13 reasons why many seniors need more vitamin D (both dose and level) - July 2023 has the following
- Senior skin produces 4X less Vitamin D for the same sun intensity
- Seniors have fewer vitamin D receptor genes as they age
Receptors are needed to get Vitamin D in blood actually into the cells - Many other Vitamin D genes decrease with age
- Since many gene activations are not detected by a blood test,
more Vitamin D is often needed, especially by seniors - Seniors are indoors more than when they were younger
not as agile, weaker muscles; frail, no longer enjoy hot temperatures - Seniors wear more clothing outdoors than when younger
Seniors also are told to fear skin cancer & wrinkles - Seniors often take various drugs which end up reducing vitamin D
Some reductions are not detected by a vitamin D test of the blood
statins, chemotherapy, anti-depressants, blood pressure, beta-blockers, etc - Seniors often have one or more diseases that consume vitamin D
osteoporosis, diabetes, Multiple Sclerosis, Cancer, ... - Seniors generally put on weight as they age - and a heavier body requires more vitamin D
- Seniors often (40%) have fatty livers – which do not process vitamin D as well
- Reduced stomach acid means less Magnesium is available to get vitamin D into the cells
- Vitamin D is not as bioavailable in senior intestines
- Seniors with poorly functioning kidneys do not process vitamin D as well
- Glutathione (which increases Vitamin D getting to cells) decreases with age

Background
Hypovitaminosis D and depressive syndromes are common conditions in old adults. However, little is known about the relationship between vitamin D and depression in exceptional aged people. The objective of this study is to evaluate the relationship between vitamin D levels and depressive symptoms in Chinese longevous persons.Methods
We used a dataset from a cross-sectional survey of a sample of Chinese longevous people with self-reported age 100 or older, including 175 men and 765 women, was conducted from June 2014 to December 2016 in Hainan Province, China. Data on demographics, lifestyle characteristics and health conditions were collected using a structured questionnaire. Anthropometrics and blood samples were obtained following the standard procedure. Depressive symptoms of the participants were assessed using a shortened version of the Geriatric Depression Scale (GDS-15). Serum vitamin D levels were measured using an automated radioimmunoassay.Results
The prevalence of longevous persons with depressive symptoms among the sample was 32.2% (95% confidence interval: 29.7–34.7%). Serum vitamin D levels were lower in participants with depressive symptoms than in those without (20.8 ± 8.7 vs. 23.7 ± 9.7, ng/mL).
Vitamin D deficiency was an independent risk factor for depression after controlling for the potential covariates (Odds ratio = 1.47, 95% Confidence interval = 1.08–2.00; p = 0.014). A negative relationship between serum vitamin D levels and depressive symptoms was also detected, and the relationship remained significant after adjusting for a wide range of other covariates. The multivariate adjusted odds ratio of depressive symptoms for the lowest versus highest quartiles of vitamin D levels was 1.73 (95% confidence interval: 1.10–2.72), and the adjusted odds ratio with a 5 ng/mL decrement of serum 25OHD levels was 1.10 (95% confidence interval: 1.01–1.19).Conclusions
This study showed an inverse association between vitamin D levels and depressive symptoms among Chinese longevous persons. Depressive symptoms should be screened in longevous persons who had vitamin D deficiency. Further studies on vitamin D supplement and prevention along with treatment of depression are needed among very old population.Centenarians with good vitamin D were 1.5 X less likely to depressed – Aug 2018Printer Friendly Follow this page for updates8749 visitors, last modified 20 Oct, 2018, This page is in the following categories (# of items in each category)
