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

Mechanism

Glucosamine serves as a substrate for glycosaminoglycan (GAG) and proteoglycan biosynthesis in articular cartilage. It stimulates chondrocyte production of type II collagen and proteoglycans while inhibiting MMP-3 and aggrecanase enzymes that degrade cartilage matrix. Chondroitin sulfate provides osmotic swelling pressure in cartilage (water retention), inhibits complement-mediated inflammation, and downregulates NF-kB and IL-1beta in synoviocytes. Together they exert synergistic chondroprotective and mild anti-inflammatory effects.

Standard Dosing

1500mg glucosamine sulfate + 1200mg chondroitin sulfate daily

Timing

With meals, split into 2-3 doses. Full clinical benefit requires 8-12 weeks of consistent use.

Cycle Duration

ongoing (minimum 3 months to assess response)

Side Effects

  • GI upset/nausea
  • Heartburn
  • Diarrhea or constipation
  • Drowsiness (rare)
  • Headache

Contraindications

  • Shellfish allergy (if shellfish-derived glucosamine — use vegetarian/fungal source)
  • Active bleeding with anticoagulant therapy
