    Testosterone Support

    Natural testosterone optimization for energy, muscle, and vitality.

    TL;DR

    Most testosterone loss is explained by excess body fat, poor sleep and low activity. Supplements only help meaningfully when they correct a deficiency.

    Why It Matters

    Total testosterone declines roughly 1% per year after age 30, but the sharper drops seen in practice usually track obesity, sleep apnoea, alcohol, opioid use and inactivity rather than age. Adipose tissue aromatises testosterone to oestradiol, making fat loss one of the most effective interventions. Symptoms should always be interpreted alongside morning total and free testosterone, SHBG and LH, since low LH with low testosterone points to a secondary cause worth investigating. Testosterone-boosting supplements typically report percentage changes within the normal range that produce no symptomatic difference.

    How to Measure

    Biomarkers

    Morning total testosterone
    Free testosterone
    SHBG
    LH and FSH
    Oestradiol
    25(OH)D
    Serum zinc
    Fasting insulin

    Optimization Protocol

    1) Lose excess visceral fat, since adipose aromatase conversion is a leading driver of low testosterone in men under 50. 2) Sleep 7-9 hours; one week of 5-hour nights lowers testosterone by 10-15% in healthy young men. 3) Screen for and treat sleep apnoea, a frequently missed cause. 4) Resistance train regularly, which supports androgen signalling and body composition. 5) Correct vitamin D and zinc deficiency, the two nutrients with real evidence in deficient men. 6) Cut heavy alcohol intake, directly toxic to Leydig cells. 7) Avoid chronic energy restriction and overtraining, which suppress the gonadal axis. 8) Get properly tested before treating, using a morning sample repeated on a separate day.
