    IBS relief

    I’ve long suffered with stomach issues, especially with stress and certain foods. I can see an improvement a few months after taking this biotic. Can’t recommend enough!

    Biotics

    I’ve noticed less bloating taking these, I used to bloat and feel sick after eating a lot but since taking these I feel my gut is much better.

Frequently asked questions

Biotic⁺ is for everyone aged 12 and over, regardless of biological gender, including those on gluten-free, vegan, kosher, or halal diets.

If you’re pregnant or breastfeeding, or if you have any ongoing health problems, check with your doctor before starting any probiotic product.

For children under the age of 12, we recommend taking half the daily dose. You can do this by opening up the capsule and adding Biotic⁺ to some food, such as fruit or yoghurt.

Like a lot of good things in life, Biotic⁺ is a long-term commitment rather than a quick fix. But even if you don’t feel the difference immediately, all those bacteria are getting to work behind the scenes.

Within the first 24-48 hours, you might feel some initial adjustment effects as your gut gets used to the new bacterial strains. This is perfectly normal.

Keep taking Biotic⁺ every day, and these effects should settle down within 1-3 weeks. 

Longer term benefits, like normal heart, cognitive and immune function, can take a little longer. But patience pays off and Biotic⁺ will continue to support your overall health—you might notice some of the changes other customers describe.

The British Society of Gastroenterology recommends taking a new bacterial product for 3 months so the benefits can kick in. Remember, your microbiome is as unique as your fingerprint, so everyone experiences changes differently.

You can take Biotic⁺ with or without food, so it’s totally up to you.

Some people find that taking with a meal (e.g. first thing at breakfast) can help build the habit.

But our formulas are designed for maximum absorption, so you can take them on an empty stomach without compromising efficacy.

Did you know that most of the symptoms blamed on probiotics (gas, bloating, indigestion) actually come from prebiotics?

Although prebiotics are an important part of any diet, you can’t fit enough into an easy-to-swallow capsule to make any difference at all. So instead of including a worse-than-useless amount of prebiotics in Biotic⁺, we support a food-first approach (i.e. getting a varied diet with lots of veggies).

Absolutely. Biotic⁺ and Vitals⁺ are specifically formulated to be more effective together, maximising absorption and balancing your gut, mind and body.
