Hi folks:

The dosage was: 5 mg folate and 1500 mcg B-12 daily, orally, to

produce an apparent 78% reduction in hip fractures (in stroke

patients):

" Effect of folate and mecobalamin on hip fractures in patients with

stroke: a randomized controlled trial.

CONTEXT: Stroke increases the risk of subsequent hip fracture by 2 to

4 times. Hyperhomocysteinemia is a risk factor for both ischemic

stroke and osteoporotic fractures in elderly men and women. Treatment

with folate and mecobalamin (vitamin B12) may improve

hyperhomocysteinemia. OBJECTIVE: To investigate whether treatment

with folate and vitamin B12 reduces the incidence of hip fractures in

patients with hemiplegia following stroke. DESIGN, SETTING, AND

PATIENTS: A double-blind, randomized controlled study of 628

consecutive patients aged 65 years or older with residual hemiplegia

at least 1 year following first ischemic stroke, who were recruited

from a single Japanese hospital from April 1, 2000, to May 31, 2001.

Patients were assigned to daily oral treatment with 5 mg of folate

and 1500 microg of mecobalamin, or double placebo; 559 completed the

2-year follow-up. MAIN OUTCOME MEASURE: Incidence of hip fractures in

the 2 patient groups during the 2-year follow-up. RESULTS: At

baseline, patients in both groups had high levels of plasma

homocysteine and low levels of serum cobalamin and serum folate.

After 2 years, plasma homocysteine levels decreased by 38% in the

treatment group and increased by 31% in the placebo group (P<.001).

The number of hip fractures per 1000 patient-years was 10 and 43 for

the treatment and placebo groups, respectively (P<.001). The adjusted

relative risk, absolute risk reduction, and the number needed to

treat for hip fractures in the treatment vs placebo groups were 0.20

(95% confidence interval [CI], 0.08-0.50), 7.1% (95% CI, 3.6%-10.8%),

and 14 (95% CI, 9-28), respectively. No significant adverse effects

were reported. CONCLUSION: In this Japanese population with a high

baseline fracture risk, combined treatment with folate and vitamin

B12 is safe and effective in reducing the risk of a hip fracture in

elderly patients following stroke.

Perhaps worth noting that because people on CRON weigh less than

average we exert less stress on our bones and therefore probably have

weaker bones unless we take specific steps to counteract the effects

of lower weight. Which suggests we may be at greater risk of hip

fractures than average. So the above may be a particularly pertinent

study for this group.
