Why are there color variations in the tablets?
The raw ingredients used in USANA products come from a variety of sources. Many are derived from natural sources. These natural sources (usually plants) can vary in color from one season to the next and from batch to batch. Because of the natural variations in plants, the tablet color may also vary slightly from one batch to the next.
However, this should not be viewed as a quality concern. USANA always tests for the chemical markers (active constituents) of these compounds to ensure they are both pure and potent.
Many companies color their tablets to mask naturally occuring color variations. USANA does not add any colorants to its tableted products.
