What did @_mattconrad_ actually say?
Conrad checked in on his three-month Hone Health vitamin partnership, saying his "active testosterone is going up" and his energy has improved. He framed this primarily as a convenience story, noting he could "pull out six of these" packets for vacation. He credited the vitamins for the testosterone change, though he never described which vitamins he's taking or what his baseline numbers were.
To be fair, he was transparent about the sponsorship with both a verbal disclosure and hashtags. He also made a reasonable behavioral point: easier routines lead to better consistency. That part is actually supported by behavioral health research. The problem is the leap from "I took vitamins" to "my active testosterone went up" without any acknowledgment of what else might explain that change.
Does the science back this up?
The short answer: some micronutrients have modest evidence for supporting testosterone levels in deficient men, but calling vitamins a reliable testosterone-raiser is a stretch. The effect sizes in the literature are small and context-dependent.
Vitamin D supplementation has the strongest evidence. A 2011 randomized controlled trial by Pilz et al. in Hormone and Metabolic Research found that men supplementing with roughly 3,332 IU of vitamin D daily had significantly higher testosterone levels than placebo after 12 months, but only in men who started out deficient. Zinc deficiency is also linked to lower testosterone, with Prasad et al. (1996, Nutrition) showing that zinc restriction suppressed testosterone in young men. Magnesium shows similar deficiency-dependent associations.
The pattern here matters: these nutrients appear to restore testosterone toward normal range when someone is deficient. They do not appear to push testosterone above normal baseline in men who are already replete. If Conrad was deficient in something and corrected it, a modest rise is plausible. If he wasn't deficient, the vitamins probably aren't driving much.
What did they get wrong (or right)?
The attribution is the problem. Conrad says "my active testosterone is going up" and directly ties that to the vitamins, but he doesn't account for confounders. Three months is also enough time for lifestyle shifts, stress changes, sleep improvements, or weight loss to meaningfully move testosterone. A 2021 review by Leproult and Van Cauter in JAMA showed sleep restriction alone can drop testosterone by 10-15% in young men. Fix the sleep, testosterone comes back up. Vitamins don't get the credit.
He also uses the term "active testosterone" without explanation. This likely refers to free testosterone rather than total testosterone, which is a more clinically relevant marker, but the casual framing implies the vitamins have a specific mechanism on bioavailable hormone. No standard vitamin supplement has a demonstrated direct effect on sex hormone binding globulin (SHBG) that would shift free testosterone. That claim has no backing in current literature.
What he got right: the consistency argument holds. Adherence to any supplementation protocol improves outcomes, and pre-packaged convenience genuinely helps. That's not a trivial point.
What should you actually know?
If you're watching this video and wondering whether vitamins can raise your testosterone, here's the honest version. First, get your levels tested before spending money on anything. Hone Health does offer at-home hormone testing, which is a legitimate starting point. But a vitamin protocol built without knowing your actual deficiencies is guesswork.
Second, understand what "testosterone optimization" through supplements actually means in practice. The studies that show benefit are almost entirely in deficient populations. A 2020 meta-analysis by Cinar et al. in Biological Trace Element Research found zinc supplementation raised testosterone in athletes under physical stress, a specific population, not the general public.
Third, if your testosterone is genuinely low and affecting your quality of life, vitamins are unlikely to move the needle enough to matter clinically. That's a conversation about actual hormone therapy, not a supplement packet. Personalized vitamins have a real place in filling dietary gaps. Marketing them as testosterone-raising tools requires a lot more asterisks than this video includes.
