Summary
Fixing zinc, magnesium, and vitamin D deficiencies can boost testosterone by 100+ ng/dL. Covers proper testing protocols (timing matters), why free testosterone drops faster than total T with age, and which supplements actually have evidence (boron, ashwagandha, Tongkat Ali).
Key Points
- Testosterone sustains muscle tissue, bone integrity, insulin sensitivity, and neurological health
- Early morning testing when fasted is best; repeat measurements recommended before intervention decisions
- Only 2-3% of testosterone circulates freely; understanding SHBG is crucial for interpreting results
- SHBG increases with age; oral contraceptives suppress testosterone by 50-80%
- Natural optimization addresses micronutrient deficiencies (zinc, magnesium, vitamin D), exercise type, alcohol reduction, and body composition
- Deficiency correction in micronutrients can increase total testosterone by 100+ ng/dL
- Reviews effectiveness of boron, ashwagandha, and Tongkat Ali for testosterone support
Key Moments
Resistance training is the most impactful exercise for boosting testosterone naturally
Heavy resistance training tops the hierarchy for testosterone, followed by HIIT, then moderate exercise.
"Weightlifting at the top. Then some of your more HIIT style workouts underneath that. It has to be something you enjoy enough that you'll adhere to it."
ZMA (zinc, magnesium) reliably boosts testosterone -- but only if you're deficient
Vitamin D, zinc, and magnesium supplementation can meaningfully increase testosterone when correcting a deficiency, but offer limited benefit when.
"The most reliable things that move the needle if you were deficient is the ZMA. It was like the first combo supplement seen as a testosterone booster. It's zinc, magnesium."
