What Exactly Is Fresh Spirulina?

So what is fresh frozen spirulina? Fresh spirulina is raw and unprocessed spirulina that has been harvested, pressed, or crushed. The spirulina is made into a paste and frozen to extend its lifespan.

That’s how to make spirulina, and the process is simple and easy. The process is a little complicated when making dried spirulina powder. Here, freshly harvested spirulina is dehydrated, additives added, and then the spirulina is turned into powder.

Manufacturers then pack the powder form while others press it further into tablets.

There are pros to taking fresh spirulina over powder. Fresh spirulina is raw spirulina or live spirulina. It contains enzymes while the dried one is dead lacking extra nutrients.

How Do You Consume Fresh Spirulina?

Consuming fresh spirulina is much easier than you think. You must defrost the spirulina and drink it with water, juice, or smoothies.
