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.  
                 
                 
	        
        
        
        
        
                
2.2. Utrzymanie prawidłowego stężenia cholesterolu LDL we krwi (ID 454, 4669)
                
                
                    The claimed effects are “for cardiovascular system functions” and “lowers cholesterol levels”. The  Panel assumes that the target population is the general population.  
In the context of the proposed wordings and the clarifications provided by Member States, the Panel  assumes that the claimed effect refers to the maintenance of normal blood LDL-cholesterol  concentrations.  
Low density lipoproteins (LDL) carry cholesterol from the liver to peripheral tissues, including the  arteries. Elevated LDL-cholesterol, by convention >160 mg/dL (>4.1 mmol/L), may compromise the  normal structure and function of the arteries.  
The Panel considers that the maintenance of normal blood LDL-cholesterol concentrations is a  beneficial physiological effect.  
                 
                 
	        
        
        
        
        
                
3.2. Utrzymanie prawidłowego stężenia cholesterolu LDL we krwi (ID 454, 4669)
                
                
                    A consensus opinion on protein and amino acid requirements in humans, and a website which did not  provide any original data, were provided in relation to the claim. The Panel notes that none of these  references addressed the effects of L-lysine on blood LDL-cholesterol concentrations. 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 the maintenance of normal blood LDL-cholesterol concentrations.
