Immune support supplement – Quercetin complements vitamin C’s immune-friendly benefits. So, we’ve combined our highly absorbable quercetin with vitamin C to help encourage healthy immune system function.
Quercetin and vitamin C for a healthy ticker – Vitamin C can help support certain aspects of heart health. And we added quercetin to help protect from oxidative stress.
Highly absorbable quercetin – We combined quercetin with fibers from fenugreek seeds to help increase bioavailability. In a clinical study, quercetin formulated with fenugreek fibers was up to 62x more available than traditional quercetin.
Ingredients matter – We use the finest raw ingredients chosen for quality and purity. The majority of our products are non-GMO, gluten-free and manufactured in the USA with globally sourced ingredients, and a Certificate of Analysis is available for each.
Live your healthiest life – We believe the answers to a healthier life are within reach, and that scientific research is the key to getting us there. That’s why so many of our formulas feature specific ingredients and amounts based on scientific studies.
