Reports are voluntary and unverified — they record what someone experienced while taking something, not what the compound caused. Counts skew towards products people take a lot of, and a serious outcome is more likely to be reported than a mild one, so these are not rates. How we filter them →

Too little
- Chloride deficiency (hypochloremia) symptoms:
- Dehydration and electrolyte imbalance
- Muscle cramps and weakness
- Poor digestion and reduced stomach acid
- Fatigue and general weakness
- Acid-base imbalance (metabolic alkalosis)
- Usually occurs with severe fluid losses
Too much
- Chloride excess symptoms:
- High blood pressure (with sodium)
- Fluid retention and edema
- Kidney strain and dysfunction
- Electrolyte imbalances
- Usually related to high salt (sodium chloride) intake
