Less than the amount shown is not safe: any chocolate is a reason to call. Heart effects are listed from 40 mg/kg, which is twice these grams, and seizures from 60 mg/kg, three times.
Milk chocolate has 2.3 mg of methylxanthines per gram, dark or semisweet 5.6 (the top of Merck’s range) and unsweetened baking chocolate 15.5.
