Sodium bicarbonate, commonly known as baking soda, is much more than a kitchen staple. It has a variety of health benefits that many people overlook. It can help with digestion, reduce acid in the body, improve oral health, and even support kidney function.
Besides these health uses, sodium bicarbonate works as a natural cleaner and has antibacterial and anti-inflammatory properties. These qualities make it useful for skin care, reducing inflammation, and treating minor infections. Its versatility in both health and household tasks makes it a valuable product to know about.
People often associate baking soda with baking or cleaning, but its ability to neutralise acids and balance pH levels means it can offer real health benefits when used correctly. This simple compound plays a role in managing conditions like heartburn and may also help with athletic performance by reducing muscle fatigue.
Core Health Benefits of Sodium Bicarbonate
Sodium bicarbonate affects the body in several important ways. It helps balance acidity, supports kidney function, reduces heartburn, and may improve physical performance during exercise.
Alkalising Effects on the Body
Sodium bicarbonate acts as a natural alkaline substance. When it dissolves in water, it produces bicarbonate ions that neutralise excess acid in the bloodstream. This helps maintain the body’s pH balance, which is vital for normal cellular function.
By reducing acidity, it can prevent conditions linked to high acid levels, such as acid reflux and metabolic acidosis. People with diets high in acid-forming foods may benefit from this effect. However, the body usually regulates pH well on its own, so sodium bicarbonate is best used carefully and not for long periods without medical advice.
Support for Kidney Health
Kidneys regulate acid levels in the body by removing excess hydrogen ions. Sodium bicarbonate helps lessen the load on kidneys by neutralising acid in the blood. This can slow down the progression of chronic kidney disease (CKD) by reducing acid-related damage to kidney tissue.
In some cases, doctors recommend sodium bicarbonate to patients with CKD to help maintain a safer acid-base balance. It may also improve overall kidney function and help reduce symptoms linked to kidney problems. Careful dosing and monitoring by a healthcare professional is important.
Role in Antacid Relief
Sodium bicarbonate is widely used as an antacid to relieve indigestion and heartburn. It directly neutralises stomach acid, reducing irritation and discomfort in the oesophagus and stomach lining.
This effect begins quickly, often within minutes after ingestion, making it useful for short-term relief. It is generally safe when used occasionally and at recommended doses. However, excessive or long-term use can cause side effects like increased blood pressure or imbalances in mineral levels.
Improvement in Physical Performance
During intense exercise, muscles produce lactic acid, which can cause fatigue and decrease performance. Sodium bicarbonate may help by buffering this acid build-up in the muscles.
Taking it before exercise can delay muscle fatigue and improve endurance by maintaining a more stable pH level in muscle cells. This can be particularly beneficial for high-intensity or sprint activities. However, it may cause side effects such as stomach discomfort, so individuals should test tolerance and consult professionals before use.
Daily and Practical Applications
Sodium bicarbonate is commonly found in many homes due to its useful and varied applications. It plays a role in maintaining oral hygiene, improving cleaning routines, and enhancing food preparation.
Oral Health and Dental Care
Sodium bicarbonate is often used to improve oral health. It can neutralise acids in the mouth, reducing the risk of tooth decay and helping with bad breath.
Many people brush their teeth with baking soda or use it as an ingredient in homemade toothpaste. Its mild abrasive quality helps remove plaque and surface stains gently without damaging enamel.
It can also be mixed with water to create a mouthwash that kills bacteria. This helps reduce gum inflammation and promotes overall dental hygiene.
Enhancing Cleaning and Odour Control
Sodium bicarbonate is a popular, eco-friendly cleaner. It dissolves in water, gently lifting dirt and grime from surfaces without harsh chemicals.
It is excellent for removing stains in kitchens and bathrooms. It can also be sprinkled on carpets or upholstery to absorb and neutralise unpleasant odours.
Its deodorising effect makes it ideal for use in fridges and rubbish bins. Users often place an open box in these areas to keep smells under control naturally.
Use in Food Preparation
In cooking, sodium bicarbonate acts as a leavening agent. It reacts with acids in recipes to produce carbon dioxide gas, which makes dough and batter rise.
It is commonly added to cakes, bread, and biscuits to improve texture and lightness. Its alkaline nature also helps soften vegetables during cooking.
In some cases, it is used to neutralise acidic ingredients or to tenderise meat gently. However, correct amounts are important to avoid altering flavour.

Considerations and Cautions
Sodium bicarbonate is useful but should be handled carefully. Its side effects, correct dosage, and possible interactions with other medicines are important to understand before use.
Potential Side Effects
Sodium bicarbonate may cause mild side effects like gas, stomach cramps, or increased thirst. If taken in large amounts, it can lead to more serious problems such as metabolic alkalosis—a condition where the body’s pH becomes too alkaline.
Some individuals might experience allergic reactions, including rash or swelling. Individuals with high blood pressure or kidney disease should exercise particular caution, as sodium bicarbonate can increase sodium levels and disrupt electrolyte balance.
Overuse can disrupt mineral balance and cause symptoms like muscle spasms or irregular heartbeat. Monitoring intake and watching for unusual symptoms is important.
Safe Dosage Guidelines
The proper dose of sodium bicarbonate varies based on the reason for use and individual health factors. For heartburn relief, doses typically range from 1/2 to 1 teaspoon in water every 2 hours, not exceeding 7 doses in a 24-hour period.
Using too much can cause serious health problems, so following package instructions or a healthcare provider’s advice is essential. It should not be used continuously for more than two weeks without medical supervision.
People should avoid taking sodium bicarbonate close to meals or activities unless advised, as timing can affect its effectiveness and safety.
Interactions with Medications
Sodium bicarbonate can change how some drugs work by altering stomach acidity or the body’s pH. For example, it may reduce the absorption of certain antifungal or antibiotic medications like ketoconazole or tetracycline.
It can also interact with lithium, aspirin, and blood pressure medicines, potentially altering their effects. These interactions can increase side effects or reduce drug efficiency.
Always consult a healthcare professional before combining sodium bicarbonate with other treatments to avoid harmful effects or reduced medication effectiveness.
