DHEA (Dehydroepiandrosterone) vs Resveratrol

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

Resveratrol activates SIRT1 (the longevity sirtuin) via allosteric binding, promoting deacetylation of PGC-1alpha (mitochondrial biogenesis), FOXO3 (stress resistance), and p53 (DNA repair). It inhibits NF-kB and COX-2, reducing chronic inflammation. Resveratrol also activates AMPK independently of SIRT1 and inhibits phosphodiesterases (PDEs), raising cAMP levels. It improves endothelial function via eNOS upregulation and NO production.

Standard Dosing

250-500mg trans-resveratrol daily

Timing

Morning with a fat-containing meal. Often taken alongside NMN for synergistic sirtuin activation.

Cycle Duration

ongoing

Side Effects

• GI upset/diarrhea at high doses
• Headache
• Joint pain (rare)
• Insomnia (if taken late)

Contraindications

• Estrogen-sensitive cancers (theoretical ER agonism)
• Bleeding disorders
• Pregnancy/lactation
