JOHANNESBURG - A study by Israeli and Icelandic scientists claims that spirulina may reduce the risk of severe COVID-19 by up to 70 percent.
Spirulina is grown in water and sold in powdered form as a health food supplement to be added to smoothies.
It contains anti-oxidants.
The findings of the study come at a time when South Africa is bracing itself for the fifth wave of COVID-19.
Specialist in complementary medicines, Giulia Criscuolo discussed the outcomes with Gareth Edwards.
