Some U.S. chemical associations recognize only 13 vitamins. However, the International Union of Pure and Applied Chemistry (from the International Union of Biochemistry) has identified 19 vitamins, and the Japanese Vitamin Academic Society has identified 17 vitamins.

Vitamin P and vitamin F are considered citrus bioflavonoids and essential unsaturated fatty acids, respectively. Vitamin B12 is generally believed to come only from animal sources; however, independent analyses from Irvine Analytical Laboratories, as well as from the Resource Research Association, Office of Science and Technology, and Japan Food Analysis Center, indicate that green barley leaves contain B12.

There is not a standard method to analyze enzyme activities. Superoxide dismutase (SOD) has been used to measure enzyme activities. Lab analyses indicate that green barley leaf extract contains active SOD. The presence of active SOD in green barley leaf extract may indicate that other common green grass enzymes are found in active conditions.
