What is Booster C 600?

USANA’s new Booster C 600 product is designed to provide seasonal immune system support. It contains zinc, echinacea extract (Echinacea purpurea), black elderberry extract, and vitamin C, including USANA‘s proprietary Poly C® blend. Additionally, this product is provided as a lemon-berry flavored powder that can be taken directly or mixed with water, juice, or other beverages.

Most research on echinacea extract has looked at short-term use beginning at the onset of cold or flu symptoms. Research on efficacy and safety during long-term use is less established. Because of the potential for unwanted side-effects from overstimulation of the immune system, USANA’s Booster C 600 product should not be used continuously for more than two weeks at a time.

Can children use the Booster C 600 product?

USANA’s Booster C 600 product is not recommended for use in children under the age of 18. Echinacea purpurea has been extensively studied, but most of the research on efficacy and safety has been completed in adults. Risks and benefits for use in children is less established. If you have further questions regarding echinacea use in children, please consult with your child’s pediatrician.

When is the best time to take Booster C 600?

The most encouraging echinacea research has come from studies examining short-term use at the onset of cold or flu symptoms. Preventative use and use after symptoms have fully developed have shown mixed results.

As with any dietary supplement, taking Booster C 600 with a meal or snack can reduce the potential for stomach upset.

Finally, the recommended dosage of one stickpack per day should not be exceeded.
