Seven Supplement Myths Men Still Believe

Myth 1: more is better

Dose-response curves flatten and often reverse. Fat-soluble vitamins accumulate; excess zinc interferes with copper absorption; high-dose concentrated green tea extract carries rare liver-injury reports.

The label serving is not a suggestion to beat.

Myth 2: natural means safe

Nicotine, digoxin and ricin are all natural. Origin says nothing about safety profile. The relevant questions are dose, interaction and individual susceptibility.

Myth 3: supplements are FDA approved

They are not. The FDA does not approve dietary supplements before sale — a point stated plainly in its own guidance. Facility registration is a legal requirement, not an endorsement.

Myth 4: if it were useless it would be banned

The regulatory framework places the burden on authorities to demonstrate harm, not on manufacturers to demonstrate benefit before sale. Presence on a shelf is not evidence of efficacy.

Myth 5: you need a loading dose

True for creatine, where it shortens time to saturation, and largely irrelevant for botanicals, where the concept has been borrowed without justification.

Myth 6: expensive means better

Price reflects marketing spend, packaging and margin at least as much as formulation. Cost per day against published dosages is the meaningful comparison.

Myth 7: you can feel it working

You can feel stimulants. You cannot feel nutrient repletion, and you generally cannot feel adaptogenic support in real time. Judging by sensation systematically favours the products doing the least.
