Tart Cherry Juice as a Dietary Supplement for the Prevention of Paclitaxel-Induced Neuropathy
This is a single institution phase II randomized study evaluating the potential benefits of a supplement, tart cherry juice at high- versus low-doses, to prevent taxane induced peripheral neuropathy in breast and ovarian cancer patients undergoing paclitaxel chemotherapy.

Eligible participants enrolled onto the study will be block randomized in a 1:1 allocation to either the tart cherry juice high-dose group (Arm 1) or the tart cherry juice low-dose group (Arm 2).
