What Prenatals and Multivitamins Are Often Missing for Fertility
I hear this from couples all the time. She started her prenatal, he started a multivitamin, and they feel like they have checked the nutritional box. I understand why they think that. But in my experience, that is usually just the starting point, not the finish line.
Here is the reality I share with my patients. Most prenatals are designed to support pregnancy, not necessarily egg quality, sperm quality, inflammation, oxidative stress, insulin resistance, or embryo development. Those are very different goals, and the formulas reflect that difference.
Many prenatals are still missing meaningful amounts of:
- Choline
- Magnesium
- Omega-3s
- CoQ10
- Antioxidants
- Bioavailable folate
The same problem exists on the male side. A standard men’s multivitamin may support general health, but it is usually not designed to improve sperm motility, morphology, DNA integrity, or mitochondrial function. General health and reproductive health are not the same thing, and the supplements you take should reflect that distinction.
The Best Vitamins for Egg Quality and Female Fertility
For women, much of what I am trying to do nutritionally is improve the environment around the egg itself. The egg is not isolated from the body. It is profoundly influenced by inflammation, oxidative stress, mitochondrial function, and hormonal balance. When we address those factors, we give the egg a better chance.
The nutrients I look to for egg quality support include:
- CoQ10
- PQQ
- NAC
- Alpha-lipoic acid
- NMN
- Vitamin D
- Omega-3s
- Magnesium
- Methylated folate
- Selenium
- Zinc
- Choline
These nutrients work together to support ovulation, implantation, hormone balance, and embryo development. That is not a coincidence. These systems are connected, and the best nutritional strategies recognize that connection rather than treating each one in isolation.
The Best Vitamins for Sperm Quality and Male Fertility
I want to be direct about something that does not get enough attention. Male factor infertility plays a role in roughly half of all fertility challenges, and sperm quality affects far more than count alone.
Poor motility, abnormal morphology, oxidative stress, and high DNA fragmentation can affect fertilization, embryo quality, miscarriage risk, and IVF outcomes. I have seen couples spend months focused entirely on her health while the sperm picture goes unaddressed. Both partners matter equally in this process.
For men, the nutrients I pay attention to include:
- CoQ10
- L-carnitine
- NAC
- Zinc
- Selenium
- Omega-3s
- Vitamin C
- Vitamin E
- Methylated folate
This is precisely why Rejoova was built around separate, targeted formulas rather than a one-size-fits-all approach. Rejoova Eggs, Rejoova Sperm, and Rejoova Repair were designed to support both partners in a comprehensive and coordinated way, addressing the specific biological demands of egg quality, sperm health, and cellular repair as distinct priorities that deserve distinct solutions.
When both partners are supported properly and early enough, you give your fertility journey the strongest possible foundation. That matters whether you are trying naturally, preparing for IVF, or somewhere in between.
