3 year shelf life guaranteed (while unopened)
Results in just 30 seconds.

Great for biology lab & science fair experiments.

You can also build an actual Ascorbic Acid/Vitamin C chemical structure model to show in class, on-line or at science fair.


These test strips are calibrated with vitamin C dissolved in water which you can also do with store bought tablets. This is useful for controlled science experiments and for comparing against different fruit & vegetable juices or urine.

Vitamin C levels are shown as percentages where 0.01% equals 10mg/100ml & 0.1% equals 100mg/100ml. A 1000mg vitamin C tablet dissolved in 1000ml of water should give you a reading of 0.1%.

Fruit juices that claim 100% or more of recommended daily allowance (RDA) may read higher than the strips can measure so you might need to dilute the juice. e.g. 9 parts water & 1 part of juice will reduce the concentration to 1/10 the original.

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.
