The idea that you need a gut health supplement to support your ‘general’ gut health sounds good, but it’s outdated. Just like you wouldn’t take an iron supplement to treat a vitamin D deficiency, why would you treat your gut with a generic supplement that doesn’t address your needs? Frustrated by the disconnect between the latest science and the misleading options available, Dr Megan Rossi (PhD, RD, APD) developed SMART STRAINS to revolutionise how people understand and use live bacterial supplements. Through this game-changing range, she is empowering everyone to care for themselves and their families, providing the right strain, at the right time, in the right way – and only when you need it. Whether you’re seeking probiotics for gut health, probiotics for babies, probiotics for women or probiotics for immunity, SMART STRAINS delivers tailored solutions that work with your body. Whether you’re seeking a gut health supplement for immune and digestive support, probiotics for protecting your gut health, probiotics for your vaginal flora or probiotics for your baby, toddler or child, SMART STRAINS delivers tailored solutions that work for your needs. SMART STRAINS for Immunity is a scientifically formulated probiotic complex designed to support the immune system. It contains proven probiotics including (LGG), the world’s most documented bacterial strain, and (BB-12) – the world’s most published Bifidobacterium strain. These strains are specifically selected to help support the upper respiratory tract, a critical component of immune defense. This probiotic supplement also includes 10μg of vitamin D3 per sachet, which contributes to the normal function of the immune system. The NHS recommends that all children and adults over the age of 4 take a daily vitamin D supplement during the winter months, and babies and children up to 4 years should supplement all year long. Each sachet delivers 20 billion live bacteria in a convenient probiotic powder format, designed for optimal delivery directly to the mouth and throat where immune defense begins.
