And, if you're "in the know," then Zinc might also be on your immune support radar.

But do you know about Quercetin?

Odds are, if you've been following the health news over the past couple of years, then you've heard this hard to spell nutrient mentioned alongside Vitamin C and Zinc a few times.

You may even know that Quercetin is a flavonoid found in small amounts in foods such as apple peels, asparagus, and onions.

Unfortunately, even as generic Quercetin supplements have started flying off the shelves, one startling fact has come to light: ordinary Quercetin is hard to absorb.

At Purity Products^®, we don't believe in "ordinary" — so we made it our mission to find a Quercetin that can deliver vital immune system support via superior absorption.

In fact, clinical studies have shown that the PhytoActivated Quercetin in Ultimate Quercetin^™ packs 20X the absorption power of "off the shelf" Quercetin formulas.¹

But of course, we didn't stop there — we pumped up the immune system support by teaming this 20X absorption power with Vitamin C, Zinc, and other co-factors to give you a more robust approach to immune system support (plus, some amazing side benefits).*

But it is in combination with Zinc that Quercetin really shines. Quercetin is a Zinc ionophore — which means that it helps Zinc penetrate your cells.³ And Zinc is known to play an important role in immune system function.*

The further addition of Vitamin C, along with Citrus Bioflavonoids and other co-factors, takes your immune system to the next level while providing additional antioxidant defense.*

2. Respiratory Health & Lung Function
Your lungs play a vital role in both immune system function and blood oxygenation. Quercetin has been studied for decades and touted as a superstar when it comes to promoting respiratory and lung health — and the past 2 years have seen an acceleration in that research.*

Think of Ultimate Quercetin^™ as your partner in taking a deep breath, especially when you are outdoors during the spring.

4. Exercise Performance
You may not immediately put together the connection between immune health and exercise performance, but research into Ultimate Quercetin's^™ PhytoActivated Quercetin Phytosome^® has revealed that it can support optimal physical performance and prompt recovery after exertion.*

One amazing study even saw triathletes become 11% faster when using the active ingredient in Ultimate Quercetin^™!⁵

5. Skin Health
Antioxidants are important to skin health, especially when it comes to protecting your skin from the aging effects of oxidative stress. Ultimate Quercetin^™ delivers antioxidant protection from our PhytoActivated Quercetin, Vitamin C, and other co-factors.*

Plus, Vitamin C promotes healthy collagen formation and strong connective tissue.*

And clinical research has shown that Zinc is vital to healthy skin as well.*⁶
