Part of our Capsules range, manufactured and exported by Arizone International LLP.
Quercetin Capsules are dietary supplements built around quercetin, a plant flavonoid found in everyday foods such as onions, apples, berries, capers and leafy greens. Over the last few years quercetin has moved from a niche ingredient to a regular part of antioxidant, seasonal wellness and healthy-ageing ranges, and many brands now want it as a stand-alone capsule or as part of a combination.
Arizone International manufactures and exports Quercetin Capsules from India for private label, contract manufacturing, wholesale and bulk buyers. You choose the form of quercetin, the strength per capsule, any partner ingredients and the pack; we handle sourcing, filling, testing and export paperwork.
Quercetin belongs to the flavonol group of flavonoids. In plants it usually occurs bound to sugars (for example as rutin or isoquercitrin), while supplement-grade quercetin is the free form, most often supplied as quercetin dihydrate. Commercial material is commonly extracted from the flower buds of Sophora japonica (the Japanese pagoda tree), which are naturally rich in rutin, although other plant sources are also used.
The raw material is a fine yellow powder with a slightly bitter taste. It does not dissolve well in water, which is why some brands choose enhanced forms such as phytosome or other delivery-focused versions, or pair quercetin with ingredients like bromelain or vitamin C in the same capsule.
Label claims should follow the rules of the market where the product is sold. We can help you keep the wording within what your target market allows.
The serving size depends on the form and strength of quercetin in the capsule, so it should always follow the finished product label. Quercetin can interact with some prescription medicines, so labels should advise people taking medication, and women who are pregnant or breastfeeding, to speak to a healthcare professional before use.
Every batch is made to an agreed specification and supplied with a certificate of analysis. Typical checks include identity and quercetin assay by HPLC, loss on drying, heavy metals, microbiology, residual solvents where relevant, and capsule weight variation and disintegration. For EU and UK buyers we can also share pesticide and contaminant reports on request.
Ask whether the quercetin is anhydrous or dihydrate, because the dihydrate carries about 10% water and gives a slightly lower quercetin content per milligram. State clearly on the label which form is used and how much quercetin each serving provides.
Quercetin is a yellow powder that can stain equipment and capsules, so opaque or coloured shells often give a cleaner look. Keep bottles closed and away from light and heat to protect the product.
