Quercetin 500mg Capsules with Vitamin D3 800 IU – Immune Support Supplement for Adults – Daily Immune Boosters – Quercetin Immune System Boost, 90 Capsules

I'm glad I found this product. I feel great. Take one a day. I came across them in a health food / pharmacy. Came highly recommended. I now purchase them from Amazon. Do something good for yourself.

Quercetin helps me stay out of allergies c runny nose episodes, this one seems very effective. Speedy delivery so I didn’t run out before getting the next bottle.

Very good dates on product

Used as an immune system boost along with Zinc, vitamins C and D3.

I like that this is the dosage I want, plus the added benefit of D3. I do use more D3 , but less because this adds some. I have been taking Quercetin forgoing on 4 years, and believe it matters!

Harder to find in high quality the quercetin w vitamin d so we’re happy this is our family’s go to. A+ we’ve bought for years now.

Big pills, but easy to swallow. No taste to speak of.

The capsules are easy to swallow. Besides having the Vitamin D3, Quercetin helps your body's cells to absorb zinc, which is one of the immune boosters recommended to fight Covid-19.
