What makes this deal worth a look

  • 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.

  • Quality ingredients – The majority of our products are non-GMO, gluten-free and manufactured in the USA with internationally sourced ingredients.

  • Science matters – Expert formulators design our supplement formulas, and a Certificate of Analysis is available for every Life Extension product.
