PPIs and nutrient depletion: new research confirms a long-standing concern

A new study published in ACS Omega adds important animal model evidence: researchers administered omeprazole to rats for 10, 30, and 60 days and measured effects on mineral status across blood and multiple organs.

Hemoglobin and red blood cell counts declined progressively over the treatment period, while iron accumulated in the liver and spleen even as blood iron levels fell, a pattern consistent with impaired absorption and compensatory redistribution.

Hepatic copper concentrations dropped significantly after 30 days, which matters because copper plays a critical role in the pathway through which iron becomes available for hemoglobin synthesis. Calcium redistribution patterns suggested potential bone resorption, consistent with what longer-term human studies have observed.

PPIs were only ever approved for short-term use, typically no more than 2 weeks, yet many people take them for years or even decades, often without fully appreciating what that means for their nutritional status. If you're relying on a PPI long-term, speak with your healthcare practitioner about alternatives and a thorough nutritional assessment.
