the 4 supplements i'd actually defend buying

after years of trying 20+ things, the ones i always come back to: - creatine monohydrate (5g, muscle + cognition) - vitamin D (if your levels are low, confirm with labs) - magnesium glycinate at night (sleep + muscle) - omega-3 fish oil (if you don't eat fatty fish 2x/wk) everything else was situational or didn't move my bloodwork. save your money.
