Our board of nationally- and internationally-recognized doctors have a hand in the development of all NSI formulas, and because of that, everything we put our name on contains the purest, most potent ingredients for your maximum health.

Multi-vitamins and nutrients vary in their standards and potency. Your typical A-Z multi-vitamin, for example, contains many of the same nutrients as your specialized premium vitamin, but at a lower grade or blend. Lower grade vitamins, nutrients and herbal supplements are sold in non-standardized forms-resulting in ineffectiveness.

Standardized nutrients are the only things we put in our NSI vitamins and nutritional supplements. Standardization isolates the portion of a plant or herb that contains the active ingredient that produces the actual clinical benefit. For example, 100 mg of a whole plant herbal nutrient in raw (non-standardized) form may contain only 5 mg of the active ingredient. The active ingredient is then isolated and concentrated through this special process known as standardization.
