Magnesium depletion destabilizes neuromuscular transmission and ATP-dependent muscle relaxation, which can cause muscle cramps, tremors, weakness and restless legs. This medication is commonly used for Stomach Acid.
Clinical reports and modern reviews note that hypomagnesemia is associated with muscle cramps and spasms; mechanistic work links low magnesium to impaired ATP handling and sustained muscle contraction.

Some side effects may be linked to nutrient depletion caused by this medication.
Studies find that proton pump inhibitors (PPIs) may increase your risk of magnesium deficiency. A large study involving over 100,000 participants found a significant association between PPI use and lower magnesium levels (hypomagnesemia). PPIs work by reducing stomach acid production, which can also play a role in magnesium absorption. Individuals taking PPIs, particularly long-term use, should consider magnesium supplementation to help protect against deficiency.
Long-term use of PPIs might raise the risk of calcium deficiency and weaken bones. A potential mechanism for this is chronic hypergastrinemia, a condition where the stomach produces excess gastrin due to PPI use. This can lead to parathyroid hyperplasia, where the parathyroid glands overproduce a hormone that pulls calcium from bones. Additionally, PPIs significantly reduce stomach acid production, which can hinder calcium absorption from food in the intestines. Individuals taking PPIs, especially individuals at higher risk of bone issues or those on long-term PPI therapy, should consider calcium supplementation to help protect against deficiency.
There is evidence that proton pump inhibitors (PPIs) might decrease vitamin C levels in the body. A study showed that even a short course of omeprazole, a common PPI, reduced vitamin C levels in healthy volunteers, regardless of their dietary intake. This suggests that PPIs may reduce the bioavailability of vitamin C, meaning the body has a harder time absorbing and using it. Vitamin C plays a crucial role in immune function and antioxidant defenses and therefore individuals using PPI therapy should consider supplementation with vitamin C to protect against a deficiency.
