Body Composition

Dibifree, a dietary phytomix, improves glycemic control and adiposity via modulation of the gut-pancreas-adipose-immune axis in type 2 diabetes.

TL;DR

Dibifree, a dietary phytomix add-on therapy, significantly reduced HbA1c, fasting and postprandial glucose, and body fat percentage in T2D patients, with mechanistic evidence supporting multi-target actions across the gut-pancreas-adipose-immune axis.

Key Findings

Dibifree as add-on therapy significantly reduced HbA1c compared with placebo in a randomized controlled trial.

  • Study design: 7-month randomized, double-blind, placebo-controlled crossover trial with 40 adults with T2D.
  • Dibifree was administered at 15 g/day as add-on therapy for two 3-month sessions separated by a 1-month wash-out.
  • HbA1c was a primary endpoint and was significantly reduced compared to placebo.
  • Effects were sustained after wash-out and upon re-challenge with Dibifree.

Dibifree significantly reduced fasting and postprandial glucose compared with placebo.

  • Fasting glucose and postprandial glucose were both primary endpoints.
  • Reductions were statistically significant compared to the placebo arm.
  • Effects persisted after the wash-out period and were reproduced upon re-challenge.
  • The crossover design allowed placebo recipients to switch to Dibifree in the second session, providing additional within-subject comparisons.

Dibifree reduced body fat percentage in T2D patients.

  • Body fat percentage decreased in Dibifree-treated subjects.
  • Body weight was listed as a primary endpoint alongside glycemic measures.
  • Reduction in adiposity was consistent with in vitro findings of suppressed adipogenesis.
  • This was observed in the context of an add-on therapy to existing diabetes treatment.

Transcriptomic profiling of Dibifree-treated cell lines revealed reversal of diabetic gene signatures and enrichment of multiple metabolic pathways.

  • Pathways enriched included cAMP/GLP-1, insulin secretion, AGE-RAGE, and IL-10 pathways.
  • Analysis involved transcriptomic profiling of treated cell lines followed by pathway enrichment analyses.
  • Results indicated a reversal of diabetic gene expression signatures.
  • These findings provided a mechanistic basis for the multi-target effects of Dibifree.

Dibifree demonstrated enhanced GLP-1 secretion and inhibition of DPP-4 and α-glucosidase in functional assays.

  • Incretin activity was assessed via in vitro assays showing enhanced GLP-1 secretion.
  • DPP-4 inhibition was confirmed, which would prolong endogenous GLP-1 activity.
  • α-glucosidase inhibition was demonstrated, consistent with delayed carbohydrate absorption.
  • Improved glucose tolerance was also observed in T2D mice in vivo.

Dibifree reduced advanced glycation end-product (AGE) formation in functional assays.

  • Inhibition of AGE formation was demonstrated in vitro.
  • This activity corresponded to enrichment of the AGE-RAGE pathway in transcriptomic analyses.
  • Reduction of AGE formation is relevant to prevention of diabetic complications.
  • This was one of several multi-target mechanisms identified for Dibifree.

Dibifree suppressed adipogenesis and promoted M2 macrophage polarization in functional assays.

  • In vitro assays demonstrated suppression of adipogenesis, consistent with the observed reduction in body fat percentage in clinical participants.
  • Promotion of M2 macrophage polarization was demonstrated, indicating an anti-inflammatory immune modulation effect.
  • These findings corresponded to IL-10 pathway enrichment in transcriptomic analyses.
  • These mechanisms were described as relevant to metabolic and immune regulation in T2D.

Dibifree was formulated as a dietary phytomix using food-derived anti-diabetic bioactivities and administered at 15 g/day.

  • Dibifree was developed by integrating dietary and therapeutic strategies for T2D management.
  • The dose was 15 g/day administered as add-on therapy to existing treatments.
  • The product is described as a functional food intervention.
  • Mechanistic studies used integrated bioinformatics and functional assays to elucidate the basis of its effects.
