The 6 Best Fertility Supplements to Help You Get Pregnant

6 min read

Whether you’re trying to conceive or are starting to think about it, chances are you’ve gone down the Google rabbit hole and found loads of overwhelming info. Though there’s lots to know about planning for pregnancy, it’s helpful to focus on the basics to start: make a few lifestyle changes, learn the basics of ovulation and timing if you’re trying via intercourse, and get your prenatal vitamin routine in check.


While a healthy diet can provide many helpful nutrients, taking targeted egg health supplements can enhance egg quality and keep your hormones running smoothly. Not sure what to take? Read on for the best prenatal supplements to help you get pregnant and support your fertility


The best fertility supplements for women trying to conceive include Folic Acid (400 to 1,000 mcg daily), Vitamin D, CoQ10 (200 to 600 mg), Omega-3 fatty acids (DHA/EPA), N-acetylcysteine (NAC), and melatonin. Together, these nutrients support egg quality, hormone regulation, and ovulationβ€”the core pillars of female reproductive health.
When should you start taking fertility supplements? Ideally, at least 3 months before trying to conceive. Eggs take about 90 days to mature, which means antioxidants like CoQ10 and NAC need that lead time to meaningfully improve egg quality before ovulation.


Those who tend to benefit most from targeted supplementation include people over 30, those with lower ovarian reserve, anyon dealing with male-factor infertility (especially low motility),and anyone preparing for IUI or IVFβ€”though a complete prenatal vitamin is a strong foundation for anyone trying to conceive or in thier reproductive era.

1. Folate

One of the first things any doctor will recommend is getting your daily recommended amount of Folic Acid (400 to 1,000 mcg), which can also be found in the bioavailable form of 5-methyltetrahydrafolate (5-MTHF). These are both forms of Folate, which is used to make our DNA and assist cell divisionβ€”an essential process for a developing embryo. Folates are also necessary to prevent defects during neural tube formation. This is critical for baby’s early brain and nervous system development.

2. Vitamin D

Known as the β€œsunshine” vitamin, Vitamin D is actually much more than a nutrient. It acts as a hormone with receptors located in almost every tissue in the body. You might know it for its role in preventing seasonal affective disorder (A.K.A. the β€œwinter blues”) and for supporting bone health, but this vitamin-hormone plays a special role in fertility, too.


Vitamin D assists with the development of ovarian follicles (that’s where eggs live before you ovulate) and may improve thickening of the uterine lining. Research has actually seen a seasonal change in pregnancy rates that correspond to when Vitamin D levels are the highest. And studies have found that having concentrations greater than 75 nmol/L led to more positive pregnancy tests and live births.


To reach adequate levels, guidelines recommend supplementing with 800 to 1000 IU daily while trying to conceive and during pregnancyβ€”though recent studies have shown even more (up to 2,500 IU) can be beneficial. (Read even more about the benefits of Vitamin D for fertility here.) Maternal Vitamin D status will also support baby's bone developmentβ€”our Calcium + Magnesium + Vitamin D Boost makes it easy to hit your daily target.

3. CoQ10

Coenzyme Q10 is an antioxidant and a key molecule in the pathway that pumps out cellular energy. Known as a β€œmitochondrial support” supplement, it helps ensure that your eggs are packed with enough energy to help the embryo survive and thrive after it’s been fertilized.

Our natural levels of CoQ10 decline around when we hit 30, so this supplement is key if you’re over that age or have lower ovarian reserve. Common and safe doses range from 100 to 600 mg per day. (P.S. Have a partner with sperm? CoQ10’s antioxidant actions can improve sperm concentration and health as well.)

4. Omega-3 Fatty Acids

Every cell in your body needs Omega-3 fatty acids, but most diets don't have enough and supplementing is keyβ€”especially when trying to conceive. This nutrient is critical to fetal brain, eye, and neurological development, brain function, blood pressure management, and works as an anti-inflammatory. (It's important for sperm health, tooβ€”when males don't get enough sperm motility can be affected.)

5. N-Acetyl Cystine (NAC)

NAC is a potent antioxidant that also promotes detoxification. It can protect eggs (and sperm!) from oxidative damage (havoc caused by environmental stressors and more). Meanwhile, its effects can also increase the quality of cervical mucus during the fertile window. This is important as cervical mucus helps the movement of sperm as they journey up towards the egg. It also helps maintain a proper environment for sperm survival. Daily doses that have been used in fertility studies range from 600 to 1,800 mg.

Supplements like CoQ10, NAC, and L-Carnitine are antioxidants that can protect your eggs from oxidative damage and provide cellular energy so they can mature.

6. Melatonin

This hormone does more than just keep you in a deep sleep cycle. Melatonin has major antioxidant effects and is found in the ovaries as a way of protecting your eggs. Its multiple actions include regulating the production of key hormones such as LH and FSH, overall improving egg development. Researchers have seen positive outcomes in IVF studies as well: Compared to no Melatonin treatment, those who supplemented with 3 mg before bed in an IVF cycle had a greater amount of high quality embryos, and increased pregnancy rates of 19.6% versus 10.2%.


With its anti-inflammatory and DNA-protecting effects, Melatonin supplementation may be well-suited for those trying to conceive in their thirties and beyond to enhance egg quality.


Note: While Melatonin is a powerful antioxidant and has benefits for both fertility and sleep, emerging research shows that overuse or long-term reliance on high doses can have its drawbacks. Make sure to speak to your healthcare provider.

What does NAC do for fertility?

NAC (N-acetylcysteine) is a potent antioxidant and precursor to glutathioneβ€”one of the body's most important protective compounds. It helps shield eggs from oxidative damage, supports healthy ovulation, and can improve cervical mucus quality during the fertile window, making it easier for sperm to reach the egg. For women with PMOS/PCOS, clinical studies show that NAC can improve both ovulation and pregnancy rates.

Should I take CoQ10 and NAC together for fertility?

Yesβ€”they complement each other well. CoQ10 fuels the mitochondrial energy that egg cells need to develop, while NAC works to reduce oxidative stress that can damage eggs over time. Together, they support two distinct pathways of egg quality. You'll find both in the Bird&Be Female Fertility Power Prenatal Pack, formulated at research-backed doses by fertility doctors.

What is the best dose of CoQ10 for fertility?

Most fertility studies use between 200 and 600 mg of CoQ10 daily. Research at the 600 mg dose has shown meaningful improvements in pregnancy rates in women undergoing IVF. As always, check with your healthcare provider on the right dose for you.

What supplements increase cervical mucus?

NAC, Omega-3 fatty acids, and Vitamin C are the most studied supplements for supporting fertile-quality cervical mucus. NAC in particular helps thin and loosen cervical fluid, which supports sperm motility on its journey to the egg.
