Best Supplements for Egg Quality Over 40: Science-Based Fertility Support
·24 mins
After age 35, and especially after 40, female fertility declines sharply due to decreasing egg quantity (ovarian reserve) and declining egg quality. While you cannot increase the number of eggs remaining in your ovaries, you can meaningfully improve the quality of the eggs you do have—their mitochondrial function, DNA integrity, antioxidant protection, and fertilization competence. This is where targeted supplementation makes a measurable difference.
Egg quality determines whether an egg fertilizes successfully, develops into a healthy embryo, implants properly, and results in a viable pregnancy. Age-related decline in egg quality accounts for most fertility loss after 40, not ovarian reserve alone. Women with only a few remaining eggs can still conceive if those eggs are of good quality, while women with many eggs of poor quality face recurrent miscarriage and failed IVF cycles.
