This is simply a concoction of herbs plus cheap ferrous gluconate (you can buy a bottle 100 tabs of ferrous gluconate from your drugstore for about 5$). It hurt my stomach just as badly as the ferrous gluconate tablets did, made me constipated and that makes me cranky - especially when I spent a lot of money on this stuff...If you just want a liquid supplement, try geritol - its way cheaper and works just as well and honestly does not hurt my stomach as much as this did.
