The most important supplement for egg quality — especially over 35
CoQ10 (as ubiquinol) is the single most evidence-backed supplement for improving egg quality. Egg cells require more mitochondrial energy than any other cell in the body to mature, be fertilized, and support the first cell divisions of the embryo. CoQ10 directly fuels this mitochondrial energy production and protects egg DNA from oxidative damage. As CoQ10 levels naturally decline with age, supplementation is particularly important for women over 35 trying to conceive.
Women trying to conceive, especially those over 35, those with unexplained infertility, or those who have had IVF cycles with poor egg quality.
400–600 mg ubiquinol daily (choose ubiquinol, not ubiquinone — it's the active, pre-converted form). Take with a fat-containing meal. Start at least 3 months before trying to conceive.
Egg quality improvements require 3 months minimum — one full egg maturation cycle.
Generally very well tolerated. Mild digestive discomfort in a small percentage. May slightly lower blood pressure.
Stop when pregnancy is confirmed — not enough safety data for use during pregnancy. Avoid if taking blood thinners.
