Preventive Effect of Probiotics on Oral Mucositis Induced by Cancer Treatment: A Systematic Review and Meta-Analysis
International journal of molecular sciences (2022) · Meta analysis · n=708
Three trials using Lactobacilli-based probiotics reported that the incidence of oral mucositis in the probiotic group was significantly low (risk ratio [RR] = 0.84, 95% confidence interval [CI] = 0.77−0.93, p = 0.0004).

Raspberry Leaves and Extracts-Molecular Mechanism of Action and Its Effectiveness on Human Cervical Ripening and the Induction of Labor
Nutrients (2023) · Review
The majority of women apply raspberry leaves during pregnancy to induce and ease labor.
A Review on Berry Seeds-A Special Emphasis on Their Chemical Content and Health-Promoting Properties
Nutrients (2023) · Review
A different part of the plant: berry seeds, not the leaf. Raspberry leaf is dosed as 1-2g dried leaf as tea for uterine and menstrual use, and this paper reviews the chemical content of berry seeds. Read it as species-level context, not as leaf evidence.
Phenolic Composition, Mineral Content, and Beneficial Bioactivities of Leaf Extracts from Black Currant (Ribes nigrum L.), Raspberry (Rubus idaeus), and Aronia (Aronia melanocarpa)
Nutrients (2020) · Review
Narrative review of the phenolic compounds and minerals in leaves of black currant, raspberry and aronia, not raspberry alone.
Both points come from one phase II RCT in 198 adults with knee osteoarthritis (PMID 35799169), which gave 200 mg or 400 mg of leaf extract daily for 12 weeks. The primary endpoint, WOMAC pain, did not differ from placebo at either dose. Walking pain on a VAS fell more than placebo at 400 mg only, so 200 mg is plotted as no effect. Doses above 400 mg were not tested, and a single trial cannot establish an optimal dose or a safety ceiling.
AI-estimated from published studies. Interpret as directional guidance.
Probiotics has a higher evidence score (9/10 vs 4/10) and wins in 3 of 3 categories.
Both Probiotics and Raspberry Leaf score equally (60) for support mood.
No documented interaction was found in the data searched. This does not establish that this exact combination is safe.
The honest tier list — proven staples vs situational vs mostly marketing. The hub the other guides feed into.
On Ozempic/Wegovy/Mounjaro? What actually helps — muscle preservation, GI relief, nutrient gaps (no upsell).
Saffron, EPA omega-3, SAMe have real adjunct evidence — but these aren’t a substitute for care, and some interact dangerously.
