What Is Baking Soda and How Does It Work?
Baking soda, chemically known as sodium bicarbonate (NaHCO₃), is an alkaline salt often used in baking and cleaning. Ingesting it mixed with water can temporarily neutralize excess acidity. In the stomach, this reaction reduces heartburn and indigestion. For athletes, the increase in blood bicarbonate levels can buffer lactic acid buildup in muscles during intense, anaerobic exercise, delaying fatigue and potentially improving performance. However, the body's pH balance is tightly regulated, and external factors like ingesting large amounts of baking soda can disrupt this delicate equilibrium, leading to health issues.
Potential Benefits of a Morning Baking Soda Drink
Temporary Relief for Heartburn and Indigestion
One of the most well-documented benefits of drinking a small amount of baking soda in water is its ability to provide quick, temporary relief from indigestion and heartburn. The alkaline properties neutralize stomach acid, which can soothe the burning sensation caused by acid reflux. A typical remedy involves dissolving about half a teaspoon of baking soda in at least half a cup of cold water. It is crucial to remember that this is a short-term solution and should not be used for more than two weeks without consulting a doctor.
Potential Boost for Athletic Performance
For high-intensity training, some athletes use sodium bicarbonate as an ergogenic aid. During intense exercise, muscles produce lactic acid and hydrogen ions, which can lead to muscle fatigue and a drop in performance. Sodium bicarbonate acts as a buffer, helping to remove excess hydrogen ions from the muscles and delaying the onset of fatigue. Studies have shown that it may improve performance in activities lasting between 1 and 7 minutes, such as sprinting, swimming, and rowing. The optimal dosage is often around 0.3 grams per kilogram of body weight, taken 60-180 minutes before exercise. It is not beneficial for muscle strength, and due to potential gastrointestinal distress, professional supervision is recommended.
Supportive Role in Chronic Kidney Disease (CKD)
In medically supervised contexts, sodium bicarbonate can be prescribed to patients with chronic kidney disease (CKD) who suffer from metabolic acidosis. Healthy kidneys regulate the body's acid-base balance, but in CKD, this function is impaired, causing an acid buildup. By providing a base, sodium bicarbonate can help normalize blood pH and has been shown to potentially slow CKD progression and improve nutritional markers in some patients. This is a clinical treatment, and self-medicating is strongly discouraged.
Significant Risks and Cautions
Despite the perceived benefits, drinking baking soda, especially in the morning on an empty stomach, carries substantial risks. The high sodium content is a major concern.
Health Risks of Regular or Excessive Consumption
- High Sodium Intake: A single teaspoon of baking soda contains about 1,200 mg of sodium. Exceeding the recommended daily intake can cause serious problems, especially for those with high blood pressure, heart disease, or kidney conditions.
- Metabolic Alkalosis: Long-term or excessive use can lead to metabolic alkalosis, where the body's pH becomes too alkaline. This condition can cause severe electrolyte imbalances, confusion, and muscle issues.
- Gastric Rupture: Though rare, a rapid chemical reaction between baking soda and stomach acid can produce a large amount of gas, potentially leading to stomach rupture, particularly after a large meal.
- Nutrient Absorption: Frequent ingestion can alter stomach pH levels, which can interfere with the proper absorption of nutrients.
- Medication Interference: Baking soda can affect how the body absorbs other medications. It is important not to take it within two hours of other medications.
Baking Soda vs. Over-the-Counter (OTC) Antacids
| Feature | Baking Soda (DIY) | OTC Antacids (e.g., Tums, Mylanta) | 
|---|---|---|
| Effectiveness for Indigestion | Provides rapid, but temporary relief by neutralizing stomach acid. | Provides fast, temporary relief; formulations are standardized and proven effective. | 
| Risks | High sodium content can lead to hypertension, fluid retention, and metabolic alkalosis with regular use. | Lower risk of overdose compared to DIY solutions; specific types may have different side effects. | 
| Dosage Control | Dosing can be imprecise, increasing risk of side effects if too much is consumed. | Come in standardized doses (e.g., tablets), making dosage more controlled and safer. | 
| Long-Term Use | Not recommended for long-term use without medical supervision. | Many are safe for short-term use, but prolonged use requires medical consultation. | 
| Cost | Generally cheaper than OTC alternatives. | Can be more expensive, but often more reliable and safer for self-treatment. | 
Proper Protocol and Safety Precautions
If you are considering trying baking soda for short-term relief, follow these guidelines:
- Consult a Professional: Always speak with a healthcare provider before starting any new regimen, especially if you have pre-existing conditions like kidney disease, heart disease, or high blood pressure, or are pregnant.
- Use Correct Dosage: For temporary indigestion relief, dissolve no more than half a teaspoon of baking soda in at least 4 ounces (half a cup) of cold water. Drink it slowly.
- Monitor Your Intake: Do not use baking soda as a daily habit or for more than two weeks straight unless advised by a doctor.
- Avoid Certain Combinations: Don't take it within two hours of other medications. Never take baking soda after a large meal, as this can increase the risk of gastric rupture.
Conclusion
Drinking baking soda in the morning, or at any time, offers a few specific, and primarily temporary, benefits such as relieving indigestion and buffering muscle acidity during intense exercise. For chronic conditions like kidney disease, it can only be used under strict medical supervision. However, these limited benefits must be weighed against significant risks, including dangerously high sodium intake, potential metabolic alkalosis, and medication interference. Given the availability of safer, more controlled over-the-counter options for common ailments like heartburn, most health professionals advise against using baking soda as a regular self-medication. The high risks and lack of evidence for broader wellness claims, like weight loss or general inflammation reduction, make it a questionable choice for routine consumption. Always prioritize caution and seek advice from a medical professional before starting this practice.
