Why supplement?
Marked asPrimarySupporting
Increases plant protein
Arthrospira has almost no cellulose cell wall. The dried powder is high in protein, and phycocyanin carries both a blue pigment and antioxidant peptides. For people who want to increase plant protein with algae, changes in dietary protein sources and digestive comfort are more often noticeable with continued use.
Supports algal micronutrients
When culture conditions are suitable it also carries iron, B vitamins, and carotenoids; phycocyanin gives the dried powder its blue-green color. For people who eat little animal food and want algal micronutrients at the same time, changes in everyday stamina are more often noticeable with continued use.
Support gut microbiota
Spirulina contains polysaccharides and phycocyanin; in vitro and animal work shows it can promote beneficial bacteria and curb some pathogens. Powder is often added to smoothies or meal replacements; people on refined diets with irregular bowel habits who add plant protein often match gaps on this microbiota-support path, alongside micronutrient uses.
