Overview
Nutrex Hawaii grows this spirulina on its own Kona farm and dries it into a vegan powder sold in a 9.53 ounce container sized for about 90 days of use. It's built for people who already blend greens powders into smoothies or juice.
Farm grown spirulina from a single, traceable source is the differentiator here, since much of the spirulina sold in the US is imported from mixed suppliers. The powder is plant based, vegan and gluten free, which covers most dietary restrictions buyers bring to a superfood powder.
- 9.53 ounce container, 90 day supply
- Farm grown in Hawaii
- Vegan and gluten free
- Non-GMO
Who it's for
Good for people adding a green superfood powder to smoothies or juice for a daily nutrient boost. Not built for anyone who wants capsules or tablets instead of a powder to mix.
Strengths and trade-offs
Drawn from this product's published specifications.
- Grown and dried on a single Hawaiian farm
- Vegan, plant based and gluten free
- 90 day supply in one container
- Requires mixing into a drink, not a capsule
Performance notes
Spirulina powder dissolves into liquid more easily than it presses into tablets, so a powder format suits people who already blend it into a drink rather than swallow it whole. Farm grown production on a single site means more consistent sourcing than spirulina blended from multiple suppliers.
