    Recommended use

    Every Day can be given to adults and children, from 4 years onwards, with the following recommendations:

    • For best results take 1 capsule daily, preferably with breakfast
    • Intake can be increased to 2 capsules a day if desired, or as professionally directed
    • For those unable to swallow capsules, the capsule can be opened and contents mixed with a cool drink or food
    • Do not exceed recommended daily dosage
    • Drink plenty of water with your course of live cultures

    Storage instructions

    • For best results, do not remove desiccant sachet from the glass jar and close lid firmly after each use.
    • Store in a cool, dry place below 25°C and out of direct sunlight. For maximum potency, can be refrigerated after opening.


    Live cultures are not recommended for those with serious medical conditions e.g. those who are severely immunosuppressed, have pancreatitis, are in the ICU, have melaena, have a central venous catheter, infants with short bowel syndrome, or patients with open wounds following major surgery; unless under a doctor's care. Keep out of reach of children.

    Digestive supplements are not intended to prevent, treat or diagnose any medical conditions. If taking supplements, note that these should not be used as a substitute for a varied and balanced diet and a healthy lifestyle. If you are taking any medications or have a serious medical condition, consult a doctor before use. Optibac supplements will not cause dependency and may be used on an ongoing basis.

    Suitable for vegetarian diets. Dairy is not an ingredient. However, it is used in production. Any minute traces would not affect those with lactose intolerance.

    Following the taxonomic updates advised by a global team of scientists and published in April 2020, a reclassification has been proposed for the L. rhamnosus species. The Lactobacillus rhamnosus strain in Every Day may therefore now also be known as Lacticaseibacillus rhamnosus Rosell-11.

Customer Questions

All questions answered by probiotic experts Dr Kate Stephens PhD (Food and Microbial Sciences) BSc(Hons) Medical Biology and Louise Mason BA(Hons) DipCNM Nutritional Therapist, DipCNM Naturopath, mANP

Live cultures can be taken long term. Many people prefer to take a daily live cultures supplement on an ongoing basis to complement their gut bacteria as they are generally considered safe for most people. Research1,2 to date suggests that long-term use is fine, as the body does not become dependent on the good bacteria.

If looking for alternatives to brands like Symprove or Bio-Kult there are a few things to consider. A high-quality supplement always lists the full strain names of the bacteria, not just the species, so you can check the supporting research. Optibac Every Day is a great alternative to Symprove and other similar brands; it out-performs most comparable products on the quality of the strains it contains plus it comes in eco-conscious packaging.

The number of strains is not the most important thing to look for in a daily friendly bacteria supplement. It is best to select a supplement containing highly researched friendly bacteria. Optibac Every Day contains the world-renowned Lactobacillus acidophilus/helveticus Rosell-52 and Lactobacillus rhamnosus Rosell-11®, proven to survive stomach acidity and reach the gut alive1.

Yes, it is safe and generally advisable to take a daily friendly bacteria supplement. Good bacteria only colonise in the gut for a few weeks and research1,2,3 suggests that taking regular digestive supplements helps to complement the gut microbiome.

Many people like to have regular yoghurts, kefir and other fermented foods to support general gut health, and also a specifically researched friendly bacteria supplement. If you are choosing between capsules and yoghurt or kefir drinks like M&S X ZOE gut shots, consider the pros and cons of each. Our capsules are sugar-free, and tend to cost less, but yoghurt and kefir drinks provide protein and calcium. The best choice depends on personal preference and your individual needs.
