Effect of two different fibre supplements on blood pressure, arterial stiffness and C-reactive protein in adults with overweight and obesity consumed over 12 months, in a randomised controlled trial
Bibliographic record
Abstract
Adequate fibre consumption is associated with reduced risk of metabolic syndrome and cardiovascular disease. This study examined the effects of supplementation with PolyGlycopleX® (PGX®), a complex of 3 polysaccharides (fibre product), on blood pressure, arterial stiffness and C-reactive protein in overweight and obese participants. In this double-blind 12-month trial, participants were randomised into three groups: control (CTR; rice flour); PGX or a proprietary psyllium product (PSY). Participants added the 5 g supplements to their habitual diet and lifestyle, three times daily before meals. Between-groups analysis shows that systolic blood pressure was significantly lower in the PGX group at 3 months compared to CTR; stiffness index in the PGX group was significantly lower at 3 months compared to CTR. Within-group analysis shows systolic and diastolic blood pressure, as well as arterial stiffness, to be significantly lower in the PGX group at 3 months compared to baseline. While fibre supplementation may be an effective strategy to reduce chronic disease risk factors without the need for other dietary modifications, the present study suggests that more clinical trials with PGX are needed to clarify whether supplementing the with this product will reduce inflammation and improve vascular health in overweight and obese individuals.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
