ALA is made by many vitamin companies. The problem is that only a few brands make 50 mg tablets or capsules. Larger sized tablets or capsules are easy to find.

Over the counter DMSA is available from a few sources. Many use Captomer(DMSA made by Thorne Labs) or DMSA made by VRP. VRP is the only company I know of that has 25mg ALA capsules. The other makers make only 100 mg and/or 250 mg capsules. I have no idea if Whole Foods sells DMSA. They probably sell ALA though. Most people buy DMSA over the net since few stores sell it. Prescription DMSA(Chemet) probably costs around $3 per 100 mg capsule, vs around 85 cents for over the counter DMSA. Some people have good prescription insurance coverage so their best option is to get prescription DMSA.
