1. Charakterystyka żywności / składnika

The food constituents that are the subject of the health claims are "gamma-linolenic acid (GLA; C18: 3n-6) provided by evening primrose oil and/or borage (starflower) oil", "gamma-linolenic acid", "evening primrose oil (Oenothera biennis) contains gamma-linolenic acid", "borage oil (GLA= gamma linolenic acid)", "oenothera biennis-evening primrose-seeds oil", "long chain omega 6 polyunsaturated fatty acid GLA (gamma-linolenic acid)", "Borago officinalis", and "GLA (example from Borago officinalis, primrose oil, black currant seed oil)".
In the context of the proposed health relationships, wordings, conditions of use, and the clarifications provided by Member States, the Panel assumes that the food constituent that is the subject of the health claims is gamma-linolenic acid (GLA).
GLA is a n-6 long-chain polyunsaturated fatty acid which is present in small amounts in a variety of foods of both plant and animal origin and which can also be synthesised in the human body from its precursor linoleic acid (LA). GLA is a well recognised nutrient and can be measured in foods by established methods. This evaluation applies to GLA from all sources.
The Panel considers that the food constituent, gamma-linolenic acid (GLA), which is the subject of the health claims, is sufficiently characterised.

2.4. Udział w prawidłowym przebiegu procesów poznawczych (ID 1770)

The claimed effect is "cognitive and mental health". 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 contribution to normal cognitive function. Cognitive function includes memory, attention (concentration), learning, intelligence and problem solving, which are well defined constructs and which can be measured by validated psychometric cognitive tests.
The Panel considers that contribution to normal cognitive function is a beneficial physiological effect.

3.3. Udział w prawidłowym przebiegu procesów poznawczych (ID 1770)

Four references were provided to substantiate the claimed effect, including three narrative reviews and one systematic review. The narrative reviews summarised research on the effect of dietary gamma-linolenic acid on human health and nutrition, and did not provide original data for the scientific substantiation of the claimed effect. The systematic review was unrelated to the food constituent, which is the subject of the health claim. 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 gamma-linolenic acid and contribution to normal cognitive function.
