Spirulina has gained popularity in recent years for its incredible nutritional benefits. However, as with many other foods, it has also been surrounded by myths that can generate doubts and confusion. At Blauver, we want to help you know the truth behind these myths and clear up any concerns you may have.

Myth 1: Spirulina 

It is bad for pregnant women

This is a widespread myth, but the reality is that spirulina can be a great supplement for pregnant women, as it is a natural source of protein, iron and antioxidants. Of course, it is important to make sure that the spirulina comes from a reliable source and is free of contaminants. As always, it is recommended to consult with a health professional before incorporating it into your diet during pregnancy.

Myth 2: Spirulina is not suitable for people with thyroid problems

This myth comes from the presence of iodine in seaweed, but what happens if an algae grows outside the sea? It simply does not absorb iodine from the ocean. However, spirulina is not a seaweed, but a cyanobacteria, and at Blauver we grow it in Lleida, the only capital of Catalonia without a sea. Therefore, Blauver spirulina is not only safe for those suffering from hypothyroidism or hyperthyroidism, but can even contribute to hormonal regulation. Of course, the quality and origin of the spirulina are key to guaranteeing its benefits for the thyroid.
