Overview Fractures and Falls and Vitamin D

It appears that at least 2,000 IU of vitamin D and 500 mg of Calcium are needed to substantially reduce falling

It appears that as little as 800 IU of vitamin D without any Calcium will reduce falling

Following paper range of vitamin D considered was from 66 IU to 1000 IU, with Median of 800 IU

Only 6 of their studies added Calcium to the vitamin D

Primary Care–Relevant Interventions to Prevent Falling in Older Adults:

A Systematic Evidence Review for the U.S. Preventive Services Task Force - Dec 2010

Background: Falls among older adults are both prevalent and preventable.

Purpose: To describe the benefits and harms of interventions that could be used by primary care practitioners to prevent falling among community-dwelling older adults.

Data Sources: The reviewers evaluated trials from a good-quality systematic review published in 2003 and searched MEDLINE, the Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and CINAHL from the end of that review's search date to February 2010 to identify additional English-language trials.

Study Selection: Two reviewers independently screened 3423 abstracts and 638 articles to identify randomized, controlled trials (RCTs) of primary care–relevant interventions among community-dwelling older adults that reported falls or fallers as an outcome. Trials were independently critically appraised to include only good- or fair-quality trials; discrepancies were resolved by a third reviewer.

Data Extraction: One reviewer abstracted data from 61 articles into standardized evidence tables that were verified by a second reviewer.

Data Synthesis: Overall, the included evidence was of fair quality.
In 16 RCTs evaluating exercise or physical therapy, interventions reduced falling (risk ratio, 0.87 [95% CI, 0.81 to 0.94]).
In 9 RCTs of vitamin D supplementation, interventions reduced falling (risk ratio, 0.83 [CI, 0.77 to 0.89]).
In 19 trials involving multifactorial assessment and management, interventions with comprehensive management seemed to reduce falling, although overall pooled estimates were not statistically significant (risk ratio, 0.94 [CI, 0.87 to 1.02]). Limited evidence suggested that serious clinical harms were no more common for older adults in intervention groups than for those in control groups.

Limitations: Interventions and methods of fall ascertainment were heterogeneous. Data on potential harms of interventions were scant and often not reported.

Conclusion: Primary care–relevant interventions exist that can reduce falling among community-dwelling older adults.

Average of all levels of Vitamin D decreased falls by 17%

Imagine how much decrease there would have been with 4,000 IU, as reported in other papers above

It has been known for over a decade that nerve conduction velocity speeds up with increased vitamin D - see following graph

Chart from ency editor Feldman 2005. Shows that those with slow muscle twitch are able to speed up response by taking vitamin D supplements.  PROOF

Whole Body Vibration is another excellent way to prevent falls.

Random Controlled Trials found that with just 5 minutes a day the amount of elderly falls was reduced by 2X.

Such a low amplitude of vibration was used that the participants could not notice if the platform was vibrating or not.

The wife of the administrator of this web site takes 10,000 IU of vitamin D AND uses the Whole Body Vibration Platform while doing dishes several times per week.
Parts cost of the platform is less than $200

Vitamin D supplementation and falls: a trial sequential meta-analysis July 2014

did NOT find that vitamin D affected rate of falls.
All of the detail is behind a $28 paywall, so it is impossible to understand the conclusion.
Suspect that a majority of the trials considered used

  1. Small doses of vitamin D
  2. Small time intervals.
  3. No or little Calcium

1 gram more of Calcium increases Hip Fracture risk by 30%
