the OPC's in grapeseed extract go into your bloodstream and repair damage. its one of the supplement with the best scientific evidence that it works. best price on the net by far is swanson.
here is another message of mine i copied about superfood powders. you can make your own superfood powder with schulze's recipe for about 1/10th the price, no exaggeration. all the ingredients can be gotten from mountain rose and/or pacific bo.
------------
mountain rose herbals has some GREAT prices on stuff like barley powder, wheatgrass, spinach, beet roots powders, spirulina, etc. If you want to mix up your own superfood powder thats the place to go.
this is Dr. Schulze 's recipe for his superfood. all of these ingredients can be bought and combined for WAY cheaper than what you pay for his product.
