How Much Caffeine Is Too Much When You Are Trying To Conceive? Detailed Guide by an Expert

Caffeine is not advisable to women who are pregnant or trying to conceive, but that doesn’t mean you have to completely avoid it.

If you are trying to conceive, you may not need to give up your morning coffee completely. However, keeping a check on your total daily caffeine intake is important, particularly if you regularly drink several cups of coffee or tea.

“Keeping caffeine intake under 200 mg a day rather than having several caffeinated drinks throughout the day,” advises Dr Archana Batra, Dietitian and Certified Diabetes Educator.

Research on caffeine and fertility is not entirely consistent. The American Society for Reproductive Medicine (ASRM) says moderate caffeine consumption of around one to two cups of coffee a day does not appear to have adverse effects on fertility, while high intake of around 500 mg a day has been associated with reduced fertility.

Why Does Caffeine Matter When Trying To Conceive?

Caffeine is a stimulant found in coffee, tea, cola, energy drinks, chocolate and some supplements. While moderate intake does not appear to significantly affect fertility, higher consumption has been associated with poorer fertility outcomes in some studies.

The evidence does not mean that drinking a cup of coffee will prevent pregnancy. Instead, it suggests that people trying to conceive should avoid consistently high caffeine intake.

There is also another reason to be cautious: you may become pregnant before you know it. Caffeine intake is generally advised to be limited to 200 mg a day during pregnancy, with higher consumption linked to an increased risk of miscarriage and other pregnancy concerns.

How Much Caffeine Is In Your Daily Drinks?

The amount of caffeine can vary considerably depending on the type, size and strength of a drink. Therefore, simply counting cups may not give an accurate picture of your intake.
The NHS estimates that caffeine content can be approximately:

  • Instant coffee: 100 mg per cup
  • Filter coffee: 140 mg per mug
  • Tea: 75 mg per mug
  • Soft Drinks: 40 mg per can
  • Energy drink: up to 80 mg per 250 ml can
  • Dark chocolate: less than 25 mg per 50 g

These are only estimates, and actual amounts can differ between brands and serving sizes.
This makes it important to count total caffeine, rather than assuming that two or three drinks are automatically within a safe range.

For example, two mugs of filter coffee could already provide about 280 mg of caffeine, taking you above the commonly advised 200 mg daily limit.

What About Tea And Green Tea?

Switching from coffee to tea can reduce caffeine intake, but tea is not caffeine-free. Black and green tea both contain caffeine, and the amount depends on the variety, strength and brewing time.

If you enjoy several cups a day, consider replacing some with decaffeinated options. Checking labels can also help you keep track of less obvious sources of caffeine.

Should You Stop Caffeine Suddenly?

Not necessarily. If you regularly consume several cups of coffee or tea, suddenly stopping may cause withdrawal symptoms such as headaches, tiredness and irritability.

Dr Batra recommends gradually reducing caffeine intake rather than stopping abruptly, particularly for people who experience withdrawal headaches.

You could start by reducing the strength of your coffee, making one of your daily drinks decaffeinated or cutting down by one caffeinated drink every few days. This can make the transition easier.

Why Are Energy Drinks Best Avoided?

According to a study published in the journal 'Reproductive Toxicology', energy drinks can be particularly problematic when you are trying to conceive because they may contain substantial amounts of caffeine along with other stimulants and added sugar.

Dr Batra recommends staying away from energy drinks because of their combination of high caffeine, other stimulants and sugar. Their caffeine content can also make it easier to unintentionally exceed your daily limit. Additionally, energy drinks also affect heart health.

Instead, choose water or other suitable caffeine-free drinks for hydration.

Final Word

You do not necessarily have to eliminate caffeine completely while trying to conceive. However, keeping your total intake below 200 mg a day is a practical approach, particularly because pregnancy can occur before you know it. Pay attention to all sources, and if you currently consume large amounts, gradually cutting back may be easier than stopping overnight.
Most importantly, caffeine is only one part of preconception health. A balanced diet, appropriate folic acid supplementation, avoiding smoking and alcohol, maintaining a healthy weight and seeking medical advice when needed are also important when planning a pregnancy.
