Leon Oat Milk Drinks: calories and sugar for every size

The 31 items in this section range from 10 kcal for the Espresso Macchiato (Oat Milk, Single) up to 401 kcal for the Hot Chocolate (Oat Milk, Large). The highest free sugar is the Hot Chocolate (Oat Milk, Large) at 38.0g, which is 127% of an adult's daily limit of 30g.

Boone separates free sugars from the sugars that occur naturally in milk and whole fruit, which NHS daily limits do not count, and measures every figure against the guideline for a specific age and sex rather than an adult average. Set the size and the milk in the calculator to see how any combination changes.

What nutrition information is shown for Leon Oat Milk Drinks?+

Each Leon Oat Milk Drinks item is listed with its calories, sugar, salt, saturated fat and protein, and how much of the daily guideline it uses. Open any item for the full breakdown, ingredients and allergens.

How does the Leon Oat Milk Drinks nutrition calculator work?+

Open any Leon Oat Milk Drinks item and set an age and sex. The calculator shows its calories, sugar, salt, saturated fat and protein as a share of that person's daily guidelines, and you can switch the size and milk.

Can I add sides and drinks to see a full Leon order?+

Yes. Start with any Leon Oat Milk Drinks item, then add food and drinks from across the Leon menu. The calculator totals the order and shows how it fits the daily guidelines for your age and sex.

How are the daily guidelines worked out for my age and sex?+

Boone uses UK government and NHS guidelines, which differ by age and sex. Saturated fat is limited to 20g a day for women and 30g for men, and free sugar to 30g for adults but 19g for children aged 4 to 6. Choosing an age and sex recalculates every figure against the right limits.

Why does the calculator show different figures for children?+

Children have lower limits for free sugar and salt and need less energy, so the same item uses a bigger share of their day. A child aged 4 to 6 has a limit of 19g of free sugar and 3g of salt, compared with 30g and 6g for an adult.

Where does Boone's Leon nutrition information come from?+

Boone uses the Foodie Fact Sheet and Barista Drinks Menu Leon publishes for its UK restaurants, September 2026 v1, then calculates free sugar, processing and how much of the daily guidelines each item uses for your age and sex.

Does the Leon Oat Milk Drinks nutrition information include allergens?+

Yes. Each Leon Oat Milk Drinks item page lists the allergens named in Leon's ingredient lists. Leon handles all 14 allergens in its kitchens and cannot guarantee any dish or drink is allergen free, so if you have an allergy, always check with the restaurant before ordering.

Why is the sugar figure different from Leon's own nutrition information?+

Leon publishes total sugar, which includes the sugar naturally found in milk and whole fruit. NHS limits apply only to free sugars, so Boone separates the two and measures free sugar against your daily limit. That is why an item can use less of your limit than its total sugar suggests.
