How much oxalate is in black pepper?
Low · < 5 mg4 mg
per 1 tsp (2 g)
Eat freely. These foods barely move your daily total.
Very high per 100 g, tiny per serving — a perfect example of why serving size matters.
Most clinicians suggest calcium-oxalate stone formers stay under 100 mg of oxalate a day (stricter plans use 50 mg) — and eat normal calcium with meals, which binds oxalate in the gut. Values are estimates from published analyses; they vary by variety and preparation, so trust the band, not the decimal.
