Semaglutide Impact on B12 Absorption: Understanding the Connection

Ozempic®, the brand name for semaglutide, has gained popularity for managing type 2 diabetes and supporting weight loss. Its potential influence on vitamin B12 absorption has become a topic of concern among healthcare professionals and patients.

Semaglutide works by mimicking GLP-1, a hormone that helps control blood sugar levels. It causes the pancreas to release insulin, decreases glucagon production, and slows down stomach emptying. While these effects contribute to its therapeutic benefits, they may also impact nutrient absorption, particularly vitamin B12.

The slowing of gastric emptying and potential reduction in stomach acid production can affect B12 absorption. Vitamin B12 requires stomach acid and intrinsic factor, a protein produced by the stomach, for proper absorption. This alteration in the gastrointestinal environment may lead to lower B12 levels over time, potentially resulting in a deficiency if not addressed ^[1].

Studies have explored semaglutide's impact on vitamin B12 levels, with some suggesting it may alter nutrient absorption. For instance, research has found that some patients experienced lower vitamin B12 levels after starting semaglutide treatment. These instances were generally rare and mild, indicating the need for more comprehensive research to fully understand this relationship.

It's important to note that while taking Ozempic® doesn't automatically necessitate B12 supplementation, it's crucial to be aware of potential B12 deficiency symptoms. These may include fatigue, weakness, pale skin, shortness of breath, numbness or tingling in extremities, balance problems, cognitive issues, and mood changes.
