Daily Caffeine Calculator

Add up the caffeine you have in a day from coffee, tea, cola, energy drinks, chocolate and HYP pouches. The figures come from the NHS and from the brands' own labels. EFSA's guidance for healthy adults is up to 400mg of caffeine a day from all sources, and up to 200mg in one go. The NHS advises no more than 200mg a day if you are pregnant.

How much caffeine is too much?

EFSA (the European Food Safety Authority) advises that for healthy adults, up to 400mg of caffeine a day from all sources, and up to 200mg in one go, does not raise safety concerns. The NHS advises no more than 200mg a day if you are pregnant. People differ, so if caffeine affects you, or you take medication, are going through the menopause or have a heart or blood pressure condition, speak to your GP or pharmacist about what is right for you.

Where do these figures come from?

Coffee, tea, cola, 250ml energy drink and chocolate figures are the NHS's own approximate amounts. The Monster Energy figure is from the brand's UK label (32mg per 100ml). Amounts vary by brand, cup size and how drinks are made, so treat totals as a guide. A HYP pouch contains 100mg of caffeine.

What time should I have my last caffeine?

EFSA notes that caffeine taken close to bedtime can affect sleep in some adults. Many people choose a personal cut-off time in the afternoon. Count every source, including tea, cola and chocolate.

How many HYP pouches can I use in a day?

Maximum 4 pouches a day, 3 to 4 hours apart. Count them with your other caffeine. Four pouches is 400mg on its own.

18+. Contains caffeine (100mg per pouch). Not suitable for children, anyone pregnant or breastfeeding, or people sensitive to caffeine. Maximum 4 pouches a day, 3 to 4 hours apart.
