Russ, there are a few brands which make 50 mg ALA. 25 mg is hard to find or expensive. Besides the magnesium malate, I believe creatine has also helped reduced my muscle pain.

Turmeric is also very helpful while using ALA. Turmeric increases bile production. ALA rids the body of mercury mostly through bile leving the digestive system. Increasing fiber intake may also help to have less bile reabsorbed and reused by the body.
