Best Spirulina features Parry Organic Spirulina, blue green algae that provides a safe source of both phycocyanins and phytonutrients. World-wide Spirulina research includes a number of clinical trials that reveal valuable findings in sports nutrition, oxidative stress relief, immune function, and support for the cardiovascular system. Best spirulina offers an ideal source of easily digested phytonutrients due to its lack of a cellulose cell wall, making it one of nature's most powerful green foods.

I liked it

That's quite good spirulina for the price. I don't know if that's because of this supplement, but my blood results were really good last time, even though I don't eat very healthy.

Improves overall feeling

I have been taking 1 per day and I do feel more energetic. I have a thyroid condition so my energy levels are usually on the lower end. This spirulina seems to help with that, however I do like liquid chlorophyll more since it also helped with some other thyroid condition specific symptoms like puffiness and sugar cravings. Spirulina pills are easy to swallow but are a bit dusty so I wouldn't recommend taking when wearing white since your hands and fingers will be covered in green dust :)

Testing its effects on my body. I bought it because in one review it was mentioned that this brand uses organic spirulina from a non- polluted area.
