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.

Quality Spirulina, A "Superfood"

Size: 360 Count (Pack of 1)

Google Spirulina if you don't know what it is. In short, it's from algae (in this case) that has been shown to provide many health benefits, and studies are underway to validate other claims. One important value: it is one of the few foods that cover essential amino acids. As I said, do your own research. I'm relating what I read and my personal experience. This is, so far, the best spirulina I've found. It is a raw product, vegan, certified organic (by USDA), and proven "bio-active," meaning for me, I absorb it well. It does have an "algae taste" and mild odor (of same). This is difficult to describe, but call it a mild "hay" tone to the flavor. Since it's a pill, it shouldn't bother you. I did notice it the first few weeks, though. IMPORTANT: Not recommended for anyone suffering from phenylketonuria. Ask a medical professional first.

Easy to tolerate, no complaints

Size: 360 Count (Pack of 1)

I JUST STARTED THE 2ND BOTTLE. I take 3 in morning and evening on an empty stomach with 4 or 5 ounces of POM POM juice (pomegranate). I'll do it for a year then evaluate results.
