Pure Encapsulations Quercetin UltraSorb
You push your body through high-volume training weeks, race-day efforts, and back-to-back sessions that pile up oxidative stress and test your immune system. Quercetin — a powerful plant flavonoid and natural antioxidant — can help your body fight back. The problem? Standard quercetin supplements barely absorb, so most of what you take never reaches your cells.
Your Antioxidant Defense Just Got 20x Stronger
Pure Encapsulations Quercetin UltraSorb solves that with QuerceFit®, a patented quercetin-phospholipid complex clinically shown to absorb 20 times better than regular quercetin.
Absorbs 20x Better Than Standard Quercetin – QuerceFit® pairs quercetin with sunflower-derived phospholipids in a 1:1 ratio, protecting it through your digestive tract and delivering it where your body actually needs it. You get dramatically more from every capsule.
Supports Your Immune System Under Training Stress – Hard training suppresses your immune system, and that's when you're most vulnerable. Quercetin helps stabilize mast cells (the immune responders that trigger inflammation and allergic reactions), keeping your immune defenses strong through heavy training blocks and race season.
Accelerates Recovery and Cellular Renewal – Quercetin activates SIRT1, a protein that triggers autophagy, your body's natural process of clearing out damaged cells and rebuilding fresh ones. It also boosts glutathione, your body's master antioxidant, helping neutralize the oxidative damage that comes from pushing hard day after day.
How to Use Pure Encapsulations Quercetin UltraSorb
Take 1 capsule, 1–2 times daily, with meals.
