Milk thistle is good for detoxification, as is dandelion and licorice root. Magnesium malate and zinc picolinate as well as creatine may help him feel better, especially if he has plenty of muscle ache. I have also gotten plenty of relief from Triple Leaf Detox Tea. Licorice Root Tea tastes great and is very helpful in detoxification. He should also take buffered vitamin c, 1000 mg 2-4 times a day. Magnesium ascorbate or calcium ascorbate would be good.

I tried milk thistle tea, however it is hard to make tea from it, so perhaps an alcohol extract is necessary, even though I hate the idea of using alcohol extracts. Taking capsules of the podered herb might also not result in that much absorption. There may be some other ways to take it though. In general I suggest staying away from supplements that have many different things bundled together(except for example a B50 which is reasonable to get).

I tried to find out what is in OSR. All I found was hype about it, and nothing giving the ingredients in detail. In general, I avoid proprietary supplements in which little information is given about the specific ingredients.
