1. Charakterystyka żywności / składnika

The food constituent that is the subject of the health claim is green lipped mussel or green lipped mussel extract.
The New Zealand green lipped mussel, Perna canaliculus, is a bivalve native marine mussel from the mollusc family Mytilidae distinguishable from other bivalve species (Wolyniak et al., 2005).
Green lipped mussel extract is a lipid rich freeze dried powder extract of this mollusc. The main lipid classes contained in the lipid fraction are triacylglycerols, sterols, sterol esters, free fatty acids and polar lipids (Murphy et al., 2002, 2003; Wolyniak et al., 2005). The major fatty acids present are eicosapentaenoic acid, docosahexaenoic acid and palmitic acid. Cholesterol is the most prominent sterol (Gibson and Gibson, 1998; Murphy et al., 2003). No major differences were found in the lipid, fatty acid and sterol composition between green lipped mussel samples from three different sites in New Zealand using different sample treatments (Murphy et al., 2003). However, multiple factors such as seasonal variations, lifecycle, sex, variation of plankton in different seasons and temperature account for differences in the lipid content and composition of mussels (and their extracts), which could influence their physiological effects (Li et al., 2007; Murphy et al., 2002).
The Panel considers that the food constituent, green lipped mussel or green lipped mussel extract, which is the subject of the health claim, is not sufficiently characterised.

The claimed effect is “joint and musculoskeletal system health”. The Panel assumes that the target population is the general population.
In the context of the proposed wordings, the Panel notes that the claimed effect relates to the maintenance of normal joints, bone and muscles.
The Panel considers that the maintenance of normal joints, bone and muscles is beneficial to human health.

3. Naukowe uzasadnienia wpływu na zdrowie człowieka - Utrzymanie prawidłowego stanu stawów, kości i mięśni

The human studies provided on the effects of green lipped mussel extract on joint health (e.g. joint pain, joint structure/function) have been conducted in patients with clinical diagnosis of (primarily knee) osteoarthritis (OA). OA is the most common joint disease worldwide (Issa and Sharma, 2006; Corti and Rigon, 2003; Arden and Nevitt, 2006) and a major cause of disability (Hunter et al., 2008; Pollard and Johnston, 2006; Sarzi-Puttini et al., 2005; Ethgen et al., 2004).
The Panel considers that the evidence provided does not establish that patients with OA are representative of the general population with regard to the status of joint tissues, or that results obtained in studies on subjects with OA relating to the treatment of symptoms of this disease (e.g. erosion of articular cartilage, reduced mobility of joints) can be extrapolated to the maintenance of normal joints in the general population.
The Panel also considers that the evidence provided in the animal studies submitted does not predict the occurrence of an effect of either green lipped mussel or green lipped mussel extract intake on the maintenance of normal joints in humans.
No data were presented in relation to the effects of green lipped mussel or green lipped mussel extract on the maintenance of normal bone and muscles.
The Panel concludes that a cause and effect relationship has not been established between the consumption of green lipped mussel or green lipped mussel extract and the maintenance of normal joints, bone or muscles.
