EP 136: Which vitamins and minerals may be lacking when taking certain medications

In medical practice, prescribing a drug is always based on the risk-benefit balance principle: medications provide us with an essential benefit for treating pathologies or preventing complications, but they are not exempt from metabolic tolls. In this episode, we address drug-induced depletion in a clear and informative way, a silent phenomenon by which certain very common treatments can hinder the absorption, increase the elimination, or alter the activation of essential vitamins and minerals. Understanding this connection allows us to comprehend why symptoms such as fatigue, myalgia, insomnia, brain fog, or hair loss may appear after starting a treatment, remembering that knowing the cause is the first step to alleviating discomfort and improving quality of life without the need to abandon prescribed medication.

Throughout the talk, we meticulously analyze the most common pharmacological groups and the nutrients that are especially affected. We delve into proton pump inhibitors, such as omeprazole or pantoprazole, explaining that they are not mere "stomach protectors," but potent suppressors of the gastric acid necessary to digest proteins and correctly assimilate magnesium, vitamin D, calcium, iron, and, very critically, vitamin B12, whose progressive deficiency affects memory and constitutes one of the main reversible causes of dementia. Likewise, we explain the mechanism of statins for cholesterol, which block the hepatic synthesis of Coenzyme Q10, an antioxidant and mitochondrial nutrient essential for cellular respiration and muscle contraction, which justifies the frequent appearance of muscle pain or chronic fatigue. We also address metformin and its impact on vitamin B12 absorption, warning how this deficit can raise homocysteine (a pro-inflammatory molecule with an impact on cardiovascular health and fertility) if it is not adequately replenished.

In addition, we delve into the effects of oral contraceptives, which increase catabolism and reduce the hepatic activation of vitamin B6, favoring the appearance of seborrheic dermatitis or cracks at the corners of the mouth, and deplete reserves of magnesium, folate, and hepatic antioxidants. We also analyze the urinary loss of magnesium, thiamine (vitamin B1), and zinc caused by diuretics, the muscular and bone impact of corticosteroids, and the need to protect the gastric mucosa with vitamin C when taking acetylsalicylic acid (aspirin) continuously. Finally, we highlight the importance of always choosing the active and bioavailable chemical forms of each nutrient, such as methylcobalamin for B12 or pyridoxal-5-phosphate for B6, and we review some key food-drug interactions, such as the need to avoid grapefruit if taking statins or certain antihypertensives. In short, the episode invites us to abandon extremes to understand that drugs and targeted nutritional supplementation can coexist synergistically to protect our overall health.
