  • Q. What are probiotics?

    Probiotics are live microbial food ingredients that have a beneficial effect on health when taken in the right amounts. It’s not clear yet exactly how probiotics have these effects, but research shows that they play an important role in improving digestion and intestinal health as well as the helping to regulate and stimulate the immune system.

  • Q. Where can I get Lab4?

    This unique blend of probiotics can be found in a new range of probiotic supplements called ProVen Probiotics. There are 12 products within the ProVen Probiotic range with different formulations to suit all ages and lifestyles.

  • Q. Can probiotics help combat allergies?

    New, breakthrough clinical evidence about to be published in the Journal of Allergy and Clinical Immunology and being presented at the Royal College of Paediatrics and Child Health (RCPCH) annual conference in Glasgow (22-24 May 2012), demonstrates that probiotics can significantly reduce the risk of allergy in children. Lab4 probiotics were taken by mothers during the latter part of pregnancy and given daily to their babies in the first six months following birth. The probiotic halved the risk of allergic sensitisation in infants up to two years of age. Remarkably, the risk of atopic eczema was also reduced by over 50% and this is likely to significantly reduce asthma and rhinitis into older childhood and as adults.

  • Q. Can I take the Lab4 probiotics if I am on other medication?

    The are no contraindications known for probiotics, in fact, their safety record is impeccable. However, as with any supplement check with your doctor/pharmacist if you are unsure.

  • Q. How can you ascertain what makes a good probiotic?

    The European Consensus taken in 2004 outlines the criteria to help people distinguish good quality probiotics as those with evidence for health benefits. According to the consensus’ prerequisites Lab4 probiotics meet all requirements for a good probiotic.

  • Q. What does the European Consensus recommend?

    The European Consensus outlines that a high quality probiotic must contain bacterial strains that meet the following criteria:

    Have clinically proven health benefits demonstrated using rigorous scientific trials (randomised, double blind, and placebo controlled designed trials)

    Are alive and reach the gut in sufficient number, surviving gastric and bile acid and digestive enzymes during the gastro-intestinal transit until they reach the gut

    Are clearly defined using modern biological detection methods

    Are clearly labeled, including the genus (eg. Lactobacillus), the strain (e.g acidophilus Cul -21) and amount (e.g 10 billion)

    Are shelf stable, thus guaranteeing delivery of the quantity of probiotic until the date of expiry

    Lab4 probiotic strains satisfy all these criteria.
