B12 IssueWheatgrass proponent Schnabel claimed in the 1940s that "fifteen pounds of wheatgrass is equal in overall nutritional value to 350 pounds of ordinary garden vegetables",^[2] a ratio of 1:23.^[13] Despite claims of vitamin and mineral content disproportional to other vegetables, the nutrient content of wheatgrass juice is roughly equivalent to that of common vegetables (see table 1).

Wheatgrass is also thought to be superior to other vegetables in its content of Vitamin B₁₂, a vital nutrient. Contrary to popular belief, B₁₂ is not contained within wheat grass or any vegetable, rather it is a byproduct of the microorganisms living on plants.^[14]. If plants are washed prior to consumption the water soluble B₁₂ will be removed making most plants unreliable sources of B₁₂.^[15]
