Consult your physician prior to taking Runners Essentials

The DV (Daily Value) of elemental Iron as recommended by the FDA for adults ages 19-50 is 18 mg. Runners Essentials contains 22 mg, a slightly higher amount.

The UL (Upper Tolerable Intake Level) of elemental Iron as  defined by the FDA as the maximum daily intake UNLIKELY to cause effects for adults is 45 mg, which is MORE THAN TWICE what is contained in Runners Essentials.

Generally accepted treatment for Iron deficient individuals is in the range of 150-200 mg per day which is usually well tolerated. Adults with normal intestinal function have very little risk of iron overload from dietary sources of iron.

Intakes of greater than 20 mg/kg ( 1200 mg per day for a 140 lb person) can lead to gastric upset, constipation, nausea, abdominal pain, vomiting, and faintness. You would have to take over 100 capsules of Runners Essentials all at once to get 1200 mg of Iron (Please Don’t!)
