Vitamin A and beta carotene are essential for maintaining the integrity of the cornea and the light-sensing pigments in the retina, so deficiency greatly increases the risk of night blindness and other ocular pathologies. In vitamin A deficient regions, hundreds of thousands of children each year develop xerophthalmia, ranging from conjunctival and corneal dryness to corneal ulceration and keratomalacia, which can progress to irreversible blindness if not corrected. Even subclinical deficiency can impair dark adaptation and increase susceptibility to eye infections, making adequate vitamin A and carotenoid intake a critical foundation for long-term visual health. This medication is commonly used for Stomach Acid.

Some side effects may be linked to nutrient depletion caused by this medication.
Long-term use of H2 blockers may increase your risk of zinc deficiency. These medications work by reducing stomach acid, which is crucial for absorbing zinc from food. Zinc is an essential mineral that supports a healthy immune system and wound healing. Deficiency can lead to various health problems. A study directly investigated the impact of cimetidine, a common H2 blocker, on zinc absorption. The research found that zinc absorption significantly decreased after cimetidine administration, highlighting the role of stomach acid in this process. Individuals who take H2 blockers for extended periods should consider supplementation with zinc to protect against a deficiency.
Regular use of non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen may decrease your folic acid (folate) levels. This is because NSAIDs can interfere with how your body processes folate. If you take OTC pain relievers regularly, consider folate supplementation to avoid potential deficiencies.
Research suggests that long-term use of medications that reduce stomach acid, like H2 blockers and PPIs, may be linked to vitamin B12 deficiency. Stomach acid plays a role in releasing vitamin B12 from food, and reduced acid levels caused by these medications could hinder proper B12 absorption. Some studies find an increased risk of B12 deficiency, particularly in older adults or those using these medications for extended periods. Individuals taking H2 blockers or PPIs long-term should consider vitamin B12 supplementation.
Recent suggests that damage caused by free radicals in tissues plays a role in stomach ulcers (gastric mucosal lesions) caused by nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen. Based on this, it was investigated whether the amino acid taurine could protect the stomach lining from ibuprofen-induced damage. The study also examined the effects of taurine on the stomach's natural antioxidant defenses, including enzymes like superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPX), as well as a molecule called glutathione (GSH). It found that giving taurine orally for three days in a row protected the rats' stomach linings from the ulcers caused by ibuprofen. Additionally, taurine significantly reduced a marker of free radical damage (lipid peroxidation) in the ibuprofen-treated rats.
Vitamin A plays a vital role in maintaining a healthy gut lining, which is crucial for overall stomach health. This is why some research has explored its potential use alongside other medications for treating ulcers. Research suggests vitamin A supplementation may be effective specifically for treating ulcers alongside H2 blockers.
