FYI...this supplement has only a 4-6% absorption rate (ie. what actually goes IN to our cells). ANY brand you buy from a drug or grocery store are "bed pan bullets"...you pee all the good stuff (if there is any) down the toilet.
If you're looking to get on a supplement regimen, the best places to get high-quality is from a health care practitioners office (Naturopath, Holistic Nutritionist, Chiropractor, etc.) or even a good health food store.
Don't waste your money....if it IS that cheap...just think of what is (or isn't) actually in the bottle!
Here are some examples of some of the best companies:
Metagenics
Genestra
Melaleuca - Vitality For Life
