An All-Star Duo for Immune Support: Quercetin and Vitamin C*

When you think about immune support and supplements, vitamin C probably comes to mind right off the bat.* But how about quercetin? Probably not one of the first ingredients you think about.

Where Can I Find Quercetin?
Even if quercetin sounds a bit unfamiliar to you, you’ve probably consumed it often in many foods and beverages without realizing it. In fact, this fat-soluble flavonoid is found in onions, apples, tea, berries, and grapes. Supplements, however, tend to use sources that provide heavier concentrations of quercetin, such as the flower buds from the Japanese pagoda tree (Sophora japonica).


Why is Quercetin Important?

The reason quercetin is a big deal for immune health is that, like an all-star fielder, it can cover a lot of bases. That includes sinus, lung, and respiratory function, plus a healthy histamine response, making this nutrient a must-have in any season.*†

But while quercetin is highly regarded and frequently recommended, it can be tough for the body to effectively absorb this important fat-soluble flavonoid. In other words, keep eating those healthy foods that contain quercetin, but when you want a supplement, look for a more enhanced experience, like Quercetin with Vitamin C.

A Duo that Delivers
Quercetin with Vitamin C delivers two of the most effective immune-supporting nutrients in the world.* The quercetin in this formula is paired with a proven delivery system GammaSorb®, which consists of gamma cyclodetrin. GammaSorb had been shown to increase the absorption of certain hard-to-absorb (fat-soluble) dietary ingredients. A plant-based oligosaccharide, the gamma cyclodextrin surrounds hard-to-absorb and fat-soluble ingredients in an open-ended microscopic structure, the exterior of which is water-soluble, helping to escort the nutrients through the lining of the intestines and into the bloodstream.*

In this formula, this enhanced bioavailable quercetin is paired with vitamin C, which works together with quercetin–but along different routes of absorption–for more comprehensive immune support.*

While you’re most likely getting vitamin C from foods, getting a consistent amount—as found in this formula—is best for reliable daily support. Vitamin C can also aid in quercetin absorption, making it even more effective.*

When immune support is top of mind, it’s a great idea to get some all-star players on your team. The synergistic combination of Quercetin with Vitamin C can help you maintain a healthy, strong immune system every day, all year long.*
