I don't take your Resveratrol product because it only uses a single source for it: Japanese Knotweed (Polygonum cuspidatum).

I take the Life Extension Optimized Resveratrol product because in addition to the knotweed, it also gets resveratrol from red grapes and wild blueberry, and is also standardized to contain different forms of resveratrol (trans resveratrol, free resveratrol, epsilon-viniferin, trans and cis-polydatin, and pterostilbene).

Your product simply says "Resveratrol, 100 mg, from Polygonum cuspidatum." That doesn't tell me enough.
