Chloride is a vital electrolyte found in the body. Chloride balance is maintained by the kidneys, and it is a primary factor in pH balance. (source, source)
Low serum chloride levels may stem from physiological factors affecting kidney function, as the kidneys play a crucial role in chloride balance within the body. From a nutritional perspective, inadequate intake of chloride-rich foods or excessive loss of water through sweating can also contribute to decreased chloride levels. (source, source)
Prioritize chloride-rich foods: Consumption of chloride-rich foods has been shown to increase chloride levels. (source, source) Recommendation: Consume at least two servings of chloride-rich foodsolives a week.
One serving examples: Table Salt (1 tsp), Seaweed (dried) (3 g), Green Olives (10 large olives), Cheddar Cheese (1.5 oz)
Maintain fluid balance: Overconsumption of water can reduce serum chloride. (source) Excess water dilutes the concentration of electrolytes in the bloodstream, including chloride. The kidneys then work to eliminate excess fluid, resulting in increased excretion of chloride in urine. (source, source) Ensuring proper hydration will help regulate chloride levels. Recommendation: Monitor water consumption to ensure no more than 0.5 fl oz of water per pound of body weight per day.
Supplement with electrolytes: Lysine chloride supplementation has been associated with increased serum chloride levels. (source) Chloride compounds supply chloride ions when ingested, which are then absorbed into the bloodstream, creating readily available chloride that can be used to maintain electrolyte balance. (source) Recommendation: Supplement with a variety of electrolytes with at least 500 mg of sodium.
Elevated serum chloride levels can often be attributed to physiological factors such as dehydration or kidney function, as the kidneys play a vital role in maintaining electrolyte balance. From a nutritional standpoint, excessive intake of salt or chloride-rich foods can contribute to higher chloride levels. (source, source)
Limit chloride-rich foods: Consumption of chloride-rich foods has been shown to increase chloride levels in the body. (source, source) Limiting the intake of chloride-rich foods will decrease chloride concentrations. Recommendation: Monitor and limit excess consumption of chloride-rich foods, like seaweed, tomatoes, and olives.
Prioritize proper hydration: Loss of electrolyte-free water is associated with high levels of chloride. (source) Maintaining fluid balance will aid in regulating chloride concentrations. Recommendation: Drink at least 0.5 fl oz of water per pound body weight per day.
Avoid chloride supplements: Consumption of chloride has been shown to increase chloride levels. (source, source) Limiting the intake of chloride will decrease chloride concentrations. Recommendation: Monitor chloride intake and concentrations in supplements.
