1. Caffeine-Based

Numerous energy boosters and weight loss supplements include caffeine. Regrettably, although this can provide a burst of energy, "these can irritate the bladder and make it secrete more often," Dr. Lahey warns. adding that they can also increase the urgency to urinate.

This is particularly worrisome for those with existing bladder issues or heightened sensitivity. Rather than turning to caffeine pills or supplements, he suggests opting for natural options such as green or chamomile tea in moderate amounts.

These alternatives provide a milder energy lift without putting too much strain on your bladder. Besides steering clear of caffeine supplements, it's wise to limit the consumption of caffeinated drinks like tea, coffee, or sodas. Overall, keeping an eye on your intake is essential.

2. High-Dose Vitamin C

Vitamin C is an essential nutrient that plays a crucial role in bolstering your immune system by defending against oxidative stress. Nonetheless, excessive intake can negatively impact your bladder. "Taking too much of it, especially more than 2000 milligrams a day, will cause inflammation of the bladder lining and frequent urge to urinate," Dr. Lahey warns.

To avoid these issues, he recommends sticking to the prescribed daily intake. It is always wise to obtain your nutrients directly from the foods you consume. Choose foods high in Vitamin C, such as strawberries, bell peppers, and oranges. This approach helps you fulfill your nutritional requirements without endangering your bladder.
