Once you have your hands on one of our Bio-Kult products, you may wonder how to best use it. Whilst the product’s packaging will provide directions for use that should be followed, often this guidance will offer some flexibility to account for your individual needs.

There are a number of factors to consider when deciding how to use our products, so we hope that the following information can help you to find the best approach for you.

Of course, if you’d prefer to discuss this with a member of our team, we are always happy to help. You can email us at info@bio-kult.com or call us on +44 (0) 1460 243 230.

Choosing the right dose

Firstly, it is important to follow our directions for use as these provide guidance which may differ depending on your age. Then consider your reason for using a live bacteria supplement as this too can help to inform your dosage. If you are supplementing for general preventative health and wellness purposes then a smaller dose may be sufficient. However, if you are taking antibiotics or travelling abroad and want to support a balanced microbiome, then a higher dose may be beneficial, at least initially.1,2

For example, the recommended dosage of Bio-Kult Everyday for adults and children 12+ is up to 4 capsules per day. So, in this instance, you could take a maintenance dose of 1-2 capsules per day, or you could take 4 capsules per day to maximise your dosage.

Whether or not you have used a live bacteria supplement before is another consideration when choosing how much to take. If you haven’t, then you may want to begin with a small dose (perhaps 1 capsule of Bio-Kult Everyday, per day, for example) and then gradually increase from there over the course of a few weeks or months. This can allow your gut to get used to the new strains being introduced.

When and how to take Bio-Kult

There are also a couple of things to bear in mind when deciding how to incorporate Bio-Kult into your daily routine. When testing our strains survivability, we found that this improved when paired with a meal. Without a meal our strains’ survival levels were slightly less, but still above those supported by clinical evidence. Therefore, for best results, we recommend that Bio-Kult is taken with food.

There are currently no known contraindications with live bacteria and any pharmaceutical medications.3 With that said, we recommend that Bio-Kult is taken at the opposite end of the day to your medications, or as far away from these as possible. If you are taking antibiotics, this separation can help the bacteria to survive.4 If you are taking any other medications, separating your doses could help to ensure their effectiveness.5

Please note, many of our products contain added vitamins, minerals and botanical ingredients, so the suitability of these alongside medications should be discussed with a healthcare practitioner before use.

There are a number of ways to take Bio-Kult, as we understand that preferences differ. For example, our capsule products can be swallowed, or these capsules can be opened and the powder mixed with food or drinks (as long as these aren’t hot!). This not only offers an alternative method of using the products for those who dislike swallowing capsules, it provides an opportunity for dosing flexibility which may be particularly useful when gradually increasing your dosage.

The Bio-Kult range also features gummies and fast dissolve formats if you prefer to add a tasty treat to your supplement routine.

How long to use Bio-Kult for

Bio-Kult has been designed to be taken long-term and it is considered safe to do so. However, you may choose to supplement live bacteria at specific times such as alongside and following a course of antibiotics, whilst on holiday or during the winter months when immunity can be weakened.6

Live bacteria in supplements generally only temporarily colonise the gut before passing through.7 Because of this, regular intake is recommended in order to sustain the effects associated with these strains as they move through the digestive system.

Finally, if you are pregnant or planning a pregnancy, you are taking any medications or have any medical conditions, please consult your doctor before taking any food supplement. Furthermore, should you experience any negative side effects when using Bio-Kult, please contact us at your earliest convenience and a member of our Nutrition & Education Team will be able to advise.

Conclusion

In summary, we hope that the information below can help you to find a way of using Bio-Kult that suits you.

  • Consider why you are using a live bacteria supplement and whether you have done so in the past before deciding your dosage.

  • Take Bio-Kult with food for best results, and away from any medications.

  • Choose your preferred method of taking Bio-Kult.

  • Consider whether you could benefit from long-term supplementation.

There is no ‘one size fits all’ when it comes to supplementing live bacteria. Just like our fingerprints, our microbiomes are unique to us and the way we choose to support them can be too.8
