[헤럴드경제=장연주 기자] As we age, muscle and strength decrease, and right now, taking vitamin D supplements has been shown to have the effect of slowing down muscle strength, attracting attention.
According to MedicalXpress 15, a study found vitamin D supplements to be effective for dysapenia in the elderly.
The English Longitudinal Study of Aging (ELSA), which has been conducted for 15 years since 2002 by a research team led by Professor Thiago Alexandre of Gerontology at the Federal University of São Carlos (UFSCar) Faculty of Medicine in Brazil together to a research group from University College London (UCL) in the UK, result of data analysis.
Muscle weakness is the loss of muscle strength due to aging, partly due to muscle atrophy. When hypotonia occurs, the risk of falls, hospitalization, and death increases.
Among these data, the research team analyzed 4-year follow-up data from 3205 men and women 50 years of age and older who did not have hypotonia.
As a result, the research team found that those who took vitamin D supplements had a 78% lower incidence of muscle weakness than those who did not take vitamin D supplements.
Overall, people with blood vitamin D levels below 30 nmol/L had a 70% higher risk of muscle weakness than those with a normal level of 50 nmol/L or higher.
The strength level of the muscles can generally be determined by grip strength, which is normal for men over 26kg and over 16kg for women.
Bone and muscle tissue are not only related to each other structurally, but also biochemically, so endocrine disorders such as vitamin D deficiency can lead to decreased bone mineral density and decreased muscle mass, strength and function, explained the research team. .
Vitamin D is a nutrient that helps the body absorb calcium and protects bone health, but it’s also known to regulate cell growth, immune function, and inflammation.
Vitamin D is synthesized in the body through skin exposed to ultraviolet rays from the sun. 90% of the vitamin D our bodies need is provided through exposure to sunlight. Daily exposure of 10% of the skin to ultraviolet rays for 15-30 minutes produces a sufficient amount of vitamin D in the body.
Among foods it is contained in fatty fish (salmon, tuna, mackerel), liver, egg yolk, cheese, etc. Vitamin D can be consumed through cereals and milk and vitamin D supplements.
The results of this study were published in the latest issue of Calcified Tissue International and Musculoskeletal Research.
