MultiThera® 1 Iron-Free

MultiThera® 1 Iron-Free

The amounts and ratios of nutrients used in this MultiThera® formula are based on a long history of clinical use and updated using the newest research findings.

The 1:1 calcium to magnesium ratio, high potencies of vitamins E, C, D3, and B-complex, bioactive forms of folate and vitamin B12, extra pantothenic acid for adrenal support,† and full complement of trace elements distinguish this formula from ordinary multiple vitamins.

This iron-free formula option is most suitable for the majority of individuals.  Copper is included because of its importance for SOD antioxidant enzyme activity and to maintain a healthy balance with zinc.
