Modern medicine often relies on proton pump inhibitors and other acid blockers to relieve heartburn and stomach discomfort. Less well known, however, is that these medications can impair the absorption of vitamin B12. Hildegard of Bingen already recognized the central importance of healthy digestion for our well-being. She emphasized that weak stomach power can impair the utilization of important nutrients—a finding that is now being scientifically investigated.

Why stomach acid is indispensable for B12 absorption
Vitamin B12 in food is usually bound to proteins and is normally released by stomach acid. This process is the first step for the later absorption of the vitamin in the small intestine. Stomach acid can also activate important enzymes like pepsin, which play a role in further digestion.
Additionally, our body produces the so-called intrinsic factor, a protein from the stomach’s parietal cells. This binds to the released B12 and enables its absorption in the terminal ileum, the last section of the small intestine. With insufficient stomach acid, this complex mechanism can be impaired.
The effects of impaired B12 absorption often only become apparent after years, as the liver can store large amounts of the vitamin. B12 is important for various body functions and is needed for blood formation and nerve function. Especially older people often have lower B12 levels because stomach acid production naturally decreases.
Acid blockers in focus: effects and side effects
Proton pump inhibitors (PPIs) like omeprazole or pantoprazole are among the most commonly prescribed medications worldwide. They reduce acid production in the stomach’s parietal cells and are often taken over long periods. These medications fulfill their therapeutic purpose in various stomach diseases.
Scientific studies have shown that long-term use of acid blockers can be associated with altered B12 levels. Especially people over 50 who take these medications for more than two years can be affected. Reduced stomach acid can also affect the utilization of other nutrients such as iron, calcium, and folic acid.
Hildegard of Bingen already dealt intensively with weak digestive power and knew various traditional approaches to support stomach function. Her observations on the importance of balanced digestion are now being scientifically researched.
Natural support for stomach acid according to Hildegard
Saint Hildegard knew various herbs and methods traditionally valued for digestion. Particularly well-known are bitter herbs that have been used in folk medicine for centuries. Gentian root, wormwood, and centaury were among her preferred medicinal plants for digestive complaints.
These bitter herbs activate natural digestive processes through taste receptors. Even the taste on the tongue can trigger a reflex reaction of the stomach glands—a mechanism long known in traditional naturopathy. Hildegard recommended taking these herbs before meals to prepare digestion.
Besides the classic bitter herbs, Hildegard also relied on warming spices like ginger, galangal, and cinnamon. These have been traditionally valued for centuries to support digestion. They can stimulate the digestive fire and promote blood circulation in the stomach lining.

Preventive measures and holistic consideration
Those who need to take acid blockers permanently should have their B12 status checked regularly. Regular medical monitoring allows early detection of changes. In addition to medical supervision, natural approaches can support overall well-being without interfering with necessary medication.
A conscious diet with B12-rich foods such as meat, fish, and fermented products is generally recommended. In cases of significantly reduced stomach acid, special B12 supplements or forms like lozenges can be an option, as they bypass stomach acid.
The teachings of Hildegard von Bingen show us to view the body as a whole. A healthy lifestyle with balanced nutrition, regular exercise, and stress reduction can support overall well-being. Eating slowly, chewing thoroughly, and consciously enjoying meals are traditional approaches that have been valued for centuries to support natural digestion.
