TRIORAL Rehydration Electrolyte Powder – Oral Rehydration Salts for Dehydration – Supports Hydration during Workouts, Fluid Loss, and Daily Wellness – 100 Drink Mix Packets

Trioral has about 1600mg of sodium plus potassium. You need both plus magnesium. So I take magnesium with L theanine at night. Trioral comes in a 100 pack for $40 on amazon It matters which kind of magnesium you take because some can make people constipated and stuff so find what works for you and consult your doctor.
