Supplements

In children receiving maintenance chemotherapy for acute lymphoblastic leukemia, the fruit infusion Naqu Fawakeh produced a larger reduction in ALT than silymarin. Both groups also showed lower AST. These are liver-enzyme findings; the abstract does not demonstrate fewer cases of liver injury, better leukemia outcomes or a benefit over placebo.

Keep in mind: There was no placebo group, and the abstract gives no numerical size for the ALT difference. Its brief follow-up and limited safety reporting cannot establish long-term safety.

Among women undergoing assisted reproduction, the pooled trials favored melatonin for clinical pregnancy and some measures of embryo development. Total egg yield did not show a statistically significant difference. These results concern intermediate reproductive outcomes; the abstract reports no live-birth result and does not establish long-term benefits or the best dose.

Keep in mind: This abstract-based summary cannot assess full trial methods. Some secondary results varied considerably across studies, and possible publication bias was suggested for mature egg numbers.

The main analysis did not establish that melatonin reduced delirium in critically ill patients. Including all eligible trials produced a similar result, and mortality analyses also found no clear benefit. These findings leave uncertainty about the true effect; they do not prove that melatonin and placebo have identical effects.

Keep in mind: The abstract does not describe treatment schedules or follow-up lengths. The delirium confidence interval spans lower and higher risk, so this analysis cannot establish equivalent effects.

Saffron did not show a statistically significant benefit for the combined symptom score or for depression, anxiety and fatigue considered individually. A separate self-rated mental-health result was described as improved, but the reported group means do not clearly support that interpretation. The primary null result does not prove that every possible effect is absent.

Keep in mind: The secondary mental-health claim is difficult to reconcile with the group means as labelled. Without the full analysis, the direction and meaning of that result remain uncertain.

The turmeric formulation did not significantly reduce overall muscle soreness compared with placebo after a downhill run. A separate measure of recovery from peak soreness favored turmeric, as did some muscle-function measures in males. These mixed findings support distinguishing recovery from overall soreness, rather than describing the supplement as broadly effective.

Keep in mind: This abstract describes a brief test of one formulation, primarily analyzed in males. It does not establish lasting benefits, and exploratory female outcomes cannot support the same conclusions with equal confidence.

The pooled estimates favored caffeine plus taurine over either ingredient alone for anaerobic capacity and reaction time. Findings for endurance and physiological measures were less consistent. Heart rate showed no credible differences across conditions, which does not prove identical effects. The results support a limited performance finding, with practical relevance still uncertain.

Keep in mind: This abstract-based account lacks participant characteristics, doses, assessment timing and safety outcomes. It therefore cannot establish which settings the findings apply to or the safety and overall value of commercial energy drinks.

The review found a small average improvement on the MMSE cognitive test with omega-3 supplementation. That result does not establish prevention of dementia or a noticeable improvement in daily functioning. Analyses did not find significant associations between dose or treatment duration and cognitive outcomes, leaving an optimal regimen unresolved.

Keep in mind: The abstract does not specify comparison treatments, supplementation durations or whether score changes mattered in daily life. Results varied moderately across studies, and this abstract-based summary cannot assess the underlying trials in detail.

In men following a resistance training program, the extract group showed greater bench press and squat strength gains than placebo among participants without prior training experience. Other strength and blood-marker changes were also reported. The abstract does not quantify the extra strength gained or establish that changes in blood markers meant faster functional recovery.

Keep in mind: The methods and conclusion give conflicting dosing descriptions. The abstract reports statistical significance without effect sizes or safety results, so benefit size and tolerability remain unclear.

The combination supplement produced greater improvements in explosive upper-body strength tests than the comparison groups during race-pace training. Handgrip and medicine-ball throw changes were small and did not differ significantly between groups. These results concern specific strength tests in elite male swimmers; they do not establish faster swimming or a gut-microbe mechanism.

Keep in mind: The abstract gives no participant count, supplement doses or numerical effect estimates. Microbiome and metabolite testing were not performed, leaving the proposed gut mechanism untested.

Magnesium supplementation produced modest average reductions in systolic and diastolic blood pressure compared with placebo. The review reported larger reductions in participants taking blood-pressure medication for hypertension and in those with low magnesium. Results varied substantially across studies, and the analysis did not identify a dose–response relationship or establish an optimal dose.

Keep in mind: High variation between trials limits how well the pooled average describes any particular group. This abstract-based summary cannot establish cardiovascular benefits beyond the measured blood-pressure changes or resolve the best supplementation strategy.

Vitamin D improved bone density at the femoral neck in kidney transplant recipients, but fracture incidence and lumbar-spine bone density did not differ significantly from placebo or no treatment. Excess blood calcium was more likely with supplementation. The review does not establish that better bone measurements led to fewer fractures.

Keep in mind: More than half the studies had high risk of bias. This summary uses only the abstract, which does not identify a preferred supplement type or dose.

Collagen added to resistance training produced greater increases in patellar tendon size and peak rate of force development than placebo. Maximum force and thigh-muscle thickness increased without a significant difference in improvement between groups, while jump height did not change significantly. These results concern laboratory measures in a specific athletic population.

Keep in mind: The abstract covers a small, narrowly defined athletic sample and a short training period. It does not establish whether tendon changes reduce injuries or improve hockey performance.

The combined supplement improved several physical test results compared with placebo and produced the highest wrestling-test throw count among the tested conditions. Cognitive results also favored the combination on some comparisons. The trial offers a short-term signal in elite male wrestlers. It does not establish better competition results or safe long-term use.

Keep in mind: Only 12 wrestlers were studied, and effects were measured during acute testing. The abstract supplies significance tests but no performance effect sizes or confidence intervals; its anxiety percentages also lack a clear definition.

The review found better global cognitive scores with B vitamin supplementation, but the estimated benefit depended strongly on which studies were included. Removing statistical outliers and single-blind studies left a very small effect that the authors rated as high certainty. This is a finding about cognitive test performance, not direct evidence of dementia prevention.

Keep in mind: The full pooled analysis had very low certainty and substantial variation between studies. The higher-certainty estimate excludes selected studies, and the abstract does not establish an improvement in everyday functioning.

Runners given a single high dose of vitamin D before an ultramarathon had a larger immediate rise in a bone-turnover marker than runners given placebo. This suggests a short-term change in bone metabolism under extreme exertion. The study does not establish stronger bones, fewer injuries or a performance benefit from supplementation.

Keep in mind: The trial included a small, specialized group of male runners and measured short-term blood markers. The abstract provides no evidence about lasting skeletal benefits or clinical safety.

This review describes possible cognitive benefits from lion's mane, but the abstract combines human studies with laboratory and other evidence. It reports a change in a cognitive screening score without enough detail to judge benefit relative to a comparison group. The broad claims about cancer, gut health and mood cannot all be treated as demonstrated human benefits.

Keep in mind: The review notes that side effects were commonly unreported. Stomach discomfort, headache and allergic reactions were listed as possible harms, so the abstract cannot establish a reliable safety profile.

The pooled trials reported lower blood pressure and improvements in several metabolic and inflammation markers with spirulina compared with placebo or control. These are measurements related to cardiovascular health, rather than direct evidence about heart attacks or survival. The abstract does not establish that spirulina prevents cardiovascular disease or clarify its safety.

Keep in mind: This abstract-based assessment lacks treatment durations, doses, adverse-event results and confidence intervals. Those omissions limit judgments about the persistence, practical importance and safety of the reported changes.

The review ranked dietary supplements according to changes in bone turnover markers in postmenopausal women. Different supplements ranked highest for different markers, so the abstract does not identify a single overall winner. These biomarker rankings do not establish fewer fractures, stronger bones or slower progression of osteoporosis in everyday clinical care.

Keep in mind: This abstract-based assessment has no treatment durations, effect sizes or uncertainty intervals to examine. The reported outcomes are biomarkers, so the authors' suggestion about limiting osteoporosis progression remains unproven here.

Iron supplementation was linked to improvements in selected symptoms and cognitive outcomes among people without anemia, but results differed across outcomes and analyses. Randomized trials did not show improvement in depression or attention. The lack of detected effects after excluding iron-deficient participants limits claims of benefit for people with adequate iron.

Keep in mind: The abstract does not provide treatment durations, dosing details, confidence intervals, or adverse-event results. It also does not describe comparator arrangements within the pre-post studies, limiting interpretation of those analyses.

Cognitive test scores and depression symptom scores improved within the supplement group. Serotonin increased, while the authors reported no effects on anxiety or the other blood markers. The abstract gives no clear between-group estimate for these changes, leaving uncertain how much improvement was attributable to supplementation rather than change over time.

Keep in mind: This was a small, short trial. The abstract does not report a treatment-versus-control effect estimate with uncertainty, and improvements within a group alone do not establish a supplementation benefit.

Creatine combined with resistance training produced statistically significant average improvements in bench or chest press strength, squat strength, vertical jump and Wingate peak power. Handgrip and leg press results were not statistically significant. These findings concern measured exercise performance; they do not show a uniform effect across strength tests or all adult populations.

Keep in mind: Trial durations and confidence intervals for the reported estimates are absent from the abstract. The authors also identify a need for better-powered trials involving women and older adults.

The review describes favorable changes in lean muscle mass, strength and physical performance when leucine-enriched whey protein was combined with resistance training in older adults with sarcopenia. The abstract does not quantify these changes or identify the comparisons behind them, leaving uncertainty about the supplement's separate contribution and the practical size of any benefit.

Keep in mind: The abstract omits study counts, participant totals, effect estimates and comparator details. Its inclusion of several study types also makes it difficult to judge how each contributed to the conclusions.

The pooled animal experiments found smaller tumor volumes with curcumin than with control conditions. This supports further investigation in experimental lung cancer models, but it does not establish that curcumin treats or prevents lung cancer in humans. The accompanying analyses suggest possible biological targets without demonstrating a clinical benefit from acting on them.

Keep in mind: The efficacy evidence comes from animals. The abstract provides no pooled tumor-volume effect size, treatment duration or dosing details, limiting interpretation of the size and consistency of the experimental result.

The adjusted analysis did not show a statistically clear overall shortening of intensive-care or hospital stays with melatonin or drugs acting on melatonin receptors. Some patient subgroups had more favorable results, but the review judged the overall evidence very uncertain. These findings do not establish a routine benefit for adults admitted to intensive care.

Keep in mind: Results varied substantially between studies, and the review rated the evidence as very low certainty. The subgroup findings do not establish that all intensive-care patients benefit, while nonsignificant overall results do not prove no effect.
