I'm not talking "oil", there is grape seed oil that is used for salad dressing, I don't use it. I'm talking the grape seed extract capsules and if one has a chronic issue like allergies, it's recommended to updose for a while to saturate your body tissues to get things going. So if you say weigh 100 lbs, take 200mg daily or a little more if you don't have issues taking it. If you weigh 200 lbs, then 400mg or more a day. I've heard from a few who say they can't take it, have stomach issues or an allergy to grapes...I've NEVER had issues in the 20 yrs soon. Yes, keep me posted and do get the correct supp.
