Oh, one more thing, grape seed extract is recommended for eye health along with MANY other health issues. I started with it at 57 and my grandson reminds me that at 15 he doesn't forget his daily grape seed ex...he and his 18 yr old sister are on it about 2 yrs now...so they have a good start with their immune system. Their mother also takes it and has been off and on for years but now on and does not miss a day.
You might want to do research on this great antioxidant. Here is an excellent overview on this antioxidant.
