Is Baking Soda Good for Diabetes? Benefits & Risks Explained
Is Baking Soda Good for Diabetes? Benefits, Risks, and What Science Really Says
The internet is full of home remedies, natural cures, and do-it-yourself health hacks.
Among these, baking soda (sodium bicarbonate) frequently pops up as a supposed miracle ingredient for everything from whitening teeth to soothing acid reflux.
But a growing number of people with diabetes are asking: “Is baking soda good for diabetes?”
It’s complicated. While baking soda may offer potential benefits for certain diabetes-related complications, it’s not a treatment or cure for the disease itself.
This article explores the science, the speculation, and the safety concerns around using baking soda in the context of diabetes.
Whether you’re managing Type 1, Type 2, or prediabetes, understanding what works and what doesn’t is critical to protecting your long-term health.
What Is Baking Soda?
Baking soda is a white crystalline powder with the chemical formula NaHCO₃. It’s a mildly alkaline compound that reacts with acids to produce carbon dioxide gas.
This gas-producing property is what makes it so useful in cooking (hello, fluffy pancakes!) and in over-the-counter antacid treatments.
Common Uses Include:
- Neutralizing stomach acid (heartburn remedy)
- Baking leavening agent
- Mild cleaning and deodorizing
- Oral health (toothpaste ingredient
- Occasional medical treatments for acidosis
But does this pantry staple really have a place in managing a complex chronic condition like diabetes?
Understanding Diabetes: A Brief Overview
Before diving into baking soda’s role, it’s important to understand what diabetes is:
- Type 1 Diabetes: An autoimmune disease where the pancreas produces little or no insulin.
- Type 2 Diabetes: Characterized by insulin resistance, often linked to diet, lifestyle, and genetics.
- Prediabetes: Blood sugar levels are higher than normal but not yet high enough to be classified as Type 2 diabetes.
Diabetes affects multiple body systems, including blood vessels, nerves, kidneys, and the immune system. Management focuses on blood sugar control, weight management, cardiovascular health, and preventing complications.
The Claim: Can Baking Soda Help Manage Diabetes?
Let’s break this down into three key questions:
- Does baking soda lower blood sugar?
- Can it help with diabetes-related complications (like kidney issues or infections)?
- Is it safe to use regularly if you have diabetes?
Let’s explore the evidence.
Does Baking Soda Lower Blood Sugar?
The Reality: No, Baking Soda Does Not Directly Lower Blood Glucose
Despite some online claims, there’s no reliable scientific evidence that baking soda can lower blood sugar or improve insulin sensitivity.
While some animal studies and isolated in vitro experiments show minor metabolic shifts, these findings do not translate into real-world, human clinical benefits for managing blood glucose.
The Studies:
A study published in the journal Kidney International (2010) investigated whether correcting metabolic acidosis with sodium bicarbonate improved insulin resistance in patients with chronic kidney disease (CKD).
While there was a modest improvement in insulin sensitivity, this effect was indirect and only observed in people with CKD not in healthy individuals or people with early-stage diabetes.
Conclusion: Baking soda does not lower blood sugar and should not be used in place of medications or lifestyle interventions for diabetes.
The Science: Baking Soda and Diabetic Complications
Although baking soda doesn’t lower glucose levels, it may indirectly benefit people with diabetes by addressing certain complications, especially those affecting the kidneys and the immune system.
1. Kidney Disease (Diabetic Nephropathy)
Diabetic nephropathy is one of the most common long-term complications of diabetes. High blood sugar levels damage the blood vessels in the kidneys, leading to poor filtration and, eventually, kidney failure.
One of the early signs of kidney dysfunction is metabolic acidosis, a condition where the body becomes too acidic. This is where baking soda can help.
Studies Support:
- A 2009 clinical trial from the Journal of the American Society of Nephrology found that sodium bicarbonate slowed the progression of CKD and improved nutritional status in patients with metabolic acidosis.
- Patients taking baking soda had lower rates of dialysis initiation and fewer hospitalizations.
However: This benefit is seen only in patients with advanced kidney disease and should be done under medical supervision.
2. Immune System and Infections
Another concern for people with diabetes is increased susceptibility to infections, including rare fungal infections like mucormycosis, especially during diabetic ketoacidosis (DKA).
DKA is a medical emergency characterized by acid buildup in the blood. During this condition, baking soda has been used medically to correct severe acidosis and reduce fungal growth in lab models.
However, its use is controversial because:
- It may worsen ketone production in some cases.
- It’s not effective unless the patient has severe acidosis (blood pH < 7.0).
Conclusion: Baking soda may be used in a hospital setting for DKA or infection control but is not suitable for at-home use in these cases.
What Are the Risks of Using Baking Soda in Diabetes?
While baking soda might sound harmless, regular or unsupervised use can come with significant risks especially for people with diabetes.
1. High Sodium Intake
Baking soda contains sodium, which can:
- Raise blood pressure
- Worsen heart disease
- Exacerbate kidney damage
Even a small amount (½ teaspoon) contains around 600 mg of sodium. Diabetics are already at higher risk for heart and kidney complications, so this sodium load can be dangerous.
2. Metabolic Alkalosis
Taking too much baking soda can lead to alkalosis, a dangerous shift in the body’s pH balance. Symptoms include:
- Nausea
- Vomitin
- Muscle twitching
- Confusion
- Heart rhythm abnormalities
3. Drug Interactions
Sodium bicarbonate can interact with several common medications, including:
- Diabetes drugs like metformin
- Antibiotics like tetracyclines
- Aspirin
- Blood pressure medications
It may also affect how drugs are absorbed in the stomach due to pH changes.
Who Might Benefit from Baking Soda?
So, is there any group of diabetics who might safely use baking soda under certain circumstances?
Possibly Helpful If:
- You have chronic kidney disease (stages 3–5)
- Your bicarbonate level is low (< 22 mEq/L)
- You are under medical supervision
- You need to correct metabolic acidosis
Not Recommended If:
- You have normal kidney function
- You’re using it to control blood sugar
- You have high blood pressure
- You are prone to fluid retention or heart failure
Always speak with your healthcare provider before starting any supplement or natural remedy especially one like sodium bicarbonate that can significantly affect your body’s electrolyte and acid-base balance.
How to Safely Use Baking Soda (If Medically Advised)
If your doctor determines that you might benefit from baking soda therapy, here’s what a typical regimen might look like:
Typical Dose:
- ½ teaspoon (approx. 3 grams) dissolved in a glass of water
- 1–2 times daily, depending on your bicarbonate levels
Monitoring:
- Regular blood tests (sodium, potassium, bicarbonate, kidney function)
- Blood pressure checks
- Urinalysis
Never self-dose with baking soda for extended periods without medical advice.
Natural Alternatives to Baking Soda for Diabetes Support
If you’re looking for natural ways to support your diabetes care, here are some safer alternatives to baking soda:
- Apple Cider Vinegar: Some studies show it may slightly improve insulin sensitivity and reduce post-meal glucose spikes.
- Fiber-Rich Foods: Soluble fiber (from oats, legumes, fruits) can slow glucose absorption and improve cholesterol.
- Magnesium-Rich Foods: Magnesium may help regulate blood sugar and reduce insulin resistance.
- Physical Activity: Exercise remains one of the most effective “natural” ways to lower blood sugar and reduce insulin resistance.
Advanced Considerations: Baking Soda in Functional and Integrative Medicine
In the world of functional medicine, practitioners often explore non-conventional uses of familiar substances, including baking soda.
The approach typically involves looking at the body’s biochemistry as a whole, rather than treating isolated symptoms.
While this can open the door to more holistic insights, it’s crucial to distinguish between evidence-based practices and speculative interventions.
Potential Integrative Uses (Under Expert Supervision):
- Urine pH modulation: Some integrative practitioners attempt to alkalize the body by adjusting urine pH. However, the body naturally regulates blood pH tightly, and trying to shift it externally can be risky and counterproductive.
- Anti-inflammatory effects: Emerging animal studies suggest baking soda may impact inflammation and immune response via the spleen and vagus nerve. But this remains preclinical, and its relevance to diabetes is uncertain.
Functional medicine may experiment with baking soda as part of broader detox or pH strategies but the data for diabetes support is not there yet.
The Marketing Perspective: Why the Baking Soda Trend Caught On
It’s worth examining why so many people, even those with diabetes, have latched onto the idea of baking soda as a potential cure or supplement.
The Psychology Behind It:
- Low cost: Baking soda is cheap and accessible.
- “Natural” appeal: People equate “natural” with safe or superior.
- Desperation: Many are frustrated with conventional care and looking for control or alternatives.
- Echo chambers: Online influencers, unverified YouTubers, and alternative health blogs often amplify untested claims.
This is where patient education becomes vital. Misinformation, even when well-intentioned, can lead to delays in proper care and serious complications.

Frequently Asked Questions (FAQs)
Can I take baking soda every day if I have diabetes?
- Only if prescribed by your doctor for a specific condition like metabolic acidosis. It is not a general supplement for diabetes.
Does baking soda cure diabetes?
- No. There is no cure for diabetes. Baking soda does not affect insulin production or blood glucose control.
Is it safe to use baking soda for acid reflux if I have diabetes?
- Occasionally, yes. But frequent use is not recommended due to sodium content. Consider other antacid options.
Can I mix baking soda with apple cider vinegar for diabetes?
- This is a common online trend, but there’s no scientific backing and the combo may cause gas, bloating, and interact with medications.
What Actually Works to Manage Diabetes?
Effectively managing diabetes requires a holistic, evidence-based strategy that includes:
- A balanced, nutrient-rich diet (with low glycemic impact)
- Regular physical activity
- Consistent blood glucose monitoring
- Proper use of medications or insulin (as prescribed)
- Weight management and stress reduction
- Routine checkups and lab evaluations
These interventions are proven to reduce complications, improve quality of life, and help maintain stable blood sugar levels over time.
Conclusion
The idea of using baking soda to manage diabetes has gained popularity online, but it’s crucial to separate fact from fiction.
While baking soda (sodium bicarbonate) does have specific, medically approved uses such as treating metabolic acidosis in chronic kidney disease or in controlled hospital settings for diabetic ketoacidosis it is not a cure, treatment, or blood sugar control agent for diabetes.
Despite anecdotal reports and viral health claims, there is no credible clinical evidence that baking soda can lower blood glucose, enhance insulin sensitivity, or reverse diabetes in any form.
Moreover, the unsupervised use of baking soda can pose health risks, particularly for individuals with:
- High blood pressure
- Heart conditions
- Kidney disease
This is largely due to its high sodium content and its ability to disrupt the body’s acid-base balance, which is finely regulated and essential for metabolic health.
