Dosage information is for harm reduction purposes only. Individual sensitivity varies greatly. Always start with the lowest effective dose and work your way up slowly. Never eyeball doses — use a milligram scale.
## Overdose Profile Acute toxicity from black seed oil is extremely unlikely at any reasonable dose. Animal toxicity studies have established LD50 values for thymoquinone at approximately 794-870 mg/kg in mice (oral), which extrapolates to doses far exceeding any plausible human intake from supplementation. ## Excessive Intake Consuming large amounts of black seed oil (well beyond recommended doses) may cause: - Significant gastrointestinal distress: nausea, vomiting, diarrhea, abdominal cramping - Hypotension (excessively low blood pressure) in individuals taking antihypertensives concurrently - Hypoglycemia in individuals on antidiabetic medications - Increased bleeding tendency due to antiplatelet effects ## When to Seek Medical Attention Seek medical evaluation if you experience: - Signs of allergic reaction (rash, swelling, difficulty breathing) — rare but possible - Symptoms of hypoglycemia (shakiness, confusion, sweating) if combining with diabetes medication - Unusual bleeding or bruising if combining with blood thinners - Severe gastrointestinal symptoms that do not resolve
