When a couple is thinking about having a baby, actively trying to conceive, or persisting in their fertility journey, they all tend to focus on one thing — the baby. But before the baby, before the pregnancy, even before the conception, there’s another thing worth focusing on. It’s the critical period known as the preconception window, a four to six-month timeframe during which you can actively take steps to support your preconception health and even impact the health of your future children. So much of it comes down to a healthy lifestyle, including the right nutrients at the right time – and that’s where prenatal vitamins for men and women come in.
Supporting Egg & Sperm Quality
From a biological standpoint, nutrition and lifestyle changes during the preconception window are as critical as the conscientiousness we exhibit during a pregnancy itself. This is the time to prioritize your health by actively supporting egg and sperm health. And science is showing us how. In both women and men, key micronutrients have been linked to the very processes that drive our reproductive health.
Nutrients to Optimize Fertility Health in Women
While it’s true that a woman is born with all the eggs she’ll ever have, those eggs aren’t ready for fertilization without first undergoing a critical growth process that takes about three months – i.e. the preconception window. This egg maturation stage may be optimized when a woman is eating a varied, nutritious diet, filling any gaps with a high-quality prenatal vitamin, and generally leading a healthy lifestyle. The preconception window is a critical time to promote egg quality with nutrients proven to make a difference:
- Vitamin C: Low levels of ascorbic acid have been found in women who experience multiple miscarriages.
- Vitamins B6 and B12: B6 and B12 work together to regulate healthy hormone balance and trigger regular ovulation for a greater chance of conception. The right amount of B6 helps promote balanced levels of estrogen and progesterone, which is crucial for the cell signaling that happens during egg maturation and ovulation. B12 is necessary for cell division and building healthy blood.
- Vitamin D: Women with high levels of vitamin D show a four-fold increase in successfully achieving pregnancy. Other studies have found a link between high vitamin D levels and higher pregnancy rates. Vitamin D supplementation is also associated with an improvement in hormonal function among women with PCOS.
- Vitamin E: Vitamin E is known for its role in cellular repair, which is why it’s commonly found in skincare products. In the ovaries, E is a powerful antioxidant that can help defend against oxidative damage to eggs and prevent the most negative effects of premature aging.
- Zinc: Zinc is involved in multiple processes that regulate germ cell growth, fertility, and pregnancy.
- Vitamin K2: Vitamin K2 has an important relationship with women’s hormonal health, aiding in estrogen and progesterone metabolism. In a 2016 study, women with PCOS who took K2 supplements had lower levels of DHEA and free testosterone, which creates a greater opportunity for hormonal healing.
- Folate: Supplementing with a high-quality, bioavailable form of methylated folate has been shown to substantially lower the risk of chromosomal abnormalities. Adequate folate levels also help improve chances of conception.
- Chromium: This mineral may help improve fertility health in women with PCOS by reducing insulin and testosterone levels.
Nutrients to Optimize Fertility Health in Men
In men, supporting sperm health is likewise tied to specific nutrients. Men produce millions of sperm every day, but they also have a maturation process that takes about three months. To produce the healthy sperm, a steady stream of the right nutrients is important:
- CoQ10: An antioxidant known for its essential role in metabolic function, it’s been shown to increase sperm motility.
- Methylated folate: There is evidence that folate supplementation improves sperm count, morphology, and motility. One study also found low folate levels in semen is associated with a greater risk of sperm DNA damage.
- Vitamins C, E, B6 and B12: This group of antioxidants may help improve sperm quantity, motility, and morphology, as well as protect sperm from free radical damage.
- Vitamin D: Technically a hormone, vitamin D supplementation is linked to higher quality sperm, while low vitamin D levels are associated with poor sperm quality.
- L-Carnitine: This compound, which helps support metabolism, is associated with improved sperm quality.
- Selenium: This antioxidant has been shown to raise testosterone and improve multiple sperm parameters.
- N-acetyl-L-cystine (NAC): Studies show that supplementing with NAC significantly improves all semen parameters, particularly when combined with selenium.
- Zinc: Multiple studies show that zinc supplementation improves sperm motility, morphology, and volume. Plus, low zinc levels are common in men with infertility.
- L-Arginine: This amino acid plays a pivotal role in sperm production and has been shown to improve sperm quality.
- L-Taurine: Low levels of this antioxidant are associated with poor sperm parameters.
- Shilajit: This Ayurvedic adaptogen has been used for centuries for virility. It’s been shown to support sperm count, motility, and testosterone.
It Takes Two
For couples hoping to become parents, quality prenatal vitamins that deliver critical nutrients in adequate amounts to both partners are a great way to support the kind of optimal fertility health that may be hard to get from diet alone.
Both sperm and egg need healthy, well-nourished environments in which to thrive. That’s what makes the preconception period so important — it’s during this timeframe that epigenetic information about both parents’ health and lifestyle is passed onto potential future children through the maturing sperm and eggs.
In creating Beli Vitality for Men and Beli for Women, we referenced the latest in fertility nutrition. Our science-aligned formulas include all of the nutrients we’ve listed above, simply because they’ve been shown to promote and support critical factors in fertility health. Because just as it takes two to make a baby, it takes two to truly cover all those nutritional bases — two prenatal vitamins, that is.
