When I was riding a couple hundred miles a week on my bicycle... I took two supplements, Alpha Lipoic Acid and Acetyl-L-Carnitine, they supposedly helped increase the rate that fat could be metabolized on long rides when the carbohydrate stores in my muscles became depleted. They were also intended to reduce oxydative stress on muscles used in strenuous exercise. They seemed to improve my comfort level and the recorded times on my 40 and 60 mile training rides. It was significant enough that it seemed to be more than just a placebo effect.
Unfortunately, they also seemed to cause me to have stinkier gas and body odor that my wife objected to... so I had to quit using them. But they are the only supplements that I have ever taken that really seemed to have any meaurable effect.
Ten or so years later my dad was perscribed the two supplements because they were shown to reduce the damage caused to the heart muscle after someone had a heart attack.
I do take a multivitamin to try and help make up for a diet that is not as diverse as it probably should be. But I do not really believe the claims made about most supplements sold that make so many “promises” that are not really backed up by studies on their effects on humans.
