Overview
Nutrex Hawaii markets this as a farm-grown spirulina powder, positioned as a vegan superfood sourced from its own growing operation. The 9.53 ounce bag is sized by the maker for about a 90 day supply, making it geared toward buyers who plan to use spirulina powder regularly rather than occasionally.
The label lists it as gluten free, plant based, and vegan, and the maker markets it for immune support and cellular energy, framed as manufacturer-stated benefits rather than clinical claims. Being farm grown and non-GMO are also called out on the label as sourcing details some shoppers look for in algae-based supplements.
With a 4.6 star rating from nearly 7,000 reviews and about 1,000 units bought in the past month, this is one of the more established and heavily reviewed spirulina powders in the category.

Performance notes
The 9.53 ounce sizing paired with a stated 90 day supply suggests moderate daily serving sizes intended for consistent use. The gluten free, plant based, and vegan labeling should make it compatible with most common dietary restrictions. Any immune support or energy claims on the label reflect the maker's own marketing language rather than independently verified medical claims, and it is worth speaking with a healthcare professional before starting a new supplement routine.
What buyers say
