Comparison
Clomiphene vs Glutathione
Side-by-side of Clomiphene and Glutathione. 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.
Clomiphene
Clomiphene citrate raises LH/FSH and endogenous testosterone in men. SERM TRT alternative, 25 to 50 mg, fertility preserved, visual side effects flagged.
Glutathione
Glutathione (GSH) is the body's primary intracellular antioxidant. Oral supplementation has variable bioavailability; sublingual, liposomal, and IV forms.
Effects at a glance
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)
Glutathione
- •Body's primary intracellular antioxidant; tripeptide of glutamate, cysteine, glycine
- •Oral bioavailability poor; sublingual, liposomal, IV more reliable
- •Richie 2014 trial showed body GSH store increases at 250-1000 mg/day for 6 months
- •NAC supplementation often more cost-effective indirect strategy
- •Modest signals in NAFLD, skin aging, immune support; weak in cardiovascular

| Molecular formula | C26H28ClNO | C10H17N3O6S |
| Mechanism | Selective estrogen receptor modulator that antagonizes estrogen at the hypothalamus and pituitary, increasing GnRH and gonadotropin output, which drives gonadal steroidogenesis. | Tripeptide antioxidant; substrate for glutathione peroxidase (H2O2 reduction), GST (xenobiotic conjugation), glutaredoxin (redox signaling). GSH:GSSG ratio is the central cellular redox indicator. |

Safety profile
Clomiphene
Common side effects
- hot flushes

- 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

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)
Glutathione
Common side effects
- mild GI upset
Contraindications
- asthma (IV / inhaled forms specifically)
- active chemotherapy without oncologist guidance
Interactions
- chemotherapy agents: theoretical interference with GSH-depletion-dependent agents(moderate)
Which Should You Take?
Glutathione 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 hormonal optimization, pick Clomiphene.
- → If your priority is fertility, pick Clomiphene.
- → If your priority is liver function, pick Glutathione.
- → If your priority is healthspan extension, pick Glutathione.
Edge case: If you want to avoid prescription-only, Glutathione is the more accessible choice.
Default choice: Glutathione. Lower friction to source, and broader goal coverage. Reach for Clomiphene only if your priority sits squarely in the goals it owns above.

Which has a longer half-life, Clomiphene or Glutathione?
Clomiphene half-life is 168 hours; Glutathione half-life is 0.5 hours.
Can you stack Clomiphene with Glutathione?
Stack compatibility depends on mechanism overlap, legal status, and individual response. Check each compound page for specific interactions and contraindications before combining.
