Formulation Notes

V-Guard 2 is a Designer Food formula created by research scientists, Durk Pearson & Sandy Shaw to provide natural support for healthy immune function.

This product contains vitamin C (reported to protect against excessive immune stimulation of inducible nitric oxide), vitamin D (levels of which are low in many people of all ages, but especially in the elderly and in those who stay completely out of the sun, or who use sunscreens), the flavonoid quercetin (found in vegetables and fruits, and especially in apples, cranberries, blueberries, and onions, as well as black tea, red wine, and various fruit juices), green tea extract (90% polyphenols, 50% of which is EGCG), N-acetylcysteine (which increases the amount of intracellular cysteine needed to maintain high levels of reduced glutathione), resveratrol (which has been shown to inhibit PKC (protein kinase C, an intracellular signaling molecule) activity and its dependent pathways), and selenium, a cofactor in glutathione peroxidase, a biologically powerful antioxidant.

Powerful antioxidant immune supplement to support immune function & protect your health.
