7 Απρ 2023 · People over the age of 65 have been shown to produce less vitamin D. It is speculated that this may occur either because people over 65 go outside less or because it is harder to convert...
2 Φεβ 2014 · Llewellyn and colleagues examined 3,325 persons aged 65 and older and reported that individuals with low levels of vitamin D (<25 nmol/l) had a four times greater chance of developing cognitive impairment than individuals with higher vitamin D levels (>75 nmol/l).
This report reviews evidence on disorders related to inadequate vitamin D repletion in older people. Vitamin D is as essential for bone health in adults as in children, preventing osteomalacia and muscle weakness and protecting against falls and low-impact fractures.
To reach a 25OHD level of 20ng/ml (50nmol/l) the Institute of Medicine (IOM) set the RDA for vitamin D at 800 IU for people over age 70 years and 600 IU for ages 50–70 years.
28 Σεπ 2014 · Results from ecological, case–control and cohort studies have shown that high vitamin D levels were associated with a reduced risk of bone fracture, falls, autoimmune diseases, type 2 diabetes, cardio-vascular diseases and cancer.
26 Οκτ 2022 · Older adults are at risk for vitamin D deficiency as both production and metabolism of vitamin D change with aging due to factors, such as reduced sun exposure and reduced production capacity of the skin. Skeletal consequences of these age-related changes can include reduced bone mineral density, osteomalacia and fractures.
The goal for adequate Vitamin D status should be to reach a serum level of 25 (OH)D >50 nmol/l. It appears that daily low-dose vitamin D regimens reduce the risk of falling, especially in the elderly, compared with infrequent, large bolus doses that may increase it. The role of Vitamin D supplementation on muscle strength remains to be clarified.
