I recently read a study that showed the difference between the hundreds of supplement choices. It was an independent study concluding that the difference in the many supplements is the amount of vitamin product that actually reaches the cell. All seem to have the right ingredients, but some are unable to get those ingredients to the cellular level. (ie. the cell does not absorb much of the product)

According to the study, the vitamin I was taking at the time was only getting 5% of its contents to the cellular level.

I post this question to tap the amazing mind that is (sometimes) Slowtwitch. I do not have a link to the study because it was a hard copy.

Any insight into this?
