Electrolytes

Electrolytes can speed up rehydration by helping water be retained. For this purpose, DripDrop Hydration Powder is effective. It's a hypotonic solution that leverages accelerated sugar-based osmotic transport. Gatorade and other drinks are isotonic or hypertonic: they add electrolytes but don't improve hydration.

Travel and exercise can cause sweating. Planes have low humidity comparable to the Gobi desert, causing loss of moisture. The most effective electrolyte supplement for restoring electrolytes lost in sweat are SaltStick FastChews.

Electrolytes effect general metabolism and health, which effect cognitive speed and overall energy levels. The most effective off-the-shelf solution is the BodyArmor sports drink. The key nutrients are potassium, magnesium, and zinc. Potassium can be obtained by eating foods such as bananas and potatoes. Magnesium can be obtained by taking magnesium supplements such as magnesium glycinate, magnesium malate, and magnesium l-threonate. Magnesium oxide and citrate are ineffective.

For sleep, magnesium supplements are most effective. Taking a somewhat large dose (200-500% DV) is safe.
