Keystone RX - Hist Immune

Product Details
expand_less

Hist Immune 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 Hist Immune 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).*

Seasonal discomfort is caused by an overreaction of the immune system to harmless substances it misinterprets as a threat. To vanquish these perceived invaders, the immune system dials up the inflammation dial, launching a full-blown attack against nothing. In the process, the pro-inflammatory protein complex NF-kappa B is activated. It tells mast cells to release their contents of histamine, which impacts the nose, lungs, and eyes.
