Preparation procedures can influence ingredient safety. For instance, removing seeds from apples is recommended because they contain cyanogenic glycosides, which can be toxic when ingested. Wash greens in a solution of baking soda and water to eliminate some of the pesticides. Peeling non-organic fruits and vegetables is wise, as juicing the surface concentrates the residues as well. These matters ensure that even borderline ingredients are made safer.

Individuals with specific health conditions require special precautions. People with sensitive kidneys should avoid high-oxalate greens completely. Diabetics should avoid all fruit, except lemon. Individuals taking certain medications should avoid vitamin K-containing ingredients, such as kale. Children need diluted juices without strong herbs.

The program of safety in juicing practice is established in the following manner: First, rotate greens weekly to prevent Mineral build-up. Second, test new materials in small amounts. Third, compound juices with fibrous foods. Fourth, watch body reactions in order to modify the recipes. Good quality material is the difference between benefit and danger in practice.
