Spirulina is a nutritional powerhouse alga that is dried into a bright green powder for consumption. It contains multiple vitamins and minerals, and there is also evidence to support its role in reducing appetite and blood lipid levels. Spirulina was used in a placebo-controlled study to see its effect on appetite and lipid profiling. The findings showed significant reduced appetite when the participants consumed 1 g per day of spirulina in their diets.
