DHEA (Dehydroepiandrosterone) vs Omega-3 (EPA/DHA)

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

EPA and DHA incorporate into cell membrane phospholipids, modulating membrane fluidity and lipid raft signaling. EPA competitively inhibits arachidonic acid conversion via COX-2 and 5-LOX, reducing pro-inflammatory eicosanoids (PGE2, LTB4) while generating anti-inflammatory resolvins and protectins. DHA is critical for neuronal membrane integrity, modulating BDNF expression and synaptic plasticity via Nrf2 and NF-kB pathways.

Standard Dosing

2-4g combined EPA/DHA daily (targeting 2:1 EPA:DHA ratio for inflammation; 1:1 for cognitive)

Timing

With meals containing fat for absorption. Split dose AM/PM.

Cycle Duration

ongoing

Side Effects

• Fishy burps/aftertaste
• Mild GI upset
• Loose stools at high doses
• Potential increased LDL in some individuals

Contraindications

• Active bleeding disorders
• Scheduled surgery (discontinue 2 weeks prior)
• Fish/shellfish allergy (use algal-derived)
