However, while there’s a need for further research in order to confirm all the claims, we can say for sure that Pure Hawaiian Spirulina is one of the most nutritious commercially available spirulina supplements, and it even contains more vitamin A than carrots. It comes both in powder and tablet forms, but the tablet form is more popular among customers.

What should I look for in spirulina powder?

When choosing a brand of spirulina, opt for 100% certified products. The certification means that spirulina hasn’t been exposed to any synthetic pesticides, fertilizers, or GMOs and its manufacturing process complies with strict growing rules.

What is the best form to take spirulina?

Regardless of how and when you take spirulina, you’ll still feel its benefits. Usually, the supplement is sold in the form of powder or tablets, so you can choose the format that works for you.
