I see the later a lot in the supplement market. I have milk crates full of supplements to handle my various genetic quirks. (Mostly so I don't throw something out only to decide to try it again six months later.) And you can 100% find videos on Youtube saying "No no no, you have to take this in the morning! It's actually bad if you take it before bed." Or "Oh! You bought straight ABC but it didn't have the DFG additive? Yeah your body can't absorb that at all." And the grifters will take it as far as you can swallow. Chirality, manufacturer quality, dosage regimens... any excuse besides 'this product isn't for you, period.'
To be fair, most supplements only make your pee more expensive. I think people just need to buy X, Y and Z to keep themselves motivated in some way, it's more psychological than anything else. You usually have people that are at the end of two extremes, they are either fat motherfuckers who can't stop eating or hungry skeletons that can't be bothered to eat a proper meal.
Honestly? I've given up on all the pseudo-science surrounding fitness, all the studies are paid off by companies that are interested in selling you supplements.
But, i mean, the only reason i say all of this is because i've been working out, on and off, since 2014 (and by that i mean, i would workout a year, stop for maybe 2 or 3, go back, do it for a year etc), so i can say that there really isn't much of a difference in taking supplements versus just eating food.
Just learn how to do your exercises properly, learn how to eat good food (one or two pieces of chicken or beef every meal, or 4 ~ 5 eggs every meal), and just move on with your life. (I'm not talking to you specifically, just to be clear).
Working out is really good for your health and for your mind, but you really can't obsess over this shit unless you are wealthy and semi-retired. A man working 8 hours a day from Monday to Saturday can't stay on top of all of that, even if he's just working on an office or even if he works from home.
Unless the guy has no other interests in life except working out, that is.
