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.
2.5. Utrzymanie prawidłowego stanu kości (ID 663, 1915)
The claimed effect is “bones”. The Panel assumes that the target population is the general population.
In the context of the proposed wordings, the Panel assumes that the claimed effect refers to the maintenance of normal bone.
The Panel considers that the maintenance of normal bone is a beneficial physiological effect.
3.5. Utrzymanie prawidłowego stanu kości (ID 663, 1915)
A claim on protein and maintenance of normal bone has been assessed with a favourable outcome (EFSA Panel on Dietetic Products Nutrition and Allergies (NDA), 2010).
Three references were provided in relation to this claim. One was a review of the processes involved in the cross-linking of collagen starting on L-lysine and hydroxylysine residues, and the importance of collagen modelling for the mineralisation of the bone matrix (Knott and Bailey, 1998). Another was an overview of markers of bone turnover (Pagani et al., 2005). The third was a review of metabolic defects of collagen formation, and of post-translational modification as a cause of inherited disorders of connective tissue (Uitto and Lichtenstein, 1976). The Panel considers that none of the references refer to the role of dietary L-lysine in the maintenance of bone.
The Panel concludes that a cause and effect relationship has not been established between the consumption of L-lysine and the maintenance of normal bone, apart from the well established role of protein on the claimed effect.
