Is spirulina really that healthy?

Spirulina is a blue-green algae that is often consumed as a dietary supplement for its supposed health benefits. It is praised for its rich nutritional profile and is used as a dietary supplement.

Spirulina is rich in several nutrients, including proteins. Spirulina contains a high percentage of protein, often around 60-70% of its dry weight, making it an excellent source of protein, especially for vegetarians and vegans. It is rich in B vitamins and vitamin E. It contains iron, magnesium, potassium and calcium. Spirulina contains phytochemicals such as phycocyanin, which has powerful antioxidant and anti-inflammatory properties.

Spirulina is said to strengthen the immune system, have an anti-inflammatory effect, lower cholesterol and blood pressure and reduce allergies. It is said to contribute to increased energy and endurance. The effect of spirulina was determined based on the effect on certain biomarkers, but clinical studies that prove the effects are lacking.

Spirulina is not without danger. It can become contaminated with toxic substances such as microcystins and heavy metals if grown in uncontrolled environments. People with autoimmune diseases should be careful as spirulina can boost the immune system. There is insufficient evidence about the safety of spirulina during pregnancy and breastfeeding, so it is best to consult a doctor.
