Berberine vs Semaglutide: Which Is Better for Weight Loss?
No. Berberine scores 6.8 and semaglutide 6.0, and that gap misleads almost everyone who reads it. Berberine scores higher because it is cheap, oral and easy to stop,…

Metformin
The evidence supports a use-case score of 6.8/10 for Metformin in female fertility, based on the meta-analysis of 13 randomized trials that reported higher ovulation odds (Lord 2003). Metformin targets insulin resistance,…

Tirzepatide
Female fertility receives a 6.8/10 Tirzepatide score because weight loss and insulin improvement can indirectly help ovulatory function, especially in obesity-linked PCOS patterns Franco 2025. The limitation is direct evidence: fertility endpoints…

NAC (N-Acetylcysteine)
Female fertility scores 6.0/10 on PCOS ovulation-induction data. A meta-analysis of eight RCTs (n=910) by Thakker 2015 found NAC improved ovulation (pooled OR 3.13), pregnancy (OR 3.58), and live birth (OR 3.00)…

Berberine
Fertility Female is a 6.0/10 use case for Berberine, not a blanket claim. Female fertility relevance is mainly PCOS ovulation restoration through insulin sensitization. This score is capped by pregnancy avoidance requirements…

Semaglutide
Fertility-female scores 5.5/10 because weight loss and insulin improvement can support ovulation in PCOS or obesity-linked infertility, but Semaglutide must be stopped before conception. Moiz 2024 supports meaningful weight loss, which is…

High-Dose Melatonin
High-Dose Melatonin has female-fertility relevance, though much of the direct IVF evidence uses lower doses. The assisted-reproduction meta-analysis reported improved clinical pregnancy odds with melatonin among randomized trials (Hu et al. 2020).…

Kisspeptin-10
Female fertility is the best-validated use, again driven by kisspeptin-54 rather than kisspeptin-10. A single subcutaneous dose triggered egg maturation at every dose tested across 53 women in IVF, with embryo transfer…

Zone 2 Cardio
The practical fertility-female read on Zone 2 Cardio is 5.0/10 because Vabishchevich 2026 anchors the strongest signal. The existing rationale points to this narrower claim: Moderate aerobic training supports insulin sensitivity, body…

Essential Amino Acids
No direct female-fertility evidence was verified. Pregnancy and fertility claims should defer to standard prenatal nutrition guidance.

Glycine
No direct female-fertility RCT evidence for glycine supplementation.

Whole-Body Vibration
No direct female fertility evidence. Pregnancy is a contraindication, so fertility-adjacent claims need caution.

Coenzyme Q10 (CoQ10 / Ubiquinol)
Female fertility scores 4.5/10. CoQ10 is widely used in assisted reproduction for older women on the theory of supporting oocyte mitochondrial function, and small trials show improved ovarian response markers. But clean…

Ca-AKG (Calcium Alpha-Ketoglutarate)
No direct female-fertility evidence. Avoid in pregnancy and lactation because safety data are insufficient.
Read the Ca-AKG (Calcium Alpha-Ketoglutarate) report → -
Ashwagandha
Female sexual-function data is not the same as fertility evidence. V0 preserved a modest score because direct female fertility RCT evidence is thin, and pregnancy remains an avoidance context. Ashwagandha should not…

Ketogenic Diet
Female fertility response is bimodal. Mavropoulos 2005 supports pilot-level PCOS benefit through lower insulin and androgen markers. In lean eugonadal women, lower free sex hormones, T3 shifts, and amenorrhea risk can move…

Resveratrol
Female-fertility use is not clinically established. Resveratrol's phytoestrogen activity creates both theoretical upside and theoretical downside depending on tissue context, ovarian status, endometrial biology, and cancer risk. No robust human fertility RCT…

HRV Biofeedback
One small RCT in pregnant women; HPA modulation plausible. Pregnancy is documented safe context.

Astaxanthin
Maleki-Hajiagha 2024 and Rodrigues 2025 support selected ART lab endpoints, but not broad pregnancy-outcome certainty.

Tongkat Ali
Muniandy 2025 adds the first larger Physta menopause RCT signal for quality of life and sexual-domain improvement, but pregnancy and lactation remain excluded by EFSA 2021 and female fertility itself has not…

Omega-3
Female fertility evidence is limited. Pregnancy outcome evidence is stronger than pre-conception fertility evidence.
