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

Multi-strain probiotics colonize the gut mucosa and exert effects via multiple mechanisms: competitive exclusion of pathogens, production of short-chain fatty acids (butyrate, propionate, acetate) via fermentation of prebiotic fibers, strengthening of intestinal tight junctions (via occludin and zonulin modulation), modulation of gut-associated lymphoid tissue (GALT, ~70% of immune system), production of bacteriocins (antimicrobial peptides), and bidirectional gut-brain axis signaling via the vagus nerve affecting serotonin, GABA, and BDNF levels.

Standard Dosing

25-100 billion CFU daily (multi-strain, 8+ strains)

Timing

On empty stomach (morning before breakfast, or bedtime). Some strains survive better with food — follow specific product guidance.

Cycle Duration

ongoing

Side Effects

  • Bloating/gas (usually transient, 1-2 weeks)
  • Mild diarrhea during adjustment
  • Brain fog or D-lactic acidosis (rare, with Lactobacillus overgrowth)
  • Histamine intolerance flare (strain-dependent)

Contraindications

  • Severe immunosuppression (risk of probiotic bacteremia/fungemia)
  • Short bowel syndrome
  • Central venous catheter (risk of Saccharomyces translocation)
  • Acute pancreatitis (PROPATRIA trial warning)
