2.1. Wpływ na wzrost i utrzymanie masy mięśniowej (ID 858, 1536, 1540, 4038, 4712)

The references provided in relation to these claims included textbooks, narrative reviews or monographs which did not provide any original data for the scientific substantiation of the claims and human intervention studies on the effects of food constituents other than the specific combination of food constituents which is the subject of some claims (ID 1536, 1540, 4712). The Panel considers that no conclusions can be drawn from these references for the scientific substantiation of the claims.
No human studies which investigated the effects of the food(s)/food constituent(s)/combination of food constituents on the growth or maintenance of muscle mass were provided in relation to any of the claims evaluated in this section.
Two references addressed the effects of the food(s)/food constituent(s) on muscle contractility, on the generation of free radicals and on lipid peroxidation in skeletal muscle in vitro using muscle biopsies and electrical stimulation. The Panel considers that evidence provided in in vitro studies is not sufficient to predict the occurrence of an effect of the consumption of the food(s)/food constituent(s) on the growth or maintenance of muscle mass in vivo in humans.
The Panel concludes that a cause and effect relationship has not been established between the consumption of the food(s)/food constituent(s)/combination of food constituents, which are the subject of the claims evaluated in this section, and growth or maintenance of muscle mass.

Some human intervention studies, which investigated the effects of the food(s)/food constituent(s) on the treatment of osteoarthrosis or (osteo)arthritis of different origin (rheumatoid arthritis, psoriatic arthritis, arthritis of infectious origin), were submitted. The Panel considers that the evidence provided does not establish that patients with osteoarthrosis or (osteo)arthritis of different origin are representative of the general population with regard to the status of joint tissues, or that results obtained in studies on subjects with osteoarthrosis or (osteo)arthritis of different origin and related to the treatment of symptoms of these diseases (e.g. erosion of articular cartilage, reduced mobility of joints) can be extrapolated to the maintenance of normal joints in the general population. Thus, for claims supported only by references to human studies on patients with osteoarthrosis or (osteo)arthritis of different origin, the Panel considers that a cause and effect relationship has not been established between the consumption of the food(s)/food constituent(s) and the claimed effect in the general population.
No human studies which investigated the effects of the food(s)/food constituent(s) on the maintenance of normal joints were provided in relation to any of the claims evaluated in this section.
A number of in vitro studies were provided which addressed the effects of different food(s)/food constituent(s) on human chondrocytes/cartilage explants, chondrocyte cell lines and expression of cell surface molecules. Studies on the relationship between the intake of the food(s)/food constituent(s) and the claimed effect in animal models of experimentally-induced arthritis were also provided.
The Panel considers that evidence provided in in vitro studies is not sufficient to predict the occurrence of an effect of the consumption of the food(s)/food constituent(s) on the maintenance of normal joints in vivo in humans.
The Panel concludes that a cause and effect relationship has not been established between the consumption of the food(s)/food constituent(s), which are the subject of the claims evaluated in this section, and maintenance of normal joints.
