    What is Leapfrog IMMUNE?

    Leapfrog IMMUNE is a supplement containing lactoferrin, zinc and vitamin C. Think of it as your own body’s elite squad that you call in when you need extra immune support against viruses and bacteria. Taking Leapfrog IMMUNE at the beginning of a cold – and we all know how those play out – may help to reduce and shorten symptoms.

    What is lactoferrin?

    Lactoferrin is found in the milk of most mammals as one of the vital ingredients that gives a newborn optimal immunity (lacto means milk, and ferrin means iron). An iron-binding protein, lactoferrin exists in all your bodily secretions to combat environmental toxins when they enter the body. The largest storage of lactoferrin is in neutrophils, a type of white blood cell that attaches immediately to microbes. They burst open and release lactoferrin to prevent the spread of infection. Lactoferrin helps maintain immune homeostasis – it helps to regulate our body, so we have normal, healthy ranges for things like temperature, energy intake and growth. Lactoferrin also supports digestive and gut health, promoting prebiotic activity.

    What is Proferrin®?

    Separating lactoferrin from milk is a complicated endeavour and we chose the Proferrin® brand of lactoferrin as it offers the highest purity on the market (>95%). The lactoferrin is extracted from premium fresh milk – not colostrum or the by-product whey – and the milk is produced in a dynamic dairy production area in Northern France. In order to exercise its immune bioactivity, bovine lactoferrin needs to be native. A process involving low temperature and gentle chromatography and filtration preserves the native structure of Proferrin®, so it’s just as you would find in fresh milk.

    How can Leapfrog IMMUNE support the immune system?

    Every dose of Leapfrog IMMUNE contains 250mg of lactoferrin and the recommended daily intake of zinc and vitamin C (within two tablets). These actives work together to support the body’s own immune function. When our immune system has been compromised, Leapfrog IMMUNE is absorbed through receptors in the mouth and gastrointestinal tract, beginning a reaction between cells that ultimately activates genes; these produce mediators that circulate in the blood and raise our body’s immune defences.

    What’s the scientific evidence on lactoferrin?

    There are over 8,900 articles on PubMed, a site for peer-reviewed medical research and studies, that discuss the activity of milk (bovine) lactoferrin. On the Facts & Figures page, we have highlighted a few of the studies that relate to lactoferrin’s support of immune function and the associated human trials.

    What are the advantages of taking Leapfrog IMMUNE over cold and flu remedies on the market?

    Lactoferrin is already present within the body, so Leapfrog IMMUNE works in synergy with our bodies’ own natural immune systems. Adding the zinc and vitamin C gives Leapfrog IMMUNE a power punch of immune support.

    Are there any contraindications?

    Do consult your healthcare practitioner before taking this product if any of the following apply to you:

    You suffer from severe asthma, autoimmune or allergic conditions (lactoferrin levels in the body are elevated in the conditions of lymphocytic leukemia or pancreatitis), you suffer from milk protein allergies or you take blood thinning medications.


    How do I take Leapfrog IMMUNE?


    You’ve felt that first tickle in the throat or drip in the nose. You’re thinking “Nooooo!”

    These are the warning signs and you know how this plays out.

    This is the moment to take Leapfrog IMMUNE for a surge of immune support.

    Take two tablets per day – morning and evening, with or without food.

    Continue until you feel yourself again, which could be between one and five days.

    Panic over.

    Pulse Method

    You admit you’re not eating or sleeping properly, and you’re stressed out and under-exercised.

    Perhaps you’re not as young and robust as you once were.

    It’s the snotty season and you want to safeguard yourself.

    Take Leapfrog IMMUNE by pulse method to maintain continual immune support over time.

    Simply put, it’s one chewable tablet per day – one month on, one month off – over a season.

    In winter, for example, that’s one tablet per day for the months of October, December and February (check out our Winter Bundle that will have you covered).

    If we eat well, sleep well, exercise and are stress-free, then the body can be brilliant at fighting viruses and bacteria. Consider Leapfrog IMMUNE your backup.

    What time of day is best to take Leapfrog IMMUNE?

    We suggest one chewable tablet in the morning and one in the evening, as it’s easy to remember.

    Or, one chewable tablet per day if desired.

    How long should I take Leapfrog IMMUNE for?

    During an infectious episode, you can expect to take between 1 to 10 chewable tablets over the course of 1 to 5 (two chewable tablets per day).

    How soon should I feel better when taking Leapfrog Remedies IMMUNE?

    Owing to the number of viruses and bacteria and their various reactions in different people, it’s difficult to predict. Studies have shown that taking lactoferrin during a cold can reduce the symptoms, and Leapfrog IMMUNE may safeguard you from further infections once your immune system is compromised.

    Can I take Leapfrog IMMUNE if I am lactose intolerant?

    During the gentle manufacturing process, the lactose in lactoferrin is reduced to very low levels. The lactose content in our lactoferrin is typically 0.01% – virtually lactose-free – but, as milk is an allergen, do have a chat with your health practitioner if you have any concerns.

    If lactoferrin is found in dairy products, aren’t I eating or drinking enough to get the benefits?

    Lactoferrin is only found in small amounts in milk – the mean concentration is around 100mg/litre. It can also be assumed that most of the bovine lactoferrin (bLf) in milk foods and drinks is denatured through the sterilization and pasteurization of dairy products.

    Is Leapfrog IMMUNE nut free?

    Yes, and it is manufactured in a nut free facility.

    Is Leapfrog IMMUNE suitable for vegans?

    No. Lactoferrin is a cow’s milk protein and therefore this product is unsuitable for vegans.

    I'm pregnant. Can I take Leapfrog IMMUNE?

    Yes. Lactoferrin has been shown to effectively treat iron deficiency anaemia in pregnant women without the gastrointestinal side effects of high dose iron supplements. If you have any concerns, however, do consult a physician before taking this supplement.

    Can children take Leapfrog IMMUNE?

    Lactoferrin is safe for children to take (and is, of course, a key component of mother’s milk), so we suggest our chewable tablets are suitable from age 4. Our formula contains the recommended daily amount of zinc and vitamin C for children (aged 4-11) in 1 tablet, and for adults in 2 tablets.

    Should I carry Leapfrog IMMUNE with me?

    We’ve designed the packaging to be light and transportable, so you can pop a chewable tablet out of the blister pack the moment you need an immune boost.

    I’m travelling on an airline, should I take Leapfrog IMMUNE with me?

    Yes, yes, yes – this is a perfect opportunity to support your body’s immune system. An airplane is a petri dish for germs to thrive in: close proximity of passengers, frequent passenger turnaround and recirculated air. Think of tray tables, belt buckles and seat pockets as germ magnets, so take some sanitizing wipes and chew your Leapfrog IMMUNE.

    What's the shelf-life of Leapfrog IMMUNE?

    Please see the blister pack or the back of the carton for the Best Before End Date. Please keep Leapfrog IMMUNE in a cool, dry place. Unlike frogs, our chewable tablets should not get wet.

    Lactoferrin is iron-binding. How does that affect me?

    One of the reasons Lactoferrin is so successful as an anti-viral and anti-bacterial is that it binds iron to itself, iron that viruses and bacteria need to survive and thrive. Lactoferrin can help to starve the viruses/bacteria of their food source, giving the body a chance to mobilise itself against infection. The only issue might be if you have hemochromatosis as Lactoferrin raises serum iron and ferritin (but it’s a natural way to up iron levels during anaemia, without side effects). If you have any health issues in this area, do consult with your health practitioner first before taking this product.


    What are the other ingredients, and what do they do for me?

    All of our ingredients are generally regarded as safe (GRAS) by the EFSA (the European Food Safety Authority)

    Leapfrog IMMUNE contains Proferrin® – a high quality, native and pure lactoferrin produced in France from premium fresh cow’s milk. It strengthens the immune system and digestive health and has a positive effect on innate and adaptive immune responses through the stimulation of immune cells.

    Leapfrog IMMUNE contains zinc, an essential nutrient that performs many vital roles in the body. One of the critical benefits of this mineral is its support of the development and function of immune cells, which is why you’ll find zinc in natural cold treatments. We’ve chosen zinc citrate, which is well absorbed by the body.

    Leapfrog IMMUNE also contains vitamin C – a strong antioxidant which is widely thought to strengthen your body’s natural defences. Antioxidants protect cells from harmful molecules (free radicals) and thereby support the immune system. It also helps encourage the production of certain white blood cells that protect against infection. Our vitamin C is a blend of ascorbic acid and calcium ascorbate which are effective forms for the body.

    Leapfrog IMMUNE contains some other necessary agents, which are all safe ingredients:

    Sorbitol – a substitute for table sugar, sorbitol is regarded as a healthy alternative to traditional sweeteners. It does not ferment as easily on the teeth as sugar, meaning it slows down tooth decay and the formation of cavities. It acts as a texturizing agent for the tablets.

    Citric Acid – this boosts the acidity, enhances the flavour, stabilises and preserves the active ingredients in our chewable tablets.

    Sucralose – a no-calorie sweetener that is fermented from sugar and yet is not sugar, meaning it has no effect on tooth decay (and is often found in toothpaste and chewing gum). Because sucralose is 600 times sweeter than sugar, only a tiny amount needs to be used. Sucralose in Leapfrog IMMUNE accounts for only 0.15% of the formulation – 1.8mg per chewable tablet.

    Natural Flavourings – we’ve chosen lemon and orange flavours to give our chewable tablets a pleasant tang.

    Acacia Gum – this is a natural gum from the sap of the acacia tree, and it is used as a stabiliser for the flavour.

    Maltodextrin – this derives from maize and is used as a carrier for the flavour.

    Magnesium stearate – this is a flow agent which allows the chewable tablet to hold its shape. Magnesium is an essential mineral and stearic acid is a saturated fatty acid found in many foods such as eggs, coconut oil, chicken, walnuts and salmon. Both are entirely safe, and magnesium stearate is simply a salt that combines them both.

    Any potential side effects I need to be aware of?

    This product has been formulated with no known counter indications/interactions between the ingredients included. Lactoferrin has European Food Safety Authority and FDA approval as safe (GRAS) and our dosage is well within the specified daily limit of 3g per day within foods for medical purposes. Our lactoferrin is 100% natural, however, if you are taking any medications, it’s best to check with your doctor first before taking Leapfrog IMMUNE.

    Is the lactoferrin used in Leapfrog IMMUNE free of hormones and BSE?

    Our lactoferrin comes from milk produced by French cows that live on  family farms. The farms are all prohibited from the use of hormones and are routinely checked by veterinary experts.

    Can I take other supplements while taking Leapfrog IMMUNE?

    There are no known contra-indications with other supplements, however if you have any concerns do chat with your healthcare practitioner first.

    Is the lactoferrin in Leapfrog IMMUNE Apo-lactoferrin or Holo-lactoferrin?

    Apo lactoferrin is lactoferrin without iron (unsaturated) and Holo lactoferrin is lactoferrin saturated in iron. To obtain both apo and holo lactoferrin, a chemical process is needed. Our lactoferrin is neither apo nor holo as it is native: no chemical process is involved during the process. It’s as native as the lactoferrin in our body and efficient as it is.


    Who formulates your products?

    Leapfrog Remedies’ products are formulated by scientists and compounding pharmacists who research, trial and test ingredients for a wide range of supplements.

    Who manufactures your products?

    Leapfrog IMMUNE is manufactured in the UK by a supplement company that has BRCGS ‘AA’ Food Safety Accreditation – all their products comply with UK and EU legislation – so this isn’t their first rodeo.

    Where do the ingredients originate from?

    The zinc and vitamin C are sourced from the UK, and the lactoferrin from France.

    What is the carbon involved in lactoferrin?

    The majority of the carbon impact of milk comes from other components, such as cream and lactose. Because it is such a small fraction of the milk, the calculation of the carbon impact of our lactoferrin production is 0.94 kg of CO2 / kg of lactoferrin. In other terms, one kilogram of lactoferrin is the equivalent of 1kWh of electricity – and that makes 4000 Leapfrog IMMUNE chewable tablets.

    Which charities does Leapfrog Remedies support?

    Leapfrog Remedies contributes to Ecologi, an environmental charity that is certified B Corps. Every month we support two different impact driven climate projects, from generating clean electriticty from hydropower in India to protecting lowland peat forest in Indonesia. Ecologi also plants trees every month on our behalf.
