High Calorie Nutritional Drinks

High calorie nutritional drinks are specially formulated supplements designed to deliver maximum energy in a small, manageable volume. They are widely used by people who struggle to meet their daily calorie requirements through food alone — whether due to illness, recovery from surgery, reduced appetite, or increased metabolic demands.

At NutriSip, we stock a comprehensive range of high calorie drinks from leading brands including Fortisip, Ensure, Fresubin, and Calogen — all available for fast UK delivery.

Who Needs High Calorie Drinks?

High calorie nutritional supplements are commonly recommended for people experiencing unintentional weight loss, those recovering from surgery or illness, cancer patients undergoing treatment, elderly individuals with reduced appetite, and people with conditions that increase energy requirements such as COPD, cystic fibrosis, or chronic wounds.

A GP, dietitian, or hospital nutrition team will typically recommend a specific product and daily intake based on individual needs.

What Makes a Drink "High Calorie"?

Standard nutritional supplements typically provide around 1.0–1.5 kcal per ml. High calorie versions concentrate more energy into the same volume, usually delivering 2.0–3.0 kcal per ml. This means a small 125ml bottle can provide 300 kcal or more — equivalent to a light meal.

How to Get the Most from Nutritional Drinks

Timing matters: Take supplements between meals rather than replacing meals. This ensures they add to your overall intake rather than substituting food you would otherwise eat.

Serve chilled: Most patients find nutritional drinks more palatable when served cold. Some can also be frozen into ice lollies for variety.

Consistency is key: Regular daily intake as prescribed is more effective than occasional use. Set reminders if needed.

Variety helps: Rotate between flavours to prevent taste fatigue. Most ranges offer at least four or five flavour options.
