Doctor Strength – Zincberry Shield

Immune Support Lozenges with Zinc, Elderberry & Vitamin D3*

Defend your immune system year-round with the synergistic power of zinc, elderberry, and vitamin D3. Doctor Strength’s Zincberry Shield delivers targeted support for the throat, sinuses, and upper respiratory tract—all in a convenient, great-tasting lozenge.*

The Science Behind Zincberry Shield

• Zinc (as Citrate & Gluconate): An essential trace mineral that helps immune cells function at their best. Zinc supports healthy lung function, clear skin, and overall vitality.*
• Elderberry (Sambucus nigra): Used for centuries in traditional herbalism and supported by modern research, elderberry provides powerful antioxidant compounds (polyphenols) that promote upper respiratory and sinus health.*
• Vitamin D3 (Cholecalciferol): Known as the “sunshine vitamin,” vitamin D3 is critical for immune balance. It activates macrophages and T-cells, helping the body stay resilient while also supporting bone and cardiovascular health.* 

Unlike many zinc and elderberry lozenges on the market that contain added sugars, Zincberry Shield is naturally sweetened with xylitol, stevia, and honey powder. This makes it a smart choice for daily immune support without compromising taste or wellness.
