Hi mrsD,

Something bothers me about that chart, as well as getting study data from the company that mfrs./sells the product. I see that they're citing studies done by others, but IME, purveyors of products do tend to cite only studies that support their claims, even when there are other studies that contradict. (I'm not saying that's the case here - I don't know.)

The bar chart

(is that the one you're referring to?) seems to indicate that Alpha Lipoic Acid is better absorbed than R-Lipoic Acid , when other sources have been telling us that RLA is better absorbed, and we're only needing 1/6 the dose as of ALA.

I guess I'd just feel better about it if there were corroborating independent studies. All those "improved" nutrients - I'm beginning to wonder if at least some of them aren't just so much smoke & mirrors...
