You bought a 90-day supply, left it on a sunny windowsill or in a hot parcel locker, and now wonder: is it still good? Heat, humidity and time can affect any supplement, and a TTC routine only works if you can actually keep it going for a full cycle. Here’s a short, practical guide to storing, travelling with and judging your fertility supplements.
This is educational, not medical advice. The product label is always your first source — follow it over any general tip. For the bigger picture, see our fertility supplement buying guide.
1. The label beats every general rule
Look for the “best by” or “exp.” date and any storage line such as “store in a cool, dry place.” Many supplements are labeled with a date that applies to an unopened container stored as directed. If the label or the maker says something different from what you read online, go with the label — and ask the maker if it’s unclear.
2. Where to keep your bottles at home
| Good spot | Avoid |
|---|---|
| A kitchen cupboard away from the stove | Above the oven, next to the kettle or dishwasher |
| A bedroom drawer or dresser | Sunny windowsills |
| A dry shelf in the original container | The bathroom cabinet (shower steam = humidity) |
Keep the lid tightly closed, leave any desiccant packet in the bottle, and keep supplements out of reach of children and pets.
3. Heat, humidity and shipping: what to watch for
Summer parcels can sit on porches and in delivery vehicles, and winter shipments can freeze. When a package arrives, check three things:
- The seal is intact and the bottle isn’t cracked or leaking.
- The contents look and smell as they usually do — no melted, stuck-together or oddly discolored capsules, tablets or powder.
- The date leaves enough time to finish the bottle.
If anything looks off, don’t take it — photograph it and contact the seller. Ordering to the US or Canada? Our Canada ordering checklist covers delivery and duties.
4. Travelling, pill boxes and daily routine
For trips, a small weekly pill box is convenient, but fill it only for the days you need and keep it out of hot cars and checked-in luggage exposed to temperature swings. Carry supplements in your hand luggage in the original bottle if you can. Couples who travel separately can use our travel checklist.
5. When to replace and how to plan your supply
Don’t take anything past its date, with a damaged seal, or if it looks or smells wrong. To avoid gaps in a routine that is meant to run about 90 days, plan your reorder before the last bottle runs out — see the AGO combo pricing guide and our post on prenatal vs TTC formulas.

FAQ
Do fertility supplements expire?
Yes. Check the best-by or expiration date on the label, and don’t take a supplement past that date or if it looks or smells different than usual.
Should I keep fertility supplements in the fridge?
Only if the label says so. Most are stored in a cool, dry place away from heat, light and humidity.
Is it okay to store supplements in the bathroom?
It’s best to avoid it. Steam and temperature swings add humidity, which can affect many supplements.
My package sat in the heat for a day. Is it safe?
Check the seal and contents. If capsules or tablets look melted, stuck together or discolored, or smell off, don’t take them and contact the seller.
Can I put a few days of supplements in a pill box?
Yes for short periods, but keep the main bottle sealed in a cool, dry place and keep the pill box out of heat.
Do you ship to the US and Canada?
Yes. AGO ships to the US and Canada; the care team can confirm delivery times for your area.
