What is baking soda?

Baking soda is mined in many places like California, Colorado, Mexico, and Uganda for its ore called Nahcolite. It is made entirely of sodium bicarbonate (NaHCO3) which has an alkaline nature (pH 9) and is responsible for most of the properties of baking soda utilized by us.

It is commonly used to bake bread because on reacting with an acid, it gives off CO2 gas which makes the bread spongy. Baking powder, on the other hand, contains a mixture of sodium bicarbonate and a weak acid.

Use of baking soda in teeth and hair

1. Toothpaste

According to an article published in the Journal of Clinical Dentistry, adding baking soda to your toothpaste enhances plaque removal dramatically and promotes better dental hygiene. (1)

You can either make your own toothpaste at home or add baking soda to store-bought toothpaste and use it a few times a week.

Since baking soda is an abrasive, using it alone for a long time can cause attrition, i.e., wearing off of enamel. So, make sure you dilute it in your paste or soak your brush in a mixture of baking soda and water before use.

14. Along with cancer drugs

Cancer drugs being weakly alkaline in nature cannot act effectively in the acidic pH of many solid tumors. Also, the low pH diminishes your immune response and helps pathogens to flourish.

17. Car wash

Add one-fourth cup of baking soda to one cup water and dissolve it well before rubbing it on your car’s seats, windows, tires, and lights to remove dirt and grease effectively.

For all the other ‘paint-covered’ parts, dilute one-fourth NaHCO3 powder in a gallon of water and make sure no lumps are left behind as the powder itself is an abrasive.

Health benefits of baking soda

1.  Acts as an antacid for stomach pain

Being alkaline, baking soda neutralizes the acid being produced in the stomach. Most of the times, stomach pain occurs due to an unopposed release of gastric acid (HCl) and acid reflux or heartburn.

This can lead to ulcer formation which has dire consequences in the form of bleeding and perforation. Increased consumption of acidic foods or a generalized acidic state may aggravate such conditions.

Add a teaspoon of baking soda to a cup of water, mix it well, and drink it slowly to get instant relief. It not only neutralizes your stomach acid but also brings your body’s altered pH back to normal. (4)

2. Alleviates symptoms of urinary tract infection

Urinary tract infection is one of the most common diseases in the US which comes with a lot of disturbing symptoms like burning sensation while urinating, incontinence and increased frequency of micturition. (5)

A 2017 study published in the International Urogynecological Journal gave oral sodium bicarbonate supplements to women suffering from lower urinary tract infection who had a urine pH of less than 6.

After four weeks, the subjects who received oral bicarbonates showed higher urine pH and improved symptoms of UTI like nocturia (increased urination at night), burning micturition, incontinence, and increased frequency. (6)

Hence, baking soda is an inexpensive and effective way of alleviating the symptoms of UTI with the added advantage of minimal side effects associated with it.

3. Kills pathogenic bacteria and fungi

Bacteria like Streptococcus mutans are one of the leading causes of tooth decay and dental caries. Adding baking soda to your toothpaste or gargle prevents the growth of this bacterium in addition to keeping bad odor away. (7)

Baking soda can effectively kill many fungal groups like dermatophytes, candida, and molds that cause nail and skin infections along with other superficial skin conditions. (8)

4. Improves kidney health

Baking soda intake alleviates the degree of metabolic acidosis which is produced as a result of chronic kidney disease. Some researchers postulate that metabolic acidosis may also aggravate the ongoing kidney damage.

A clinical study on 134 patients of chronic kidney disease published in the Journal of the American Society of Nephrology showed that bicarbonate supplementation significantly reduced the progression of chronic kidney disease while improving the nutritional status.

The number of patients who developed the end-stage renal disease (ESRD) was lower as compared to the control group. (9)

5. Increases the efficacy of anti-cancer medications

Since cancer cells in the center of large tumors don’t get enough oxygen, lactic acid production increases (by anaerobic respiration) and consequently, cells enter a quiescent stage.

Baking soda neutralizes the acidified pH and restores cell replication. As a result, bicarbonate adjuvant improves the efficacy of anti-cancer drugs which primarily target actively replicating cells. (10)

Prolonged chemotherapy comes with many side effects, mouth and throat changes being one of the most common. To prevent this, you can rinse your mouth thrice daily with a mixture of ¼ teaspoon baking soda and 1/8 teaspoon common salt in one cup of warm water followed by a rinse with plain water. (11)

6. Prevents muscular cramps and early fatigue

During prolonged and strenuous exercises, the increased oxygen demand of skeletal muscles is not met by their blood supply. Hence, they switch to anaerobic respiration resulting in high levels of lactic acid.

Low pH and increased organic acids denature proteins and also hinder metabolic reactions. Consequently, we experience fatigue and muscle cramps.

Baking soda alkalinizes the tissue pH, therefore, preventing the adverse effects of high acidity on muscles leading to better training outcome in the long run. (12)

A 2013 research article on the impact of bicarbonate loading and sports performance point out that taking baking soda before exercise improves athletic performance concerning the first one to seven minutes of strenuous exercise and prolonged physical activity with the intermittent high-intensity workout. (13)


7. Minimizes the symptoms of rheumatoid arthritis

Rheumatoid arthritis is an autoimmune condition where you experience multiple joint pain, joint stiffening, and immobility. This occurs due to the body’s immune cells destroying self-tissue.

Sodium bicarbonate, by some neurochemical process, enhances the production of anti-inflammatory cells (M2 macrophages) as opposed to the damaging M1 macrophages.

Hence, destruction of joint tissues reduces greatly, and your symptoms improve. (14) Thus, you can get a cheap, homemade, and most importantly, effective treatment for your joint pains and other inflammatory conditions.

Precautions while using baking soda

Although baking soda is safe and non-toxic as compared to its contemporaries, its daily intake or ingesting a hefty dose of sodium bicarbonate comes with some repercussions.

  • Nausea, vomiting, diarrhea, abdominal pain
  • Bloating due to CO2 production
  • Hypertension and fluid retention (edema) leading to heart failure in chronic cases due to an elevation of sodium levels
  • Early fatigue and heart arrhythmia as a consequence of falling potassium levels
  • Pregnant and lactating women along with kids less than six years must refrain from bicarbonate intake
  • If you’re currently on certain medications like aspirin, barbiturates, calcium channel blockers, and steroids then, you must first consult your doctor before taking any baking soda preparations.

Points to take home

Baking soda has multiple uses in healthcare, beauty products, and home decor. From alleviating to your troublesome stomach pain and increasing your exercise tolerance to slowing down the spread of your cancer, sodium bicarbonate is resourceful in all aspects of healthcare.

It is added in many skin care products, toothpaste, shampoos, and even creams for bug bites. It also acts as a deodorant, has anti-inflammatory activity, removes dirt and grime from utensils, and is used as a hand softener as well.

So, next time you walk past an aisle of this seemingly unimportant white powder, take a pause, recollect this article, and make sure you test all the uses of baking soda mentioned here.
