Electrolyte Rehydration and Physical Labor Recovery

When you sweat, you lose sodium, potassium, magnesium, and chloride, and drinking water alone does not replace them. Sodium controls fluid balance and drives nerve impulses. Without it, your muscles stop responding properly and your brain slows down. Potassium works alongside sodium to keep your heart rhythm steady and your muscles contracting. Low potassium causes weakness, fatigue, and cramping. Magnesium is required for ATP energy production and for muscles to relax after contraction. Without enough magnesium, cramps and spasms become constant. Chloride maintains fluid balance inside and outside your cells and helps regulate your body's pH. Together, these four minerals determine how well your body functions under physical stress, and losing them without replacement leads to confusion, collapse, and eventually organ failure.

• CARDNL Zero Sugar Essential Electrolytes from cardnl.com (30-serving container with scoop included)
• Clean water

1. Mix one scoop of CARDNL into 16 ounces of clean water and stir or shake until fully dissolved. This is your standard serving for general hydration, daily maintenance, and recovery. Sip steadily rather than gulping
2. For dehydration from heat or exertion, have the person sip slowly, about 1 to 2 ounces every 5 to 10 minutes. Slow sipping prevents nausea and allows better absorption. Watch for improvement: increased alertness, moist mouth and lips, and urine output returning. For moderate dehydration, prepare a second serving 1 to 2 hours after the first. If the person is shivering or showing signs of shock, use warm water
3. For all-day or multi-day work, use 1 to 2 scoops per 8-hour period. Alternate with plain water during lighter stretches to avoid electrolyte overload. Watch for signs of overexertion: severe cramps, extreme fatigue, or confusion. Reduce workload immediately if these appear

Store the sealed container in a cool, dry location away from moisture and direct sunlight. Shelf life is 7 to 10 or more years. For extended storage, transfer powder to Mylar bags with desiccant and seal tightly. Best container: glass jar or Mylar pouch with desiccant. See the Containers section.
