Procyanidins (antioxidants) exist in many plants and can improve immunity to some extent. Usually, ordinary consumers buy "grape seed extract" (OPC), so it is recommended to buy this health care product containing anthocyanins. At present, allergic reactions and sneezing symptoms are easy to occur in spring and autumn, so I have been taking capsules containing grape seed extract here. As for this kind of goods, you'd better buy them in a drugstore. Pay attention to the content and composition of anthocyanin, because the difference of composition and content will affect the price and taking effect.

Regarding brands, I have photographed many brands, but in order to avoid advertising suspicion, I don't provide personal advice. According to my personal income level, the usual dosage of 65438+ me in 200 yuan is 100. I hope it helps you.
