That's a great immune system support during cold and flu season. Quercetin plus zinc plus vitamin C, and your body's protected from unnecessary flu or seasonal colds. Generally, I take 1 capsule per day for 10 days. 1 capsule contains 500 mg of quercetin. The capsules are vegetable and suitable for vegetarians. The capsules are slightly larger in size than average. The capsule shell is transparent, the contents are yellow in color (as in the attached photos). Plastic package with a protective membrane. The package contains 60 capsules. Natural Factors has a favorable price on quercetin.

Quercetin is an excellent anti-inflammatory and antioxidant. I take it regularly and especially at times when I feel like I am coming down with the flu/cold. It helps fights free radicals and is known to reduce risks of infections, heart disease and cancer. I love the formulation of this because it includes bromelain which is a great supplement for reducing pain and swelling, especially of sinuses and gums.
