People who take multivitamin supplements tend to have better overall health, a new study has found.
Researchers at the University of California analysed a group of long-term supplement users and compared their health to people who took single supplements and a control group who took no dietary supplements.
They found that the group of 278 long-term supplement users, who took an array of vitamin, mineral and herbal dietary supplements every day for at least 20 years, were 73 per cent less likely to have diabetes and 39 per cent less likely to have high blood pressure than non-users.
Dr Gladys Block, professor of epidemiology and public health nutrition at the University of California at Berkeley School of Public Health, said: "The study results were very impressive and support the potential benefits of long-term use of dietary supplements."
The findings are published in Nutrition Journal and represent the first ever study on long-term users of multiple dietary supplements.
