CHK Nutrition will begin using the supplement industry standard of “BEST USED BY DATE” on products. When we do this, an independent third-party lab is used to verify the “BEST USED BY DATE” that will be used.
The first product that has been moved to “BEST USED BY DATE” is CysReplete LT. Testing on Lot # 4127171 verified the potency and efficacy of the label ingredients to support a “BEST USED BY DATE” of June 2028.
