What is Nutri-Score?
Nutri-Score is a voluntary front-of-pack label developed by Santé publique France and used in several European countries. It summarizes nutritional composition per 100 g or 100 ml; it is not mandatory throughout the EU.
How is it calculated?
The calculation balances energy, sugars, saturated fat and salt against components such as fibre, protein, fruit, vegetables and legumes. Rules and thresholds depend on the food category and algorithm version; beverages have specific rules. France introduced the updated algorithm in 2025.
Components that increase the numerical score
Energy (kJ) · Sugars (g) · Saturated fat (g) · Salt (g)
Components that can reduce the numerical score
Fruits, vegetables, legumes (%) · Fibre (g) · Protein (g)
What do the grades mean?
- A — Most favourable profile on this scale
- B — More favourable profile
- C — Intermediate profile
- D — Less favourable profile
- E — Least favourable profile on this scale
Important limitations
A grade does not describe the whole diet, the portion you eat, allergens or individual suitability. It is not a processing classification or an additive safety assessment. Grades from different algorithm versions may differ.
Why some products show 'UNKNOWN'
UNKNOWN means no usable grade is available in the record. NOT-APPLICABLE is a separate recorded state. Neither is a favourable grade, and missing information alone does not establish why a grade is absent.
Our approach
TryVit presents the recorded grade alongside nutrition and ingredient information. A source grade does not establish which algorithm version was used unless that version is documented. Unknown provenance or version remains unknown.
