FAQ
Q:What is onion extract?
A:Onion extract is a concentrated botanical powder made from Allium cepa, mainly the dry outer skins, which hold the highest flavonoid levels in the bulb. While naturally co-present onion polyphenols remain in the matrix. Food-grade grades support antioxidant, cardiovascular, and immune wellness product concepts.
Q:Why source quercetin from onion rather than isolated quercetin?
A:Quercetin from onion arrives inside a whole-food matrix of co-extracted polyphenols and fiber remnants, which formulators describe as a cleaner-label flavonoid story than a single isolated molecule. Onion skin extract is also one of the most economical natural sources of quercetin, because the outer tunics concentrate the flavonoid during bulb growth.
Q:How is onion extract used in supplements?
A:Onion extract typically appears in daily capsules and tablets at 100 to 500 mg per serving, delivering roughly 10 to 50 mg of quercetin depending on the standardization chosen. It blends with vitamin C, zinc or green tea extract for antioxidant and immune positioning, and its fine powder also suits pressed tablets and powder sachets without strong flavor impact.
Q:Is onion extract safe and suitable for daily use?
A:Onion is a common food consumed daily around the world, and food-grade onion extract is produced with ethanol or water extraction only. Every lot is tested for heavy metals, microbiology, pesticide residues and quercetin content. Customers still complete their own safety review for target markets, and we supply the documentation needed for registration files.
Q:What documentation and certifications do onion extract suppliers provide?
A:Every batch ships with a certificate of analysis covering identity, quercetin assay, heavy metals, pesticide residues and microbiology, together with an MSDS, allergen statement and export paperwork. Our Xi'an facility holds FSSC 22000, Kosher, Halal and SC certifications. Third-party verification can be arranged through an accredited laboratory you nominate.
