Our vegan liquid blend is a highly bioavailable, plant-based zinc that’s water-extracted from certified organic guava leaves. The plant-based formula is all-natural and gentle on your stomach. Unlike most zinc supplements, including zinc gluconate, zinc picolinate, zinc sulfate, and zinc citrate, which are made with synthetic forms of the mineral, the zinc in this formula is naturally bound to plant proteins and amino acids so your body can use it efficiently. To ensure maximum absorption, we recommend taking 1 ml (7.5 mg) twice daily or as directed by your healthcare provider.
