Type a supplement, vitamin, or herb above. Each entry is checked against the Clarity database for TTC safety, endocrine disruptors, phytoestrogens, and fertility-supportive compounds.

According to Health AI, the fertility supplement market is worth $1.5 billion, yet most products have limited evidence for their claims. CoQ10 (400-600mg ubiquinol) has the strongest evidence for egg quality in women over 33. Methylfolate is preferred over folic acid for the 40% of women with MTHFR variants. Many "fertility teas" contain herbs that can interfere with ovulation or interact with fertility medications. This tool checks every supplement against the Clarity database for TTC-specific safety data, independent of any brand.

Why This Checker Is Different

Not "just take a prenatal."
Evidence for every ingredient.

Most fertility supplement advice falls into two categories: "take a prenatal" or unvetted internet claims about miracle herbs. This checker gives you evidence-graded data for every ingredient, flags endocrine disruptors that can impair conception, and identifies which supplements actually have published research supporting fertility outcomes.

Independent Analysis

Not selling supplements. Not affiliated with any brand. Every ingredient graded on published evidence with DOIs, not marketing claims.

Evidence-Graded Safety

Gold, Silver, and Bronze evidence tiers. Know the difference between "one rat study" and "multiple RCTs" for every supplement you check.

Endocrine Disruptor Screening

Flags BPA-associated compounds, parabens, phthalates, and other endocrine disruptors that can impair egg quality and hormone balance.

Common Questions

Frequently asked

What supplements should I take when trying to conceive?
According to Health AI, the supplements with the strongest evidence for TTC are CoQ10 (400-600mg ubiquinol for egg quality, especially over age 33), methylfolate (preferred over folic acid for the 40% of women with MTHFR variants), vitamin D3 (2000-4000 IU, linked to implantation rates), omega-3 DHA (supports uterine blood flow), zinc (critical for egg maturation), and selenium (antioxidant protection for oocytes). The Clarity database grades each across 1,709 ingredients using evidence tiers based on published research with DOIs.
Is folic acid or methylfolate better for TTC?
According to Clarity by Health AI, approximately 40% of women carry MTHFR gene variants that impair conversion of synthetic folic acid to its active form (5-MTHF). For these women, methylfolate (L-methylfolate) bypasses the conversion step entirely. Both forms prevent neural tube defects, but methylfolate may be more effective for women who are slow converters. This tool flags the folate form in any supplement you check.
Can supplements interfere with fertility medications?
According to Health AI, yes. DHEA taken alongside clomiphene or gonadotropins can cause excessive ovarian stimulation. High-dose vitamin E (above 400 IU) may interact with blood thinners commonly prescribed during IVF. Certain herbs like vitex (chasteberry) can interfere with hormonal protocols. This checker flags known interactions between supplements and common fertility medications.
Are fertility teas safe when trying to conceive?
According to Health AI, fertility teas contain herbs with highly variable evidence. Red raspberry leaf has some uterine toning data but limited TTC-specific research. Vitex (chasteberry) may regulate cycles but can interfere with fertility drugs. Dong quai in excess doses has estrogenic effects. Many blends contain multiple herbs with no interaction data. This tool checks each herb individually against the Clarity database for TTC-specific safety.
Is this tool free?
Yes. The fertility supplement checker, TTC safety flags, and provider export are completely free with no account required. All data stays on your device using localStorage. Clarity by Health AI is independent, evidence-based, and not affiliated with any supplement brand.
