Sodium bicarbonate is a well-known natural remedy for inducing bowel movement.

Here are 3 reasons to use baking soda for constipation:

1. Baking soda eliminates toxic compounds

A buildup of medications, alcohol, and heavy metals obstruct the colon.

Sodium bicarbonate eliminates a wide range of toxic substances from your body, relieving constipation.

2. Baking soda has antifungal properties

Candida albicans is a yeast (a type of single-celled fungus) that lives on the skin and in the mucous membranes of humans.

It can infect the digestive system and form a biofilm that protects it from external factors such as the host immune system and antifungal drugs13.

This biofilm can make stools as hard as cement and therefore hard to pass.

Studies have revealed that sodium bicarbonate has antifungal activity against Candida albicans, helping relieve constipation14,15,16.

3. Baking soda alkalizes your body

Bicarbonate is an essential chemical in the human body. It regulates the acid-base balance by acting as a buffer7.

Studies have shown that supplementation with sodium bicarbonate alkalizes the body, preventing metabolic acidosis17,18,19.

By alkalizing your body, baking soda maintains homeostasis, a steady condition of optimal cell functioning.

This, in turn, stimulates bowel movement by optimizing digestive functions, such as:

  • Digestive enzyme production
  • Peristalsis
  • Intestinal fluid absorption regulation

How to use baking soda for constipation

Here are 3 different ways to use baking soda for constipation:

1. Drink bicarbonate-rich mineral water

Some mineral springs are naturally rich in bicarbonate.

Studies have shown that bicarbonate-alkaline mineral water enhances gastric emptying in the case of constipation20,21.

Mineral water high in bicarbonate contains at least 600 mg of natural sodium bicarbonate per liter22.

The following brands are, for example, rich in bicarbonate:

BrandBicarbonate [mg/l]
Vichy Celestins2989

The bicarbonate content of bottled mineral water is usually mentioned on the bottle label.


Drink a glass of mineral water high in bicarbonate first thing in the morning, at least an hour before breakfast.

2. Use baking soda powder

Another way to take baking soda for constipation is to drink a glass of water mixed with sodium bicarbonate powder.

It is noteworthy that too much baking soda powder will not relieve constipation. On the contrary, it will have the opposite effect.

3. Take a baking soda detox bath

You can also relieve constipation by soaking in a warm bath to which you have added sodium bicarbonate.

When you are soaking in the tub, it is almost the whole surface of your skin that is in contact with the baking soda-water mixture.

Epsom salt (magnesium sulfate) bath for a Herxheimer reaction.

Your skin will absorb the alkaline salt and release the toxins through your pores when you sweat, relieving constipation.


Take a bath to which you have added a teaspoon of sodium bicarbonate.

Soak for at least 20 minutes in the tub.
