BIEN-ETE Spirulina: the 6 benefits

3min reading time

Spirulina is not strictly speaking an alga, but a prokaryotic organism, that is, a group of microorganisms or unicellular cyanobacteria, or rather a microalga. Although spirulina adapts to extreme environments, it grows best in mildly alkaline conditions, particularly in freshwater lakes, ponds, and rivers. It also needs abundant sunlight and moderate temperatures. Once harvested, it is freeze-dried or sun-dried. Consuming spirulina, particularly dietary spirulina, is undoubtedly one of the most nutrient-dense foods on the planet, which is why it is considered a superfood and has been consumed for years as a dietary supplement (tablets, capsules) or as spirulina powder.

What are the benefits of spirulina?


It is a good source of plant-based protein

Spirulina is also renowned for its richness in plant-based protein. It contains between 55 and 70% protein, which is highly bioavailable because the proportion of amino acids is optimal, as is their digestibility. However, it cannot be considered a reliable source of vitamin B12 because, although it contains this nutrient in small quantities, vitamin B12 is not as bioavailable as it is in foods of animal origin. Nevertheless, it remains a high-quality microalga and a good substitute for vegetarians.


It has antioxidant properties

Spirulina's antioxidant properties are attributable to phycocyanin (a natural pigment), the substance responsible for spirulina's blue-green color, as well as its carotenoid and zinc content. These antioxidants combat oxidative stress, which can damage the cells in our tissues, and offer numerous benefits, including protecting our bodies against vision degeneration and the weakening of the skin, nails, and hair.


It has a protective effect on the cardiovascular system

By preventing cholesterol oxidation, spirulina helps maintain low levels of "bad" cholesterol (LDL) and supports levels of "good" cholesterol (HDL). Furthermore, studies have shown that when taken in high doses, it provides additional benefits, such as regulating blood pressure. Researchers believe these benefits are due to spirulina's positive impact on the body's production of nitric oxide, which helps blood vessels relax and dilate, allowing blood to circulate more quickly and easily.


It regulates the immune response

Studies have shown that spirulina supplementation may slow the production of cytokines, which play a role in the immune response and inflammatory process. In cases of allergy symptoms in particular, spirulina has proven more effective than placebo in reducing itching, runny nose, nasal congestion, and sneezing.


It could improve the composition of the microbiota

Several studies have shown that spirulina contributes to the growth and multiplication of beneficial intestinal bacteria, and inhibits the proliferation of pathogens such as the fungus Candida Albicans, which is suspected of being involved in numerous digestive and skin disorders and certain autoimmune diseases.

How much spirulina should you take per day?

Spirulina contains many nutrients that are beneficial for health, such as provitamin A, B vitamins, vitamin E, phycocyanin, and essential fatty acids. It should be noted that there is no regulated dosage for spirulina because it is not a medication but rather a superfood that can be taken as part of a course. However, there is, of course, an ideal amount to consume per day. Dosages may differ for athletes because their nutritional needs are different.

However, beware of excessive consumption, which can sometimes cause skin pigmentation (mainly on the palms of the hands). This is due to the high proportion of carotenoids in spirulina, including beta-carotene, hence the orange color of the pigmentation.

There are no contraindications for pregnant women. On the contrary, spirulina's iron content should not be overlooked, and it can be taken with your doctor's approval.
