In a growing trend of self-prescribed wellness, many Indians are bypassing doctors and turning directly to dietary supplements, often lured by marketing that promises miraculous health benefits. However, this rush to join the latest supplement craze can have serious, unintended consequences for your health. Highlighting this very risk, Dr. Miranda Layton, an NHS doctor and marathon runner, has issued a stark warning about a particularly popular supplement: electrolytes.
The Electrolyte Craze: From Gyms to Everyday Life
The world of fitness supplements sees trends come and go, from protein shakes to creatine. The current viral sensation is electrolyte supplements. These products contain essential minerals like sodium, potassium, and magnesium, which the body loses through sweat during strenuous activities like intense gym sessions, long-distance running, or hot yoga.
For athletes and those engaged in prolonged, high-intensity exercise, replenishing these minerals is crucial to prevent side effects like muscle cramps, weakness, nausea, and headaches. The concerning shift, as noted by Dr. Layton, is that more and more people are now consuming these supplements daily, regardless of their actual activity level or need.
The Doctor's Dire Warning: Salt, Pressure, and Heart Rhythm
Dr. Miranda Layton took to Instagram to share a critical message often overlooked in fitness marketing. "Here is what the fitness industry doesn’t want you to know: You might be drinking too many electrolytes," she wrote. She explained that most electrolyte drinks are high in sodium, which is essentially salt.
"If you cook your food with salt and don't mind adding more on top, then you are already consuming more than enough," she stated. The long-term consequence of excessive sodium is elevated blood pressure. More alarmingly, in the short term, overconsumption of electrolytes can cause dangerous changes to heart rhythm, "especially if you are not dehydrated."
Dr. Layton clarified that daily electrolyte supplementation is only necessary for a specific set of circumstances: if you run long marathons, practice hot yoga, are recovering from a severe hangover, or have a diet completely devoid of added salt. For the average person, they are often unnecessary and potentially harmful.
Expert Backing: When Are Electrolytes Actually Needed?
Dr. Sara Rosenkranz, an associate professor at the University of Nevada, Las Vegas, provided scientific context in a conversation with the American Heart Association. Electrolytes are minerals with an electric charge vital for signaling muscles and nerves, regulating blood pressure, heart rate, and hydration.
However, Dr. Rosenkranz emphasized that most people consume adequate amounts of these minerals through their regular food and beverages. The problem of excess sodium is widespread; while federal dietary guidelines recommend no more than 2,300 milligrams per day (about one teaspoon), average intake often exceeds 3,400 mg.
Her advice mirrors Dr. Layton's warning: If your exercise lasts less than 75 minutes and is not of very high intensity, "then there's absolutely no need for electrolyte supplementation in those cases. And you can really just hydrate with plain water."
The key takeaway is to critically analyse whether your body truly requires a new supplement trend before jumping on the bandwagon. The second and most crucial step is always to consult a qualified healthcare professional before making any changes to your diet or supplement regimen.
