Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Spirulina, a blue-green algae, has a long history of use as a food source, particularly in traditional diets in Africa and Central America. Its use to support "heart weakness"—a traditional term that may refer to general cardiovascular health or heart failure—derives primarily from its reputation as a nutrient-dense superfood. Historically, spirulina has been valued for its high protein content, vitamins, minerals, and antioxidants, which are believed to contribute to overall vitality and wellbeing, including cardiovascular function.

While modern scientific research has begun to explore spirulina’s effects on cardiovascular risk factors (such as cholesterol levels and blood pressure), evidence specifically supporting its use for heart failure or “heart weakness” remains limited and preliminary. A few small clinical studies have shown that spirulina supplementation may help reduce total cholesterol, LDL cholesterol, and blood pressure, potentially offering some cardioprotective benefits. However, these effects are modest, and research is not yet robust enough to support its use as a primary treatment for serious heart conditions.

In summary, spirulina’s use for heart weakness is primarily rooted in traditional and historical practices, supported by limited scientific evidence suggesting possible benefits for heart health. More rigorous clinical trials are needed to determine its efficacy and safety for specific cardiovascular conditions.
