A low dose of lemon myrtle supplementation was reported to increase hypertrophy measures during low-load resistance training in older adults. Again Backhousia citriodora, not Citrus limon.

Systematic review, 2024

Across exercise studies, magnesium was linked to less muscle soreness and better recovery, with people training hard possibly needing 10 to 20 percent more than sedentary people.

Meta-analysis, 2025

In a network meta-analysis of 19 trials with 1,658 participants, biotin-containing preparations were among the supplements linked to greater hair density, though most individual trials were small.

Across 10 trials, magnesium reduced how often severe recurring headache attacks struck.

Systematic review, 2025

A review of beetroot juice trials in older adults reported improvements in physical performance measures, with cognitive findings less consistent.

Randomised trial, 2025

Lemon myrtle extract taken alongside low-load bodyweight resistance training was reported to increase muscle size measures in older adults relative to training alone. Lemon myrtle is Backhousia citriodora, a different plant from lemon fruit.

Systematic review, 2026

Long-term plant versus animal protein supplementation was examined for body composition, muscle strength and physical performance, with the authors reporting on duration as a factor in the observed effects.

Systematic review, 2026

The analysis compared combinations of protein source and exercise modality to describe which pairings carried the larger reported effects on the outcomes examined.

Across 38 trials, magnesium lowered the top blood pressure number by about 2.8 mmHg and the bottom number by about 2.1 mmHg, with bigger drops in people who started with low blood magnesium.

Meta-analysis, 2022

Blueberry supplementation improved some components of metabolic health in pooled trials, with the effect differing by marker.

Systematic review, 2025

Pooling human trials of apple cider vinegar, the review found small reductions in body weight and waist measures in adults with raised blood sugar or excess body weight, and described the evidence base as limited.

Systematic review, 2025

Across the trials pooled, plant proteins were used for recovery from resistance-exercise-induced muscle damage in healthy young adults, with the authors summarising the range of reported effects rather than a single figure.

In adults with elevated blood pressure carrying the MTHFR 677TT genotype, riboflavin 1.6 mg per day lowered systolic blood pressure by about 5.6 mmHg versus placebo over 16 weeks.

Meta-analysis, 2023

Pooling human trials, Lycium barbarum supplementation was associated with modest reductions in total cholesterol and triglycerides in adults, with variation across studies.

Cohort study, 2026

Reports an association between dietary thiamin, riboflavin and niacin intake and elevated blood pressure and pulse pressure. An association in intake data, not a demonstration of cause.

Meta-analysis, 2023

Pooling randomised trials, amla supplementation was associated with lower total and LDL cholesterol, lower fasting blood sugar and lower C-reactive protein than control, all of which are laboratory markers rather than health outcomes.

Randomised trial, 2011

In 22 healthy volunteers, four weeks of tulsi leaf extract raised several immune system markers compared with placebo, laboratory markers rather than measured health outcomes.

Randomised trial, 2024

A randomised controlled trial characterised the sugar composition of Thai desserts and measured shifts in gut microbiome composition in healthy volunteers consuming them.

Randomised trial, 2026

Animal- and plant-derived protein supplementation shifted gut microbial community structure and predicted metabolic potential. These are microbiome measurements, not clinical outcomes.

Randomised trial, 2023

A trial of a goji berry mouthwash reported changes in plaque and gum inflammation scores versus a comparator rinse, clinical measures of gum tissue rather than a systemic outcome.

Randomised trial, 2016

In healthy adults, a single serving of Psidium guajava fruit juice was followed by lower platelet aggregation in blood samples taken after intake than at baseline, a laboratory marker rather than a clinical outcome.

Cohort study, 2010

In volunteers, a supplement containing goji berry was followed by more circulating stem and progenitor cells, an uncontrolled observation that cannot show the berry caused it.

Systematic review, 2026

The review found that reported responsiveness to riboflavin across inherited disorders of metabolism is uneven and rests largely on small series, so the strength of evidence varies by the specific condition.

Meta-analysis, 2025

Across trials, blueberries produced small improvements in memory and executive function measures.

Randomised trial, 2022

In 100 adults under stress, 125 mg of a standardised Ocimum sanctum extract twice daily for 8 weeks lowered perceived stress scores (p = 0.003) and sleep-difficulty scores (p = 0.025) and left hair cortisol lower at week 8 (p = 0.025) compared with placebo.

Randomised trial, 2015

Thirty days of 300 mg a day of ethanolic holy basil leaf extract shortened reaction times and lowered error rates on memory and attention tasks compared with placebo in healthy adults, with no change detected in heart rate or skin conductance.

Randomised trial, 2020

A controlled trial tested sugar cane flour, a fiber-containing whole cane fraction rather than refined sugar, against self-reported upper digestive comfort.

Randomised trial, 2019

A flavonoid-rich mixed berry drink was tested against a matched control on cognitive test performance across a six hour window in healthy young adults. Goji is named only as one component of the wider berry literature, so this is not evidence for goji on its own.

Systematic review, 2026

A systematic review of dietary flavonoids and mood that includes berry anthocyanin trials. The authors report mixed results across a heterogeneous set of studies.

The review documents long-standing traditional use of Psidium guajava leaf preparations for gastrointestinal complaints and describes tannin and flavonoid constituents that reduce intestinal motility and secretion in laboratory models.

Systematic review, 2025

The review compared plant against animal protein on muscle mass, strength and physical performance and did not detect a clear separation between the sources in the trials available, which is a failure to detect a difference within the limits of that evidence base rather than a demonstration that the sources are equivalent.

Systematic review, 2025

An umbrella review of water-soluble vitamins, biotin among them, found only small and inconsistent changes in blood sugar and insulin sensitivity measures in adults with raised glucose.

Randomised trial, 2025

A plant-based protein blend and an animal-based comparator produced similar muscle adaptation results. No difference was detected between them, which is not the same as showing they are identical.

Meta-analysis, 2017

Across randomised trials, blueberry supplementation did not produce a detectable change in systolic or diastolic blood pressure.

Randomised trial, 2019

Thiamin supplementation did not improve left ventricular ejection fraction in the participants studied. This is a failure to detect a difference in an imaging marker, not evidence that no difference exists.

Randomised trial, 2021

Adding baobab fruit pulp to the diet did not produce a detectable improvement in haemoglobin levels in the group studied.

Systematic review, 2023

Across 18 studies, pyridoxine on its own and in combinations improved nausea scores in pregnancy on both the Rhode and PUQE scales, a use with a long clinical track record.
