Yeah, I have to take vitamin C liquid capsules along with iron supplements because I have iron deficiancy anema that's hereditary. If I don't, then the iron is ineffective as it needs vitamin C to help aide with absorption. Personally, I think a good vitamin C supplement is good for any skin lightening regimine, along with overall health. And also looking for products that has a good amount of vitamin C amount in them is a plus too. Yeah, I'll check out the long hair care forum that you have mentioned and read up on the Alpha lipoic, thanks.
