If You Take Zinc, Will Your Feet Not Stink?

Some readers suggest one way to fight foot odor: take zinc supplements for a little while.

Do your feet smell bad? Many of the remedies for unpleasant foot odor are topical: soak the feet in a solution of baking soda, vinegar, Epsom salts or very strong tea. Any of those approaches may be quite helpful, but here is one that is less obvious: take zinc supplements. A reader shares his experience.

Life-Long Smelly Foot Problem:

Q. When I was a child, I had sweaty feet. Taking off my shoes would clear the room. All through high school, I wore closed toe sandals most of the year.

In the 1970s, I worked in downtown Chicago, and commuted by train from a western suburb. Most of the winter, snow or slush on the ground meant I had to wear galoshes to protect my shoes. Train cars were heated with vents at the floor level, so the floor was almost hot. Needless to say, my feet did sweat.

The skin between my toes cracked and hurt. My toe pads were wrinkled and pure white, and of course my feet smelled bad.

I tried a lot of fixes, such as foot powder and a nightly foot bath. Nothing helped. The dermatologist prescribed a foot bath with some kind of purple medication that stained the feet. It was absolutely no help, either.

Time to Take Zinc?

Then I read in Prevention magazine that smelly feet with cracks between the toes and wrinkled white toe pads could be caused by a zinc deficiency.

I started taking zinc tablets. Within the first day, the cracks between my toes closed up and the pads were no longer white or wrinkled. By the third day, the feet were completely cleared up: no sign of wrinkled white toes, the cracks completely healed, and as a bonus, no stinky feet. After about two weeks of zinc tablets, I began to notice a metallic taste in my mouth and decided it was time to stop taking the zinc tablets.

That revelation came in the mid 1970s. Since then, whenever my feet begin to smell, I take zinc tablets for a couple of days. I hope you can add this to your wealth of resources of home cures.

A. You are not the first person to tell us that systemic zinc may help control unpleasant odors. A number of European cosmetic products contain zinc-containing compounds to aid with odor (Abendrot & Kalinowska-Lis, International Journal of Cosmetic Science, Aug. 2018). 

Don’t Overdose When You Take Zinc:

The NIH Office of Dietary Supplements suggests a daily intake of 9 mg of zinc for women and 11 mg for men. The “tolerable upper intake limit” is 40 mg. Be careful not to exceed the limit, as too much zinc can be dangerous.
