Algae, particularly species like Spirulina and Chlorella, have been investigated for their potential role in supporting weight loss. The scientific evidence for this use is limited but present. Several small clinical studies have suggested that certain algae supplements may help with weight management by promoting satiety, reducing appetite, or influencing metabolism. For example, Spirulina has a high protein content and is rich in phenolic compounds, which may help enhance feelings of fullness and reduce overall caloric intake. Some studies have observed modest reductions in body weight and body fat percentage among overweight individuals taking algae supplements, possibly due to improved lipid metabolism and glycemic control.

However, the research base is still preliminary, with most studies being small, short-term, and sometimes lacking rigorous controls. There is not yet enough high-quality evidence to support algae as a primary or stand-alone treatment for weight loss. Most experts recommend algae as a supplementary aid within the context of a balanced diet and exercise regimen rather than as a sole intervention. Traditional medicine systems have not widely used algae specifically for weight loss, meaning the rationale for its use is mainly grounded in emerging scientific research rather than long-standing traditional practice. More large-scale, well-controlled studies are needed to confirm efficacy and safety.
