I use to take the expensive high potency multi vitamins. Then in addition take extra C, E, and a B complex. Just a waste of money. Taking extra doesn't mean it improves health. You just need enough the stop disease from a vitamin deficiency. I go to Walmart and buy the cheapest multi they have. Due to law suits what's on the label is what's inside. Supplements are completely unregulated.
Guys taking whey protein, multi vitamin, extra individual vitamins, creatine, energy drinks, and who knows what else is wasting money. It took a long time before I felt secure enough to stop the nonsense. I still think I need a protein supplement. Maybe I will go back but so far truth be told I'm in fantastic shape without it. No not in the bodybuilding mirror athlete look but as a real athlete.
