Egg quality gets mentioned in almost every fertility appointment, but it is rarely explained in any meaningful way. Women walk out knowing their egg quality is a concern without understanding what that actually means or what they can do about it. Let me change that.
What Egg Quality Actually Is
Egg quality refers primarily to two things: chromosomal integrity and mitochondrial function. A high-quality egg has the correct number of chromosomes and enough mitochondrial energy to support fertilization, cell division, and early embryo development. When egg quality is poor, the embryo may arrest early, fail to implant, or result in an early miscarriage.
Egg quality cannot be seen on an ultrasound or measured by a blood test. It reveals itself through what happens after fertilization. But the cellular environment that shapes egg quality, which is being actively built for the 90 days before ovulation, is absolutely within your influence.
The 90-Day Window
A follicle takes approximately 90 days to mature from a resting state to a released egg. This is your window of influence. What you eat, how you sleep, how much oxidative stress your body is carrying, and how well your mitochondria are functioning all shape the cellular quality of the egg that matures during that time.
Oxidative stress is the primary driver of poor egg quality. Free radicals damage the DNA and mitochondria inside developing eggs. Antioxidants neutralize those free radicals. This is why antioxidant-rich nutrition and specific supplements like CoQ10 and vitamin E are not optional add-ons. They are protective interventions with direct mechanisms of action.
How to Start Improving Egg Quality Today
CoQ10 in the ubiquinone (as in Rejoova Eggs) form supports mitochondrial energy production inside maturing eggs. Omega-3 fatty acids reduce inflammation and protect cell membranes. Vitamin D supports follicle development and immune regulation. Methylfolate drives the DNA replication processes needed for chromosomally normal eggs.
Remove refined sugar, which drives insulin resistance and systemic inflammation. Prioritize sleep, because melatonin, produced during sleep, acts as a direct antioxidant in ovarian follicular fluid. Reduce endocrine-disrupting chemical exposure from plastics and conventional personal care.
Start now. The egg you ovulate in three months is being shaped by what you do today.
