Modulation of Intestinal-Bone Crosstalk by a Standardised Nutraceutical Combination: An In Vitro Mechanistic Study

Area of Science:

• Nutraceutical science
• Cell biology
• Biochemistry

Background:

• Natural nutraceuticals may impact metabolic and bone health pathways.
• Investigating gut-bone axis modulation is crucial for integrated health.
• Redox-inflammatory signaling plays a role in metabolic and bone disorders.

Purpose of the Study:

• Evaluate a botanical-vitamin formulation's effects on intestinal barrier integrity and bone cell activity.
• Assess the formulation's impact on gut-bone crosstalk and redox-inflammatory signaling.
• Determine potential synergistic interactions among formulation components.

Main Methods:

• Utilized in vitro models including intestinal, osteoblastic, and osteoclastic cell lines.
• Assessed formulation effects on cytocompatibility, barrier function, and cellular uptake.
• Employed biochemical, molecular, and enzymatic assays for osteogenesis/osteoclastogenesis markers and oxidative stress.

Main Results:

• The formulation enhanced intestinal barrier integrity and bioavailability without cytotoxicity.
• It promoted osteoblastic differentiation and reduced oxidative stress.
• Osteoclast differentiation and resorptive activity were inhibited, with synergistic component interactions observed.

Conclusions:

• The findings support a multi-target nutraceutical strategy for concurrent gut barrier and bone remodeling influence.
• Mechanistic evidence for modulating the gut-bone axis in vitro was provided.
• Further research in advanced models and clinical trials is warranted.
