What is MAXI/GUARDs shelf life?
Before mixing, MAXI/GUARD has a shelf life of over 3 years. However, as with any colored product, direct sunlight should be avoided. Unmixed product may be displayed on product shelves in the clinic merchandising area. After mixing the Vitamin C, you have a shelf life of approximately 6 months in a cool, dark cabinet, or 1 year in the refrigerator. MAXI/GUARD features a unique product freshness indicator through natural color change. You have a fresh, efficacious product as long as the color remains blue or green. A brown or yellow color is your indication that the product, although safe, is no longer fresh and efficacious.
