- Vitamin D for adults and elderly – review Oct 2018
- Shin pain in elderly men 36 X more likely if low vitamin D – March 2017
- Half of Women Over 50 Desperately Need This Potent Nutrient (Vitamin D) – April 2018
- 4,000 IU of Vitamin D is OK - 19 organizations agree - 2018
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
Seniors category has431 items Studies in Senior plus some other categories in VitaminDWiki

- Reduced muscle function in mice lacking Vitamin D Receptors in muscles – June 2019
- Vitamin D and Ageing (29 page chapter, VDR decreases with age) – Feb 2019
- Less vitamin D gets to cells as you age - fewer Vitamin D Receptors - 2004
- Aging leads to a decrease of vitamin D getting to cells – Sept 2017
- Sepsis is 13 X more likely if poor Vitamin D Receptor – April 2017

- 13 reasons why many seniors need more vitamin D (both dose and level) - July 2023
- Sarcopenia (muscle loss) fought by Vitamin D, exercise and protein - many studies
Other important items for Seniors
- Elderly skin produces about 3X less vitamin D from the sun/UV
- Elderly get about 3X less vitamin D from the stomach
- Vitamin D Receptor, which can restrict vitamin D from getting to cells, gets worse with age
- One-a-day vitamins rarely have enough vitamin D to provide any benefit at all
- Need only take 2 capsules per month - rarely need to worry about forgetting
- Several studies have found that infrequent dosing is better than daily for seniors
- Typically need more Vitamin D if in poor health
- UV lamps are low cost and a good source of Vitamin D (especially if not outdoors much
- Can fortify food with Vitamin D at home

The following are just the right columns of Table 1Autonomy and mobility are, in many cases, key elements underlying positive ageing. Vitamin D (vitD) is essential to maintaining musculoskeletal health and hence mobility; ensuring adequate vitD status is important in positive ageing. However, vitD deficiency persists in ~10–30% of older adults in the Western world. The aim of this review was to explore older adult vitD beliefs, knowledge and preferences, in order to identify means to prevent vitD deficiency respectful of older peoples’ autonomy. Academic search-engines were used to explore the research literature with the keywords: vitamin D; older adults; preferences; knowledge; practices; beliefs. 22 recent studies were identified; although the majority of older people knew of vitD, knowledge about increased fall risk secondary to deficiency was limited and knowledge did not always correlate with adequate intake or status.
There was evidence of confusion regarding vitD food sources, sun-exposure and health benefits, and although General Practitioners were trusted information sources they often did not discuss vitD with patients.
Preferences varied significantly depending on geographic location, ethnicity, socioeconomic status, education and cultural factors; overall, older people wanted more clear information about vitD.
In conclusion, older people have a relatively high awareness of vitD, however, knowledge may be inaccurate and low in those most at risk, and knowledge of deficiency-associated fall risk is under-recognised. Furthermore, studies specifically addressing older adult preferences are lacking; an understanding of preferences, integrated into public health guidelines and implementation strategies, is key not only to decreasing the risk of vitamin D deficiency but also to enabling autonomy in older adults.Older adults need to know more about Vitamin D – June 2018(Cached) Printer Friendly Follow this page for updates7178 visitors, last modified 01 May, 2019, This page is in the following categories (# of items in each category)Attached files
