Tributyrin (NewBiome): Why It's in Your HOP Box
Feeding Your Gut the Fuel It Needs to Protect You
Your gut lining is a single layer of cells that separates the inside of your body from the outside world. When this barrier breaks down (a condition sometimes called "leaky gut"), bacterial toxins enter your bloodstream and trigger systemic inflammation that accelerates aging throughout your body.
Butyrate is a short-chain fatty acid that is the primary fuel source for the cells lining your colon. Your gut bacteria produce butyrate when they ferment dietary fiber, but production often declines with age, stress, antibiotic use, and low-fiber diets.
Tributyrin is a prodrug of butyrate that delivers it directly and more efficiently than butyrate supplements alone. HOP Box uses NewBiome, a patented tributyrin form, as part of the Equalizer blend to support gut barrier integrity, reduce systemic inflammation, and optimize nutrient absorption.
What the Research Shows
Gut barrier integrity
A compromised gut barrier is increasingly recognized as a driver of chronic inflammation, autoimmune conditions, and metabolic disease.
Key study: Butyrate supplementation has been shown in human trials to strengthen tight junctions between intestinal epithelial cells, reduce intestinal permeability, and decrease markers of endotoxemia (bacterial toxins entering the bloodstream). These effects directly support gut barrier function and reduce systemic inflammatory load.

Inflammatory bowel conditions
Butyrate's anti-inflammatory effects in the gut are well documented in human clinical trials.
Key study: A randomized controlled trial of patients with ulcerative colitis found that butyrate enemas (combined with oral mesalazine) significantly improved clinical and endoscopic outcomes compared to mesalazine alone, demonstrating butyrate's direct anti-inflammatory effects on the gut mucosa.

Metabolic health and insulin sensitivity
Gut health and metabolic health are deeply connected. Butyrate has demonstrated effects on blood sugar regulation and insulin sensitivity.
Key study: A randomized, double-blind, placebo-controlled crossover trial found that oral butyrate supplementation (4 g/day for 4 weeks) improved insulin sensitivity in lean men, as measured by hyperinsulinemic-euglycemic clamp. These findings suggest butyrate may help protect against metabolic dysfunction.

GI pain and bloating reduction (especially in women)
A large clinical trial showed particular benefits for women, especially postmenopausal women.
Key study: A 6-week, randomized, double-blind, placebo-controlled trial of 596 participants found that ButyraGen (tributyrin, 200 mg/day) significantly reduced belly pain compared to placebo. Women experienced a 20.3% greater reduction in belly pain and 14.9% decrease in gas and bloating vs. placebo. Postmenopausal women showed the greatest benefit: a 26.4% greater improvement in belly pain scores.

Tolerability and anti-inflammatory markers
Key study: A pilot study of 29 healthy adults taking ButyraGen tributyrin (200 or 400 mg daily for 21 days) showed excellent tolerability (less than 10% reported GI discomfort) and trends toward decreased high-sensitivity C-reactive protein, suggesting systemic anti-inflammatory benefits even at low doses.

Why It's in HOP Box
Dr. Amy Killen included tributyrin in HOP Box because gut health is foundational to every aspect of longevity. You cannot absorb the other 18 ingredients in HOP Box if your gut barrier is compromised. You cannot manage inflammation if bacterial toxins are constantly leaking into your bloodstream. And you cannot optimize your metabolism if your gut microbiome is not being properly fueled.
The NewBiome form of tributyrin was chosen specifically for its superior delivery: it reaches the colon (where butyrate is needed most) without the odor and absorption problems of standard butyrate supplements.
In the Equalizer blend, tributyrin works alongside dihydroberberine (GlucoVantage) to support both gut health and metabolic balance.
The HOP Box Difference
- NewBiome tributyrin for targeted colon delivery without the smell
- Supports gut barrier integrity to reduce systemic inflammation
- Part of the Equalizer blend with dihydroberberine for metabolic and gut synergy
- Doctor-formulated by Amy Killen, MD, a longevity medicine specialist
- Convenient daily packs for consistent gut support
