May not be suitable

Consult your doctor before use. Some (but not all) patients who are immunocompromised may lack the ability to mount an appropriate response to new bacteria in the gut, which may lead to serious complications.

From the founder

“As both a Nutritional Therapist and an IBD patient myself, I knew how challenging it was to find an effective solution to specific gut health requirements. I found clients had to combine supplements to get what they needed, which was time-consuming and expensive.

I wanted to ensure our probiotic blend included only strains with clinical evidence to support their use. And we were the first company to combine friendly bacteria with an effective dose of saccharomyces boulardii organisms, something I’m really proud of.”

Frequently asked questions

Yes it is, and it’s free of all major allergens.

Yes, and we’ve gone the extra mile to register it with the Vegan Society.

All the live organisms are in a delayed-release capsule, which not only ensures they survive the acid in your gastro-intestinal tract, but also improves their stability. This means they don’t need to be refrigerated, unless you’re in exceptionally hot conditions.

Although it can be taken by those looking to support general gut health, it’s been designed for specific gut health requirements and as such it’s pretty powerful. For general gut support, try our Advanced Daily Biotic.

While the probiotics it contains are well-tolerated, if you’re generally healthy and eat a nutritious, varied diet, it’s not usually necessary to use live bacteria products on an ongoing basis. We advise supplementing with Inessa Advanced Biotic Complex only at times you need it most, such as when you’re travelling abroad, during or after a course of antibiotics or if you’re recovering from a bug, for example. However, if you have a specific, chronic gut issue such as IBS or IBD, you may benefit from all-year use.

Take one capsule per day or as advised by a healthcare professional. Probiotics are best taken before breakfast, with a cold or room temperature beverage, as live bacteria may be damaged by heat. Although you should take the capsule with a cool beverage, there is no issue with having a hot drink afterwards. If you forget to take it earlier in the day, you can have it with other meals, though we don’t advise taking it after a meal.

Probiotics are deemed safe for most people, but if you are immunocompromised or taking certain types of immunosuppressant medication, you should always check with your doctor first. If you take other types of medication, always check with your doctor or the information leaflet with your medicine(s) for contraindications.
