Bright colours are a big indicator of high antioxidants and that is precisely what Phycocyanin is! Phycocyanin is a strong fighter against free radicals and preliminary research suggests that it may protect cells in the nervous system, liver, heart and kidneys. As oxidative stress increases inflammation, Phycocyanin is known to also have an anti-inflammatory effect in certain conditions. Research relating to other potential health benefits suggest that spirulina may also help to modulate the immune system and reduce cataracts.
