WEIGHTWORLD – INSPIRING WELLNESS SINCE 2006: A British-grown family business with over a decade of expertise developing over 200 vitamins, food supplements & health devices. Using premium-grade ingredients, our products undergo rigorous research to fulfil the daily nutritional needs of individuals worldwide. We create UK-made & GMP-approved products by keeping your interests in mind. We cater to vegans & vegetarians & our supplements are formulated to enhance the well-being of you & your family.
PREBIOTICS FOR GUT HEALTH & INTESTINAL FLORA: While most competitors offer only 100mg of inulin prebiotic powder, our prebiotic and probiotic supplements contain 200mg of organic prebiotic inulin powder & 100mg of FOS (fructo-oligosaccharides). This unique blend stimulates the growth and proliferation of gut-friendly bacteria, promoting regularity. Each bottle contains 120 pro and prebiotics capsules that will keep you replenished for 2 months.
HIGHEST QUALITY GUT HEALTH SUPPLEMENTS: Our probiotics for women & men are 100% shelf-life stable and will provide live bacteria until expiration. Furthermore, our pro bio cultures complex capsules are vegan-friendly and free of GMOs, gluten, wheat, & dairy. As our bottle doesn’t require refrigeration, you can carry it while travelling as well. We stand behind the quality of our products. If, for any reason, you are not satisfied, please don't hesitate to contact us.
DEVELOPED FOR ENHANCED ABSORPTION:In most probiotic supplements, the bacterial strains come in low-quality capsules that quickly dissolve in stomach acid and never reach the intestines. Our pre and probiotics come in premium-quality capsules to ensure live bacterial strains are delivered to the intestines & released into your body for better absorption. Plus, you can easily split & sprinkle our proven probiotics capsules into your favourite food.
BIO CULTURES COMPLEX WITH 20 PROBIOTICS STRAINS: Our advanced probiotic complex contains 20 extensively researched natural bacteria strains that help balance gut flora for optimal wellbeing. Each serving (2 probiotics capsules) offers 60 Billion CFU of viable bacterial cultures, including Lactobacillus Acidophilus Probiotic, Lactobacillus reuteri, Lactobacillus gasseri, Lactobacillus rhamnosus, Lactobacillus Plantarum, Bifidobacterium Probiotic and more.

Main highlights

WHAT IS THE STORY BEHIND NUTRAVITA? - Nutravita is a recognised and trusted Vitamins & Supplements brand providing thousands of customers across the world since 2014. Our high quality products are manufactured, batch tested and certified in the UK, and safeguarded by the highest manufacturing standards in the world (GMP, BRC). We have a dedicated team of pharmacologists, chemists and research scientists working to source the finest and most beneficial ingredients.
HOW TO TAKE OUR SUPPLEMENT – For the most effective results, we recommend taking 2 capsules per day with a full glass of water. The capsules have been designed to be easy to swallow but if you would prefer, you could open the capsule a sprinkle over food. If you have a sensitive stomach, we recommend taking 1 capsule a day and gradually introducing the second capsule after a few weeks.
DELAYED RELEASE FOR BETTER ABSORPTION– Most other similar products on the market are not delayed release as their capsules dissolve in the stomach acid. Our Bio Complex 60 billion CFU capsules are resistant to stomach acid allowing them to travel to the intestine where the live bacteria can be the most effective. In addition, every capsule contains 100mg of Inulin which promotes the growth of the friendly bacteria.
CUSTOMER PEACE OF MIND – We have done our best to provide as much information as possible, but if you do have any questions please reach out to our very helpful customer care team. They will be happy to provide personalised assistance to help this supplement fit into your lifestyle. We always hope our customers are 100% happy with the product and service they receive, and so if you are not satisfied, please do not hesitate to contact us.
CONTAINS 21 LIVE BACTERIA STRAINS, BACKED BY SCIENCE - Our vegan, easy to swallow and stable capsules contain 21 live bacteria strains with an impressive 60 billion CFU per serving (2 capsules). Each bottle contains 60 capsules which is a full month’s supply. We have also included Lactospore (Bacillus coagulans), a live bacteria strain which has been subject to several clinical trials to support its effectiveness.
