How Gut Health Shapes Protein Absorption, Bone Strength & Metabolic Balance

November 7, 2025

Your gut is far more than a digestive organ — it’s the control centre for your immune system, metabolic balance, and even bone strength.

Recent studies have shown that maintaining a diverse and balanced gut microbiome can enhance nutrient absorption, reduce inflammation, and support healthy ageing.

Let’s look at three powerful new studies showing how probiotics and prebiotics — especially in combination — can improve whole-body health.

1. Probiotics Improve Protein Absorption and Utilisation

A review published in Probiotics and Antimicrobial Proteins (read the study here) found that the probiotic strain Bacillus coagulans GBI-30, 6086 can enhance how your body digests and uses protein.

This spore-forming probiotic survives stomach acid and becomes active in the small intestine, where it:

Aids digestion of proteins and carbohydrates
Improves nutrient absorption efficiency
Supports the intestinal microbiota for optimal gut balance

For athletes, active adults, or anyone using protein supplements, this means greater benefits from every serve — helping muscles recover, metabolism thrive, and energy remain steady.

2. The Gut–Immune–Bone Connection

A groundbreaking 2025 study in Gut Microbes (read the study here) revealed that Bacillus coagulans may also help protect against bone loss in post-menopausal women by restoring gut balance and calming inflammation — a process known as the Gut–Immune–Bone Axis.

Researchers found that probiotic supplementation:

Improved bone mineral density and strength
Enhanced gut microbiome composition by increasing SCFA-producing bacteria
Reduced inflammation linked to bone breakdown

This study highlights how a healthy gut can reduce inflammation and support bone metabolism — especially under hormonal changes.

3. Synbiotics Support Weight Management and Metabolic Health

A 2023 human clinical trial published in Nutrients (read the study here) explored how combining probiotics and prebiotics — together known as a synbiotic — could improve weight and metabolic health in adults with abdominal overweight.

In this 12-week, double-blind, randomised, placebo-controlled trial, 180 participants were divided into three groups:

Placebo,
Probiotic, and
Synbiotic.

The findings were impressive:

Participants in the probiotic group lost significantly more body fat mass compared to placebo.
Both the probiotic and synbiotic groups showed reductions in BMI, waist circumference, and visceral fat — key markers of metabolic improvement.
Those taking the synbiotic experienced additional benefits, including better liver health and improved bowel regularity.

Researchers attributed these effects to the anti-inflammatory and gut-regulating properties of the probiotic strains and the prebiotic fibre’s ability to nourish beneficial bacteria. Together, they helped reduce the low-grade inflammation that underpins metabolic syndrome and poor fat metabolism.

In short, the study confirmed that synbiotics outperform probiotics alone when it comes to improving body composition and metabolic balance — strengthening the case for combining both in a single daily formula.

If your goal is to support healthy digestion, reduce inflammation, and promote metabolic wellness, Gut Health Plus delivers exactly that synergy. It combines the clinically recognised probiotic Bacillus coagulans with Partially Hydrolysed Guar Gum (PHGG) — a gentle prebiotic fibre that supports balanced gut microbiota and sustainable metabolic health.

You can also explore Partially Hydrolysed Guar Gum (PHGG) as a standalone prebiotic to further enhance digestive comfort and microbiome diversity.

The Power of Synbiotics: Probiotics + Prebiotics

The above studies underline one major theme — probiotics and prebiotics work best together.

This is where synbiotics come in.

A synbiotic combines beneficial bacteria (probiotics) with the nutrients that feed them (prebiotics).

Together, they create a thriving environment for gut microbes to flourish and produce beneficial short-chain fatty acids (SCFAs), which support:

Digestive harmony
Immune regulation
Hormonal and metabolic health
Anti-inflammatory pathways that protect organs, muscles, and bones

Your Daily Gut Health Solution

Gut Health Plus formula combines:

Partially Hydrolysed Guar Gum (PHGG) – a gentle, clinically backed prebiotic fibre that promotes the growth of beneficial bacteria and supports bowel regularity.
Bacillus coagulans (Lactospore®) – a resilient probiotic strain shown to improve protein absorption, gut balance, and inflammation regulation.

Together, they deliver a complete synbiotic solution that supports gut microbiome health, nutrient absorption, and overall vitality.For those focused specifically on fibre intake, you can also explore Partially Hydrolysed Guar Gum (PHGG) - a standalone prebiotic fibre ideal for sensitive digestive systems.

The Takeaway

From better protein absorption to stronger bones and metabolic balance, the research is clear — your gut is central to your health.By supporting it with a high-quality synbiotic supplement like Gut Health Plus, you nourish the beneficial bacteria that drive energy, digestion, and immune function from the inside out.
