A cabinet full of bottles you bought off an ad, a gym buddy's recommendation, or whatever was trending that month. No idea if you're actually deficient in any of it. No idea if you're taking it at the right time, in the right form, or with the right food, which changes whether it does anything at all. Most men's supplement routines are expensive guesswork.
Ashwagandha taken in the morning works against your natural cortisol spike instead of with it. Magnesium in the wrong form barely absorbs. Half the men I test are low in something specific, zinc, vitamin D, omega-3s, and are taking none of those while spending money on things their labs never asked for.
What I test: the Vitamin & Antioxidants Test, the Optimal Vitamin D Test, and the Omega-3 & Inflammation Test, so your stack is built from your own numbers instead of a trending list.
What this looks like in practice: a short, specific list of what you actually need, when to take it, and why, not a shelf full of bottles you're not sure are doing anything.
