How it works
D-Aspartic Acid acts on the hypothalamus and pituitary gland to stimulate the release of luteinizing hormone (LH). Increased LH then signals the testes to produce more testosterone. Effects are dose-dependent and typically observed within 4-12 weeks.
Who should take it
Adults looking to address hormonal imbalance, low libido, irregular cycles. Particularly relevant for people who prefer a targeted single ingredient and who have ruled out an underlying condition that needs medical care first.
Avoid / careful
Pregnant or nursing women without clinician oversight. People on prescription medication affecting the same pathway should consult a doctor before combining. Side effects are uncommon at recommended doses but mild GI upset can occur when starting.
