JUst everyday. Sorry my computer broken so just saw this. I sell grape seed out of my house to others so guess I am sort of a professional. I buy dried red gradpe seeds and ground them in blender and put them in caps. Make sure you put in caps not made from pigs. I use dried fennel, excellent. I get my olive leaf off of trees outtside my house and dry them and then grind them, they are very fine so I add a little grape seed to them for texture. I also use tumeric, ginger, kelp etc. Go natural and it is better for you.
