Are supplements a meme?

Title, are supplements pure bullshit or do some of them actually work?

Right now i take Protein powder and creatine.

Creatine did jack shit for me.

Protein is useful if you struggle to hit your macros otherwise.

Anything more than .8g/lb is unnecessary, tho

Apparently yohimbine hcl works ok but I doubt it. Creatine is good

Nah.
I still have half a bottle of yohimbine that i will probably never use

I think it only works for people who didnt fast already, as it makes you abide by a fast.

If you do the fast without the Yhcl you get the same results, maybe even slightly better

Supplements work best when you're really pushing it in the gym.

Meaning if you're pushing intensity, volume and periodization...AND you eat enough and get restful sleep, then supplements are great.

If you're not really pushing it, then just fuckin eat food and maybe have coffee before a workout as a preworkout.

Otherwise, don't waste your fucking money. Buy food, prep it, cook it, and eat it yourself.

my sups are Multivitamin, preworkout with creatine and citrulline malate (and coffee). The rest is just food.

They do work. I'd be more worried for the health effects of pure, concentrated and easy to process macros.

E.g. gainers and their use pattern have high potential for triggering diabetes. Sometimes i wonder if easy to process protein doesn't reduce ones ability to gain proteins from real foods etc.

Nah.

Protein bioavailability has little to nothing to do with "tolerance" and almost everything to do with fiber intake.

I kinda eat a not amazing diet, are vitamins worth it? Starting to get zombie mode.

Vitamin D is a must

Why not eat a better diet?
