Make sure the formulation contains the effective dosage of the active ingredients. The effective dosage may vary by nutrient and individual. An individual’s specific nutritional needs may vary depending on your age, health status and other factors (such as pregnancy, breastfeeding, illness, physical activity level, etc.) When choosing a multivitamin, always refer to the RDA of the active ingredients.
What is RDA? RDA (Recommended Dietary Allowance) is defined as the intake that meets the nutrient needs of almost all (97 – 98%) individuals in that gender group, at the given life-stage. It is therefore the goal for dietary intake by the individual.
Read the label carefully. Product labels identify which nutrients are included and the quantities contained within each serving.
Get the basic water soluble and fat soluble vitamins and minerals. Most multivitamin preparations usually include the following: vitamin C, B1 (thiamin), B2 (riboflavin), B3 (niacin), B6 (pyridoxine), folic acid (B9), B12 (cyanocobalamin), B5 (panthothenic acid), biotin, A, E, D, zinc, calcium, magnesium and iron.
Look for extras. Some multivitamins are available in a variety of formulations that are aimed at helping people with specific nutritional needs or conditions. Some multivitamins can contain additional select active ingredients like antioxidants, herbal extracts, or formulations that are specialized to specific conditions, like vitamins for people with diabetes.
Formulations specifically for men and women. Choosing a multivitamin designed for your gender has a lot of benefits as men and women have different nutritional needs
