Our zinc gluconate powder is an organic zinc salt produced by reacting gluconic acid with zinc oxide or zinc carbonate. It appears as a white to off-white crystalline fine powder or granular powder, odorless, with a slightly sweet taste and a slightly astringent aftertaste. Compared to zinc sulfate, it has virtually no metallic taste and a much smoother mouthfeel, making it more suitable for use in oral liquids, effervescent tablets, and other products that come into direct contact with the taste buds.
Each batch of product is tested for zinc content, reducing sugars, chlorides, sulfates, heavy metals, especially lead and arsenic, and microbial limits are also checked to ensure compliance with food or dietary supplement standards. In formulation, its high solubility makes it ideal for liquid dosage forms; however, because its aqueous solutions are slightly acidic, care must be taken to avoid its impact on other acid-sensitive ingredients in the formulation, such as certain vitamins or plant extracts.

FAQ
Q: Why is zinc gluconate used in lozenges?
A: Because it releases zinc ions gradually in the mouth without being as harsh or astringent as zinc sulfate. The taste is milder. The texture works with hard candy lozenge bases.
Q: Is zinc gluconate well absorbed?
A: Yes. It is considered one of the well-absorbed organic zinc forms. Studies from the 1980s established its absorption profile. More recent research suggests the difference between organic and inorganic zinc may be smaller when taken with food.
Q: Do you offer private labeling services?
A: Yes, we provide comprehensive private labeling and OEM services, including custom packaging solutions to support your brand development.
Q: How much powder for 10 mg zinc?
A: At 14% zinc content, about 71 mg of powder provides 10 mg elemental zinc.
Q: How's shipping handled?
A: We ship globally by express, air, or sea-pick the speed that matches your plan (and your patience).
