Keeping It Real

Mixes well with smoothies, cereal, yogurt, and almost anything and leaving no aftertaste. I bought this several times before and will continue to.

Works great for my father in law

Bought this for my father in law and he just loves it. Texture and taste are great and he can feel the difference when he takes it! Arrived super fast! [This review was collected as part of a promotion.]

5 out of 5 stars review

Cost effective but hard on the taste buds!

This is definitely cheaper than tablets but the taste is very unique. I recommend you put some water in your mouth and then pour a scoop into your mouth and swallow. I do not recommend adding it to a shake or other drink since the taste is so strong.
