Some people also view taking a daily multivitamin as another way to support a healthy lifestyle.

Fatigue affects up to three-quarters of older adults with chronic conditions. Some causes are obvious, while others are less well recognized.

Evidence supporting these diets comes from decades of randomized trials, population-based studies, and other research.
