Baking soda has long been used for everyday remedies, from easing heartburn and whitening teeth to acting as a natural deodorant. More recently, researchers have explored whether it may also help reduce inflammation linked to autoimmune diseases. Autoimmune conditions occur when the immune system mistakenly attacks the body’s own tissues, contributing to chronic inflammation and conditions such as rheumatoid arthritis, lupus, multiple sclerosis, psoriasis, and Hashimoto’s thyroiditis.

A 2018 study published in The Journal of Immunology examined the effects of drinking water mixed with baking soda. Researchers found that it appeared to encourage anti-inflammatory activity within the body. According to the study, immune cells known as macrophages shifted from inflammation-promoting types to inflammation-reducing types. Scientists believe this process may involve signals that help regulate the body’s immune response and reduce excessive inflammation.

For those interested in trying it, a commonly suggested mixture is 1/2 teaspoon of baking soda dissolved in two cups of water, consumed once daily. Supporters believe this simple drink may help encourage the body’s natural anti-inflammatory pathways. However, it should be viewed as a supportive measure rather than a treatment or cure for autoimmune diseases or other chronic conditions.

While baking soda is inexpensive and widely available, it should be used with caution. Its high sodium content may not be suitable for people with high blood pressure, kidney problems, or those on sodium-restricted diets. It can also interact with certain medications and may cause mild side effects such as bloating or nausea. Anyone considering regular use should speak with a healthcare professional first, as more research is needed to fully understand its long-term effects and benefits.
