Not to come down on you too hard, but do you even know biochemically what a vitamin is? Seriously, without googling it up right this second? Bio-availability varies from product to product depending on time to dissolve
not absorb. Imagine a multi-vitamin as a tall building and your body needing to take a wrecking ball to it to absorb the individual bricks. Enzymes in your body then turn these "bricks" which are actually vitamins into coenzymes needed for biochemical functions such as carbohydrate metabolism (B12) and amino acid metabolism (Folic Acid). A multi-vitamin doesn't create some super-duper sized Vitamin C "particle" that the body can't "absorb", rather, it might have difficulty breaking down the vitamin as a whole. Even this whole "bioavailability" argument is one most often mentioned by alternative vitamin companies that offer "natural" versions of vitamins. At a price, of course. The problem is that "bioavailability" vastly depends on the person's digestive system. Babies/pregnant or nursing mothers are often given a specific kind of multi-vitamin which does break up more easily because a baby's digestive system has a harder time processing such things. But for the average adult? Not that big of an issue. Most people, however, can literally see their vitamins working when their pee comes out bright yellow because of the excess B2 in their blood. If Vibe works for you, by all means, keep using it. But the science behind your explanation needs a touch more refinement.
