Why not as calcium/magnesium/zinc-ascorbate?

there are no benefits over ascorbates over ascorbic acid... ascorbates are actually weaker antioxidants and are more expensive.

One benefit an ascorbate may have is less stomach discomfort. Although since the dosage is lowish to begin with, I don't think ascorbic acid would be that big a problem for most.

What about something like Pureway C? I never tried it, but there is a little data suggesting it may be better than regular ascorbic --

Another option is a purely food based C, like acerola or amla. It may provide some extras, like bioflavonoids, and components of food missing from ascorbic, but it'd be more expensive and bulky in the capsule.

One possible plus for food based is it could be a good selling point. People generally prefer natural food-based nutrients when possible. Or Pureway, assuming their studies are correct -- you could claim a benefit over regular ascorbic on the label.

I do not think a majority would prefer food-based ingredients. The suggested food-based sources of Vitamin C pose additional problems in that the tannins they contain would reduce the bioavailability of various minerals in the formula.

Pureway-C is an interesting option that would help our supplement stand out, and it does have a few published studies (although these are probably conducted by the manufacturer). If this is deemed too expensive, impractical or otherwise undesirable then just use ascorbic acid.

i agree about not using acerola and looking into pureway or one of the other patented vitamin C's with a bit of research behind it.

Wow. That sounds really promising. ... what the fuck is it?

Well, I'd like to see this included. At 500mg+. Maybe even 1g. I see no reason to limit the vitamin C intake to the RDA, and there are studies out there that show that 500mg DOES provide benefits. I don't feel like digging them all up right now, but they're out there.

If the Pureway turns out to be super expensive, 500mg would suffice. And those are SOME claims. Whoever's looking into this, keep us posted.

Also, perhaps adding synergists would be a good idea. Quercetin, other bioflavs (Rutin and Hesperidan in particular), and some say there is increased uptake using threonic acid (a vitamin C metabolite) alongside it. That's something I'd consider worth looking into, as well.
