1. CoQ10 — Best for Egg Quality
Why: Eggs require enormous energy. CoQ10 supports mitochondrial ATP production in ovarian follicles.
Clinical Evidence:
- Bentov et al. (2014): 600mg/day for 2 months improved ovarian response in IVF patients.
- Xu et al. (2018): Improved ovarian response and embryo quality.
Effective Dose: 200-600mg/day (ubiquinol)
2. Inositol — Best for PCOS
Why: Improves insulin signaling, reduces ovarian androgen production, supports ovulation.
Clinical Evidence:
- Nestler et al. (1999): 1,200mg/day improved ovulatory function.
- Unfer et al. (2012): Meta-analysis confirmed improved ovulation rates.
Effective Dose: 4,000mg myo-inositol + 100mg D-chiro-inositol
3. NAC — Best Antioxidant
Why: Boosts glutathione, reduces oxidative stress in ovarian tissue.
Clinical Evidence:
- Porpora et al. (2013): Reduced endometrioma size and pain.
- Amini et al. (2020): Improved oxidative stress markers.
Effective Dose: 600-1,800mg/day
4. DIM — Best for Estrogen Metabolism
Why: Promotes healthy estrogen metabolism, reducing estrogen-driven ovarian conditions.
Effective Dose: 100-200mg/day
5. Omega-3 — Best Anti-Inflammatory
Why: Reduces ovarian inflammation and supports hormone production.
Effective Dose: 1,000-2,000mg EPA/DHA
6. Vitamin D3 — Essential
Why: Vitamin D receptors are present in ovarian tissue. Deficiency is associated with PCOS and reduced fertility.
Clinical Evidence:
- Wehr et al. (2011): Improved menstrual regularity and metabolic markers in PCOS.
Effective Dose: 4,000-5,000 IU/day
