates, strengthens and invigorates the human immune system and turns out to be particularly useful for maintenance of healthy and balanced diet. Moreover, spirulina does not require chemical and physical processing to be digestible as it lacks cellulose cell wall. It is suitable for vegans and vegetarians because it contains twice as much protein as soya.
