Vitamin D deficiency can lead to chronic fatigue in the elderly. This has been shown by a study published in the journal. nutrients.
The authors of the new paper reviewed high-quality research on the role of vitamin D. Experiments suggest that the substance may affect mechanisms associated with fatigue, for example by activating genes that reduce inflammation in muscles or cell damage from free radicals. It also plays a role in the production of serotonin and dopamine, substances that play an important role in transmitting nerve signals and regulating mood.
There is a definite link between fatigue and vitamin D in the elderly and people with multiple sclerosis. There is less high-quality evidence on the effect of vitamin D on fatigue for people with rheumatism, cancer, and chronic fatigue syndrome.
Many studies have found a reduced risk of all-cause death with normal vitamin D levels, but the evidence is inconsistent and more research is needed.
Serum vitamin D levels below 20 ng/mL indicate deficiency, and levels between 21 and 29 ng/mL indicate deficiency. A daily intake of 600 to 800 IU of the vitamin ensures optimal bone health, and 1,000 to 2,000 IU is required to maintain levels above 30 ng/mL.
