What are the benefits of a ‘Crapsule’ (FMT)?
06 May 2025

In this article, we’ll explain to you the potential benefits of a "Crapsule" (Faecal Microbiota Transplant or FMT). We’ll explain what a Crapsule is, how it’s formulated and the conditions it’s designed to treat. You’ll also learn how FMT works including how the faecal matter transplant is prepared to how it is used. We will also discuss the challenges that come with adopting FMT as a mainstream treatment.
Key Takeaways
Here are the 5 biggest takeaways from this article about the benefits of an FMT “crapsule”:
A "crapsule" is an informal term for an oral capsule containing faecal matter used in a Faecal Microbiota Transplant (FMT).
FMT is primarily used to treat recurrent infections, however it may also help with conditions linked to gut microbiome imbalances. Examples include Inflammatory Bowel Disease (IBD), Irritable Bowel Syndrome (IBS), metabolic disorders, autoimmune diseases and mental health conditions.
FMT works by rebalancing the gut microbiome, which can be disrupted by harmful bacteria.
The preparation of FMT involves screening donors for health and infectious diseases, collecting and freeze-drying their stool, and then processing it into acid-resistant capsules.
Faecal transplants face challenges, including overcoming the "yuk" factor associated with using faecal matter, which can deter both patients and healthcare providers.
What is a crapsule?
A "crapsule" is an informal term for a capsule that contains faecal matter used in a Faecal Microbiota Transplant (FMT). The purpose of a crapsule is to introduce healthy gut bacteria from a donor's faeces into the digestive system of a patient. This can help restore the balance of bacteria in the gut, which is crucial for digestion and overall health. The capsule is usually taken orally, allowing the faecal matter to reach the intestines where it can help treat numerous conditions.
What health conditions could a faecal transplant help to treat?
Faecal transplants are primarily used to treat recurrent infections that cause severe diarrhoea and inflammation of the colon. Infections of this nature often occur after standard antibiotic treatments.
Recently, research is exploring the potential of FMT for treating other health conditions linked to gut microbiome imbalances, including:
Inflammatory Bowel Disease (IBD) including Crohn's disease and ulcerative colitis
FMT may help reduce inflammation and symptoms of IBD [1].
Irritable Bowel Syndrome (IBS)
FMT could potentially improve symptoms like bloating, pain, and irregular bowel movements associated with IBS [2].
Metabolic Disorders
Obesity and type 2 diabetes may be helped by potentially influencing gut bacteria linked to metabolism and insulin resistance [3].
Autoimmune Diseases
Early studies suggest FMT might play a role in modulating immune responses in conditions like multiple sclerosis [4].
Mental Health Conditions:
There's emerging research into FMT's effects on depression, anxiety and autism, as the gut-brain axis becomes better understood [5].
While FMT has shown to be a promising option for treatment in these areas, it is still largely considered experimental for conditions beyond C. difficile infections.
How does a faecal microbiota transplant (FMT) work?
A Faecal Microbiota Transplant (FMT) works by restoring the natural balance of bacteria in the gut, which is crucial for maintaining overall health. Harmful bacteria disrupt this balance, leading to severe digestive issues. By introducing healthy bacteria from a donor's faeces into the gut, FMT can help to re-establish this balance of bacteria. The exact mechanisms of FMT are complex [6].
The gut is home to trillions of organisms that will affect different conditions, symptoms and bodily functions. A simple way to picture FMT is like turning on and off a computer. FMT effectively “reboots" the gut's immune system, allowing it to function correctly again.
How is a faecal microbiota transplant prepared?
A faecal microbiota transplant (FMT) is carefully prepared to ensure it is both effective and safe for the patient. The process begins with careful screening to find suitable donors. This involves a comprehensive health questionnaire as well as collection of blood and stool samples. Once suitable donors are found, stool samples are collected [7].
These samples are freeze-dried to preserve the beneficial bacteria and other important components [8]. Next, the freeze-dried stool is processed and filtered into acid-resistant capsules. These capsules are designed to withstand the harsh environment of the stomach, allowing them to safely pass through the digestive system.
How do you take a crapsule?
Taking a crapsule is simple and non-invasive. Your doctor may give you specific instructions, such as fasting before the procedure to optimise the treatment's effectiveness, however, this is not always the case. The capsules are usually taken orally with water, usually in a single session, though the exact dosage and timing will be determined by your healthcare provider. After taking the capsules, you may need to wait before eating or drinking and your doctor will usually monitor you for any side effects. You may also need to attend follow-up appointments to assess the treatment's success and ensure everything is progressing.
What are the challenges for faecal transplants to become a mainstream medicine?
Despite their potential, faecal transplants face several challenges before they can become mainstream medicine. One major hurdle is overcoming the "yuk" factor associated with using faecal matter as a treatment, which can put off both patients and healthcare providers. The Guardian states that less than a third of patients approached for oral capsule trials were willing to participate. As well as this, more extensive and successful clinical trials are needed to demonstrate the efficacy and safety of faecal transplants for various conditions [9].
Final Thoughts from Yusra
While the concept of a “crapsule” may sound unorthodox, Faecal Microbiota Transplants (FMT) offer a promising approach to treating a range of health conditions linked to an imbalanced gut microbiome. From fighting infections to supporting ongoing research into digestive, metabolic, autoimmune and mental health conditions, FMT is gaining attention as a potential alternative to conventional treatments.
