O2B Synbiotic⁺ combines probiotics and prebiotic fibre to support a healthy gut microbiome, digestive balance, bowel regularity and immune function, helping nourish your gut from within.

Probiotics + prebiotics: a complementary approach to gut health

A healthy gut is home to trillions of microorganisms that play important roles in digestion, nutrient metabolism, immune function and overall wellbeing. O2B Synbiotic⁺ combines beneficial probiotic microorganisms with prebiotic inulin, providing two complementary forms of nutritional support for a balanced and diverse intestinal environment.

Probiotics – supporting a balanced gut microbiome

Each green capsule provides 1,500 mg of Fermplus probiotic powder, containing beneficial microorganisms selected to support gut microbial balance. Probiotics can help maintain a healthy intestinal environment and support normal digestive and immune-system function. A balanced gut microbiome also plays an important role in the breakdown and utilisation of nutrients from the foods we eat.

Prebiotics – nourishing beneficial gut bacteria

Each white capsule provides 1,250 mg of inulin, a naturally occurring prebiotic fibre that passes through the upper digestive tract largely undigested before being fermented by intestinal microorganisms.

Inulin helps nourish beneficial gut bacteria, including Bifidobacteria, and supports the production of short-chain fatty acids (SCFAs). These compounds, particularly butyrate, play important roles in maintaining the intestinal environment, supporting the gut lining and normal bowel function.

Digestive comfort and bowel regularity

Healthy digestion depends on a complex interaction between the foods we eat, our digestive system and the microorganisms living in our gut. By combining probiotics with fermentable prebiotic fibre, O2B Synbiotic⁺ provides complementary support for intestinal microbial balance and regular bowel function.

Gut health and immune-system wellbeing

The digestive tract is closely connected to the immune system, with a substantial proportion of the body's immune cells located in gut-associated tissues. The intestinal microbiome interacts with these immune cells and helps maintain the gut barrier.

O2B Synbiotic⁺ supports this important relationship by providing beneficial microorganisms alongside prebiotic fibre to nourish the intestinal microbiome.

A daily routine for gut wellbeing

O2B Synbiotic⁺ brings together probiotics and prebiotics in a convenient two-capsule system. The green capsule provides beneficial microorganisms, while the white capsule supplies the prebiotic fibre that helps nourish the gut's resident bacteria.

Together, they offer a complementary approach to supporting digestive health, microbiome balance and everyday wellbeing.

What is O2B Synbiotic+ used for? 

O2B Synbiotic+ is designed to support gut health, digestive wellbeing, nutrient absorption, microbiome balance and immune system function. It combines probiotics, prebiotic inulin and raw wholefood nutrients in one formula. 

What is a synbiotic supplement? 

A synbiotic supplement combines probiotics and prebiotics. Probiotics are friendly live bacteria, while prebiotics are fibres that help feed beneficial bacteria.

O2B Synbiotic+ contains probiotics plus inulin as a prebiotic. 

What is the difference between a probiotic and a synbiotic? 

A probiotic provides beneficial bacteria. A synbiotic provides beneficial bacteria plus a prebiotic food source to support those bacteria. This makes Synbiotic+ a more complete gut health supplement than a probiotic-only product. 

What is inulin? 

Inulin is a plant-based prebiotic fibre. It helps feed beneficial gut bacteria and supports a healthy gut microbiome. 

Is O2B Synbiotic+ gluten free? 

Yes. O2B Synbiotic+ is gluten free.  

When should I take Synbiotic+? 

Take 1 x green capsule and 1 x white capsule together daily with food or as directed by your health care professional. 

Can I take Synbiotic+ every day? 

Synbiotic+ can be positioned as a daily gut health supplement when taken as directed. Customers should follow the label directions and consult a healthcare professional if they are unsure. 

Will Synbiotic+ cause bloating? 

Some people may notice temporary digestive changes when introducing probiotics or prebiotic fibre. If you are sensitive to fibre or gut health supplements you may prefer to start slowly and follow the label directions. 

Who should check with a healthcare professional before using Synbiotic+? 

If you are pregnant, breastfeeding, immunocompromised, taking medication, managing a health condition, or experiencing ongoing digestive symptoms should consult your healthcare professional before use. 

Can I take Synbiotic+ with other O2B supplements? 

Synbiotic+ may pair well with broader digestive health or immune support routines, depending on your needs. It could be considered alongside products such as O2B Pure Bitters, O2B Bowel Wellness or O2B Immune Boost, where appropriate. 

What size is O2B Synbiotic+ available in? 

A 90 capsule product.

Great for dogs!

Used this for my dog that has liver issues and because of meds had bad guts issues. A much better alternative than just probiotics. Was advised to use half the human dosage and she has been great in it! Wish half dosages are made available for dogs!

Hi Monica, I know your review was a while ago but just wanted to let you know that we now have a range of probiotic supplements for pets! Here's the link to the K9 version https://www.o2bhealthy.co.nz/shop/categories/pet-health/o2b-k9-synbiotic-large-breed/

Thanks for the advice

Kevin from O2B advised me to support my gut when I talked to him about some joint issues and was in a surgical state. I have taken Synbiotic tablets for a month now and am pleased to continue on them.
