Questionable expiration date on bottle
The product was expired by the date stamped on the bottom but it was covered up by a sticker with New date to show it wasn't expired. This makes me very skeptical to use it.

Is this gentle on the stomach like a buffered version?

Is this kosher? What is the gelatin source?
Annemarie H

Best Answer:  EnteQuercetin is a plant flavonol from the flavonoid group of polyphenols. It is found in many fruits, vegetables, leaves, seeds, and grains; red onions and kale are common foods containing appreciable amounts of quercetin. Quercetin has a bitter flavor and is used as an ingredient in dietary supplements, beverages, and foodsr an answer to this question.

What’s the Ascorbic acid derived from?
Heather G

Best Answer:  You need to contact Vitamin Shoppe directly to determine exactly what their source is. Noted it states Citrus Free. It can still come from strawberries, tomatoes, broccoli and other sources. They should have your exact answer. Post the results. Thanks.

Vince M
The capsules are yellow with some redish spots. Is that normal?
