BPC-157 and gut lining claims: what TikTok gets wrong

What did @gracie_norton actually say?

The creator describes a history of bloating, inflammation, and irregular digestion she attributed to "leaky gut," a condition her doctor apparently diagnosed. She credits four main interventions: a supplement called albudamine powder, MCT oil, probiotics, digestive enzymes, and daily bone broth for its glycine content. Her framing is largely anecdotal, and she does close with a disclaimer to consult your doctor. That is worth noting. But the video has half a million views, and the claims in between that opening and closing disclaimer deserve a closer look.

Her description of leaky gut, specifically "undigested food particles leaking through my intestinal wall into my bloodstream," tracks with the lay understanding of intestinal permeability. The phrase is imprecise but not wildly wrong. What matters more is whether the supplements she recommends actually do what she says they do.

Does the science back this up?

Partially. The glycine-bone broth connection is probably the strongest claim here. The probiotic claim is well-supported but vague. MCT oil has real but modest gastrointestinal effects. Albudamine powder is the problem.

On glycine: animal and in vitro studies do show glycine supports gut barrier function. A 2017 study by Martínez-Augustin et al. in Current Opinion in Clinical Nutrition and Metabolic Care noted glycine plays a role in intestinal epithelial integrity. Human data is thinner but not nonexistent. The bone broth delivery mechanism is fine, though the glycine concentration in broth varies widely and is hard to standardize.

On probiotics: the evidence base for probiotics and gut barrier function is genuinely broad. A 2021 meta-analysis by Zhong et al. in Frontiers in Nutrition found multi-strain probiotic supplementation significantly reduced intestinal permeability markers. Credit where it is due.

On albudamine powder: there is no well-known supplement by this name with meaningful clinical data behind it. This is either a brand name for something else or an obscure compound. Calling it "the MVP" to an audience of 500,000 people without any supporting evidence is a real problem.

What did they get wrong (or right)?

The creator got a few things right. The bone broth and glycine connection is directionally accurate, even if it is not as simple as she makes it sound. Probiotics having a role in gut flora balance is not controversial. Digestive enzymes have some evidence behind them for people with specific enzyme deficiencies, though the general use case is less clear.

What she got wrong, or at minimum oversimplified: "leaky gut" as a discrete clinical diagnosis remains contested. Increased intestinal permeability is a real, measurable phenomenon, but many practitioners use "leaky gut" as a catch-all that bundles together poorly defined symptom clusters. A 2019 review by Camilleri in Clinical Gastroenterology and Hepatology noted that while intestinal permeability is measurable and clinically relevant, its role as a primary driver of systemic symptoms in otherwise healthy people is not firmly established.

The biggest issue is the albudamine recommendation. Without transparency about what this actually is or any citation of evidence, recommending it as the top supplement in a video seen by hundreds of thousands of people is irresponsible.

What should you actually know?

Intestinal permeability is a real phenomenon studied in conditions like Crohn's disease, celiac disease, and IBS. But the leap from "I felt bloated and found out I had leaky gut" to a specific supplement protocol is a big one, and it skips several steps that matter, including proper diagnostic testing and working with a gastroenterologist rather than self-diagnosing from symptom checklists.

If you are genuinely dealing with gut symptoms, the interventions with the best evidence are not exotic. Dietary fiber, established probiotic strains like Lactobacillus rhamnosus GG, stress reduction, and adequate sleep all have more clinical backing than most boutique supplement stacks. Glycine supplementation is showing early promise in research, but it is early. MCT oil can help some people with fat digestion but can worsen symptoms in others, which the creator actually acknowledged honestly.

Before spending money on any supplement protocol for gut symptoms, ask your doctor for a referral to a gastroenterologist and get a proper workup. A diagnosis of "leaky gut" from a wellness-oriented provider without objective testing is worth scrutinizing.
