Urinary Incontinence
Magnesium
In a double blind study, women with urge incontinence reported improvement after supplementing with magnesium.Dose:
150 mg twice daily
MagnesiumIn a double blind study, women with urge incontinence took approximately 150 mg of magnesum twice daily for one month, and reported improvement, including fewer episodes of urge incontinence, less frequent urination, and fewer awakenings at night to urinate.2 This confirmed an earlier double-blind study showing that a similar amount of magnesium reduced symptoms of urge incontinence.3Vinpocetine
In a small, preliminary study, some men and women with urge incontinence reported reduced symptoms and also improved in laboratory measures of bladder muscle control when supplementing with vinpocetine.Dose:
5 mg three times daily for two weeks, then 10 mg three times daily for two weeksVinpocetineVinpocetine is a semisynthetic derivative of vincamine, one of the major active compounds found in periwinkle. In a small, preliminary study, men and women with urge incontinence were given 5 mg of vinpocetine three times daily for two weeks, then 10 mg three times daily for an additional two weeks. About half of the subjects reported reduced symptoms of urge incontinence and also improved in laboratory measures of bladder muscle control.4 However, a small, double-blind trial found improvement in only one of several measures of urge incontinence.5 More double blind trials are needed to confirm these findings.Vitamin B12
Vitamin B12 deficency can cause urinary incontinence that may be corrected with supplementation.Dose:
See a doctor to test for deficiencyVitamin B12Vitamin B12 deficency can cause urinary incontinence that can be cured with B12 supplementation.6 One preliminary study,7 but not others,8,9 have found that low blood levels of B12 were associated with urinary incontinence in older people. Controlled trials are needed to determine whether B12 supplementation might be useful as a treatment for the common types of urinary incontinence.Vitamin D
Higher blood levels of vitamin D are associated with lower risk of urinary incontinence in women.Dose:
Refer to label instructionsVitamin DVitamin D may be important for normal muscle function, including muscles that help control urinary continence.10,11 Higher blood levels of vitamin D are associated with lower risk of urinary incontinence in women, according to one preliminary study.12 Controlled trials are needed to determine whether vitamin D supplements can help prevent or treat urinary incontinence.
