This color chart should be used when testing only for ascorbic acid (Vitamin C). Use it as a reference before testing fruits and vegetabes. You can also use it to establish a baseline for any experiments where you add citric or other naturally occurring acids.
The number of strips (100) per pack is approximate.
The guaranteed shelf life is 3 years if the pack is kept sealed & stored in a cool dark place. 5 years is typical but test against a calibrated tablet to be sure.
Works with any form of ascorbic acid; eg. calcium ascorbate or sodium ascorbate.

I purchased this product to monitor urine levels of ascorbic acid after beginning Liposomal Vitamin C. These test strips are an indispensable tool to verify that, yes indeed, Liposomal Vitamin C greatly increases blood levels of Vitamin C.
Anyone in doubt on the subject of Liposomal Vitamin C can easily and inexpensively confirm for themselves how effective this method of administration actually is. I heartily recommend these test strips to anyone considering Liposomal Vitamin C as an addition to their daily diet. Liposomal Vitamin C works and these test strips confirm it.
