A team of scientists from Israel and Iceland have published research showing that an extract of spirulina algae has the potential to reduce the chances of COVID-19 patients developing a serious case of the disease. The research, published in the peer-reviewed journal Marine Biotechnology, found that an extract of photosynthetically manipulated Spirulina is 70% effective in inhibiting the release of the cytokine TNF-a, a small signalling protein used by the immune system.
