The book is so not fun to read
Format: Paperback
Nothing with the seller, it's just the book that I don't like. Black and white, full of info and boring

Easy, quick protein boost, little taste, quality product -- very happy with it. This is my third bottle.

It HAS helped with my energy levels!
Size: 360 Count (Pack of 1)
Might be better to take the powder, because I end up taking 12 of these tablets at a time to get the 6 grams of spirulina I want to take. But because they are simpler and cleaner than a powder would be, I may just stick with this! I have noticed my body has more stable energy on the days I remember to take this. And I can take them on an empty stomach which tells me they don’t have toxins or bad preservatives.
