Egg freezing is unusual in the fertility world: it is one of the few steps you get to schedule. You pick the month, you know roughly when stimulation starts, and that means the weeks beforehand are yours to prepare in. The question we get is simple — what should I be taking during those weeks? Here is an honest answer, including what supplements cannot do.

The honest part first: no supplement changes how many eggs you retrieve
How many eggs a cycle yields is driven by things a capsule does not touch: your age, your ovarian reserve markers such as AMH and antral follicle count, your FSH, the protocol your clinic chooses and how your ovaries respond to the medication. No dietary supplement — ours included — can change your reserve, create new eggs, or make a retrieval produce more of them. Anyone telling you otherwise is selling you something.
What AGO products are designed to do is narrower and more ordinary: support everyday reproductive and cycle wellness during the months leading up to a cycle, alongside whatever your clinic has planned. That is the claim, and we would rather you hear it plainly than be sold a promise the science does not support.
Why the 90 days before your cycle is the window people talk about
The eggs recruited in any given cycle have been maturing for roughly three months beforehand. That long runway is why fertility teams talk about a 90-day preconception window and why they ask about diet, sleep, alcohol and smoking at the first appointment — the everyday inputs during that stretch are the ones that reach the cycle you are about to do.
Practically, that means the useful time to build a routine is now, not the week stimulation starts. If your cycle is eight weeks out, you still have most of a window. If it is next month, start anyway — just start with realistic expectations. More on the science of that window in CoQ10 and egg quality and supporting egg quality before IVF or IUI.
The unglamorous things belong here too: consistent sleep, sensible caffeine and alcohol habits, and knowing your own cycle pattern before a clinic starts mapping it for you.

The AGO combo most people choose before an egg-freezing cycle
For someone freezing eggs, the core pairing is the same one we suggest for the preconception window generally:
- AGO Mom — the base of the plan, designed to support everyday egg-cell and reproductive wellness through the 90-day window.
- AGO Eva — added for everyday hormonal and cycle wellness in the lead-up. How the two differ: AGO Mom vs AGO Eva.
- If you have PCOS or irregular cycles: many people add Eva Herblux — see also the PCOS + low AMH combo. Tell your clinic, because PCOS changes the protocol and the OHSS conversation.
- If you have fibroids, AGO Tumor is the usual addition for everyday uterine wellness — relevant later, when you come back to use the eggs.
- If you have had ovarian surgery, an endometrioma, or are working with one ovary, the combo does not change — but your expectations for yield should be set by your clinic, not by a blog.
If you are freezing embryos rather than eggs, your partner’s side matters too: sperm have their own 90-day window, which is what the Mom + Dad his-and-hers combo is built around.
Rules for taking anything alongside a stimulation cycle
This is the section to actually follow. Stimulation cycles are tightly controlled, and your clinic is responsible for what happens in them.
- Tell your clinic what you take, before stims start. Bring the physical bottles or photograph the labels — “some herbal thing” is not a useful answer for a nurse.
- If they say stop, stop. Some clinics ask patients to pause supplements during stimulation or around the trigger and retrieval. That instruction outranks anything on this page.
- Do not start anything new during the cycle itself. Build the routine in the months before, then hold it steady.
- Retrieval is a procedure with sedation. Ask your clinic well in advance what they want paused and how many days beforehand.
- Skip mega-doses and “fertility boost” stacks from three different brands at once. More products is not a better plan — see how to stack sensibly and who should ask a doctor first.
What to ask your clinic before you book — and what to sort out at home
Egg freezing in the US and Canada is a significant financial decision, and the questions below save people the most money and disappointment:
- “Based on my AMH and antral follicle count, how many eggs would you expect from one cycle — and how many cycles for the number I want stored?” Ask for the number in writing.
- “What is included in the quoted price, and what is not?” Medication, monitoring scans, anaesthesia and the first year of storage are often quoted separately.
- “What are the annual storage fees, and for how long can eggs stay stored here?” Storage is the cost people forget.
- “Eggs or embryos?” If you have a partner now, the answer changes the plan — and the conversation.
- “What would you want me to stop taking, and when?” Covered above, but ask it out loud.
At home: give yourself a real runway before the cycle, protect your sleep, and if you are over 35 do not let scheduling drift — time is the variable that matters most here. And if you decide later to use those eggs, the transfer prep is a separate plan: see the FET prep combo and what to do while waiting for IVF.
