Q. I seem to be lacking in energy. What should I try to include in my diet to hopefully give me a bit more zest?

Dr Emma Derbyshire, advisor to the Health & Food Supplements Information Service, is here to help.

Tiredness all the time, also known as TATT, is a common problem of modern life. Foods providing B vitamins help reduce tiredness and fatigue. Iron is another important nutrient, with shortfalls linked to iron deficiency and iron deficiency anaemia. Eating foods rich in this should help to boost energy levels, alongside maintaining a regular sleep pattern.

Make sure you are consuming enough water, too. Women should aim for two litres and men two and a half litres of fluids daily from food and drink sources. Water, tea and herbal teas can all count, alongside foods with a high water content.

Taking a combined multivitamin and multimineral daily, as well as a proven omega-3 supplement like Equazen, can help top up dietary intakes.
