The dietary supplement industry is such a mixed bag these days. It has such promise, but often fails to deliver. For example, garlic pills were once the number one herbal supplement. But studies showed most garlic pills failed to deliver the active ingredient produced by fresh-crushed garlic cloves. Subsequently garlic pills fell from their top-seller spot. Turns out that stomach acid destroys the enzyme (alliinase) that produces the active ingredient allicin. Only if a garlic clove is crushed outside the acidic stomach is allicin produced. Only enteric-coated or buffered garlic tablets produce what a fresh-crushed clove of garlic delivers.
