Tommy's Charity - the leading baby Charity, which focuses on saving babies' lives - has launched a Caffeine Calculator.

Tommy's fund pioneering medical research into the causes and prevention of miscarriage, premature birth and stillbirth. As part of their work, they are campaigning to increase awareness about the effect of caffeine on pregnancy.

According to the Tommy’s Charity website:

Over-consumption of caffeine (more than 200mg daily) is linked to miscarriage, low birth-weight and fetal growth restriction, but many women are unaware what 200mg represents in real life.

Caffeine is ‘hidden’ in many products including chocolate and energy drinks

Tommy’s caffeine calculator helps women track their consumption

Since 2008 the Food Safety Authority (FSA) has recommended that pregnant women keep their caffeine intake to under 200mg a day, but evidence from Tommy’s, the pregnancy and baby charity, shows that women do not know what 200mg caffeine represents and are over-consuming.

A poll of 4,100 pregnant women conducted by Tommy’s showed that 61% would reduce their caffeine consumption habits after being made aware of how much caffeine there is in daily items.

Babies of pregnant women who consume over 200 mg of caffeine per day are at an increased risk of fetal growth restriction which could result in low birth weight and/or miscarriage.

“There is evidence that excessive caffeine intake  is associated with an increased risk of miscarriage. Interestingly, this evidence seems to apply to not just women during pregnancy, but also to men, pre-conception. Although more research is required, most clinicians would recommend couples to restrict their caffeine intake.”

Professor Arri Coomarasamy, Clinical Director of Tommy’s National Miscarriage Research Centre

Caffeine is found in tea and coffee, cola, other soft beverages such as energy drinks and chocolate. A mug of tea has around 75mg and a bar of plain chocolate has around 25mg.

“Caffeine consumption can add up so quickly! Two cups of coffee and a bar of chocolate would have enough caffeine to be over the recommended limit while pregnant. Try switching to decaffeinated coffee, herbal teas, fruit juice and water. Don’t worry if you have in the past gone over the 200mg limit but using a caffeine calculator now can help you be more aware of your consumption and to cut down if you need to.”

Sophie King, Tommy’s midwife
