A typical Western menu delivers 3 600\u20134 000 mg of sodium but only ~2 500 mg potassium and ~250 mg magnesium\u2014flipping the ideal Na:K ratio on its head. Processed foods add hidden salt, whereas produce, legumes, and nuts supply potassium and magnesium.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why Electrolytes Matter Even More for Endurance Athletes<\/h2>\n\n\n\n<p><strong>Sweat sodium losses scale with duration.<\/strong> Average sweat contains ~48 mmol Na\u207a \u2248 1 100 mg L\u207b\u00b9.

While most people can cover baseline needs through a balanced diet rich in fruits, vegetables, dairy or fortified plant alternatives, and mineral-dense whole grains, sweat losses during prolonged or high-intensity exercise can far outstrip what food alone replaces. For runners, cyclists, triathletes, and other endurance athletes, replenishing roughly <strong>300 \u2013 600 mg of sodium per hour<\/strong>\u2014alongside potassium, calcium, and magnesium\u2014has been shown to reduce the risk of muscle cramps, dizziness, and exercise-associated hyponatremia, helping you sustain power output and recover faster. Practical tactics include pre-loading electrolytes before long sessions, sipping a tailored drink during activity, and tracking body-weight changes to gauge fluid loss.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p><strong>Disclaimer:<\/strong> The information provided here is intended for general educational purposes only and does <strong>not<\/strong> constitute medical, nutritional, or training advice.
