Lactoferrin is a remarkable protein found naturally in raw milk. In fact, it's one of the key ingredients that helps build a baby's immune system when they’re breastfed ('lacto' means milk). Your body actually produces it, too – it's in all your bodily fluids, ready to tackle any bugs that try to breach your defences.

The clever part? Your white blood cells store it and release it exactly where needed to stop infections spreading. It also helps keep your body balanced, regulating things like temperature and energy levels, while supporting your neurological health and digestive system with prebiotic properties.

Lactium is a milk protein hydrolysate that contains powerful peptides with soothing qualities - the reason why milk fed babies are so calm and content after feeding. Lactium has been shown in clinical studies to dial down cortisol, the stress hormone, and increase the flow of the calming neurotransmitter GABA. It soothes your nervous system, to help alleviate stress and anxiety, and at night it can work to switch off a busy brain and prepare your mind for rest. There are also no side effects - no addiction or grogginess the next day.

Leapfrog was created to optimise everyone’s wellbeing with little-known but extraordinary natural actives. Life is busy. We don’t have time to get sick or trial multiple supplements: we want one supplement brand we know we can rely on, for our immunity, stress, anxiety, and sleep.

Lactoferrin is an extraordinary protein made in our bodies and found raw milk. It's so rare and valuable, it's known as "pink gold". Despite having many therapeutic benefits, it's largely unknown as a supplement. Leapfrog is here to put Lactoferrin in the spotlight. We also champion Lactium, a natural milk protein hydrolysate that can alleviate stress and sleep issues, but with no side effects. Milk is part of our biology and offers so much health potential - Leapfrog is bringing these brilliant bioactives from milk into public consciousness.

There's a lot of buzz in the scientific community about Lactoferrin - they call it the "miracle molecule" and "pink gold" because of its efficacy, colour, value and scarcity. There are over 10,500 articles on PubMed, a site for peer-reviewed medical research and studies, that discuss the therapeutic effects of milk (bovine) lactoferrin. On the Science page, we've highlighted a few of the studies that relate to lactoferrin’s support of immune and brain function and the associated human trials.

While there are no known contraindications with our hero ingredients Lactoferrin and Lactium, do consult your healthcare practitioner if you have any concerns about any of our key ingredients.

We care about every ingredient we put into the tablets and are transparent about their source. This is the supplement our founder Stephanie created to help her own family - her parents, siblings, and children. Leapfrog is at the centre of their wellness toolkit. We believe that once you’ve tried it, it will be your ‘must have’ in the medicine cabinet.

We work with the best - not the cheapest - manufacturers and suppliers because of their commitment to high standards and practice: their accreditations and awards provide further proof. Our formulators have spent over a year developing each of our products, ensuring the provenance and efficacy of each ingredient, and have been overseen by our board of scientific advisors.

Our hero ingredients, Lactoferrin and Lactium, come from a globally respected dairy company in Northern France oriented in sustainable production and committed to exploring the potential of dairy ingredients since 1949.

- In 2021, they received a societal and environmental commitment award and achieved B Corp status in 2023.

- The cows from family farms benefit from an eco-responsible diet without GMOs, hormones or antibiotics, are grass-fed when possible, and raised on small pastures and on straw. All farmers must follow the Charter for Good Agricultural Practices.
