This revision included 23 studies, 16 of them (69.6%) qualified as excellent and 7 (30.4%) as good at the methodological level based on the punctuation in the PEDro scale.
Polymer-based oral rehydration solution for treating acute watery diarrhoea
The Cochrane database of systematic reviews (2016) · Meta analysis · n=4284
Polymer-based ORS may decrease mean stool output in the first 24 hours by 24 mL/kg (mean difference (MD) -24.60 mL/kg, 95% CI -40.69 to -8.51; one trial, 99 participants, low quality evidence).

We found no statistically significant difference in the need for unscheduled intravenous infusion.
Travellers' diarrhoea
BMJ clinical evidence (2015) · Systematic review
BMJ Clinical Evidence systematic review of 24 studies on treating acute mild to moderate travellers' diarrhoea in adults, with a GRADE rating for each treatment.
The points come from one crossover dose-response trial in 10 healthy men given 70, 140 or 280 mL of concentrated beetroot juice, containing 4.2, 8.4 and 16.8 mmol of nitrate (about 260, 521 and 1,042 mg), 2.5 hours before cycling (PMID 23640589). 70 mL did not change the exercise responses compared with nitrate-depleted placebo. 140 and 280 mL extended time to task failure in severe cycling by 14% and 12%, and the higher dose gave no further improvement, so the curve is flat above 521 mg. The abstract does not report tolerability, so no ceiling is set. The curve rests on acute single doses in young men and cannot show effects of daily use, in women, in older adults or in trained athletes.
AI-estimated from published studies. Interpret as directional guidance.
Beetroot has a higher evidence score (7.5/10 vs 7/10) and wins in 3 of 3 categories.
For speed up recovery, Electrolyte Complex has a higher relevance score (95 vs 60).
No documented interaction was found in the data searched. This does not establish that this exact combination is safe.
Caffeine, citrulline, beta-alanine, creatine — the ingredients that work, at clinical doses (vs fairy dusting).
On Ozempic/Wegovy/Mounjaro? What actually helps — muscle preservation, GI relief, nutrient gaps (no upsell).
Who actually needs electrolytes (and who doesn’t), what matters (sodium), and LMNT vs alternatives.
