Leapfrog IMMUNE is the UK's first lactoferrin immune supplement - a natural, fast-acting chewable tablet containing Lactoferrin 250mg, Zinc 5mg and Vitamin C 40mg, clinically formulated to strengthen the body's innate immune defences, stop colds developing, and shorten the duration of illness when symptoms strike. Lactoferrin is a natural protein your body already produces - present in your tears, saliva, and the lining of your nose and gut - and is one of the most studied immune proteins in science, with more than 10,500 peer-reviewed papers documenting its antiviral, antibacterial and anti-inflammatory properties. It works by binding iron, starving bacteria and viruses of the nutrient they need to replicate, while simultaneously activating the natural killer cells and neutrophils that form the front line of immune defence. Zinc supports the immune system's daily cellular work and helps the body create and protect immune cells. Vitamin C contributes to normal immune function and enhances lactoferrin's protective action at the mucosal barrier - the first point of contact with incoming pathogens. At 250mg per tablet, IMMUNE delivers the highest-purity lactoferrin available at greater than 95% purity, extracted from fresh grass-fed cow's milk by a B-Corp certified dairy cooperative in Northern France. Unlike capsule or powder supplements, IMMUNE's chewable format begins absorption through the mouth, reaching the mucosal surfaces where immune defence begins before stomach acid can degrade the protein. No pills to swallow. No water needed. Available in a natural citrus flavour. Suitable for adults and children from age 4. Safe during pregnancy and breastfeeding. Made in the UK. Immunity SOS - felt the first tickle in your throat or a drip in your nose? Chew two tablets immediately - one in the morning, one in the evening - and continue for up to five days. Clinical evidence shows lactoferrin supplementation reduces the incidence, frequency, duration, and severity of respiratory tract infections. Pulse Method™ - for those feeling vulnerable during a season, chew one tablet every day two weeks on, two weeks off. This cyclic approach replenishes lactoferrin levels continuously through high-risk periods.
