Key Considerations

Teenagers need more protein per kg than adults due to growth
NHS reference nutrient intake: 42-55g/day for teenagers (varies by age and sex)
Active and athletic teenagers may benefit from 1.4-2.0g/kg/day
Protein from food is always preferable to supplements for teenagers
Most UK teenagers already meet basic protein requirements through normal eating
Excessive protein supplementation is unnecessary and may displace other important nutrients

Specific Adjustments

General Teenagers

NHS guidelines of 42-55g/day are easily met through balanced eating. Focus on including protein at each meal.

Athletic Teenagers

Active teens training regularly may benefit from 1.4-2.0g/kg/day, met through food first (meat, fish, eggs, dairy, legumes).

Tips for Best Results

1Prioritise whole food protein sources: chicken, fish, eggs, dairy, beans, and lentils

2Protein supplements are generally unnecessary for teenagers eating balanced diets

3Include protein at breakfast (eggs, yoghurt) to support concentration and satiety

4Chocolate milk is an effective and enjoyable post-training recovery drink for teen athletes

5If concerned about nutrition, consult a GP or registered dietitian rather than following online advice

Frequently Asked Questions

Should teenagers take protein shakes?

For most teenagers, protein shakes are unnecessary. A balanced diet provides sufficient protein. If a teenage athlete struggles to eat enough, a protein shake can supplement food — but food should come first.

How much protein does a teenage athlete need?

Active teenagers benefit from 1.4-2.0g per kg bodyweight daily. For a 65kg teen, that is 91-130g/day. This is achievable through food: chicken breast (30g), eggs (12g), milk (10g), pasta with meat sauce (25g).

Is too much protein harmful for teenagers?

Very high protein intake (over 3g/kg) is unnecessary and may displace carbohydrates needed for energy and micronutrients needed for growth. Stick to 1.4-2.0g/kg for active teens.
