mmmm... let me guess

maybe is because the formula it's usually for old people (who have the stomach acid low) then it will make the formula more acid? then can absorb better?

Hi James, i'm just curious about the ingredient in your bone-joint formula: Vitamin C crystals

maybe i'm wrong, but, it is not the same as synthetic ascorbate acid?

i think there are some reasons for it's use

i'm just curious about it   cause you always say that vitamin C in most of natural forms (excpt camu camu) contain synergistic compounds that protect this antioxidant from oxidation.

There are natural vitamin C sources in the formula as well because I do not use the ascorbic acid for the vitamin C activity.  It is actually added as an acidifier to help increase absorption of the nutrients in the formula.  The vitamin C in the herbs does not always provide the acidity since the vitamin C is generally buffered by the minerals in the plants.   When I first started making the formula I did not have access to other acidifiers such as malic acid so I went with the ascorbic acid.
