I have been taking Spirulina for a couple years now, trying to find the best brand that will promote weight loss. Needless to say I haven't found one yet; however, so far this brand seems to be awesome. I take one with lunch, and one with dinner. They smell like fish food (because it literally is fish food lol). The capsules aren't hard to swallow, and they're plant based which is a huge plus. I honestly have nothing bad to say about this thus far. I feel energized and my under eye dark spots are going away, but I honestly can't tell whether that's because I have greatly limited my sugar intake or this product. I will continue to take them and update this review as time goes on.
