> Vitamins are fuel - the more intense activities you do, the more you use them.
Vitamins aren't an energy source. They're not burned up.
> if you do bodybuilding or intensive physical or mental exertion, vitamins and minerals from supplements are almost a must.
No they're not. You've been listening to too many bros.
> Most bodybuilders know that a dose of pure protein powder is much more effective for muscle building than any amount of meat or cheese
Most bodybuilders are clueless bros that don't actually read scientific research. Yes, the bioavailability of whey protein powder may be higher than other protein sources but there is very little evidence to suggest it's "much" more effective for building muscle. Possibly more effective before and after a workout, not at other times. There isn't much research into it outside of the workout window either.
> Same goes for glutamine and other supplements, and of course vitamins.
Nope, nope, and nope. There's absolutely no scientific evidence that glutamine is helpful to bodybuilders.
