Can you buy supplements like alpha lipoic acid and benfotiamine off the shelf in the pharmacy section of Walmart, or CVS ? I'm off there soon and will stock up if you can.
Thanks
Quality varies so much between brands. I buy most of my vitamins from our local health food store and food co-op, where the quality is better. There you can often ask which brands are the highest quality. For Thorne Research supplements, I order through Amazon.
http://www.consumerlab.com/ tests the contents of nutritional supplements and reports the results, but you have to pay an annual membership fee to access that information.
