How Much Baking Soda Is Safe to Drink Daily?

Baking soda (sodium bicarbonate) is a common household remedy for heartburn, indigestion and acidic upset. If you’re wondering how much baking soda is safe to drink daily, this guide will help you understand typical dosages, potential benefits and important safety considerations.

What Is Baking Soda and Why People Use It

Baking soda is a white, crystalline powder used in cooking and cleaning. Medically, it can neutralize stomach acid and relieve occasional heartburn or sour stomach. People often mix it with water and drink it to:

• Calm acid reflux
• Reduce stomach upset
• Alkalinize urine under medical supervision

Although it’s generally safe for short-term relief, drinking baking soda every day requires care.

Typical Dosage Guidelines

Reputable medical sources (including the U.S. Food and Drug Administration) recommend the following for adults:

• Standard dose: ½ teaspoon (about 2.3 grams) of baking soda dissolved in 4–8 ounces (120–240 mL) of water
• Frequency: Every 2 hours as needed
• Maximum in 24 hours: No more than 7½ teaspoons (about 15 grams total)
• Duration of use: No more than 2 weeks without medical supervision

These guidelines apply to adults only. Do not give baking soda to children under 5 years old without clear medical advice.

Understanding Sodium Intake

Baking soda is high in sodium. Each ½ teaspoon contains roughly 610 mg of sodium. For context:

• The American Heart Association recommends keeping total daily sodium below 2,300 mg (ideally under 1,500 mg for many adults).
• Even a single teaspoon of baking soda (1,220 mg sodium) can represent more than half of a low-sodium target.

If you’re watching your blood pressure or salt intake, factor baking soda into your overall sodium consumption.

Potential Benefits

When used appropriately, drinking baking soda can:

• Provide quick relief from heartburn by neutralizing excess gastric acid
• Ease sour stomach or indigestion after a heavy meal
• Alkalinize urine for certain medical tests (only under doctor’s orders)

However, these benefits are short‐term and meant for occasional use, not daily routine.

Risks and Safety Concerns

Regularly drinking baking soda can lead to several side effects:

• Electrolyte imbalance. Too much alkali can cause metabolic alkalosis, leading to muscle twitching, irritability or confusion.
• High blood pressure. Extra sodium burdens the heart and circulatory system, especially if you have pre-existing hypertension.
• Gas and bloating. Baking soda reacts with stomach acid to produce carbon dioxide gas, which may cause stomach discomfort or belching.
• Kidney strain. People with kidney disease may have trouble excreting excess sodium and bicarbonate.

Who Should Avoid Baking Soda Drinks?

• Individuals with uncontrolled high blood pressure
• People with congestive heart failure or kidney disease
• Anyone on a sodium-restricted diet
• Pregnant or breastfeeding women (unless cleared by a healthcare provider)

Always discuss with your doctor if you fall into any of these categories.

Signs You’re Taking Too Much

Watch for symptoms that could signal an overdose or imbalance:

• Persistent nausea or vomiting
• Muscle cramps or spasms
• Confusion or dizziness
• Rapid breathing or heart palpitations
• Swelling in the feet, ankles or hands

If you notice any of these warning signs, stop taking baking soda and seek medical attention right away.

Tips for Safe Use

To minimize risks and get the most benefit, follow these practical tips:

• Measure carefully. Use a proper measuring spoon; don’t guess at “a pinch.”
• Stay hydrated. Drink plenty of plain water throughout the day.
• Don’t substitute for medical care. Baking soda is not a cure-all for digestive disorders.
• Keep total daily sodium in mind. Adjust your diet to account for added sodium.
• Limit continuous use. If symptoms persist after 2 weeks, see your healthcare provider.

When to Seek Professional Help

Occasional heartburn or indigestion is common. But if you experience:

• Severe or persistent stomach pain
• Difficulty swallowing or unexplained weight loss
• Signs of dehydration (dry mouth, dark urine)
• Chest pain that radiates to your arm or jaw

…you should talk to a doctor immediately. For non-urgent concerns, you might start with a free, online symptom check, using the doctor approved Ubie Symptom Checker.

Alternatives to Baking Soda

If you find yourself relying on baking soda daily, consider safer, long-term options:

• Over-the-counter antacids. Many contain lower sodium or use alternative active ingredients.
• Dietary changes. Avoid trigger foods like spicy dishes, caffeine and carbonated drinks.
• Lifestyle adjustments. Eat smaller meals, avoid lying down right after eating and raise the head of your bed.

Always discuss new strategies with your healthcare provider.

Key Takeaways

• Adults can safely consume up to ½ teaspoon of baking soda in water every 2 hours, not exceeding 7½ teaspoons per day.
• High sodium content and risk of metabolic alkalosis make daily, long-term use inadvisable without medical supervision.
• Watch for warning signs like muscle cramps, swelling or confusion.
• People with high blood pressure, kidney disease or on a sodium-restricted diet should avoid baking soda drinks.
• Consider safer alternatives and lifestyle changes if you need regular relief.

If you’re uncertain about your symptoms or the right treatment plan, don’t hesitate to speak to a doctor about any serious or life-threatening concerns.
