You should be fine, according to this: Health Risks from Excessive Iron
Adults with normal intestinal function have very little risk of iron overload from dietary sources of iron . However, acute intakes of more than 20 mg/kg iron from supplements or medicines can lead to gastric upset, constipation, nausea, abdominal pain, vomiting, and faintness, especially if food is not taken at the same time [2,5]. Taking supplements containing 25 mg elemental iron or more can also reduce zinc absorption and plasma zinc concentrations [3,78,79]. In severe cases (e.g., one-time ingestions of 60 mg/kg), overdoses of iron can lead to multisystem organ failure, coma, convulsions, and even death [18,80].
20 mg/kg (gastric upset, etc.) is 1,500 mg of iron if you weigh 75 kg; that’s a hell of a lot. 60 mg/kg (possibly fatal) is 4,500 mg if you weigh 75 kg.
Hopefully 35 mg or you will kill yourself. [35 g = 35,000 mg]
