1. Charakterystyka żywności / składnika

The food constituent that is the subject of the health claims is L-lysine.
Lysine is an indispensable alpha-amino acid which occurs naturally in foods mainly as part of proteins, and is provided by mixed dietary protein intakes from different sources. Lysine can also be consumed in the form of food supplements as L-lysine. The content of L-lysine in foods can be measured by established methods.
The Panel considers that the food constituent, L-lysine, which is the subject of the health claims, is sufficiently characterised.

2.3. Wzrost apetytu prowadzący do zwiększenia ilości przyjmowanej energii (ID 610)

The claimed effect is “to increase metabolism”. The Panel assumes that the target population is individuals wishing to increase their energy intake.
In the context of the proposed wordings and the clarifications provided by Member States, the Panel assumes that the claimed effect refers to an increase in appetite leading to an increase in energy intake.
The Panel considers that an increase in appetite leading to an increase in energy intake, if sustained, might be a beneficial physiological effect.

3.3. Wzrost apetytu prowadzący do zwiększenia ilości przyjmowanej energii (ID 610)

A consensus opinion on protein and amino acid requirements in humans, one reference on the effects of L-lysine on calcium metabolism in humans, and one human intervention study on the effects of lysine-supplemented wheat (versus unsupplemented wheat) in children in the context of lysine-devoid diets were provided in relation to the claim. The Panel notes that none of these references addressed the effects of lysine on appetite and subsequent energy intake. The Panel considers that no conclusions can be drawn from these references for the scientific substantiation of the claimed effect.
The Panel concludes that a cause and effect relationship has not been established between the consumption of L-lysine and an increase in appetite leading to an increase in energy intake.
