Egg Freezing Supplements: 11 Things to Know About What Actually Works

The supplement industry around egg freezing is worth hundreds of millions annually, and largely unregulated. Here is the evidence-based version, without financial interest in what you buy. Before you spend £200 a month on a fertility supplement stack, here are 11 things to know. 11 Things to Know

1. CoQ10 (ubiquinol form) has the strongest evidence of any supplement for egg quality Multiple studies show improved fertilisation and embryo quality, particularly in older women and diminished reserve. What to do: Take ubiquinol at 400-600mg daily for at least 90 days before retrieval.

2. Vitamin D deficiency is associated with worse IVF outcomes — and most women in northern Europe are deficient Adequate vitamin D is linked to better follicular development and outcomes. What to do: Test your level first, then supplement 2,000-4,000 IU if deficient.

3. Myo-inositol has specific evidence for PCOS patients — less so for non-PCOS Inositol improves insulin sensitivity and LH profiles specifically in PCOS. What to do: Consider it at 2-4g daily only if you have PCOS.

4. DHEA has evidence specifically for diminished ovarian reserve — not for all women It can improve response in low-reserve patients but may harm those with normal/high reserve or PCOS. What to do: Only take DHEA under RE guidance based on your full hormonal profile.

5. Omega-3 fatty acids support anti-inflammatory conditions for follicle development Observational evidence links higher intake to better oocyte quality. What to do: Supplement 1-2g combined EPA/DHA if you don't eat oily fish twice weekly.

6. Folate (not just folic acid) is essential — and the form matters for some women MTHFR variants reduce conversion of folic acid to its active form. What to do: Consider methylfolate supplementation at 400-800mcg daily.

7. Melatonin has emerging evidence for egg quality — with a specific mechanism Melatonin acts as an antioxidant in follicular fluid, with promising evidence for poor responders. What to do: Consider 3mg nightly starting 6-8 weeks before retrieval if you're over 38 or had poor prior response.

8. Prenatal vitamins are a useful foundation — not a comprehensive supplement protocol A good prenatal covers folate, iron, iodine, vitamin D, and B vitamins but not CoQ10 or omega-3. What to do: Start a prenatal 90 days out, then layer evidence-based supplements on top.

9. Iron and ferritin levels deserve specific attention before egg freezing Subclinical iron deficiency is common and can worsen with the metabolic demands of a cycle. What to do: Request a ferritin test specifically and supplement if below 70 ng/mL.

10. Royal jelly, bee pollen, and most boutique fertility supplements have weak evidence Marketing for these products is significantly ahead of the science. What to do: Cover CoQ10, vitamin D, omega-3, and folate first before spending on anything else.

11. Your RE is the right person to design your supplement protocol — not a wellness influencer The right protocol depends heavily on age and clinical profile. What to do: Take this list to your RE and ask what they'd recommend and at what doses for you specifically. The egg freezing supplement space is full of expensive products with thin evidence. The supplements with real evidence are often the cheapest and least exciting ones. Flavia: Spend your money on CoQ10, vitamin D, omega-3s, and good food. Save the rest for the storage fees.
