Aller-Shield

Aller-Shield is an advanced, broad-spectrum nutritional formula providing comprehensive support for seasonal environmental challenges.* The select nutrients in this formula – Vitamin C, Vitamin D3 and Zinc – have been chosen for their synergistic ability to offer protection by supporting the body’s immune response.*

Key ingredients in Aller-Shield include Quercetin, Bromelain and Nettle extract, which have been found to help promote healthy mucus viscosity and provide histamine support.* Additionally, N-Acetyl L-Cysteine (NAC) is a unique form of the amino acid l-cysteine, which has been found to support healthy tissue levels of glutathione (GSH).
