RationalWiki's 2020 Fundraiser

There is no RationalWiki without you. We are a small non-profit with no staff – we are hundreds of volunteers who document pseudoscience and crankery around the world every day. We will never allow ads because we must remain independent. We cannot rely on big donors with corresponding big agendas. We are not the largest website around, but we believe we play an important role in defending truth and objectivity.

If everyone who saw this today donated $5, we would meet our goal for 2021.

Fighting pseudoscience isn't free.
We are 100% user-supported! Help and donate $5, $20 or whatever you can today with PayPal Logo.png!

Donations so far: $3380Goal: $3500

Spirulina is a kind of cyanobacteria that can live in water with high pH.

What it is[edit]

Spirulina can refer to two species: Arthrospira platensis and A. maxima. It is used as a dietary supplement. It is sold in flake, tablet, and powder form. It's also used as fodder supplement.[1] Spirulina grows best in an environment that has pH of 8.5 or more.
