Nutrex Hawaii Pure Hawaiian Spirulina Review

Nutrex Hawaii Pure Hawaiian Spirulina Tablets are listed as a vegan superfood supplement in 500 mg tablets, sold in a bottle containing 400 count. The page describes the spirulina as Farm Grown in Kona, Hawaii, Non-GMO, Glyphosate Residue Free, 3rd Party Tested, and 60% Protein. The listing states the product is sold by Nutrex Hawaii and shipped by Amazon. The first highlight is pure origin. The page says that in spirulina aquaculture, water quality is everything, and that the brand uses pure, lava-filtered Hawaiian aquifer water rather than industrial run-off or unregulated waters. It asks buyers to always ask the water source. The second highlight is the vegan superfood profile. The page lists 60% plant-based complete protein, naturally occurring amino acids, vitamins A, K1, K2, B12, magnesium, phycocyanin, beta-carotene, iron, GLA, chlorophyll, and zeaxanthin. The suggested use is to take 1 tsp daily in food or beverages. The third highlight is whole-body wellness, where the page describes the product as clinically studied, antioxidant-rich microalgae that supports cellular health and immune function. The fourth highlight compares the product to organic spirulina and greens powders. The page says that half of organic spirulina and greens powders tested contained high lead in a recent 3rd party validated study, with all brands sourcing overseas, and that Hawaiian Spirulina passed all testing, which it presents as proof that purity comes from origin rather than labels. The fifth highlight describes farm growing: the spirulina is sustainably cultivated in Kona, Hawaii for over 40 years, and the page says it is truly U.S.-grown, not just made or packaged in the USA. It is described as Non-GMO, vegan, and with no fillers. Item details list the item form as tablet, dosage form as tablet, flavor as 500mg tablets, special ingredients as chlorophyll and spirulina, container type as bottle, and item weight as 7.04 ounces with 400 count units. Recommended uses are listed as boost energy and immune support. Diet types are gluten free, plant based, and vegan. The age range is adult. The manufacturer part number is 140015. The page also gives a best sellers rank of 8,186 in Health and Household and 6 in Spirulina Herbal Supplements. The legal disclaimer states that the statements have not been evaluated by the Food and Drug Administration and that the product is not intended to diagnose, cure, mitigate, treat, or prevent any disease.

RAL Summary

MembersThe tier and why

, but human evidence is thin and there are 0 reviews. The final check notes: The grade rests on chlorophyll studies, but this product is spirulina, so the 3 g serving is spirulina and chlorophyll is only a minor part of it; spirulina studies were given, and with zero reviews the evidence is still thin.
