Dietary supplementation taken by older individuals may reduce the risk of some chronic diseases although it would be unwise to assume that they are all effective and safe to use

In November 2018 researchers from France published their review on dietary supplement intake in the elderly. They stated that studies in older people using multivitamin supplements long-term had shown a potential reduced risk of developing age-related diseases. In addition, older people using omega-3 supplements had increased blood levels of omega-3 polyunsaturated fatty acids which appeared to be associated with fewer cardiovascular deaths. It had also been noted that when older people combined dietary protein supplementation with exercise there was a reduced loss of leg strength. However, some studies involving the use of purified flavonoids showed improved cognitive function, whereas no such effect was observed in a significant number of other studies.
