FIRST Omeprazole is a brand-name prescription medication that contains the active ingredient omeprazole. Omeprazole is a proton pump inhibitor (PPI) that is used to treat conditions such as heartburn, gastroesophageal reflux disease (GERD), and ulcers by reducing the production of stomach acid. It is commonly prescribed to provide relief from symptoms of acid reflux and to help heal damage to the esophagus caused by stomach acid.

Prolonged use of FIRST Omeprazole can impact 7 essential nutrients.
Magnesium
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.

Vitamin C
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.

Vitamin B12
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.

Vitamin B 6 (as pyridoxal 5'-phosphate)
Vitamin B-6 helps regulate immune responses in the gut, potentially reducing inflammation that can contribute to digestive issues. One of the concerns of Gastro Esophageal Reflux Disorder ( GERD) or Gastric Reflux is the progression to more complicated condition such as Barrett’s Esophagus (BE) or even Esophageal adenocarcinoma (EAC) by increased inflammation. While treatment of GERD with Proton Pump Inhibitors or H2 Antagonists may help treat or reduce risk, a study on the effects of B Vitamins found that Vitamin B6 intake was significantly inversely related to the risks of all three lesions of GERD, BE or EAC. Patients concerned with these conditions should consider Vitamin B6 supplementation.

Vitamin K2 (Menaquinone-7)
Research demonstrates that vitamin D3 and K2 can provide greater benefit together. Vitamin D3 and K2 help move calcium into your bones, where it's most beneficial. This prevents calcium buildup in your arteries and blood vessels. Their combined action can boost bone health, promote cardiovascular health, and combat inflammation. Both vitamins show promise in regulating inflammation, a key factor in many health concerns. By collaborating, vitamin D3 and K2 offer a broader spectrum of benefits, potentially protecting against serious illnesses and promoting overall well-being.
