Men and women are advised to not regularly drink more than 14 units a week. One unit is 10ml or 8g of pure alcohol. Because alcoholic drinks come in different strengths and sizes, units are a way to tell how strong your drink is.
You can view DrinkAware’s Unit and Calorie counter to understand the number of units and calories you consume whilst drinking.
