Yes, it is possible for taking B12 on an empty stomach to cause nausea. Vitamin B12 is an essential nutrient that our body requires for the proper functioning of the nervous system, proper brain function, and the production of red blood cells. However, taking vitamin B12 on an empty stomach can cause unpleasant side effects. When you take vitamin B12 on an empty stomach, it enters your system too quickly, and can cause an upset stomach, nausea, or vomiting.
The reason for the nausea is believed to be due to the release of gastric acid. When B12 enters your stomach, it triggers the production of gastric acid, which is required for proper digestion. However, when vitamin B12 is taken on an empty stomach, there is nothing else in the stomach to break down the acid that is released, causing nausea.
Therefore, it is generally recommended that you take B12 with food to avoid nausea. Taking B12 with food can help slow down the absorption of the vitamin and reduce the impact of gastric acid on the stomach lining. If you continue to experience nausea after taking B12 supplements, it may be wise to consult with your physician to rule out any underlying medical conditions that could be causing the issue.
Taking B12 on an empty stomach has the potential to cause nausea. It is important to take this essential vitamin with food to avoid this unpleasant side effect and ensure maximum absorption in the body.
