DHEA Side Effects & Safety

Safety Profile

Overall safety rating: Professional Guidance Recommended

Potential Side Effects

  • Acne and oily skin — particularly at doses above 50mg; related to androgenic conversion
  • Hair loss — may accelerate androgenetic alopecia in genetically predisposed men via DHT conversion
  • Gynecomastia — possible due to aromatization to estrogen; risk increases with higher doses
  • Mood changes — irritability, aggressiveness, or mood swings reported at higher doses
  • Elevated estrogen — DHEA can aromatize to estradiol; monitor estrogen levels with blood work
  • IMPORTANT: DHEA is a hormone precursor; self-dosing without blood testing can lead to supraphysiological hormone levels

Drug & Supplement Interactions

  • Testosterone replacement therapy — DHEA adds another androgen precursor; combine only under endocrinologist supervision
  • Aromatase inhibitors (anastrozole) — DHEA increases estrogen precursors; may partially counteract AI effects
  • Insulin and diabetes medications — DHEA may improve insulin sensitivity; monitor blood sugar
  • Anticoagulants — DHEA may affect platelet aggregation; inform physician
  • Hormone-sensitive cancers — DHEA is contraindicated in prostate cancer and breast cancer due to downstream conversion to sex hormones

Maximum Dose

Do not exceed: 100mg daily has been used in clinical studies; doses above 50mg increase risk of hormonal side effects without proportional benefit
