You’ve booked your IVF cycle and your cabinet is full of bottles. Now the practical question: do you keep taking your fertility supplement once stimulation starts? The honest answer is that it depends on your clinic’s protocol — so the goal of this guide is to help you walk in with the right questions, not to replace your reproductive endocrinologist.
This is educational, not medical advice. For the full picture on timing outside of IVF, see our guide to fertility supplements to get pregnant.
1. Your clinic’s protocol comes first
IVF teams plan medications, monitoring and timing very precisely. Some clinics are comfortable with a prenatal and a few common supplements throughout; others ask patients to pause everything except a prenatal during stimulation. There is no single rule that fits every clinic, so treat the clinic’s written instructions as the final word and bring the exact bottle (or a photo of the label) to your next appointment. Never start, stop or change a prescription on your own.
2. Three phases, three different conversations
It helps to split the process into phases and ask about each one:
| Phase | What people usually ask | Who decides |
|---|---|---|
| Prep (about 3 months before) | Which supplements fit while I wait for my start date? | You + clinic |
| Active cycle (stimulation to retrieval) | Should I pause anything while on injectable medication? | Clinic protocol |
| Transfer and two-week wait | What is okay to take after transfer? | Clinic protocol |
The prep window is where most couples have the most flexibility. Our guides on IVF/IUI prep and egg-quality support before IVF or IUI cover that stage, and FET prep and the two-week wait cover the later ones.
3. Why the 90-day window matters before a cycle
Eggs and sperm develop over months, which is why many couples begin a preconception routine well before retrieval day. AGO Mom is a dietary supplement designed to support female reproductive wellness, and AGO Dad is designed to support sperm health. Neither is a medication and neither replaces your clinic’s protocol. If your cycle is still weeks or months away, you can have an informed conversation with your team about whether and when to continue them.
4. What to bring to your clinic appointment
- A photo of each supplement label (front and Supplement Facts panel).
- The daily dose and time you take each one.
- Any other products: prenatal, vitamin D, CoQ10, herbal teas.
- Your question in plain words: “Should I continue, pause, or switch during stimulation?”
Our doctor-conversation checklist has a ready-to-use script.
5. Don’t forget the partner’s side
Sperm health is part of every IVF and ICSI cycle, and the sperm used on retrieval day began developing roughly 90 days earlier. Many couples run both formulas in parallel so the windows match — see the his-and-hers starter combo. If you’d like help organizing a plan around your clinic’s calendar, get a free personalized plan. Results vary and no supplement guarantees pregnancy or IVF success.
FAQ
Can I take fertility supplements during an IVF cycle?
It depends on your clinic. Some allow a prenatal and selected supplements throughout, while others ask patients to pause most products during stimulation. Ask your reproductive endocrinologist and follow their written protocol.
Should I stop AGO Mom when IVF stimulation starts?
We can’t answer that for your cycle — only your clinic can. AGO Mom is a dietary supplement designed to support wellness, not a medication, but share the label with your team and follow their guidance.
Do supplements replace IVF medications?
No. Supplements are not a substitute for prescribed treatment. They are designed to support general reproductive wellness alongside your doctor’s plan.
How far ahead of IVF should we start?
Many couples begin a preconception routine about 90 days before, because egg and sperm development take months. Your clinic can tell you what fits your timeline.
Does the male partner need a supplement for IVF?
Sperm health still matters in IVF and ICSI. AGO Dad is designed to support sperm health; ask your clinic or urologist whether it fits your plan.
Does AGO ship to the US and Canada?
Yes. AGO ships to the US and Canada; the care team can confirm delivery times so your order arrives well before your cycle start date.
