This is the best value for money at a very high 300 mg of Trans-Resveratrol per capsule. I think the quality of this brand is excellent. Trans-Resveratrol is very beneficial for health given the thousands of fantastic clinical reports about it from around the world (at PubMed). For me Trans-Resveratrol works slowly but surely to reduce my chronic IBD that had made my life miserable. I have been taking this supplement for 6 months but only about 2 months of this particular brand. I feel completely cured now. I have also been taking other anti-inflammatory supplement but I think Trans-Resveratrol is the key solution. Yes Trans-Resveratrol is a little expensive especially when you want to take several capsules daily. I certainly hope the price will come down as this product becomes more mass market. However what is the price when it can reverse serious chronic diseases that have puzzled and defied the medical profession. Actually one can buy much cheaper wholesale capsules and powder at trading sites but I won't recommend that because those products have not been analysed by an established nutraceutical company in more developed countries like the US. In any case, I can trust the brands carried by iHerb for safety standard. Trustworthiness and goodwill makes for big business!
