#2 BEST IMMUNE PICK
Luma Nutrition’s Quercetin + Bromelain combines a powerful dose of quercetin with the anti-inflammatory enzyme, bromelain. This unique enzyme found in pineapples breaks down a range of proteins, including many involved in the inflammatory response and blood clots. It also inhibits key signalling chemicals that drive inflammation. These abilities have potential effects ranging from cardiovascular disease prevention to allergy relief and faster wound healing.
Better yet, bromelain may even increase the rate of tendon cell regeneration, partly through its anti-inflammatory properties. As a result, you may enjoy a lower risk of sports injuries. Quercetin benefits athletes by supporting improved performance, making the two ingredients a winning combination.

Designs for Health’s Quercetin + Nettles combines the anti-inflammatory power of quercetin with nettle (Urtica dioica).

As an astringent and anti-inflammatory, nettle can prevent symptoms of allergies such as redness and swelling, too.

#6 BEST IMMUNE PICK
Life Extension’s Bio-Quercetin features a vegetarian-friendly quercetin phytosome formulation, with the best value for money at 27 cents per dose. The company also shows they’ve done their homework, too, with a list of several research papers demonstrating quercetin’s benefits. True to Life Extension’s goal of enhancing longevity and taming aging, quercetin may make cells biologically younger by helping them remove old, damaged components that harm the rest of the cell. However, it only contains a 10mg dose of quercetin (29mg as part of the phytosome complex), a small fraction of that found in other brands.
