Probiotic For Performance - Used In Clinical Trials

PRP's New Intensive Training Probiotic Complex is a Probiotic designed to increase performance and aid digestion during intense exercise. It contains the unique Lab4 group of probiotic organisms, along with a few other specially selected ingredients; L-Glutamine, N-Acetyl Glucosamine and ElavATP(™)

The Lab4 strain of probiotic found in Intensive Training Probiotic Complex has been used in 4 clinical studies in relation to performance, particularly endurance sports.




Formulated To Enhance Performance

Research-Backed Bacteria

The four friendly and beneficial species of bacteria used in LAB4 are the most comprehensively studied group of friendly bacteria of any product in the UK. The Lab4 consortium of probiotic bacteria has been incorporated into many popular brands of probiotic and has benefited thousands of people for over 15 years.

Proven In Athletes

As well as clinical trials, LAB4 has increasingly been shown to benefit athletes, particularly endurance athletes (see below).

Added Ingredients To Make The Difference

Glutamine is one of the most abundant amino acids within the body and is the major fuel source of the small intestine. ElavATP is a mineral sourced from ancient peat bogs which work with our natural energy-producing mechanisms to stimulate the production of ATP, the energy currency of the body. It was also voted Sports Nutrition Ingredient of the year by NutraIngredients USA.


Athletic Studies

The Lab4 strain of probiotic found in Intensive Training Probiotic Complex has been used in 4 clinical studies in relation to performance, particularly endurance sports.

These studies are:


Marathon Des Sables Study - 12% Quicker Overall Race Time

Runners competing in the Marathon des Sables (often called the toughest race on the planet) had an overall race time that was 12% quicker after supplementing with Lab4 probiotics compared to placebo (Marshall et al.m 2017)

The Hertfordshire Study - 10% Quicker Overall Race Time

In ironman triathletes, participants supplemented with probiotics or placebo for 12 weeks. Those taking probiotics had a 10% quicker overall race time than those on the placebo. Those taking probiotics also suffered from fewer and less severe gut symptoms (e.g. bloating, urge to defecate, nausea, etc.) during training compared to the placebo group. (Roberts et al., 2016)

The Hertfordshire Study - Participants Ran For ~15% Longer

When runners supplemented with Lab4 probiotics for 4 weeks and asked to run to exhaustion in the heat, they were able to run for ~15% longer compared to when they had taken the placebo (Shing et al., 2014)

The Liverpool Endurance Study - Reduced GI Symptoms During Marathon Race

Four weeks of probiotic supplementation reduces GI symptoms during a marathon race.
