I appreciated everyone's response to my query about grape seed extract.

Thanks, Dave, for the link you gave. It looks very interesting. Jo*Mar, appreciate the reminder about labdoor.com. I have used this site before. Found it very helpful in selecting a whey protein to use. Thanks, Caroline, for all the detailed information and the link you gave in your second post. Am going to re-read it again today. And appreciate, Sylvie M., your note of caution about solvent use.

I do appreciate everyone's help.
