Carnitine and ALA;

I try to read as many bodybuilding mags as i can to try and stay on top of the latest training and nutrition research, whenever i come across something that i think that may be of some help to your training goals regarding bodybuilding and lifting in general, i feel compelled to pass it on.
Carnitine;
Carnitine was just once a popular fat burner, until researchers at the university of connecticut decided to do a series of studies on this supplement. They found that it not only helps to burn fat, but it enhances muscle recovery,boosts insulinlike growth factor-1, and increases the amount of testerone receptors in muscle cells. Since carnitine, much like creatine, requires insulin to get into muscle cells to be effective, it is recommended that it be taken with meals, espically those containing carbs.
Alpha-lipoic acid;
ALA is known as the "universal antioxidant", because its main job in the body is to take care of the other antioxidants. ALA can also increase insulin sensitivity, which means insulin's actions are magnified. That's why you want to stack it with carnitine. Research shows that ALA boosts creatine uptake by muscle and will do the same for carnitine. This is great news for bodybuilders, since insulin is an anabolic hormone that drives protein synthesis and increases the uptake of glucose and creatine into muscle cells.
Stack it like this;
The best time to stack these two is immediately after workouts, with your postworkout protein and carbs. Take in 1-3 grams of carnitine along with 300-500 milligrams of ALA.
I know not everone has the time to sit and read all the new research and magazines that come out all the time so i will try to narrow it down and give you what i think might be helpful on your quest to the physique you desire.Train hard and smart!
