Comparison
Ashwagandha vs Clomiphene
Side-by-side of Ashwagandha and Clomiphene. Every row below is pulled from the compound schema and will update as our data grows. For deeper reads, follow through to each compound page.
Ashwagandha
Ashwagandha supplement guide: KSM-66 and Sensoril extracts at 300-600 mg/day cut morning cortisol and stress in RCTs. Dose, side effects, testosterone data.
Clomiphene
Clomiphene citrate raises LH/FSH and endogenous testosterone in men. SERM TRT alternative, 25 to 50 mg, fertility preserved, visual side effects flagged.
Effects at a glance
Ashwagandha
- •Reduces morning serum cortisol by ~20 to 30% at 300 to 600 mg/day standardized extract over 8 weeks
- •Lowers subjective stress on DASS-21 and PSS scales versus placebo in chronically stressed adults
- •Modest grip-strength and 1-RM gains of ~5 to 8% in trained men when paired with resistance training
- •Improves self-reported sleep quality and onset latency in adults with insomnia symptoms
- •Small testosterone increases (~10 to 15%) reported in stressed or subfertile men, less clear in healthy populations
- •May raise free T3 and T4; can interact with levothyroxine and unmask subclinical hyperthyroidism
Clomiphene
- •SERM that blocks estrogen-receptor negative feedback at the hypothalamus, raising LH and FSH
- •FDA approved 1967 for ovulation induction in anovulatory women at 50 to 100 mg cycle days 5 to 9
- •Off-label in men at 12.5 to 25 mg daily raises endogenous testosterone while preserving fertility
- •Enclomiphene (trans-isomer) is preferred for male use; cleaner PK and less estrogenic side effect burden
- •Visual disturbances occur in ~1 to 2% of users; persistent symptoms warrant immediate cessation
- •Letrozole has displaced clomiphene as first-line ovulation induction in PCOS (Legro 2014)

Safety profile
Ashwagandha
Common side effects
- mild GI upset
- drowsiness
- headache
Contraindications
- pregnancy
- autoimmune disease (theoretical immune stimulation)
- hyperthyroidism
- concurrent sedative use
Interactions
- benzodiazepines: additive CNS depression(moderate)
- thyroid hormone (levothyroxine): may raise T3/T4, altering dose requirements(moderate)
- immunosuppressants: theoretical antagonism via immune stimulation(moderate)
Clomiphene
Common side effects
- hot flushes
- mood changes
- abdominal discomfort
- breast tenderness
- visual disturbances (rare)
- headache
Contraindications
- pregnancy
- active liver disease
- ovarian cysts (not PCOS-related)
- uncontrolled thyroid or adrenal disorder
- abnormal uterine bleeding of undetermined origin
- hormone-sensitive cancer
Interactions
- tamoxifen: competing SERM activity; not used together(moderate)
- ospemifene: competing SERM activity(moderate)
- anastrozole: additive estrogen reduction; sometimes combined in male protocols(minor)
- TRT (exogenous testosterone): TRT suppresses HPT axis that clomiphene targets; do not combine(moderate)
Which Should You Take?
Ashwagandha comes out ahead for most readers on the criteria we weight: 3 catalogued goals, OTC dietary supplement, oral dosing, with a Tier-B outcome catalogued. Clomiphene is the right call when one of the conditionals below applies.
- → If your priority is stress and HPA-axis regulation, pick Ashwagandha.
- → If your priority is focus or working memory, pick Ashwagandha.
- → If your priority is fertility, pick Clomiphene.
Edge case: If you want to avoid prescription-only, Ashwagandha is the more accessible choice.
Default choice: Ashwagandha. Lower friction to source, and broader goal coverage. Reach for Clomiphene only if your priority sits squarely in the goals it owns above.
