Today, Spirulina platensis is mostly grown in the United States, India, Thailand, China and Taiwan. Starwest Botanicals is proud to source its Spirulina from the best growers in China, Hawaii and the continental U.S., so you can easily enjoy its healing benefits using both our organic and natural Spirulina Powder. We also manufacture Spirulina Capsules that are made with organic Spirulina platensis and an organic green power blend, which can be taken as a superfood supplement.
