Supplements for Low AMH: What the Evidence Actually Supports

💡 Quick Answer

The supplements with the strongest evidence for supporting low AMH are CoQ10 (200–600mg/day), DHEA (75mg/day under medical supervision), and vitamin D (if deficient). A 2025 meta-analysis of 2,773 women found these supplements significantly improved AMH levels, follicle counts, and pregnancy rates — with CoQ10 showing the greatest effect.

I built my supplement protocol out of desperation and research in equal measure. When my AMH came back at 3 pmol/L at 32 — roughly a quarter of what's expected — I wasn't willing to just accept "egg freezing is your only option" as the final answer. I spent months digging through studies, consulting with specialists, and testing on myself. Twelve months later, my AMH had climbed to 6.43 pmol/L and I was pregnant naturally.

I'm not telling you that story to promise the same outcome. I'm telling it because I know what it's like to sit with a devastating number and wonder "can I actually do anything about this?" The honest answer is: yes, some things help, but the evidence varies wildly between supplements, and plenty of what you'll find online is wishful thinking dressed up as science.

This article breaks down every supplement worth considering for low AMH — what the research actually says, what I took personally, and what I recommend to my clients. No miracle claims. Just evidence, experience, and honesty about where the gaps are.

Understanding What Supplements Can and Can't Do

Before we get into specific supplements, I need to be direct about the biology. You cannot create new eggs. You were born with every egg you'll ever have — somewhere between 1 and 2 million at birth, declining to roughly 300,000 by puberty. AMH reflects the number of developing follicles in your ovaries, which correlates (imperfectly) with your remaining egg supply.

So when I say a supplement "improved AMH" in a study, what that likely means is one of two things:

• It supported the health and development of existing follicles, making more of them detectable on the AMH assay. The follicles were there — they're just functioning better.
• It reduced factors that were suppressing AMH — like vitamin D deficiency, oxidative stress, or mitochondrial dysfunction — revealing your "true" AMH level rather than genuinely increasing it.

Either way, the practical outcome is the same: better ovarian function, more usable follicles, and (in some studies) higher pregnancy rates. That matters — even if the biological mechanism is more nuanced than "growing new eggs."

CoQ10: The Strongest Evidence for Egg Quality

If I could only recommend one supplement for low AMH, it would be Coenzyme Q10. The evidence is the most consistent, the mechanism is well understood, and the safety profile is excellent.

What the Research Shows

CoQ10 is a naturally occurring antioxidant that lives inside your mitochondria — the energy factories in every cell, including your eggs. As you age, mitochondrial function declines, and this is a major driver of reduced egg quality (Ben-Meir et al., 2015, Aging Cell).

The landmark 2015 mouse study by Ben-Meir at the University of Toronto demonstrated that CoQ10 supplementation restored oocyte mitochondrial function and reversed age-related fertility decline. In human studies, CoQ10 has been shown to:

• Improve oocyte quality and embryo grades in IVF patients with diminished ovarian reserve (Xu et al., 2018)
• Increase the number of retrieved oocytes in women with poor ovarian response (Bentov et al., 2014)
• Raise AMH levels when combined with other supplements — the 2025 meta-analysis by Li et al. (Journal of Reproductive Immunology) found CoQ10 alone was more effective than DHEA alone at improving AMH and follicle counts across 16 studies of 2,773 women

How I Use It

I took 200mg of ubiquinol (the active form of CoQ10) daily throughout my fertility journey. Most studies use doses between 200–600mg/day. I recommend starting at 200mg and increasing to 400mg if you're over 35 or have very low AMH. Ubiquinol is better absorbed than ubiquinone — it costs more, but your body doesn't have to convert it.

Take it with a meal containing fat — CoQ10 is fat-soluble and absorption increases significantly when taken with food. I'd take mine with breakfast alongside avocado or olive oil.

📋 CoQ10 Summary

Form: Ubiquinol (preferred) or ubiquinone
Dose: 200–600mg/day
Evidence strength: Strong (multiple RCTs, meta-analysis)
Best for: Egg quality, mitochondrial function
Timeline: Minimum 3 months (one full egg development cycle)
Side effects: Rare; mild digestive upset at high doses

DHEA: The Most Studied for AMH Improvement

Dehydroepiandrosterone (DHEA) is a steroid hormone naturally produced by your adrenal glands and ovaries. It's a precursor to testosterone and oestrogen — both of which are involved in follicle development. DHEA is the supplement with the most direct evidence for raising AMH levels, but it comes with important caveats.

What the Research Shows

A 2024 meta-analysis in Fertility and Sterility reviewed six randomised controlled trials of DHEA in women with diminished ovarian reserve. The findings:

• DHEA supplementation (75mg/day) significantly improved the number of oocytes retrieved during IVF
• Multiple studies reported AMH increases of 0.5–1.5 ng/mL over 2–4 months of supplementation
• A 2024 clinical study of 122 women with DOR found DHEA improved AMH levels, AFC, and FSH after 12 weeks (Al-Noor University, Steroids)

The 2025 meta-analysis confirmed that supplementation for more than 2 months showed better results than shorter courses — so consistency matters.

The Caveats

DHEA is a hormone, not just a vitamin. It can:

• Cause acne, oily skin, and hair growth (androgenic side effects)
• Worsen PCOS symptoms in women with already-elevated androgens
• Interact with hormonal medications

DHEA must be taken under medical supervision. I cannot stress this enough. It's available over the counter in the US but prescription-only in the UK and many other countries — and there's a reason for that. Have your DHEA-S and testosterone levels checked before starting, and monitor them during supplementation.

I didn't take DHEA myself because my androgens were already within range and I was focused on a food-first approach. But I've had clients whose AMH responded significantly to supervised DHEA — particularly those with very low androgens alongside low AMH.

📋 DHEA Summary

Form: Micronised DHEA capsules
Dose: 75mg/day (typically 25mg three times daily)
Evidence strength: Strong (6+ RCTs, meta-analyses)
Best for: AMH improvement, follicle count, IVF response
Timeline: 2–4 months minimum
Side effects: Acne, oily skin, hair growth. Contraindicated in PCOS with high androgens
⚠️ Requires medical supervision

Vitamin D: The Deficiency You Probably Don't Know About

Vitamin D is less glamorous than CoQ10 or DHEA, but correcting a deficiency may be the single most impactful thing you can do — because vitamin D deficiency is staggeringly common and directly linked to lower AMH.

What the Research Shows

Dennis et al. (2012) demonstrated a significant positive correlation between vitamin D levels and AMH in both men and women. Women who are vitamin D deficient consistently show lower AMH than women with sufficient levels — and crucially, correcting the deficiency often reveals a higher "true" AMH.

A 2017 study in Journal of Clinical Endocrinology & Metabolism found that vitamin D supplementation increased AMH by an average of 14% in deficient women within 3 months. That's not a dramatic change, but when your AMH is borderline, a 14% increase could shift your clinical categorisation.

In the UK, an estimated 1 in 5 people have low vitamin D levels, rising to 1 in 3 during winter months (Public Health England). If you haven't had your vitamin D checked, get it tested alongside your AMH. It's a simple blood test and most GPs will do it readily.

How I Use It

I took — and still take — 10mcg (400 IU) of vitamin D3 daily as a baseline, increasing to 25mcg (1,000 IU) during winter. If you're clinically deficient (below 25 nmol/L), your doctor may prescribe a loading dose of 3,000–4,000 IU daily for 8–12 weeks before reducing to a maintenance dose.

Vitamin D is fat-soluble, so take it with food. I pair mine with my CoQ10 at breakfast.

📋 Vitamin D Summary

Form: Vitamin D3 (cholecalciferol)
Dose: 10–25mcg (400–1,000 IU) daily; higher if deficient
Evidence strength: Moderate-strong (correlation studies, some interventional)
Best for: Unmasking suppressed AMH, general reproductive health
Timeline: 3 months to correct deficiency
Side effects: Very rare at recommended doses. Don't exceed 4,000 IU without medical guidance

Omega-3 Fatty Acids: Supporting the Environment

Omega-3s (EPA and DHA) aren't going to raise your AMH number dramatically, but they create a better environment for everything else to work. Think of them as the foundation your protocol is built on.

A 2022 study in Aging followed women consuming higher levels of marine omega-3s and found they had significantly longer reproductive lifespans — later onset of menopause and slower decline in ovarian reserve markers. Omega-3s reduce systemic inflammation, improve blood flow to the ovaries, and support cell membrane integrity in developing eggs.

I took 1,000mg of combined EPA/DHA daily from a high-quality fish oil. If you're vegetarian, algae-based DHA supplements are a good alternative. The key is consistency — omega-3s accumulate in cell membranes over weeks, not days.

Melatonin: A Surprising Fertility Ally

Most people know melatonin as a sleep hormone. Fewer know it's also one of the most potent antioxidants in your ovarian follicular fluid — the liquid surrounding your developing eggs.

A 2012 randomised trial by Tamura et al. in the Journal of Pineal Research found that 3mg of melatonin nightly improved oocyte quality and fertilisation rates in IVF patients. More recent evidence suggests melatonin may protect follicles from oxidative damage, which is particularly relevant if you're over 35 or have evidence of diminished ovarian reserve.

The evidence for melatonin directly raising AMH is weaker than for CoQ10 or DHEA. But as an egg-quality protector, it's worth considering — especially if you also struggle with sleep, which is independently linked to reproductive hormone disruption.

I took 3mg of melatonin before bed during the months I was actively trying to conceive. One of my clients who was preparing for IVF with low AMH added melatonin to her protocol, and her embryo quality improved noticeably in her second cycle compared to her first — though we can't attribute that solely to melatonin since she'd changed several things.

📋 Melatonin Summary

Form: Melatonin tablets
Dose: 3mg nightly, 30 minutes before bed
Evidence strength: Moderate (RCTs for oocyte quality; limited for AMH specifically)
Best for: Egg quality, antioxidant protection, sleep support
Timeline: 1–3 months
Side effects: Drowsiness, vivid dreams. Prescription-only in the UK

My Complete Low AMH Supplement Protocol

Here's exactly what I took during my fertility journey, alongside my dietary and lifestyle changes. This isn't a prescription — it's transparency about what worked for me. Work with your healthcare provider to find what's right for your situation.

Alongside supplements, I overhauled my diet to Mediterranean-style (the most studied dietary pattern for fertility), switched to gentle exercise (stopped HIIT entirely), cut alcohol completely, went organic where possible, prioritised 8 hours of sleep, and added weekly fertility acupuncture and yoga.

Did every element contribute? Honestly, I don't know. But the combination moved my AMH from 3 to 6.43 pmol/L over 12 months, and I conceived naturally. I recommend a similar whole-protocol approach to my clients rather than relying on any single supplement.

🍎 Go Organic With the Dirty Dozen

These twelve fruits and vegetables carry the heaviest pesticide loads. I tell all my clients: if you can only afford to go organic on some things, make it these. The rest you can buy conventional and wash well.

The list: Strawberries, spinach, kale/collard/mustard greens, peaches, pears, nectarines, apples, grapes, bell & hot peppers, cherries, blueberries, green beans (EWG, 2025).

Supplements I Don't Recommend (or Can't Yet)

Not everything marketed for fertility has evidence behind it. A few popular options that I'm cautious about:

• Myo-inositol for low AMH specifically — strong evidence for PCOS and insulin resistance, but limited data for low AMH without PCOS. I recommend it to my PCOS clients but not routinely for diminished ovarian reserve.
• Royal jelly — a few small studies show promise, but nothing robust enough to recommend confidently. The quality control in royal jelly supplements is also inconsistent.
• PQQ (pyrroloquinoline quinone) — interesting emerging research on mitochondrial biogenesis, but human fertility data is almost non-existent. Watch this space, but don't spend money on it yet.
• High-dose antioxidant cocktails — more isn't always better. Excessive antioxidant supplementation can actually impair normal cellular signalling. Stick to evidence-based doses.

How Long Does It Take to See Results?

This is where patience matters — and where I see a lot of people give up too early.

Egg development takes approximately 90 days from the time a dormant follicle is recruited to the point of ovulation. That means any supplement you start today won't influence the eggs you're ovulating for another 3 months. The 2025 meta-analysis specifically found that supplementation for more than 2 months showed significantly better results than shorter courses.

My recommendation: give your protocol a minimum of 3 months before retesting AMH. Ideally, 6 months. And don't test every month — AMH naturally fluctuates by 10–20% between cycles, which can create false hope or unnecessary anxiety if you're testing too frequently.

I gave myself a full year. Not because I'm patient by nature — I'm really not — but because I knew the egg development timeline and I wanted to give every follicle the best possible chance. That patience was the hardest part of the whole journey, and also the most important.

🌿 Dani recommends:

I often make this antioxidant matcha latte as part of my morning ritual. Matcha is packed with EGCG, a powerful antioxidant that helps protect cells from oxidative stress — something that matters for egg quality as we age. Whisk 1 teaspoon of ceremonial grade matcha with 60ml hot water (not boiling), then add 200ml warmed oat milk and a drizzle of honey. The L-theanine gives you calm focus without the jitters of coffee. It's my go-to when I want something warm and nourishing that also supports my fertility goals.

The Bottom Line

The supplements with the strongest evidence for supporting low AMH are CoQ10, DHEA (under supervision), and vitamin D. A 2025 meta-analysis of 2,773 women confirmed that these supplements significantly improve AMH levels, follicle counts, and pregnancy rates — with CoQ10 showing the greatest individual effect. Omega-3s and melatonin play supporting roles in egg quality and ovarian health.

But supplements are one piece of a larger picture. Diet, exercise, stress management, sleep, and environmental exposures all matter. I didn't just take pills and hope — I rebuilt my entire approach to health, and the supplements were part of that, not the whole of it.

If you've been diagnosed with low AMH, you have more options than you've probably been told. Start with CoQ10 and vitamin D (both are safe, well-studied, and available without prescription). Talk to your doctor about DHEA if appropriate. Give yourself at least 12 months of preparation. And remember: AMH measures quantity, not quality. You don't need thousands of eggs — you need one good one.

▸What are the best supplements for low AMH?

The supplements with the strongest evidence are CoQ10 (200–600mg/day for egg quality and mitochondrial function), DHEA (75mg/day for AMH improvement, under medical supervision only), and vitamin D (to correct common deficiencies that suppress AMH). A 2025 meta-analysis of 2,773 women confirmed all three significantly improved fertility markers in women with diminished ovarian reserve.

▸Can CoQ10 improve low AMH?

CoQ10 primarily supports egg quality through improved mitochondrial function rather than directly raising AMH. However, the 2025 meta-analysis found CoQ10 alone was more effective than DHEA alone at improving AMH, follicle counts, and oocyte retrieval numbers. Most studies use 200–600mg/day of ubiquinol for at least 3 months.

▸Is DHEA safe for low AMH?

DHEA can be effective but must be taken under medical supervision. The standard dose is 75mg/day (25mg three times daily). Side effects include acne, oily skin, and increased body hair. It's contraindicated in women with PCOS who already have elevated androgens. Always have your DHEA-S and testosterone levels tested before starting.

▸Does vitamin D affect AMH levels?

Yes. Research shows a significant positive correlation between vitamin D levels and AMH. Women who are vitamin D deficient often show lower AMH, and correcting the deficiency can increase AMH by an average of 14% within 3 months. An estimated 1 in 5 people in the UK are vitamin D deficient, so it's worth testing.

▸How long do supplements take to improve low AMH?

Egg development takes approximately 90 days, so allow a minimum of 3 months before retesting AMH. The 2025 meta-analysis found supplementation for more than 2 months showed significantly better results than shorter courses. I recommend giving your protocol 6–12 months and not retesting AMH too frequently (every 3–6 months is sufficient).

▸Can you get pregnant naturally with low AMH?

Yes. Low AMH indicates fewer remaining eggs, not poor egg quality. A 2017 JAMA study of 750 women found no significant difference in natural conception rates between women with low AMH and normal AMH. Supplements, diet, and lifestyle changes can support egg quality and ovarian function, improving your chances even with low AMH.
