## Questions & Answers

**Q: What does quercetin do?**
A: Quercetin is a flavonoid (plant pigment) that’s been shown to help support a healthy immune response and already-healthy blood pressure by promoting endothelial health. It can also help protect against oxidative stress.

**Q: Is Bio-Quercetin the same as quercetin?**
A: No. Quercetin is a traditional plant compound that’s not always easy for the body to absorb. Bio-Quercetin is our special combo of quercetin with fenugreek seed fibers that helps make quercetin up to 62x more bioavailable than traditional quercetin.

**Q: Why take vitamin C and quercetin together?**
A: Quercetin complements vitamin C, inhibiting oxidative stress to support heart health and immune function.

**Q: Is it OK to take quercetin every day?**
A: Yes, in general, it’s safe to take quercetin daily. Always follow the instructions on the label. If you’re concerned about adding quercetin to your routine, speak with your doctor to see what’s best for you.
