It was discovered that the algae significantly helps to reduce overall cholesterol and minimize LDL – “unhealthy” – cholesterols while maximizing HDL – “healthy” – cholesterols.

This health claim was supported by a study in 2013, where researchers discovered that consuming 1 gram of spirulina per day reduces a person’s total cholesterol after 90 days.
