This study suggests repeated vitamin D checks may tell more than a single measurement in older adults.
Older patients whose vitamin D levels bounced around a lot over repeated tests were more likely to have sarcopenia, the age-related loss of muscle. Researchers looked back at records of 215 clinic patients aged 65 and up with at least two vitamin D readings. The hint here is that steady levels may matter more than one good reading. The link was weak, the study only looked backwards, and subgroup results faded after stricter statistical checks.
