Because baking soda is readily available and inexpensive, it makes the perfect addition to your home’s medicine cabinet, cleaning-supply kit, and beauty routine, and it’s safe enough to use every day.

Before we examine all the many uses for baking soda, let’s figure out what makes this natural ingredient so versatile and helpful.


Understanding Baking Soda

You probably have a box of baking soda in your house right now.

While baking soda is a familiar ingredient to most of us, you may also know it by its many other names, which include sodium bicarbonate, sodium hydrogen carbonate, bread or cooking soda, and bicarbonate of soda.

Baking soda is a molecular compound that’s made up of sodium, hydrogen, carbon, and oxygen.

Baking soda is alkaline, and it has a pH level of 9.

But what is pH, and why is it important?

All substances have a pH level, which is merely a measure of how alkaline or acidic it is.

Even human beings have a pH level.

Ions that are positively charged create a more acidic pH level, and ions that are negatively charged create an alkaline pH level.

Your body naturally wants to live at a balanced pH level.

While much of the baking soda used today is human-made, sodium bicarbonate does occur naturally, as well.

It’s known as a nahcolite, which is found in mineral form in many places around the globe.

Commercial mines for sodium bicarbonate exist in Kenya, Botswana, and the United States, and there are large deposits in other counties as well.

It’s important not to confuse baking soda with baking powder.

While baking soda is pure sodium bicarbonate, it contains both sodium bicarbonate and one or more acid salts.

While both baking powder and baking soda are used as leavening agents in baking, baking powder contains additional ingredients that make it inappropriate for all of the uses for baking soda we describe below.


Health Benefits of Baking Soda

Baking soda offers many fantastic health benefits for you and your family.

As a natural remedy and treatment, baking soda has been used all over the world for centuries.

It treats a number of common illnesses and injuries.

Your body actually manufactures its own bicarbonate in the kidneys, and it uses this compound to counterbalance the acidity that naturally occurs in your body.

If you’re not making enough bicarbonate on your own to lower your level of acidity, baking soda can even be used as a natural supplement for this essential nutrient.


Boosts Kidney Health

Because the kidneys are responsible for your natural bicarbonate levels, individuals with chronic kidney disease often have low blood-bicarbonate levels.

When patients with chronic kidney disease were given baking soda as a treatment, their disease progression significantly slowed down, and more patients stayed healthier longer.

Anyone who took baking soda as a supplement was also less likely to develop an end-stage renal disease, which is fatal.

Baking soda has been shown to slow disease progression, improve the overall prognosis, and improve the overall nutritional status of those with chronic kidney disease (1).


Baking Soda Soothes Digestive Problems

As a natural alkaline, baking soda is great for neutralizing acid within your body, and the #1 place where acid can easily wreak havoc is in your digestive system.

For treating heartburn and acid reflux, baking soda is a quick, easy, effective treatment (2).

If you’ve consumed too many acidic foods or drinks, slowing sipping on a mixture of baking soda and water can bring your pH levels back into alignment and neutralize some of the acids in your system.


Helps Your Skin

If you have itchy skin due to psoriasis, an allergic rash, insect bites, sunburn, or eczema, baking soda can naturally soothe and calm irritation.

The alkaline nature of baking soda promotes the lowering of inflammation, and a paste made from baking soda and water can draw out allergens and toxins that cause itching.


Helps with UTIs

Urinary tract infections (UTIs) are among the most common infections, especially among women.

For some women who experience chronic or prolonged symptoms from these infections, baking soda is an excellent treatment for lowering the acidic level of their urine (3).

While baking soda may not work in all women who suffer from UTIs, it can be an effective, inexpensive treatment for many.


Kills Microbes

Baking soda has antifungal and antibacterial properties that make it an excellent treatment for certain kinds of fungi and bacteria.

As a treatment for skin and nail infections, baking soda is effective at eliminating several types of yeasts, molds, and dermatophytes that cause infection (4).

In addition, baking soda is very effective at treating Streptococcus mutans, which is a bacteria that’s one of the leading causes of tooth decay (5).


Reduces Soreness and Fatigue

Strenuous exercise and athletic training produce acid in the body, especially the muscles.

Anyone who’s training regularly or looking to boost their performance can benefit from taking sodium bicarbonate before exercising.

This bicarbonate-loading activity serves to reduce acid levels within the body during exercise, which results in less muscle damage, reduced soreness, and more energy to sustain exercise (6).

Sodium bicarbonate seems to be most effective for short durations of strenuous exercise, as well as intermittent, sustained sessions that involve high-intensity training (7).

Many athletes who use bicarbonate-loading experience less muscle fatigue and improve their overall performance (8).


Helps during Chemotherapy

One of the unpleasant side effects of chemotherapy is that the chemicals used during treatment cause unwelcome changes to your mouth and throat.

Chemotherapy treatments destroy the good bacteria that are naturally present in your mouth and throat; this allows yeasts like candida albicans to flourish, which results in oral thrush (a type of yeast infection).

You can use baking soda to rinse the mouth and gargle, which helps control yeasts and other side effects from chemotherapy.

When your mouth and throat feel better, you’re more likely to eat and drink, which are necessary for optimal recovery from this harsh treatment.

Three times a day, rinse with a mixture of warm water, a 1/4 teaspoon of baking soda, and a 1/8 teaspoon of sea salt.

Then rinse with plain water.


Treats Kidney Stones

If you suffer from kidney stones, baking soda can help reduce your symptoms and decrease the formation of new stones (9).

Baking soda effectively removes the compounds that cause stones to form in your body.

There are many more important, interesting health benefits of baking soda.

We’ll cover them later, as we reveal all of the many uses for baking soda in your home.

Then we’ll even share a few of our favorite home remedies, which highlight the healthy powers of baking soda.

This multifunctional product can also improve your kidney function.

When your kidneys aren’t functioning well, they have a hard time keeping your pH balance in check.

Supplementing with oral sodium bicarbonate can reduce acids in your system, which will assist your struggling kidneys.

Plus, we already know that baking soda is good for patients with chronic kidney disease.

Baking soda can even help fight cancer!

Some types of cancerous tumors have an acidic pH, and taking oral supplements of sodium bicarbonate can help raise the pH level of these tumors.

In some types of cancer, this practice can inhibit the tumor’s ability to metastasize (12).

Unhealthy pH levels can also compromise your immune system, which allows your body to be vulnerable to damage from unhealthy organisms that can cause cancer.

Baking Soda as a Natural Remedy

  • Cold and Flu

For hundreds of years, baking soda has been used as a natural treatment for colds and the flu.

As early as 1925, Arm and Hammer, one of the leading manufacturers of baking soda included dosage information for cold treatment on their boxes.

Their recommendations included taking six doses the first day, four the second day, and three the third day, with single doses each day until symptoms disappeared.

Each dose consisted of 1/2 a teaspoon of baking soda in a glass of cool water.

  • Upset Stomach

If you have an upset stomach, the most common dosage is a 1/4 teaspoon of baking soda in a glass of cool water.

This dosage is effective for reducing the acidity of the stomach, which can cause many types of stomach problems.

If you still experience symptoms after trying this method for several days, talk with your doctor, as your problems may not be due to excess stomach acid.



If you ingest baking soda, it’s always best to sip it slowly, rather than gulping it down.

If you drink a tonic of water and baking soda, remember these guidelines:

  • Always make sure the baking soda fully dissolves in the water before drinking it.
  • Never drink more than 3½ teaspoons of baking soda in a single day.
  • If you’re over 60, never take more than 1½ teaspoons in a single day.
  • Never take the maximum dosage of baking soda for longer than two weeks.
  • Always take your time drinking a baking-soda mixture. Never gulp it.
  • Never drink baking-soda mixtures on a full stomach, as it can lead to a gastric rupture.

Generally, it’s non-toxic and safe to apply baking soda on your body, skin, and hair.

But when orally ingesting baking soda, pay attention to maximum doses, and stick to those guidelines.

Because baking soda is high in sodium, it’s not safe at high doses.

Each tablespoon of baking soda has nearly 1,300 milligrams of sodium.

So large doses can cause swelling and increased blood pressure.

If you regularly consume too much baking soda, you can develop heart problems and develop an imbalanced blood chemistry.

Taking too much baking soda also causes your body to excrete potassium, so you could end up with a potassium deficiency if you overuse baking soda for long periods.

This effect could disturb your natural pH balance, which could lead to abdominal pain, nausea, and vomiting.

If you take an extremely excessive amount of baking soda, you could have a seizure, fall into a coma, or even die.

Do not ingest baking soda if you’re pregnant, breastfeeding, or have high blood pressure, kidney disease, liver disease, or edema, or if you’re on a sodium-restricted diet.

If you have any health issue, talk with your doctor about ingesting baking soda.

Specifically, children under six shouldn’t take it without talking to a pediatrician first.

Some prescription medications can interact with baking-soda supplements, so be sure to check with your doctor before taking it if you’re on any prescribed drugs.

Avoid taking baking soda within two hours of taking other types of medicines.

If medical conditions don’t improve after two weeks of baking-soda treatment, stop taking it, and talk with your doctor.



Baking soda is one of nature’s most versatile compounds, and it’s affordable.

As a natural alkaline, baking soda is effective at reducing acid and balancing pH levels.

As a natural remedy, baking soda can help treat upset stomachs, kidney diseases and stones, and skin irritations.

It can also ease sore muscles and help with the symptoms of chemotherapy.

Baking soda can be used to clean your teeth, hair, skin, and nails.

As a cleanser, it’s effective at scrubbing, washing clothes and dishes, removing odors from all kinds of surfaces and places, and boosting the power of many of your existing detergents.

Natural remedies using baking soda include topical treatments, as well as oral supplementation.

If you ingest baking soda, be sure to follow the recommended dosages.

If you have certain medical conditions or take medications, taking too much can be harmful.
