The Microbes4U® study is the first randomised double-blind placebo-controlled pilot study to evaluate the effects of pasteurised Akkermansia muciniphilaadministered in humans.
To verify the safety of the bacteria.
To determine the safety, tolerance and metabolic parameters (i.e. insulin resistance, circulating lipids, visceral adiposity, body mass) after three months of daily administration in overweight or obese subjects suffering from metabolic syndrome and insulin resistance.
To look at the gut barrier function (i.e. plasma lipopolysacharrides) and gut microbiota composition.
What were participants asked to do?
a placebo (identical to the active product in form, size, taste and colour)
ten billion Akkermansia muciniphila bacteria in living form, or
ten billion Akkermansia muciniphila bacteria in pasteurised form.
What was assessed?
What were the results?
Results showed that taking 10 billion bacteria orally every day, whether live or pasteurised, was safe and well tolerated with excellent participant compliance. None of the participants reported any major side effects.
Additionally, for the first time, the results of the Microbes4U® study showed that Akkermansia muciniphila, when pasteurised, has the ability to slow down the progress of metabolic disorders.
Compared to the placebo, taking pasteurised Akkermansia muciniphila daily:
Results of the Microbes4U® study
The Microbes4U® study highlights that taking pasteurised Akkermansia muciniphila every day for a period of three months is well tolerated and able to improve the cardiometabolic risk profile in overweight/ obese people with insulin resistance.
