Fish oil for neuropathy: a chemotherapy trial cannot set a general dose

A small trial reported fewer cases of paclitaxel-related neuropathy with omega-3 supplementation. It does not establish a dose for diabetic neuropathy, nerve compression or unexplained nerve symptoms.

The intervention accompanied a specific chemotherapy

Women receiving paclitaxel for breast cancer were randomized to omega-3 capsules or placebo during chemotherapy and for one month afterward. The reported analysis included 30 active-treatment and 27 placebo participants. [1]

Seventy percent of the omega-3 group and about 41% of controls did not develop peripheral neuropathy. The incidence comparison was significant; the severity comparison was described as a nonsignificant trend. [1]

Prevention in one setting is not treatment for every neuropathy

The trial was small and examined prevention around paclitaxel exposure, not reversal of longstanding neuropathy from other causes. Its capsule regimen is not a personal dosing recommendation. [1]

Funding and conflicts were not established from the abstract. People receiving chemotherapy should review supplements with their oncology team, since the overall treatment context matters. New numbness, pain or weakness also requires assessment of its cause rather than assuming this trial identifies an appropriate supplement. [1]

Check whether the nerve problem has the same cause

Imagine a trial concerns a chemotherapy side effect. Applying its result to a compressed nerve would change the mechanism, population and treatment question.
