MrsD, so there are fish body oils that have high concentrations of vitamin D3? I suppose there the worry would be the mercury, but perhaps they can and do take it from smaller fish, hence reducing the amount of mercury absorbed. I'll do some research, thank you.

Pinky, we'll be guinea pigs for it at around the same time. I've used some of their products before and have the R lipoic coming too and many others. Yes, I like their products for precisely that reason too. I avoid all fillers and additives to the extent that it's possible, and so far so good, though sometimes it takes me quite a while to find something I need.
