Recent scientific research has suggested that drinking baking soda (sodium bicarbonate) might help combat autoimmune diseases by influencing the body’s immune response.
This inexpensive and widely available compound could potentially reduce inflammation and promote an anti-inflammatory environment in the body. Here’s a breakdown of how it works, its potential benefits, and important considerations:

How Baking Soda May Help Autoimmune Diseases
- Promotes an Anti-Inflammatory Response
- When consumed, baking soda signals the spleen (a key organ in the immune system) to shift from a pro-inflammatory state to an anti-inflammatory one.
- It does this by affecting macrophages, a type of white blood cell. Macrophages can either promote inflammation (M1 type) or suppress it (M2 type). Baking soda encourages the M2 anti-inflammatory response.
- Alkalizes the Body
- Baking soda is mildly alkaline and helps neutralize excess acidity in the body. Chronic inflammation often correlates with an acidic internal environment, so restoring pH balance may alleviate symptoms.
- Regulates the Immune System
- Autoimmune diseases occur when the immune system mistakenly attacks healthy tissues. Baking soda appears to “reprogram” certain immune cells, reducing their tendency to attack the body’s own cells.
- Affects Interleukins
- Baking soda increases the production of anti-inflammatory cytokines (like IL-10) while decreasing pro-inflammatory ones (like IL-6), helping to calm the immune system.
The Science Behind It
A 2018 study published in the Journal of Immunology found that drinking a baking soda solution:
- Changed the behavior of mesothelial cells, which line internal organs, signaling the spleen to reduce inflammation.
- Encouraged the conversion of pro-inflammatory immune cells into anti-inflammatory ones.
- Showed promise in reducing symptoms in conditions like rheumatoid arthritis and chronic kidney disease.
How to Use Baking Soda for Autoimmune Conditions
- Dosage Guidelines
- Start with 1/4 teaspoon of baking soda mixed in 8 ounces of water once daily.
- Gradually increase to 1/2 teaspoon per day if tolerated, but do not exceed this amount unless advised by a healthcare provider.
- Best taken on an empty stomach, preferably first thing in the morning or at least 2 hours after eating.
- Consistency is Key
- The effects of baking soda are cumulative, meaning regular use over time may yield better results than sporadic consumption.
Potential Benefits
- Reduced Inflammation : Helps manage symptoms of inflammatory autoimmune diseases such as lupus, rheumatoid arthritis, and Crohn’s disease.
- Improved Kidney Function : Shown to slow the progression of chronic kidney disease by reducing acidity in the kidneys.
- Cost-Effective : Baking soda is inexpensive and readily available, making it accessible for long-term use.
Conclusion
Drinking baking soda shows promise as a simple, affordable way to support the management of autoimmune diseases by promoting an anti-inflammatory state in the body. However, it’s crucial to approach this remedy cautiously and under professional supervision. Combined with a balanced diet, regular exercise, and stress management, baking soda could be a valuable tool in your holistic health toolkit.
