2. Relieve Heartburn

Your pancreas naturally produces sodium bicarbonate (baking soda) to neutralizes the excess acid in the digestive system and prevent heartburn. Your kidneys also produce the substance, albeit, in smaller quantities.
Thus, you can use it to prevent acid reflux by taking ½ teaspoon of baking soda in 8 ounces of cold water after an acidic meal. Make sure not to lie down for at least an hour after taking it to make sure your stomach acid doesn’t creep up into your esophagus.
3. Eliminate A UTI

Baking soda can work to lower the acidity of your urine to kill acid-loving bacteria responsible for your urinary tract infection. To use, drink one teaspoon of baking soda in a tall glass of filtered water on an empty stomach. Stay hydrated throughout the day to flush out the infection.
Dr. Philippa Kaye explains: “A UTI is a urinary tract infection, an infection of the bladder (cystitis), urethra (tube which the urine travels through on the way out from the bladder), ureter (tube connecting the kidneys to the bladder), or the kidneys themselves.”
“UTIs are generally a bacterial infection and tend to occur when bacteria around the anus come in contact with the genitals and then can travel up into the bladder, for example during wiping after going to the toilet.”
“Some people find that it [baking soda] helps with the pain of a UTI, and there are some cystitis relief medications available over the counter which contain bicarbonate and citrates with the aim of neutralizing acid to make the urine less painful to pass and to also change the acidity within the bladder itself to stop bacteria multiplying to treat the UTI.” (3)
