Chloride

Chloride is a key electrolyte that works alongside sodium and CO₂ to regulate fluid balance, acid-base status, and electrical activity in cells. It doesn’t get much attention, but shifts in chloride can quietly reflect dehydration, adrenal stress, metabolic acidosis, or electrolyte imbalances. It’s a key buffer for real-time pH and hydration dynamics, especially when training hard or sweating heavily.
