Product Description


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.

What is MultiThera 1 Iron-Free?

MultiThera 1 Iron-Free is a high-potency multiple vitamin/mineral supplement to support optimal health in adult men and women. It contains a full spectrum of bioavailable vitamins, minerals, trace elements, antioxidants, and natural carotenoids. MultiThera 1 Iron-Free is part of the MultiThera line of multi-nutrient products. It is iron-free and provided in tablet form.

How is MultiThera 1 Iron-Free different from regular multiple vitamin/mineral products?

MultiThera 1 Iron-Free provides all of the vitamins found in regular multivitamin products and includes added amounts of vitamins C, E, and B-complex vitamins, plus calcium, magnesium, and other crucial minerals and trace elements. In addition, this product contains RRR-alpha tocopherol (natural-form vitamin E) and beta-carotene (vitamin A) to support optimal absorption and utilization by the body.

Why take vitamins/minerals at levels higher than the Recommended Daily Allowance (RDA)?

RDA levels of nutrients are determined based on their ability to prevent deficiency. Research suggests that taking certain essential nutrients above these levels may not only prevent deficiency but support health in other ways. MultiThera 1 Iron-Free provides many of its ingredients in bioavailable forms and at levels above the RDA to support optimal health.

MultiThera 1 Iron-Free provides a full spectrum of vitamins, minerals, trace elements, antioxidants and natural carotenoids. Compared to many other multivitamin and mineral products, these ingredients are provided in bioavailable forms and at levels at or above the RDA to support optimal health.

Why are 6 tablets per day needed?

MultiThera 1 Iron-Free provides a full spectrum of vitamins, minerals, trace elements, antioxidants and carotenoids. Many of these ingredients are provided at or above the RDA to support optimal health. In addition, bioavailable forms of certain vitamins and minerals typically have larger molecular structures, which requires higher total milligram amounts to provide equivalent elemental nutrition.

What steps are taken to ensure that nutrients in MultiThera 1 Iron-Free are absorbed?

MultiThera 1 Iron-Free provides bioavailable ingredients to support optimal absorption and action in the body.

Vitamin B12, calcium and other minerals like magnesium are provided in forms that are easy to absorb relative to forms commonly found in other multi-nutrient products. Folate is provided in a patented active form called Metafolin that can be absorbed and utilized directly by the body. In addition, every lot of MultiThera 1 Iron-Free is tested according to official USP protocols ensure tablets break down in 45 minutes or less after ingestion.

Why are active forms of folate and B12 important?

Folate and vitamin B12 help maintain the normal methylation and metabolism of substances like homocysteine. Biologically active forms of folate (Metafolin L-5-methyltetrahydrofolate) and vitamin B12 (methylcobalamin) are used in MultiThera 1 Iron-Free.
