One of the most common types of over-the-counter medications my patients take are medications for reducing acid reflux. Unfortunately, over time, this can lead to some health challenges which include, difficulty digesting food, malabsorption, and nutritional deficiencies. This is because without adequate stomach acid it becomes impossible to digest our food properly.
Our stomach usually produces stomach acid via Parietal cells. Medications that block the release of stomach acid from Parietal cells also block something else called “intrinsic factor.” Intrinsic factor is a carrier protein that the parietal cells release into the stomach when we eat foods that contain B12 (such as animal products). However, when people take acid-blockers they can also block the parietal cells from releasing intrinsic factor; making it impossible to absorb vitamin B!2. Consequently, long-term use of acid blockers can result in B12 deficiency and I advice my patients who are unable to get off acid blockers to supplement with B12.
If your doctor has placed you on an acid blocker, speak to him/her about B12. B12 is a very important vitamin that is vital for several processes in the body. B12 gives us energy, helps in DNA synthesis, and protects our nerve cells. B12 is also helpful in red blood cell division. People with low levels of B12 often experience a medical condition called “neuropathy”, or pain in the nerves (often in the feet and hands). they may also experience a form of anemia where red blood cells continue to grow but do not divide called “megaloblastic anemia.”
If you are concerned about getting enough B12, and you are taking an acid-blocker, I recommend taking a sublingual B12. This is a B12 that you can take under the tongue bypassing the stomach so that it can be absorbed more easily. B12 sublingual is sold in 500mcg, 1mg and 5mg dosages. I also advice taking the form methylcobalamine as it is of higher quality than the cheaper quality cyanocobalamine.
