Rated 1 out of 5 by from Grapefruit seed extract? This is certainly not as good a product as I am used to having. I opened a capsule to test the grapefruit seed strengh and could hardly taste it ! I have excellent taste buds and they should have went nuts with the purported amount of extract. Instead it was a sweet taste with very little grapefruit taste. I would be surprised if there was even 100mg. in the cap. Also when I take two caps of the other product(100mg)I know its working . This stuff I take 4 caps and still notice nothing!
