Dear Dr. Roach: I started taking betaine hydrochloride for my digestive health. I have had some ongoing issues, and my sister, the wellness guru, has been sharing some things she has learned and suggested this to me. In the first week I have noticed a difference. My wonderful partner, who is always skeptical, is wondering if there is true value with this supplement, so we are turning to you for some insight. J.Y.
Answer: Betaine hydrochloride has several purported uses. One is to improve athletic performance; however, the data are mixed about whether it is effective at improving muscle strength and endurance.
It also is used to relieve symptoms of gastroesophageal reflux disease and functional dyspepsia, a nonspecific term encompassing several types of stomach upset.
Betaine temporarily increases acid levels in the stomach (thats the same thing as a lower pH). This effect lasts a few hours, at least in one study of volunteers taking acid-suppressing drugs. Because of this, betaine hydrochloride has been used to help absorption of some medications.
However, there is no convincing evidence that this helps with symptoms. I am always concerned that an individual persons response could be due to the placebo effect, meaning that the difference you noted could be due to expecting to find some benefit from taking the supplement.
Betaine hydrochloride does not have many side effects in most people. Nausea, stomach upset, diarrhea and a body odor all have been reported.
I dont recommend betaine hydrochloride, but if it is helping and is not causing side effects, it is not likely to harm you.
Dear Dr. Roach: Does putting Neosporin in your nose protect against colds and flu? D.L.G.
Answer: No. Neosporin is a brand-name combination of antibacterial and antifungal antibiotics, very useful for protecting minor wounds and treating superficial infections, but is not effective against cold viruses or flu viruses. It doesnt filter out the viruses either, which are really, REALLY small, and which may also be transmitted by hands as well as being airborne.
Some people have noses that get very dry, even to the point of cracking, which may cause an infection in the nostrils as well as being very uncomfortable. An ointment in the nose acts as a moisture barrier; however, using an antibiotic ointment wouldnt be my first choice, as the antibiotic is not only unnecessary but can cause an allergic reaction in some people, so plain petrolatum (Vaseline or equivalent) is my recommendation. Other people like using a nasal saline spray.
