According to the National Institutes of Health, taking certain vitamins and minerals together can reduce their effectiveness by inhibiting absorption. To maximize health benefits, it is crucial to understand which combinations to separate and address the question: **Are there any vitamins that shouldn't be taken together**?

In a study of over 26,000 patients with iron deficiency, those on long-term, continuous PPI therapy had a 3.6 times higher odds of having the condition [1.8.2]. This highlights the question: what does a PPI decrease absorption of, and what are the clinical implications?

According to the FDA, long-term use of proton pump inhibitors (PPIs) like omeprazole has been linked to low magnesium levels in the blood. This raises important questions about nutrient absorption, specifically, can I take magnesium and zinc with omeprazole safely and effectively, and how does this medication affect the body's mineral balance?

According to the National Institutes of Health, the weight-loss drug orlistat can decrease the absorption of vitamin A, potentially causing low blood levels in some individuals. It is crucial for patients and healthcare providers to know which medication can reduce absorption of vitamin A to prevent potential deficiencies and health complications.

According to a 2025 review of studies, elevated serum folate levels can worsen the neurocognitive effects associated with vitamin B12 deficiency. Understanding these complex interactions is crucial for anyone wondering what vitamins should not be taken together with folic acid, as improper combinations can hinder absorption and mask serious deficiencies.

While true biotin deficiency is rare, at least a third of pregnant women develop marginal deficiency despite normal intake [1.4.5]. Learning how to increase biotin absorption is key for metabolic health, and supporting healthy hair, skin, and nails [1.5.7, 1.2.2].

Studies show long-term use of acid-reducing drugs like H2 blockers is associated with an increased risk of vitamin B12 deficiency [1.3.2, 1.3.3]. So, can you take vitamin B12 with famotidine safely? Yes, but with important considerations for absorption and monitoring.

Over 300 biochemical reactions in the human body rely on magnesium, and supplementation is a popular way to ensure adequate intake. However, knowing what not to combine with magnesium glycinate is crucial, as certain drugs and supplements can interfere with absorption or create unwanted side effects.

According to the National Health Service (NHS), you should not take folic acid within 2 hours of taking indigestion remedies like antacids, as they can interfere with absorption. While it may seem convenient, understanding the reason for this separation is crucial for ensuring you get the full benefits of your folic acid supplement when you take folic acid and antacid together.

Data from the National Health and Nutrition Examination Survey shows that 57.6% of American adults have used a dietary supplement in the last 30 days [1.5.1]. But with so many people taking them, how do you know if multivitamins are working to improve your health?
