Training hard for a sports event can increase our requirements for nutrients involved in producing energy in the body such as the B vitamins – and different varieties of fish can boost intakes of these.

Find vitamin B1 (thiamin) in sea bassmackerel and plaice and vitamin B2 (riboflavin) in crabmeatmussels, flounder, whitingherring and mackerel.

Vitamins B3 (niacin), B6 and B12 are found in many different fish so eating a variety is the best way to boost intakes of these.
