Low Vitamin D status (serum <50 nmol/L) is consistently associated with frailty, muscle weakness, and increased mortality risk in elderly populations.

Check your Vitamin D levels if you are elderly or frail. Low levels are linked to muscle weakness and higher mortality. Supplementation is recommended for those at risk of falls or frailty, independent of bone health.

GoodSupportsHIGH confidence
A low vitamin D status is consistently associated with the frail phenotype... Frail individuals with a low vitamin D level were at increased risk (hazard ratio of 2.98) of death during the follow-up compared to robust individuals with a high level of vitamin D.
