Ranked by research evidence. Compare 24 supplements across 36 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 (one moderate, two small) and 2 found neutral effects on reducing oral mucositis severity. Most evidence comes from clinical populations with cancer, particularly head and neck cancer patients undergoing radiotherapy or chemoradiotherapy. The median study duration was 49 days, and the most-studied dose was 5 g of L-glutamine (in one RCT), though dose information was limited across the included papers.
Dose: 5 g daily (single trial) - Low evidence3 studies
Across 3 studies, 2 reported beneficial moderate-sized effects of Streptococcus salivarius K12 on reducing oral mucositis severity, while 1 neutral study found no significant benefit for this strain. The predominant effect size is moderate, supported by a randomized controlled trial in 160 patients with head and neck tumors undergoing radiotherapy. The evidence base is very small, and conclusions should be considered preliminary.
Dose: thrice daily (lozenges) - Low evidence3 studies
Across 3 studies, 2 reported beneficial effects of aloe vera on reducing oral mucositis severity, with effect sizes ranging from small to moderate. One systematic review found neutral effects in pediatric cancer patients, while a meta-analysis and a systematic review in broader cancer populations showed statistically significant benefits. The evidence is limited to clinical populations, primarily adults with cancer, but study durations and doses were not consistently reported.
