What is it?

Juice Plus has not been shown to treat or prevent cancer.

Juice Plus is a dietary supplement that contains dried concentrates of fruits and vegetables. It has been studied for its antioxidant and cardiovascular effects, but more studies are needed.

Consumption of juice plus is thought to reduce oxidative stress and DNA damage, and has been associated with a reduction in common cold symptoms. In a study of head and neck cancer patients, it appeared to increase serum micronutrient levels, but had no clinical benefit.

Although there are ongoing clinical studies of Juice Plus in cancer patients, it has not been proven to treat or prevent cancer. Cancer patients should discuss the use of supplements with their physicians. Juice Plus is not a substitute for fresh fruits and vegetables.

What are the potential uses and benefits?

  • To prevent and treat cancer
    Evidence is lacking to support this claim.

What are the side effects?

Some patients reported gastrointestinal distress and hive-like rash in clinical studies.
