Experts warn indiscriminate supplement stacking can jeopardize health

In a recent interview, clinical pharmacist Jim LaValle emphasized that supplement regimens must be personalized rather than a blanket "one of everything" approach. He recommends using blood tests to pinpoint deficiencies, such as low magnesium or iron, before introducing specific products. While nutrients like zinc support immunity, excessive doses may trigger digestive issues or copper deficiency, and vitamins A and D can become toxic at high levels.

LaValle warns that the surge of online wellness advice often pushes consumers to stack multiple supplements and peptides, increasing the risk of adverse interactions. He advises that any supplementation be coordinated with healthcare professionals, especially for those on prescription drugs or with underlying health conditions. Proper interpretation of lab results can help set realistic health or performance goals without unnecessary overuse.
