The lethal dose of table salt (sodium chloride, NaCl) is usually estimated to be around 0.4 to 1.1 grams per kilogram (g/kg) of body weight when ingested all at once. Doses above 2.2 g/kg (1 g/lb) can be fatal.
Around 9+ tablespoons of salt consumed rapidly could be fatal for an average adult.

Salt Toxicity (Hypernatremia) Symptoms:
Around 9+ tablespoons of salt consumed rapidly could be fatal for an average adult.
Lethal Dose of Table Salt (NaCl):
- Estimated lethal range: 0.4–1.1 g/kg body weight (0.2–0.5 g/lb)
- Typically fatal: 2.2 g/kg (~1 g/lb) if consumed rapidly
- Fatal dose by body weight:
- 50 kg (110 lbs): 110 g salt (7 tbsp)
- 60 kg (132 lbs): 130 g salt (8 tbsp)
- 70 kg (154 lbs): 150 g salt (9 tbsp)
Salt Toxicity (Hypernatremia) Symptoms:
- Initial: extreme thirst, nausea, vomiting, diarrhea, headache
- Progressive: confusion, agitation, muscle spasms, seizures, high blood pressure, difficulty breathing
- Severe/fatal: brain cell shrinkage → coma, neurological damage, death from brain swelling or organ failure
