This spirulina tastes good compared to many other brands, and looks to be of high quality. It's high in beta carotene, iron, and vitamin K. Some even claim it has vitamin K2, though I'm not sure if this is verified.
However, the most surprising thing is that it seems to have played a role in helping my liver. I underwent tests which showed elevated liver enzymes (ALT and AST) and a mild case of fatty liver. I took supplements for this and lost a little weight which helped lower them, but they still remained higher than normal range. I later included spirulina (along with other supplements) because there are studies that show it healed fatty liver, and lo and behold the enzymes went to normal. This does not prove there is no fat in the liver, but at the least in my case it seems Spirulina was helpful.
I use this Spirulina daily in smoothis!! And it gives me a boost of energy and I love the taste. This is one of my favourite as it is a clean Spirulina!!! Careful with cheap stuff as its full of heavy metals.
Most Spirulina is grown in tropical waters and the products produced in Asia especially are contaminated by bird droppings and rat hairs. The Earthrise Spirulina is grown in the California desert and is governed by US regulations. I trust it a LOT more than the stuff coming from Asia. The shipment from iHerb came very quickly which was appreciated.
