USANA Supports Clinical Studies

USANA Essentials vs. Four Select Competitor Products

A simple way to examine the quality of a nutritional supplement is to examine its bioavailability. Bioavailability is defined as the degree and rate at which a substance is absorbed by the body. What good does it do to take a supplement if it is not effective due to either low amounts of nutrients or poor bioavailability?

USANA conducted an in-house clinical study to assess the bioavailability of five diverse dietary supplements, including the USANA Essentials vitamin, mineral, and antioxidant supplement, in comparison to four other brands on the market:

1) a plant-sourced vitamin/mineral supplement;
2) a food-based supplement;
3) a leading one-a-day vitamin/mineral supplement;
4) a gel-based vitamin/mineral supplement

THE RESULTS: For every nutrient examined, the USANA Essentials had the best bioavailability profiles. The USANA Essentials outperformed the other products tested by providing the highest levels of key nutrients most effectively. Therefore, it appears that the USANA Essentials provides optimal levels of bioavailable nutrients to obtain blood levels significantly higher than can be achieved from for other competitors' products. Thus, if taken twice daily, one could expect to maintain elevated levels of these nutrients throughout the day to help obtain optimal nutritional status.
