Superior Source Advanced Zinc, Vitamin D3, 60 MicroLingual® Instant Dissolve Tablets

Superior Source Advanced Zinc with Vitamin D3 is a MicroLingual® instant-dissolve tablet designed to provide zinc and vitamin D3 in a convenient under-the-tongue format. It contains 25 mg of zinc from oxide and gluconate sources, along with 125 mcg (5,000 IU) of vitamin D3 as cholecalciferol, a dosage that aligns with common supplemental levels for immune support. The manufacturer notes that zinc is involved in over 300 enzymatic processes and has been studied for its role in recovery from cold symptoms, while vitamin D3 is included for added health protection.

This product stands out due to its MicroLingual® technology, which allows the tablets to dissolve quickly under the tongue without water, potentially enhancing absorption. It uses natural cherry flavor and stevia leaf extract for taste, without artificial sweeteners or preservatives. The formulation includes lactose as an ingredient, so it contains milk allergens. Available in a 60-count package, it is also Non-GMO verified, reflecting a focus on clean labeling within its category.
