1. What is a delayed release capsule?

The vegetable based capsule which carries the ingredients is designed to resist the acid in the stomach allowing the healthy bacteria to pass into the remaining gut where they are most needed.

2. What other lifestyle and dietary factors can also effect gut health?

Taking this probiotic is not just the only thing which helps improve the profile of healthy to unhealthy bacteria in the gut. Try to stop smoking, exercise more, reduce processed sugar intake, eat something with live probiotic bacteria every day such as kefir, sauerkraut and foods which help feed these bacteria such as fruit, fibre, vegetables, mushrooms and beans – read more on practical tips on: Keep-healthy.com/gut-health

3. What is the evidence that gut health is impaired after covid?

Depleted healthy strains of commensal bacteria such as Lactobacillus have been reported in the majority of patients with Covid expressing Gastrointestinal (GI) symptoms and especially those with persistent ongoing problems, coined long or chronic Covid:

4. What is the evidence linking the lactobacillus helps with covid?

The Kings App study, which recorded habits of over 450,000 people over the last 2 years established a link between people who took probiotics and a lower risk of Covid:

Sudre C, et al. (2021) Symptom clusters in COVID-19: A potential clinical prediction tool from the COVIDSymptom Study Sci Adv 7: eabd4177.

The Bedford and Cambridge study reported a significant approximately three fold improvement in symptoms in participants with acute and long term covid:

Two other robust studies from across the world have also shown significant benefits for similar blend sof lactobacillus. One protecting family contacts from catching covid and another reducing during of symptoms:

5. Did yourgutplus+ plus help everyone on the study?

In the formal trial, published in January 2020, the rate and degree of improvement was approximately three times greater than expected without it. Not everybody responded and a minority with sever long covid did not improve in the time frame of the study but most continued to take both supplements going forward. It seemed to benefit most participants but men, older people, those with a history of indigestion and those who did not exercise very much seemed to get a particular good benefit.

6. Is it safe to take this probiotic in the long term?

This lactobacillus blend was specifically chosen with long term safety in mind. Patients in the study did not report any problems taking it for several months. We cannot foresee and issues in taking it continually at these doses (2 a day). Although it’s normal to have some increased gas or bloating for a few days after starting, this should settle and bowel symptoms normally then improve. In the very unlikely event that a person experiences excess gas or bloating after taking yourgutplus+ for several months then it would be sensible to have a two week break before continuing.

8. Is there evidence that probiotics helps other conditions?

Excess chronic inflammation of the gut wall caused by too many pro-inflammatory (bad ) bacteria over time will thin and damage the integrity of the gut wall. This leads, not only to an increase in conditions of the gut such as irritable bowel, ulcers, cancer and food intolerances, it leads to an increased risk of multiple chronic conditions throughout the body ranging from fatigue, poor exercise performance, arthritis, high cholesterol, low mood and dementia – I comprehensive summary of the links between poor gut health and disease can be found on: Keep-healthy.com/gut-health

9. Does Yourgutplus+ need to store in cold ? Does high temperature during transportation will affect. 

There are several reasons why Yourgutplus+ does not need to be stored in the cold and can sustain even quite high temperature changes during transportation:

The lactobacillus probiotic strains in yourgutplus+ are more resistant loss of viability than other species.

The encapsulation of the probiotics ensures a stable PH, protects them from light, oxidation and humidity. It’s humidity which is most important so after opening the pack it would be good to store in a cold dry place if they are not going to be consumed within a month:

While they are stored and transported the Yourgutplus probiotics are supplied in a dormant (non-growing) state, due to the drying process. This process removes most of the water from around and inside the cells, leaving the microbes in a dormant state. A water activity close to zero impairs growth ensuring that no metabolic activity will take place during the shelf life of the product. When they are swallowed the water and nutrients in the gut move them back into a growth phase.

After drying, studies have shown that inactivation of Lactobacillus was initially observed at temperature of 61-65 °C. By contrast, deactivation occurred at around 54 °C for non-dehydrated strains. It is very unlikely that the probiotics will be exposed to temperatures above 40 °C let alone 60°C

There is evidence that the Inulin also offers further protection from heat.

It is well known that some of the probiotics do not recover from the packaging process which is why large numbers are added to each capsule – the amount left is still very significant. What is also important is there data to show that even damaged probiotics which are not able to pass into the growth phase still offer health benefits. For example, in a randomized, double-blind, placebo-controlled trial in 443 individuals with IBS involving orally administered, heat-inactivated probiotics substantially alleviated symptoms associated with IBS, such as abdominal pain or discomfort, abdominal bloating and abnormal bowel habits 1.
