In the world of fitness anything green never tastes good as expected. However this is the best value for money on the market. Good quality!

Quality stuff

Posted by Sean on December 14, 2017

I’ve tried a lot of spirulina products over the years and this rates high up the list.

Supernaturally fast delivery

Posted by Justin on October 6, 2017

The spirulina is exactly the same as other stuff I’ve bought, so quality checks out. It’s relatively affordable and as the title suggests, the delivery time was insane. I ordered on Friday night, and it was delivered to my doorstep Monday morning in Rural Victoria.

Spirulina goodness

Posted by Sam on August 30, 2017

One of the better tasting Spirulinas I have tried. I mix it with water in a Nutribullet in a few seconds. Goes well with orange juice which tastes a lot better.

Buy capsules

Posted by Alexander on August 7, 2017

The quality is excellent and I feel wholesome and healthy when I incorporate this into my smoothies, however if you’ve never tasted Spirulina before you should be aware that it tastes and smells like fish food designed for the ugly kind of fish that you don’t like because your parents bought you a fish when you actually wanted a dog or a lizard.
Buy the capsules.
