Multithera® 1 Iron-Free

A widely preferred multiple formula, 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. Supplemental iron is unnecessary for most adult men and women and may be potentially harmful, as excessive amounts have been associated with heart disease, arthritis, and cellular damage. Copper is included because of its importance for SOD antioxidant enzyme activity and to maintain a healthy balance with zinc. This concentrated formula is designed to fit into 6 tablets daily. A clear, water-soluble cellulose coating protects the stability of the nutritional ingredients and makes the tablets easy to swallow. Each batch is tested using USP protocols to ensure proper tablet disintegration to help maximize nutrient bioavailability. MultiThera® 1 is especially recommended for men, postmenopausal women, and women with light or normal menstrual flow who may not need supplemental iron.
