Started my career at a supplement company and it is definitely heresy, deception, and weird derivatives of protein and caffeine.

Multiple sources can hardly be considered an effective bar to decide if something as a whole is good or bad for you. The author completely misses major pieces of literature around these and citing something that is critical for you body as 'probably good for you' while not covering a single instance of health problems from deficiencies makes it hard to take this seriously.

No pondering necessary. That entire industry is based on making implications with statements and lobbying to avoid any potential accountability.

I agree - its hearsay and deception - vitamins and nutrients and dietary supplements are a huge, profit driven, industries - they are not your friend trying to improve your health - they are trying to empty your wallet and nothing else.

Selling water / sugar that has been "marketed differently" (read: they lie to you) is a huge industry, yes.

E.g. "Vitamin Water", all kinds of supplements marketed in the fitness industry, even https://en.wikipedia.org/wiki/Homeopathy.

Placebo is a strong thing.
