Fertility is a journey, and navigating the vast array of supplements available can be overwhelming. As a Fertility Dietitian in the UK, I often get asked about the best fertility supplements and prenatal vitamins. In this blog, I will provide evidence-based recommendations on the best fertility supplements in 2025 to help you make informed decisions. Let’s dive in!
The best prenatal vitamins
If you’re trying to conceive, a high-quality prenatal supplement is one of the best investments you can make. Prenatal supplements are multivitamins that contain essential nutrients to support fertility. We recommend starting a prenatal supplement three months before trying to conceive to enhance egg quality and fill any nutrient gaps.
Why take a prenatal supplement
Evidence shows that taking a prenatal supplement alongside a fertility-supporting diet can significantly boost your chances of conception. Here are some benefits:
- Reduce Nutrient Deficiencies: Prenatal supplements help cover any nutritional gaps, lowering levels of certain nutrients linked to unexplained infertility and increased time to pregnancy.
- Strengthen Antioxidant Defences: They protect eggs from damage.
- Reduce Ovulatory Problems: Ovulatory issues are a common cause of infertility, and supplements can help mitigate this.
- Support AMH Levels: Anti-Müllerian Hormone (AMH) levels, a marker of ovarian reserve, can be supported with the right nutrients.
How to choose the best prenatal fertility supplement for you
With many products on the market, it’s important to choose one that fits your needs. Here’s what to look for:
- Vitamin D: Lower levels are associated with infertility. Ensure your supplement contains at least 10mcg.
- Folate or Folic Acid: Critical for DNA production, egg quality, and implantation. Look for at least 400mcg.
- Antioxidants: Look for vitamins C, E, and selenium to combat oxidative stress.
- Zinc: Essential for the egg maturation process.
- Iodine: Important for thyroid function and reducing the risk of unexplained infertility.
- B Vitamins: Vitamins B12 and B6 are crucial, as insufficient levels are common in infertile women.

Methyl folate vs folic acid
Prenatal supplements may contain vitamin B9 in its natural form (methylfolate) or its synthetic form (folic acid). A risk factor for neural tube defects is having low folate levels. Both forms increase blood folate levels, which corrects the risk factor of folate deficiency, but currently, public health guidance recommends folic acid to reduce the risk of neural tube defects. If your prenatal supplement contains methylfolate, you can safely add 400 mcg of folic acid; always discuss with your healthcare provider or fertility expert beforehand.
Methylfolate may be considered in some situations, for example, people who carry a mutation in the MTHFR gene may not be able to convert folic acid to the active form of folate in the body as efficiently as those without the mutation. There is also some evidence to suggest that methylfolate could be explored in cases of recurrent miscarriage or recurrent implantation failure. However, you should discuss this with your healthcare provider. This information is not a substitute for individualised medical advice.

Our other top fertility supplement recommendations
For specific needs, other supplements might be beneficial. Here are our top recommendations to help you on your fertility journey.
The best CoQ10 supplements for fertility
If you are over the age of 35, adding a Coenzyme Q10 supplement to your regimen can be one of the best fertility supplement choices you can make. CoQ10 is crucial for energy production and can help support egg production, maturation, and quality.

MicroCell CoQ10 – A high-strength supplement delivering 200mg of ubiquinone, the standard form of CoQ10.
Fertility supplements for PCOS
For those with Polycystic Ovary Syndrome (PCOS), myoinositol can be particularly beneficial. It helps regulate menstrual cycles, restore ovulation, improve egg and embryo quality, and enhance clinical pregnancy rates. With regards to doses, 4g/day of myo-inositol alone or a combination of myo-inositol and d-chiro inositol in a 40:1 ratio can support outcomes.
This supplement has also been shown to increase clinical pregnancy rate in women undergoing IVF by improving egg and embryo quality and improving response to ovarian stimulation.
Here are our top recommendations for the best myoinositol for PCOS and to support IVF outcomes:

The best omega-3 supplements for fertility
Omega-3 fatty acids are essential fats that must be consumed through diet or supplements. They are beneficial for supporting ovarian reserve, egg quality, and improving IVF outcomes. Omega-3 supplements are particularly important if you do not consume 1-2 portions of oily fish weekly. Research indicates that even those who consume omega-3 through food can benefit from supplementation.
We recommended to consume around 500-1000mg per day. .
