Could oily fish pills improve your teen's behaviour?

Teenagers are notorious for making poor food choices - favouring pizzas, fizzy drinks and crisps over proper balanced meals.

So it might sound as if the makers of Wellteen, a supplement made for teenagers 'tailored' for their developing brains, are on to something. Research seems to back this up - a recent study by the University of Oxford showed teenagers given the supplement for three months were better behaved than those given a placebo, according to teachers' ratings of behaviour. The researchers say it is the first study to show clearly that oral supplements can improve behaviour in healthy youngsters.

One key ingredient is omega 3 - the fatty acids vital for building connections between brain cells, which influences our behaviour. Our bodies can't make them, so we need to get them from our diet. Oily fish is the richest source of omega 3s. There is some evidence that a lack of omega 3 may be linked to an increased risk of behavioural problems.

A study in the International Review of Psychiatry in 2006 suggested deficiencies in omega 3 may lower levels of brain chemicals at critical periods of neuro-development, and lead to problems such as aggression. And a study in the journal Expert Review of Neurotherapeutics in 2013 reviewed this evidence and concluded that giving a multi-nutrient supplement could help treat anti-social behaviour and other psychiatric symptoms.
