Vitamins That Can Help With Sweaty Feet

While good hygiene practices like washing and drying your feet properly are important, making sure you get enough of certain vitamins and minerals in your diet can also help combat excessive foot perspiration. Here are some of the key vitamins and supplements to consider taking if you regularly deal with sweaty feet.

Vitamin B6

One of the B complex vitamins, vitamin B6 plays a role in several important body functions. Some research indicates it can help reduce sweat production. Vitamin B6 helps regulate levels of nitric oxide in the body. Nitric oxide is involved in the activation of sweat glands. By keeping nitric oxide levels balanced, vitamin B6 may be able to curb excessive sweating including on the feet. Foods high in vitamin B6 include chicken, fish, potatoes, chickpeas and bananas. Taking a daily B complex vitamin supplement can also boost your intake of B6.

Vitamin C

Vitamin C is an essential antioxidant that is needed for many vital bodily processes. Among its long list of benefits, vitamin C may also have the ability to control sweating. It is believed that adequate vitamin C levels help regulate sweat production. Vitamin C deficiency could potentially lead to increased perspiration. Getting enough vitamin C from foods like oranges, kiwi, red peppers and strawberries or a supplement may help normalize sweat gland function.


The mineral zinc plays a key role in immune system health, wound healing, protein synthesis and DNA production. Zinc may also help regulate the amount of sweat your body produces. It is needed for the proper functioning of the apocrine glands that produce sweat. Without sufficient zinc levels, these sweat glands could become overactive leading to excess sweat on the feet and body odor. Zinc can be obtained from foods like meat, shellfish, nuts and legumes or chelated zinc supplements.


Magnesium is an essential mineral that most people could use more of in their diet. One of its roles involves influencing neurotransmitter production and nerve conduction. This can impact how your sweat glands receive signals from the brain. Getting enough magnesium from spinach, avocados, almonds and other sources may support normal sweat gland stimulation and reduce instances of sweaty feet.

Omega-3 Fatty Acids

Omega-3s provide wide-ranging health benefits from heart and brain support to anti-inflammatory effects. Some evidence shows they may also minimize excessive sweating. Omega-3s help regulate the body’s autonomic nervous system which controls sweat production. Fatty fish like salmon and tuna contain high amounts of omega-3s. You can also take fish oil supplements to increase your intake if needed.

In addition to making sure you get enough of these important vitamins and minerals, maintaining good foot hygiene habits can also go a long way towards combating sweaty feet. Wear breathable socks, wash and dry your feet thoroughly, use foot powder and change your socks frequently to help control foot odor and perspiration issues. But adding in sources of vitamins B6, C, zinc, magnesium and omega-3s can provide extra support against overactive sweat glands. Getting enough of these essential nutrients may help you keep your feet dryer and more comfortable.
