Mechanism

DHEA is the most abundant circulating steroid hormone, produced primarily by the adrenal zona reticularis. It serves as a precursor for both androgens (testosterone, DHT via 3beta-HSD and 17beta-HSD) and estrogens (estradiol, estrone via aromatase). DHEA-S (sulfated form) acts as a neurosteroid, positively modulating NMDA receptors and antagonizing GABA-A receptors (cognitive enhancement/alertness). It also modulates immune function (enhances Th1 immunity, IL-2 production), supports bone mineral density via estrogenic metabolites, enhances insulin sensitivity via PPAR-alpha activation, and opposes cortisol's catabolic effects (DHEA:cortisol ratio is a stress/aging biomarker).

Standard Dosing

25-50mg daily (men); 10-25mg daily (women)

Timing

Morning (mimics natural circadian peak). With food.

Cycle Duration

Ongoing under supervision with regular blood monitoring (DHEA-S, testosterone, estradiol, PSA in men)

Side Effects

  • Acne (androgenic)
  • Hair loss (androgenic)
  • Hirsutism in women
  • Mood changes (irritability, aggression)
  • Deepening of voice in women (at high doses)
  • Insomnia
  • Oily skin

Contraindications

  • Hormone-sensitive cancers (prostate, breast, ovarian)
  • PCOS (may worsen androgen excess)
  • Endometriosis
  • Uterine fibroids
  • Children/adolescents

Mechanism

Sulforaphane is the most potent natural activator of the Nrf2-ARE (antioxidant response element) pathway. It modifies Keap1 cysteine residues, releasing Nrf2 to translocate to the nucleus and upregulate >200 cytoprotective genes including NQO1, glutathione S-transferases, heme oxygenase-1, and UDP-glucuronosyltransferases (Phase II detox enzymes). It also inhibits HDAC activity (epigenetic modification), induces Phase II/III xenobiotic metabolism, and suppresses NF-kB inflammatory signaling.

Standard Dosing

10-30mg sulforaphane daily (equivalent to ~100-200mg broccoli seed extract standardized to glucoraphanin + myrosinase)

Timing

On empty stomach or with light meal. Myrosinase enzyme required for conversion from glucoraphanin — ensure supplement contains it or add mustard seed powder.

Cycle Duration

ongoing

Side Effects

  • Gas/bloating
  • Mild GI discomfort
  • Thyroid concerns at very high doses in iodine-depleted individuals

Contraindications

  • Hypothyroidism with iodine deficiency (goitrogenic potential)
  • Pregnancy (insufficient high-dose data)
