The NutriSearch Comparative Guide to Nutritional Supplements™† independently reviews and compares 1,500 nutritional products and features product ratings.
A 5-Star Gold Medal rating is the highest rating a product can receive.
Each product included in the guide is given a starred rating based upon a model developed by NutriSeach known as the Blended Standard. It is based on a compilation of recommended daily nutrients from 12 independent nutritional authorities. In order for a nutrient to qualify for the Blended Standard, three of the 12 authorities must cite a recommended daily intake for the nutrient. Within the Blended Standard, there are 47 nutrient categories, consisting of 19 vitamins or vitamin-like factors, 15 minerals, a number of antioxidant and bioflavonoid complexes, and more.
The recommendations for daily intake in the Blended Standard are the appropriate levels healthy adults should take for 18 different health support criteria, including, but not limited to, completeness, potency, and mineral forms.
Products awarded 5 stars represent products possessing health support characteristics that are clearly superior to the majority of the products on the market.
All 5-star rated products are invited to submit proof of manufacturing quality and product content in the form of certification from independent certifying authorities. Those who provide such standards qualify for the NutriSearch Medals of Achievement Program.
