Ranked by research evidence. Compare 25 supplements across 43 papers from the biomedical literature, with effect direction, evidence strength, and dose range for each.
Top picks by evidence
- Moderate evidence5 studies
Across 5 studies, 3 reported beneficial effects of L-glutamine on reducing oral mucositis severity, with effect sizes ranging from small to moderate. The evidence includes a meta-analysis and a recent RCT showing statistically significant benefits, while 2 studies (both systematic reviews or RCTs) found neutral effects. The median study duration was 49 days (reported in 1 study), and the most studied population is cancer patients undergoing treatment.
- Low evidence4 studies
Across 4 studies, 2 reported beneficial effects of honey on reducing oral mucositis severity, with effect sizes ranging from small to moderate. The median study duration was 49 days, indicating effects typically observed at 7+ weeks. Evidence is strongest in cancer patients undergoing radiotherapy or chemotherapy.
- Low evidence3 studies
Across 3 studies, 2 reported beneficial moderate-sized effects of Streptococcus salivarius K12 on reducing oral mucositis severity, while 1 showed a neutral effect. The strongest evidence comes from a single randomized controlled trial (RCT) in 160 patients with head and neck tumors undergoing radiotherapy, where the probiotic significantly reduced the incidence of severe oral mucositis (36.6% vs 54.2%, p=0.035). Effects appear moderate in magnitude, but the evidence base is limited and findings are mixed.
Dose: thrice daily (lozenges)

- LowAloe VeraAcross 3 studies, 2 reported beneficial effects of aloe vera on reducing oral mucositis severity, with effect sizes ranging from small to moderate, while 1 neutral review found no significant benefit. The beneficial findings come from a meta-analysis (2011) and a systematic review (2023), both in clinical cancer populations. The evidence base is small and preliminary, with no consistent dose or form data available.2 beneficial1 neutral3 studies
- Lowplantain leafAcross 3 studies, 2 reported beneficial moderate-sized effects of plantain leaf on reducing oral mucositis severity in cancer patients, while 1 small neutral trial found no significant benefit. The predominant effect size is moderate in systematic reviews, but the only RCT showed a small, non-significant effect. No consistent dose or form data were extracted. The median study duration was 14 days (from 1 study).2 beneficial1 neutral3 studies
- LowManuka HoneyAcross 3 studies, 1 showed a beneficial moderate effect of manuka honey on reducing oral mucositis severity, while 2 found no significant difference (neutral, small effect). The evidence is based on head and neck cancer patients receiving radiotherapy, with doses ranging from 5 ml to 20 ml four times daily. The only study reporting duration had a 42-day treatment period.1 beneficial2 neutral3 studies
