Assessing caffeine intake is a standard part of my fertility and reproductive health consults.
Because the impact of caffeine on sleep quality is one of the underestimated factors affecting fertility! 😱
If you're reading this and caffeine is disrupting your sleep - even subtly - it's affecting your fertility.
No, caffeine isn't the root of nutritional evil. But it's important to assess:
✅ How much are you having?
✅ Why are you having it? (Is it habit? Or because your energy is genuinely low, which might indicate other issues that caffeine is masking?)
✅ How is it affecting you individually? (Sleep quality, daytime energy, general health, menstrual cycle)
Some women can have coffee and sleep fine. Others are sensitive and don't realise the impact until they try removing it.
The key is tuning into your own body and honestly assessing whether caffeine is supporting your fertility or working against it.
For many women trying to conceive, reducing or eliminating caffeine during the luteal phase (second half of cycle) can make a noticeable difference in sleep quality and cycle symptoms.
It's worth experimenting.
