Lactoferrin is a natural protein produced by the human body and found in milk, tears, saliva, and the lining of the nose, mouth, and gut. It's one of the body's first lines of immune defence - an iron-binding protein that starves bacteria and viruses of the iron they need to survive, while simulataneously activating white blood cells and modulating the body's inflammatory response.
Lactoferrin is most abundant in colostrum - the first milk a mother produces after birth - which is why its considered by scientists a foundational immune protein. The body produces less lactoferrin when under stress, poor sleep, or illness: exactly the moments when immune protection is needed most. Supplementing with lactoferrin replenishes a protein the body already recognises and uses, which is why it works in synergy with your own immune system.
Scientists have published more than 11k peer-reviewed articles on lactoferrin's properties. They call it the "miracle molecule", the "Swiss army knife of the human defence system" and even "pink gold" (because of it's rarity, efficacy, high value and pale pink colour). There's only 100mg of lactoferrin in a litre of cow's milk, which makes high-purity supplementation the only reliable way to get a clinically meaningful dose.
Read more: How Lactoferrin Works. Lactoferrin vs Colostrum. Our Science.
Lactoferrin supports immune defence, sleep quality, cognitive function, bone health, skin vitality, iron regulation, and gut health - making it one of the most broadly evidenced natural proteins available as a supplement. Unlike most supplements which target a single system, lactoferrin works across multiple biological pathways simultaneously because it's already part of how the human body functions.
Its most well-established benefit is immune protection. Lactoferrin binds iron in the body, depriving bacteria and viruses of the nutrient they need to survive, thrive and replicate. It simultaneously activates natural killer cells and neutrophils - the white blood cells that identify and destroy pathogens - and moderates the inflammatory response that, when left unchecked, causes symptoms to feel worse than the infection itself. Multiple peer-reviewed trials have shown that lactoferrin supplementation reduces the incidence, duration, and severity of respiratory tract infections in both adults and children.
Beyond immunity, lactoferrin's iron-regulating properties make it valuable for energy and cognitive clarity — iron imbalance is a leading driver of fatigue and brain fog, and lactoferrin helps maintain optimal iron metabolism without the gastrointestinal side effects of conventional iron supplements. In bone health, clinical research has shown lactoferrin to be a potent anabolic factor — stimulating bone-forming osteoblasts and reducing bone resorption, with one trial recording a 45% improvement in bone formation markers versus placebo. In skin health, randomised controlled trials have demonstrated significant reductions in inflammatory skin lesions and sebum levels, making it relevant for hormonal skin changes as well as general complexion health.
Lactoferrin also supports the gut by promoting the growth of beneficial probiotic strains while inhibiting pathogenic bacteria, and shows neuroprotective properties that are the subject of active clinical research into cognitive ageing.

Separating lactoferrin from milk is a complicated endeavour when trying to retain its bioactivity. At Leapfrog, we chose one that has 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 our lactoferrin at Leapfrog so it’s just as you would find in fresh milk.
Lactoferrin is a protein produced naturally by the human body and found in milk, tears, saliva, and mucous membranes. For supplements, it's extracted from cow's milk - whose lactoferrin is up to 75% structurally similar to human lactoferrin, which is why it delivers the same therapeutic benefits.
Leapfrog sources its lactoferrin from a dairy cooperative in Northern France that has been working with milk proteins since 1949. The cows are raised on family farms, fed without GMOs, hormones, or antibiotics, and graze on pasture where possible under a strict Charter for Good Agricultural Practices. The cooperative achieved B Corp status in 2023, recognising its commitment to environmental and social standards.
Extracting lactoferrin from milk is a technically demanding process - there's only approximately 100mg of lactoferrin in a litre of cow's milk, which is one of the reasons why high-purity lactoferrin is expensive and relatively rare. Leapfrog's lactoferrin is extracted using low-temperature chromatography and a microfiltration process that preserves the protein's native structure and bioactivity. Heat or aggressive processing degrades lactoferrin's effectiveness, so the cold extraction method is essential - and is one of only two such processes available globally.
The result is lactoferrin with greater than 95% purity - among the highest on the market - and in the native form in which it's found in fresh milk. Just as Mother Nature intended.
Read more. How Lactoferrin is Made.

Lactoferrin and colostrum are not the same, though they are closely related. Colostrum is the first milk a mother produces in the days after birth, and it's exceptionally rich in lactoferrin. Lactoferrin is one of the specific proteins within colostrum that gives it its immune-boosting properties.
Think of it this way: colostrum is the whole food, and lactoferrin is the key active ingredient - the 'first violinist' of colostrum. When you take a colostrum supplement, you are getting lactoferrin - but alongside a complex mixture of other compounds, hormones, growth factors, and proteins, and at a dose that varies considerably depending on the product and its source.
Leapfrog uses isolated, high-purity lactoferrin (>95% purity) extracted from fresh cow's milk - not colostrum or the by-product whey. This matters for three reasons. First, the dose is precise and consistent: every tablet contains exactly 250mg of bioactive lactoferrin, whereas colostrum supplements vary widely in how much lactoferrin they actually contain. Second, isolated lactoferrin is virtually lactose-free (0.01% lactose), making it suitable for people with lactose intolerance - which colostrum is not. Third, pure lactoferrin is free from the hormones and growth factors present in colostrum, making it appropriate for a broader range of people including those taking it long-term and as they age.
The specific benefits of immune resilience, iron regulation, anti-inflammatory support in colostrum are driven primarily by lactoferrin, so it's a more targeted, more consistent, and more efficiently dosed approach.

There are 11,000+ scientific articles on PubMed, a site for peer-reviewed medical research and studies, that discuss the therapeutic activity of milk (bovine) lactoferrin, including 50+ clinical trials.
In terms of immune optimisation, Lactoferrin has been shown to reduce the duration of respiratory infections in multiple peer-reviewed trials (PubMed PMID: 35566292) and Leapfrog's pharmaceutical consultant, Dr Hamid Merchant, co-authored a meta-analysis of Lactoferrin's effects against respiratory tract infections that showed it to have "promising efficacy in reducing the risk of RTIs" (PubMed PMID: 34620326).
In terms of cognitive support, Lactoferrin has been shown in a piglet study to increase memory, attention and learning (PubMed PMID: PMCID: PMC4510916) Read our interview with the scientist behind the study in our Journal post: Can Lactoferrin Make You Smarter?
Lactoferrin is only found in small amounts in milk – the mean concentration is around 100mg/litre. Also, most of the bovine lactoferrin (bLf) in milk foods and drinks is denatured through the sterilization and pasteurization of dairy products.
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.
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.

Leapfrog DAILY is a supplement formulated by nutritionists and doctors for daily immune resilience. DAILY offers a daily dose of lactoferrin - a protein within the body that protects you against germs - together with zinc and vitamin C, vitamin, D, vitamin E and vitamin K2.
DAILY contains 100mg of Lactoferrin in a delicious blood orange flavoured chewable tablet. Adults and children over 12 can take one tablet daily for immune resilience.
Every dose of Leapfrog DAILY contains 100mg of lactoferrin and the recommended daily intake of zinc and vitamin C, D, E and K2. DAILY simplifies your routine with clinically-backed, naturally-sourced bioactive ingredients that support your body at a cellular level.
Chew one tablet of DAILY per day to sustain immune health and baseline wellness.
Leapfrog DAILY is a carefully formulated supplement that offers a daily dose of Lactoferrin. Unlike multivitamins with a catalogue of ingredients, DAILY simplifies your routine with clinically-backed, naturally-sourced bioactive ingredients that support your body at a cellular level.
Whether you’re working from home, in a crowded office, or juggling the demands of family life, DAILY is a ritual you can depend on to reinforce your immune health.
If you like the effects of IMMUNE, you can absolutely keep subscribing. IMMUNE benefits from 250mg of Lactoferrin in every dose. DAILY offers 100mg Lactoferrin, plus the addition of Vitamins C, D, E, K2 and Zinc. If you feel like you need the stronger dose then IMMUNE might suit you best. Both DAILY and IMMUNE are protective; while IMMUNE is the reactive choice at the first sign of sniffles.

We suggest one chewable DAILY tablet in the morning so that it becomes part of your routine.
We suggest chewing one tablet of DAILY every day to reinforce your immune health.
There are no known contraindications with DAILY, but do consult your healthcare practitioner before taking lactoferrin 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), or you take blood thinning medications.
Please note Leapfrog products are not suitable for those with a milk allergy.
All of our ingredients are generally regarded as safe (GRAS) by the EFSA (the European Food Safety Authority).
DAILY contains 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.
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.
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.
Vitamin D - a sunshine vitamin your body makes naturally but rarely gets enough of. Vitamin D supports your immune cells in identifying and responding to threats, helps your body absorb calcium for strong bones, and plays a quiet but essential role in keeping your energy and mood on an even keel.
Vitamin E - a powerful antioxidant that works to protect your cells from everyday damage. Vitamin E shields your immune cells from oxidative stress, supports your skin's natural barrier, and helps your body's defence system stay sharp.
Vitamin K2 - A lesser-known vitamin that works as a traffic controller for calcium in your body. Where Vitamin D helps you absorb calcium, K2 directs it - into your bones and teeth where it belongs. Together, D and K2 are one of nutrition's most important partnerships.
Leapfrog DAILY contains some other necessary agents, which are all safe ingredients:
Xylitol – a substitute for table sugar, xylitol is regarded as a healthy alternative to traditional sweeteners that has a low glycemic index. It has antibacterial and anti-inflammatory potential and has a significant antiplaque effect on the teeth surface and can reduce gingival inflammation.
Isomalt – a sugar-free sweetener that doesn’t increase blood glucose or insulin levels and is safe for teeth. It has been shown to promote good bacteria in the gut, and it acts as a texturizing agent for the tablets.
Citric Acid – this boosts the acidity, enhances the flavour, and stabilises and preserves the active ingredients in our chewable tablets.
Natural Flavourings – we’ve chosen blood orange flavour to give our chewable tablets a pleasant tang.
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.

Leapfrog IMMUNE is a supplement containing lactoferrin, zinc and vitamin C. Every dose of Leapfrog IMMUNE contains 250mg of lactoferrin and the recommended daily intake of zinc and vitamin C (within two tablets for an adult, one tablet for a child).
These actives work together to support the body’s 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, quashing coughs, colds and other infections.
Think of IMMUNE 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.
Chew one or two tablets per day when you feel the first tickle in the throat or drip in the nose. Continue until you feel yourself again, which could be between one and five days.
You can also take IMMUNE over a season, for continuous immune support over time. Many customers use the pulse method - taking one tablet every day two weeks on, two weeks off.
While other cold and flu remedies can simply mask the symptoms, Lactoferrin gets to work on a cellular level to destroy viruses and bacteria. 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 an extra power punch of immune support.
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.

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).
Owing to the number of viruses and bacteria and their various reactions in different people, it’s difficult to predict.Studieshave 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.
There are no known contraindications with IMMUNE, but do consult your healthcare practitioner before taking lactoferrin 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), or you take blood thinning medications.

Leapfrog SNOOZE is a supplement containing Lactium®, lactoferrin and vitamin B6. Think of the calm state of a baby after feeding…Leapfrog SNOOZE is formulated to emulate that mood, promoting relaxation and more restful sleep. Taking Leapfrog SNOOZE during periods of anxiety or sleep disturbance may help to calm and unwind the mind.
To take Leapfrog SNOOZE chew one or two tablets one hour before bed. For children 7-14 years, chew one tablet one hour before bed. Can also be taken during the night. Not suitable for children under 7 years old.
Lactium® is a natural milk protein hydrolysate that was created by French scientists to emulate the calm mood of a baby after feeding. The enzymes present in a baby’s digestive system help to release a bioactive peptide that induces a state of bliss. As our digestive system matures our digestive enzymatic system is no longer able to release the peptide and we lose the benefit.
French researchers developed an innovative process to reproduce a baby’s digestive mechanism. They used a well-known digestive enzyme – trypsin – to isolate the milk protein hydrolysate containing the bioactive peptide – alpha-casozepine – from casein. It has a gentle action on the body but has been clinically proven to reduce stress-related symptoms and encourage better sleep.
Alpha-casozepine is a bioactive decapeptide – originating from S1 casein, a cow’s milk protein – that has an affinity for gamma-aminobutyric acid (GABA) receptors in the brain. Scientific evidence suggests it has an anxiolytic (anxiety-reducing) effect similar to benzodiazepines, but without the side effects.
By having an affinity for certain receptors in the central nervous system called GABAA receptors, Lactium® increases the activity of Gamma-Aminobutyric acid (GABA), a neurotransmitter, or chemical messenger, that is well known for its inhibitory action on anxiety and its relaxing properties.
Cortisol is a stress hormone produced in the adrenal glands that helps engage your “fight or flight” response and contributes to maintain your energy balance during all day. It also acts as a vital part of your circadian rhythm, reaching a peak in the morning and reducing to minimum at around midnight. The peak in the morning gives us energy, and the reduction by the evening leads to tiredness.
If there is an acute stress, the body will return to baseline. But if the stress is too frequent or chronic, then the body cannot recover and regenerate resources, leading to health problems such as weight increase, sleep disorders, and immune system dysregulation.
Lactium® has been shown to have an effect on cortisol relase; blood cortisol levels reduce significantly after an acute stress event when supplementing with Lactium®. Even with chronic anxiety, Lactium® reduces blood cortisol level in the morning.

Customers often feel the calming effects of SNOOZE on the very first night. In clincial studies, an effect of Lactium was shown after 15 days of supplementation, when the results were taken. We have no data after one day of supplementation (for 150mg and 300mg), but for 600mg of supplementation of Lactium, tan effect after 2 days has been shown.
The effects can begin to decrease about 6 hours after intake. Lactium is quickly metabolized without accumulating effect, though the sensation of wellbeing can last after stopping taking Lactium.
There have been 9 rigorous clinical studies conducted between 1999 and 2021 on more than 500 adult volunteers that have proven the effectiveness of Lactium®.
Randomized, double-blind, placebo-controlled trials have been run, details of which can be found on our dedicated Lactium® webpage. Clinical studies were made according to Good Clinical Practice Guidelines with official ethical committees. In the human trials, tests were used that have been validated by the scientific community (i.e. Stroop test, Cold pressor test, Spielberger questionnaires,…). They were not developed specifically for these studies. Blood pressure reactivity to stress (systolic and diastolic blood pressure) was also tested, as well as ACTH and cortisol which are stress-related hormones. They are validated physiological markers of stress. Find more case studies here.
Lactium®is a natural and patented ingredient made from the casein in milk – Mother Nature’s most extraordinary cocktail for health and wellness. Unlike benzodiazepines – a type of sedative medication – Lactium®isn’t addictive, even at a high dosage, nor does it have any other side effects such as disinhibition.
There are no specific contraindications concerning Lactium®, though do consult your healthcare practitioner before taking this product if you have any concerns.
For those with lactose intolerance, Lactium® contains about 0.6% lactose, so one dose of 150 mg Lactium® per day amounts to 0.9 mg of lactose.
Caffeine reduces the release of GABA and so can decrease the effectiveness of Lactium®.

Leapfrog SNOOZE contains vitamin B6, an essential, water soluble vitamin that supports mood regulation and shows key benefits to the brain and nervous system. B6 aids in the production of melatonin, the precursor to sleep and has a key role in supporting sleep/wake cycles. We’ve chosen Pyridoxal 5-Phosphate (P5P) which is the bioactive, more absorbable form of B6 and so doesn’t need to be converted within the body.
Leapfrog SNOOZE contains some other necessary agents, which are all safe ingredients:
Xylitol – a substitute for table sugar, xylitol is regarded as a healthy alternative to traditional sweeteners that has a low glycemic index. It has antibacterial and anti-inflammatory potential and has a significant antiplaque effect on the teeth surface and can reduce gingival inflammation.

Citric Acid – this boosts the acidity, enhances the flavour, and stabilises and preserves the active ingredients in our chewable tablets.
Natural Flavourings – we’ve chosen berry flavour to give our chewable tablets a pleasant taste.
Red Beet Juice Extract – Lactium®, the primary ingredient of Leapfrog SNOOZE is cream in colour and so we added red beet juice extract to give the tablets a pale purple colour to match the natural berry taste.
Magnesium stearate – this is a lubricant which stops the formulation from sticking as its made and 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.

Leapfrog FOCUS is a supplement containing Lactium®, Lactoferrin. L-Theanine and vitamin B12. Think of the calm state of a baby after feeding…Leapfrog FOCUS is formulated to emulate that mood, promoting relaxation and calm. Lactoferrin, a protein made by our bodies daily, has neuroprotective effects and enhances learning, memory and neuroplasticity. L-Theanine and vitamin B12 promote attention, focus and clarity. Taking Leapfrog FOCUS during periods of anxiety or stress disturbance may help to calm and unwind the mind.
Adults can chew 1-2 tablets daily, and children over 12-17 years can take 1 tablet daily.
Leapfrog FOCUS is formulated to sharpen responses for those under acute stress: think before exams, presentations or high pressure events. It also helps with enhanced memory, learning and neuroplasticity. The effects are mental resilience, clarity and calm without relying on caffeine or stimulants. Consistent use helps maintain cognitive benefits.
Avoid caffeine when taking FOCUS as it can negate the effects of Lactium.

Those suffering from severe lactose intolerance may often consume 7 to 12 g of lactose per day.
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.
Lactium® contains about 0.6% lactose. One dose of 150 mg Lactium® per day – the amount in one tablet of Leapfrog SNOOZE or FOCUS – corresponds to 0.9 mg of lactose.
As milk is an allergen, do have a chat with your health practitioner if you have any concerns.
No, Leapfrog's Lactoferrin and Lactium are sourced from milk and therefore not suitable for those with a milk allergy.
Yes, all our supplements are nut free and manufactured in a nut free facility.
Yes, all Leapfrog's supplements are gluten free.
Yes, Leapfrog is suitable for vegetarians.
No, Leapfrog is not suitable for vegans. Lactoferrin and Lactium are sourced cow’s milk.
Leapfrog IMMUNE, SNOOZE, and DAILY are suitable for pregnant women. Leapfrog FOCUS is not suitable for pregnant women because of the L-Theanine content.
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 about taking Leapfrog however, do consult a physician before taking this supplement.
Yes Leapfrog IMMUNE is suitable for children from age 4. Leapfrog SNOOZE from age 7, Leapfrog FOCUS from age 12 and Leapfrog DAILY from age 12.
Lactoferrin is safe for children (and is, of course, a key component of mother’s milk), so we suggest our IMMUNE chewable tablets are suitable from age 4. Our IMMUNE 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.
Yes, Leapfrog is perfect for travelling by plane. IMMUNE and DAILY can help with immune support, SNOOZE for jet lag, and FOCUS to help you arrive mentally clear and calm. As a chewable tablet, there's no water needed, and no big pills to swallow.

Please see the blister pack or the back of the carton for the Best Before End date. Please keep Leapfrog in a cool, dry place. And unlike frogs, our chewable tablets should not get wet.
Yes, Leapfrog is suitable for those who have anaemia. 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 raises serum iron and ferritin - a natural way to up iron levels during anaemia, without side effects. It's said to also balance iron levels if you have iron overload. If you have any health issues in this area, do consult with your health practitioner first before taking this product.
Lactoferrin does not contain casein, but the Lactium in our SNOOZE and FOCUS products does contain casein.
Yes, you can take Leapfrog every day and Leapfrog DAILY has been formulated as a daily multi nutrient.
There are no contraindications in taking Lactoferrin or Lactium every day over a long period, although there is as yet no data for supplementing with it one’s whole life.
Yes, Leapfrog IMMUNE, FOCUS, DAILY and SNOOZE can be taken together.
You could take 1 x DAILY in the morning, 1 x FOCUS at lunch, 1 x SNOOZE before bed. If you needed an extra boost due to feeling vulnerable to infection, you could take 1 x IMMUNE. That gives you 550mg of Lactoferrin - and you can have up to 3.6g of Lactoferrin in a day according to official recommendations (and even then its not “unsafe” to have more).
In terms of Lactium, you can take 1x FOCUS and 1 X SNOOZE every day or increase to an extra FOCUS or SNOOZE if you need to off/on. Each tablet has 150mg Lactium and you can have 300mg per day - on occasion up to 600mg if you feel you need it.
Lactium is an ingredient of natural origin as it is sourced from milk, and is harmless. Unlike benzodiazepines, which belong to the anxiolytics family, Lactium does not create any addiction, even at a high dosage.
No, drinking milk does not make you feel sleepy. The decapeptide with the soothing properties found in Lactium® – namely alpha-casozepine – is not present by itself in milk and is encrypted in AS1- casein. It’s released in babies but not in adults. We have Lactium inside our chewable SNOOZE tablets.
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 antibiotics and are routinely checked by veterinary experts.

Leapfrog Remedies’ products are formulated by scientists and compounding pharmacists who research, trial and test ingredients for a wide range of supplements.
Yes, Leapfrog is proudly made in the UK. Leapfrog is manufactured by companies that have BRCGS ‘AA’ Food Safety Accreditation – all their products comply with UK and EU legislation.
Our Lactium and Lactoferrin are sourced from family farms in Northern France.

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.
