Overview
Solgar's Quercetin Complex pairs quercetin with Ester-C for immune and antioxidant support, packaged as 100 vegetable capsules good for 50 servings at two capsules per serving.
Quercetin and vitamin C are frequently combined because quercetin is thought to work alongside vitamin C in immune-related pathways, and Solgar uses Ester-C, a buffered vitamin C form marketed as gentler on digestion than standard ascorbic acid. No milligram amounts were included in the data here, so shoppers wanting exact quercetin or vitamin C dosing should check the label directly.
- 100 vegetable capsules, 50 two-capsule servings
- Combines quercetin with Ester-C vitamin C
- Non-GMO and vegan
- Gluten and dairy free
Who it's for
Aimed at buyers who already know they want a quercetin and vitamin C combination and prefer a buffered, stomach-friendly vitamin C source. Not the pick for someone who wants a single-ingredient quercetin or plain vitamin C product without the added complex.
