Why customers take it

"..much less bloating and digestive issues"

"Feeling a positive difference after only a week, much less bloating and digestive issues, and more "regular". Very happy to find a good vegan product. Customer service great too." Hanna

"IBS Control"

"I have suffered from IBS for years and I have found that using this product keeps it well under control" - Sharon H

Antibiotics Support

Antibiotics can disrupt the balance of bacteria in the gut, leading to issues like diarrhoea. Probiotics can help restore the natural balance and reduce the risk of antibiotic-associated problems.

Mental Health

Probiotics can support mood and mental well-being. Emerging research suggests a connection between the gut and the brain, known as the gut-brain axis, which can be harmed by a bad microbiome in the colon. 

Immune Support

Did you know 7% to 90% of your immune system resides in the gut? Probiotics support immune function by promoting the production of antibodies and enhancing the activity of immune cells.

Better Digestion & Nutrition

Our probiotic helps maintain a healthy digestive system by helping to break down food, prevent the overgrowth of harmful bacteria, and reduce issues like bloating, gas, and indigestion.

Vaginal Health

For women, probiotics are vital for maintaining a balanced vaginal microbiome, reducing the risk of infections and promoting a healthy, natural smell. This in turn helps prevent cystitis and bladder infections.

Weight Management

We included bacteria that are proven to help people who are dieting to lose weight and keep it off: Lactobacillus gasseri,  Lactobacillus rhamnosus, Lactobacillus plantarum and Bifidobacterium breve.

Why it's so good

Each culture strain in our probiotic is chosen for its unique health benefits. Nutritionists recommend that the best way to maximise good gut health is through a balance of bacteria that is diverse as well as beneficial.

This high-strength probiotic supplement introduces significant amounts of 17 of the most researched and sought-after probiotic culture strains available, each hand-picked for their effectiveness, robustness and their ability to work together. 


Improving the health of your gut microbiome can have an incredible range of health benefits.  

  • Probiotics are popular for reducing symptoms from digestive complaints such as IBS and colitis and for restoring balance after antibiotics. They can also reduce symptoms of lactose intolerance and problems with diarrhoea after eating fruit.
  • Research indicates probiotics help to boost immunity and fight infections.
  • Probiotics improve nutrient absorption.
  • They fight inflammation, and help suppress allergies.
  • Probiotic bacteria play a major role in mental health and have been found able to improve mood and behaviour. Some research suggests that an unhealthy gut microbiome is associated with depression.
  • Certain probiotics in our supplement help to promote weight loss and can help to lower cholesterol levels.

    Recommend for gut health, less bloat and improved flora

    Quick delivery, good quality and easy to swallow capsules. Since taking for a month I have noticed my bloating has reduced, my gut health has improved and bowel habits are healthier. Bought as it’s so important for a healthy gut flora. About to buy again for me and my sister.

    Definitely recommended buy. No side effects noticed.

    Great product!

    I’ve really enjoyed this product. At first I was skeptical about prebiotics, but I have clearly seen a change in my bloating. Would recommend!

    So far so good

    I'd seen these probiotics recommended on a menopause support group for reoccuring UTI issues. I've taken for 5 weeks along with the Magnesium complex and for the last 2 weeks not noticed any issues so really hoping they're working as I was previously suffering weekly. Has helped seeing sunshine in the last month but so far very impressed.

    I have been purchasing my supplements from vitabright for a good while now. I find the quality and quantities of their supplements very reasonable. I suffer from IBS and am also lactose intolerant, but I find these bio cultures help to keep my stomach flora settled and help to reduce the number of times I get a flare-up.

    Vitabright also has different offers that help to keep costs down.

Activated Charcoal Capsules

Sometimes it can take your gut a couple of days to get used to a new probiotic supplement, which is actually a good sign they are beneficial, but this process can release gases. Activated charcoal can relieve these symptoms.
