Protein supplements and multivitamins are simply excreted by the body. A balanced and healthy diet is all that is needed. If your doctor runs a lab panel that shows a deficiency, then you would need supplementation. But the vast majority of us are just fine without any of that stuff.
Creatine is also a myth and in your head. It simply causes you to retain water. The body can not process the massive amounts of creatine in a supplement.
In a double blind study, creatine had no more effect than a placebo in regards to improving endurance. Studies also found that combining with caffeine, common in supplements, completely obliterates all effects of creatine.
