Head-to-head evidence comparison — which supplement is right for you?
HCG (Human Chorionic Gonadotropin) vs Methylfolate: Methylfolate has the stronger overall evidence (6 vs 5.5/10); they're alternatives for fertility support — the best pick depends on your goals. Take the 60-second quiz for a pick tailored to your goals.
Methylfolate wins 2 of 3 categories. Both are solid choices — the best pick depends on your specific goals.

Prescription-only and indication-dependent. For fertility preservation / intratesticular-testosterone maintenance on TRT, the cited studies used 125-500 IU every other day (intramuscular in the one that states the route). For spermatogenesis induction in hypogonadotropic hypogonadism, typically ~1,000-2,500 IU two to three times weekly (often combined with FSH), titrated to response. For female ovulation/oocyte-maturation trigger, a single dose (~5,000-10,000 IU urinary or 250 µg recombinant). No cited study gives these two doses. No dietary-supplement dose exists.

Low-dose human chorionic gonadotropin maintains intratesticular testosterone in normal men with testosterone-induced gonadotropin suppression.
J Clin Endocrinol Metab (2005) · Rct · n=29
29 men with normal reproductive physiology randomized to weekly testosterone enanthate plus saline placebo or 125, 250, or 500 IU hCG every other day for 3 weeks
Concomitant intramuscular human chorionic gonadotropin preserves spermatogenesis in men undergoing testosterone replacement therapy.
J Urol (2013) · Observational · n=26
Retrospective cohort of 26 hypogonadal men on testosterone replacement plus 500 IU intramuscular hCG every other day, mean follow-up 6.2 months
A combined analysis of data to identify predictive factors for spermatogenesis in men with hypogonadotropic hypogonadism treated with recombinant human follicle-stimulating hormone and human chorionic gonadotropin.
Fertil Steril (2009) · Observational · n=100

Efficacy of B-vitamins and vitamin D therapy in improving depressive and anxiety disorders: a systematic review of randomized controlled trials
Nutritional neuroscience (2023) · Systematic review · n=2256
20 RCTs with 2,256 subjects with depression or anxiety, covering several B vitamins and vitamin D, not methylfolate alone.
Systematic Review and Meta-Analysis of L-Methylfolate Augmentation in Depressive Disorders
Pharmacopsychiatry (2022) · Meta analysis · n=6707
Nine articles (N=6,707 patients) were assessed qualitatively. The pooled analyses were smaller: three studies (N=483) and four studies (N=507).
Folic acid/methylfolate for the treatment of psychopathology in schizophrenia: a systematic review and meta-analysis
Psychopharmacology (2018) · Meta analysis · n=925
Ten RCTs with 925 patients were reviewed, of which two tested methylfolate (n = 96). Seven RCTs entered the meta-analysis.
Two randomised trials in people whose depression had not responded to an SSRI (PMID 23212058). In the first (148 patients), L-methylfolate at 7.5 mg a day for 30 days, then 15 mg, did no better than placebo. In the second (75 patients), 15 mg a day throughout beat placebo on response and symptom scores, with side effects no different from placebo. A meta-analysis found benefit only for methylfolate at 15 mg once daily added to an SSRI, with all evidence rated low or very low quality (PMID 29442609). The 800 mcg point comes from an open-label, non-randomised trial of 44 patients where adding methylfolate to an antidepressant improved PHQ-9 scores more by day 28 (40% vs 26%), but remission did not differ (PMID 39844190). No trial compared doses head to head, so no minimum or optimal dose is set.
AI-estimated from published studies. Interpret as directional guidance.
Methylfolate has a higher evidence score (6/10 vs 5.5/10) and wins in 2 of 3 categories.
For fertility support, Methylfolate has a higher relevance score (95 vs 62).
