The Verdict
2 of 5 experts actively discuss selenium supplementation. Hyman is the strongest advocate, citing selenium across 19+ videos for thyroid function, immune defense, glutathione production, and detoxification. Huberman covers selenium's role in thyroid hormone production across 3 videos. Patrick, Attia, and Johnson have no direct selenium coverage in analyzed videos.
Where They Disagree
Only 2 of 5 experts have direct selenium coverage. Attia, Patrick, and Johnson do not discuss selenium as a standalone supplement in any analyzed video, suggesting it may not be a priority in their protocols.
Hyman frames selenium primarily through thyroid health and detoxification, while Huberman discusses it mainly as a thyroid support nutrient — neither positions it as a standalone longevity supplement.
