Alcohol units

Units are a way of expressing the quantity of pure alcohol in a drink.

The NHS recommends:

  • Men should not regularly drink more than 3-4 units of alcohol a day
  • Women should not regularly drink more than 2-3 units a day

“Regularly” - means drinking this amount every day or most days of the week.
