Overall, it's good. No complaints about the effect or quality. But it mixes up a tad gritty, and it's slightly bitter. As reference, the Organic Traditions wheatgrass juice powder is easily more palatable than this blend. I may repurchase as I do like the effects, but it definitely tastes medicinal.
When I dissolved it in water and drank it, it was bitter, sour, and tasteless... When I dissolved it in soy milk, it was fine. There is no description in the ingredients list that you can take natural vitamin C, but it says quercetin in the description, so if it contains quercetin, it is. The expiration date is April 23, so maybe it's stock disposal?
