🧪 Formulation Notes

Contains: Soy

The iron in SierraSil is naturally-occurring and shown to be safe for human consumption. Research shows that only 1.1 mg of iron per serving or 6% of Daily Value is the maximum amount that is potentially bioaccessible out of the 40 mg total it contains. SierraSil cannot be used as a dietary source of iron. The suggested intake and clinical strength levels of SierraSil will not supply enough iron to satisfy RDI needs.
