OptiBac is a leading UK-based probiotic supplement brand, known for its science-backed formulations tailored to various health needs—from general digestion to immune support and women’s health. With over 6.5 million products sold globally and a reputation for quality, OptiBac has become a trusted name among healthcare practitioners and consumers alike.

Each OptiBac product is developed using well-researched strains of friendly bacteria, with clinical trials supporting their safety and effectiveness. Probiotics play a vital role in gut health, which is increasingly recognised as central to overall wellbeing. According to recent research, an estimated 70% of the immune system resides in the gut, highlighting the importance of maintaining a balanced microbiome. For those focusing on digestive wellness, the Gut Health range at Welzo offers excellent complementary support.

Pairing OptiBac with other high-quality probiotics can help optimise your routine. At Welzo, you’ll also find a carefully curated Probiotics collection, offering a wide selection of trusted products to support your health. For those looking to complement their regimen further, our Prebiotics selection provides nourishment for your good bacteria to thrive.

Benefits of Probiotics

Probiotics are live microorganisms that offer a wide array of health benefits when consumed in the right amounts. They help maintain the natural balance of bacteria in the digestive system and may be beneficial in managing issues such as bloating, irregular bowel movements, and antibiotic-associated diarrhoea. Beyond digestive support, certain strains can also help improve skin health, regulate mood through the gut-brain axis, and support immune function.

Probiotics also play an important role in managing gut inflammation and restoring comfort for individuals experiencing chronic digestive issues. Supplements such as those found in our Digestive Enzymes range may further support the breakdown of food and nutrient absorption, complementing your probiotic intake.

For a comprehensive approach to gut health, many customers combine probiotics with prebiotics, which feed the beneficial bacteria and help them thrive. Others look to ingredients like Glutamine, known for helping to repair the gut lining and support intestinal barrier function.
