Ever feel like your eggs always get the blame?

From unexplained infertility to poor fertilisation in IVF, it so often comes back to one thing: egg quality. And if you’re over 35, the pressure can feel even heavier.

Let me be clear—your eggs have a huge job:

• They must mature properly
• Be fertilised by sperm
• Help create a healthy embryo
• And yes, even correct damaged DNA from poor-quality sperm

It’s a lot. But here’s the good news: egg quality isn’t fixed, even if you’re over 35. With the right support – including targeted supplements – you can improve your chances of a successful pregnancy.

Let’s dive into what actually works.

What Happens to Egg Quality After 35?

There’s nothing magical (or tragic) about turning 35. Your egg quality doesn’t fall off a cliff at midnight on your birthday.

But here’s the truth: as we age, our eggs lose energy. That energy (produced by mitochondria) is what helps them divide properly and pass on the right genetic material.

When eggs struggle with this process, the chance of genetic errors increases. This can lead to failed fertilisation, miscarriage, or chromosomal abnormalities.

Whether you’re trying naturally or doing IVF, egg quality after 35 matters – but it’s not the only factor.

And it’s not all on you.

Why Egg Quality Gets Blamed (and What’s Often Missed)

Let’s not forget: having a baby is a team sport.

Sperm quality plays a huge role too. But often, poor embryo development or failed implantation is pinned solely on the egg.

The reality? It’s usually a combination of both egg and sperm factors.

That’s why improving egg quality matters even more when sperm quality isn’t ideal. Stronger eggs are better at correcting errors, leading to better fertilisation and healthier embryos.

Can You Really Improve Egg Quality After 35?

Yes – with realistic expectations.

If your egg quality is declining due to age, supplements can’t reverse time. But they can boost mitochondrial function, reduce oxidative stress, and support your body in producing the best eggs possible.

I’ve seen it over and over in clinic: a 10–15% improvement in egg quality can lead to a 100% real baby.

It’s not hype. It’s science – and strategy.

4 Key Supplements to Improve Egg Quality Over 35

Here are four of my favourite, science-backed supplements that specifically support egg quality after 35.

Take these for at least 90 days before trying to conceive, since egg development begins around 3 months before ovulation.

1. CoQ10 (Ubiquinol form)

• Why it works: CoQ10 supports mitochondrial energy production inside the egg—vital for healthy cell division.
• Best form: Ubiquinol (the active, bioavailable form).
  

2. Nicotinamide Riboside (NR)

• Also known as: NMN or NAD+ precursors.
• Why it works: Boosts mitochondrial repair and supports DNA integrity inside eggs.
  

3. Omega-3 Fatty Acids

• Why it works: Reduces inflammation and supports hormone balance and egg membrane structure.
• Look for: A high-quality fish oil.
  

4. Vitamin E (Mixed Tocopherols)

• Why it works: This antioxidant supports egg quality by protecting cells from oxidative stress and supporting hormone health. It’s a gentle yet powerful option that’s safe for most people trying to conceive.
  

💡 A quick note: Always check with your practitioner before starting a new supplement regime. More isn’t always better, quality matters more than quantity.

The 90-Day Egg Quality Timeline

Here’s where many people go wrong: they start supplements one month before IVF or egg freezing and expect miracles.

But egg development takes about 90 days, so what you’re doing today impacts the eggs you’ll ovulate 3 months from now.

This is your window to:

• Get targeted with egg quality supplements
• Improve your diet, sleep, and stress
• Reduce exposure to toxins and hormone disruptors

 

The Supplement Mistake I See All the Time

Here’s the secret most people miss (and it breaks my heart):

They’re taking the right supplements… but not enough to make a difference.

The dosage is too low. The quality is poor. Or they’ve bought five different brands without knowing which one actually helps.

If you’re going to invest in supplements, make sure they’re therapeutic grade and clinically dosed.

This is where personalised advice pays off.

One last thing…

While these supplements can support better egg quality, they’re not magic pills. True change happens when you combine them with lifestyle shifts like:

• Balanced nutrition (aka your egg quality diet)
• Managing stress and improving sleep
• Supporting blood sugar and hormone balance
• Cutting out smoking, vaping, and excess alcohol
• Reducing your exposure to environmental toxins

Egg quality is influenced by everything around it.

Supplements give your body a boost but they work best in the right environment.
