We offer our products to you with our experience and high formulation skills from our family of three generations of pharmacists. Vitisfera is a pharmacist formulation, but it is 100% herbal and has high purity active ingredients. Resveratrol is supplied by Veri-Te®, a registered and patented trans-Resveratrol brand of Switzerland. Quercetin is obtained from the Sophorae japonica plant with 95% purity. Grape Seed Extract is an extract obtained from natural grape seeds and is 96% pure. Our products do not contain any chemical content and you can use them with peace of mind as they are animal-free. May health be with you with Vitisfera, which draws its power from Resveratrol, grape seed extract and quercetin.
