Summary of Customer Ratings & Reviews

Customer Ratings & Reviews

Blue-Green Algae is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from Klammath Lake Blue Green Algae I love Klammath Lake Blue Green Algae and have been taking it for 20 years. I have found that it is a complete food that provides my cells with everything they need. The only remaining sources in the world that are not contaminated are Lake Titicaca in Peru and Klammath Lake in Oregon. The Source Naturals product is as expected, high quality.
