Q&A: Folic Acid, MTHFR, Vitamin D3 & Testosterone | TUH #299

About this video

In a solo Q&A answering his twelve most-asked questions, Brecka clarifies he is a human biologist, not a doctor, recounts his mortality-prediction career, and confirms he uses hormone replacement therapy. He discusses weight loss, his daily eating approach — arguing no single dogmatic diet extends life — MTHFR and methylfolate, vitamin D and testosterone questions, and how people outside the US can access testing.

Key takeaways

• Brecka states his background is biology degrees plus two decades as a mortality expert, not medical licensure
• He confirms he is on hormone replacement therapy and discusses testosterone questions from viewers
• Brecka claims MTHFR is among the most common gene variants and links it, in his telling, to anxiety, ADHD and miscarriage risk
• He argues extending life is about whole-food eating rather than allegiance to carnivore, keto, vegan or any single diet
