Research suggests that vitamin D may help manage overactive bladder symptoms, but it is not a cure that completely resolves the condition.
Some studies have found that low levels of vitamin D may be linked to a higher risk of having overactive bladder (OAB). This vitamin is thought to play a role in muscle function and nerve signaling, including in the muscles of the bladder. One study looked at high-dose vitamin D supplementation and found that it could help reduce OAB symptoms in children with a type of OAB called “OAB dry.” However, while vitamin D might ease some symptoms, it doesn’t completely cure OAB. The idea is that by ensuring you have enough vitamin D, you may help your bladder muscles work better and lessen the urgency or frequency of your trips to the bathroom. It’s important to remember that vitamin D may be just one part of managing OAB, and its benefits can vary from person to person. If you’re thinking about taking vitamin D supplements for OAB, it’s best to talk with your doctor first. They can check your vitamin levels and advise what dose might be right for you as part of an overall treatment plan.
