What did @donxstarke actually say?
The claim is that four nutrients, zinc, vitamin B12, selenium, and copper, are "four ingredients that control those hormones" like testosterone and estrogen. If you're deficient in them, your body can't produce enough sex hormones, which means you'll look less masculine or feminine. He also referenced a man with "Wilkins disease" whose face allegedly normalized after receiving "synthetic zinc." The prescription for viewers: get these nutrients through food like beef liver, or take supplements if you can't afford whole foods.
He frames this as "hormone optimization," positioning supplements as a practical alternative to HRT. It sounds specific enough to be credible, and some of it is grounded in real biology. But the framing inflates what the evidence actually supports, and at least one medical claim appears to be fabricated or badly garbled.
Does the science back this up?
Partially, but not the way the video implies. Zinc deficiency is the strongest case here. Research does show that severe zinc deficiency suppresses the hypothalamic-pituitary-gonadal axis, reducing testosterone production. Prasad et al. (1996, Nutrition) demonstrated that zinc restriction in healthy men led to significant drops in serum testosterone, and supplementation restored levels. That's real.
Selenium plays a role in thyroid hormone metabolism, not directly in testosterone or estrogen synthesis. A Cochrane review (Rayman, 2012, Lancet) found selenium supplementation benefits are largely limited to people who are already deficient. Copper is essential for enzyme function broadly, but linking copper deficiency directly to reduced sexual dimorphism is a stretch not well-supported by clinical literature. Vitamin B12 is important for neurological function and red blood cell production. Its connection to testosterone or estrogen levels is indirect at best and not established in controlled trials as a driver of "hormone optimization."
So the video takes one solid data point (zinc and testosterone in deficiency states) and extrapolates it into a sweeping theory about four nutrients controlling how masculine or feminine you look. That extrapolation is not supported.
What did they get wrong (or right)?
The video gets a few things genuinely right. Zinc deficiency can suppress testosterone. Nutrient deficiencies broadly can impair endocrine function. Whole food sources like beef liver are legitimately rich in zinc, copper, and B12. These are defensible statements.
But here's where it goes off the rails. "Wilkins disease" is not a recognized medical diagnosis. The closest real condition is Wilson's disease, a genetic disorder of copper metabolism where the body accumulates excess copper, not a deficiency. It does not cause facial changes reversed by zinc supplementation. Citing it as a "case study" for this argument is either a serious mix-up or invented. Either way, it shouldn't be taken as evidence for anything.
The bigger conceptual error is treating "looking more masculine or feminine" as a direct output of nutrient levels in people who are not clinically deficient. For someone with normal zinc status, adding more zinc does not raise testosterone meaningfully. Maggio et al. (2013, Nutrients) found associations between zinc and testosterone, but those findings apply primarily to deficient or elderly populations, not healthy adults doing a "glowup."
Framing supplementation as "hormone optimization" for aesthetics, without any mention of blood testing, baseline deficiency status, or medical guidance, is a real problem here.
What should you actually know?
If you're eating a reasonably varied diet, you are probably not deficient in these four nutrients, and supplementing them will not change your hormone levels or how you look. The body tightly regulates testosterone and estrogen through the HPG axis. Nutrient repletion corrects deficiency. It does not supercharge hormones beyond your genetic baseline.
If you genuinely suspect a hormonal issue, the starting point is bloodwork, not a supplement stack. A proper workup includes total and free testosterone, SHBG, LH, FSH, and thyroid panels, ordered by a licensed clinician. Zinc, selenium, and B12 levels can also be tested directly. Treating confirmed deficiencies under medical supervision is appropriate. Guessing based on TikTok advice is not.
The "hormone optimization" framing in this video sidesteps what actual hormone optimization involves: diagnosing a clinical imbalance, understanding the cause, and treating it appropriately, which sometimes means lifestyle changes, sometimes means medication, and sometimes means nothing because your labs are normal. Supplements marketed as hormone regulators occupy a largely unregulated space. The FTC and FDA have both taken action against companies making unsupported testosterone-boosting claims.
- Zinc deficiency is real and does affect testosterone, but you need to be actually deficient for supplementation to matter.
- "Wilkins disease" as described in this video does not appear to be a real diagnosis. Wilson's disease is a copper overload disorder, not a deficiency state.
- B12 and selenium have no established direct role in testosterone or estrogen synthesis in non-deficient adults.
- Get bloodwork before spending money on supplements targeting hormones.
