Containing 250+ bioactives, colostrum is a scarce superfood shown to get to the root cause of gut issues including IBS, chronic bloating, excessive gas, irregular bowel movements, sugar cravings + much more.
The gut plays a critical role in optimal health. When the gut lining is healthy, it is a barrier of tight junctions. These junctions selectively absorb nutrients, vitamins, minerals and amino acids while keeping out allergens, bad bacteria, toxins, gliadin and viruses. However, certain lifestyle factors can damage this barrier leading to a host of downstream effects. Thousands of studies now demonstrate that the gut barrier holds the delicate balance between health and disease.
Processed foods, pesticides, sugar, alcohol, antibiotics and chronic stress damage our gut barrier, leading to leaky gut syndrome (intestinal hyper permeability). When our gut junctions become leaky, bad bacteria, allergens and toxins can leak into the blood stream resulting in immune activation and inflammation. With time, this ongoing reaction can give rise to inflammatory conditions such as IBD or more commonly, symptoms that resemble those experienced in IBS. Gas, bloating, constipation, diarrhoea, stomach cramps can all be tied back to a disrupted gut barrier. Leaky gut is the true cause of IBS.
Colostrum contains an estimated 250+ bioactives, many of which have anti-inflammatory, antimicrobial, anti-pathogen, antioxidant and immunodulatory benefits at the gut level. Some of these bioactives include Immunoglobulins, sIgA, Growth Factors, Lactoferrin, Oligosaccharides, Prebiotics, Cytokines, Proline Rich Polypeptides + much more. Colostrum also contains a host of essential vitamins and minerals which are foundational to gut health.
Multiple studies demonstrate that bovine colostrum can help reverse leaky gut. For example, just 500mg (small dose) of colostrum was shown to improve leaky gut (1). While two other studies found that colostrum improved and blunted leaky gut by 70% and 80% respectively (2)(3). We also have studies showing that colostrum led to a significant reduction in Zonulin levels, the main test for measuring intestinal permeability (4).
Overcome loose stools and recover quicker from illness. In a meta-analysis looking at 5 double blind placebo controlled studies, bovine colostrum was shown to reduce the occurrence of diarrhoea by 70% (5). Colostrum reduced stool frequency and pathogen detection in stools.
Those with IBS often have low levels of beneficial bacteria. In studies, colostrum has been shown to increase Bifidobacterium spp, Lactobacillus spp, short-chain fatty acid microorganisms and also improve the diversity and abundance of good bacteria (6)(7)(8).
sIgA is an immunoglobulin which protects our immune barriers, including the gut. Low SIgA levels are linked with food sensitivities, allergies, IBD and IBS symptoms. In one study, bovine colostrum was shown to increase s-IgA levels by 79% after 12 weeks of supplementation (9).
Gut pathogens and bad bacteria are often the main culprits behind bloating, gas and loose stools. In studies, colostrum has been shown to shift dysbiotic (unhealthy) gut environments towards eubiotic (good) gut environments (10). Studies also showed that colostrum reduced levels of e.coli, worked against H.Pylori and cleared C.difficile when paired with a probiotic (11)(12)(13).
People with IBS have elevated levels of Endotoxin, which as a metabolite produced by negative gram bacteria in the gut. It has also been connected with weight gain, inflammation and is one of the leading causes of inflammatory conditions. In multiple studies, colostrum has been shown to reduce plasma endotoxin (14)(15)(16). In one study, it reduced it by as much as 67% (17).
IBS sufferers often have irregular and damaged intestinal villi. These villi make up the tight junctions in the gut but can easily be damaged by lifestyle factors, coeliac disease and certain medications. In studies, colostrum was shown to help repair the intestinal villi aswell as repair gut damage caused by medications like NSAIDs by 30-60% (18)(19).
Colostrum is the richest source of Immunoglobulins, containing 100x more immunoglobulins compared to mature milk.
At the gut level, Immunoglobulins act as a defence system against bacteria, toxins, viruses, and other antigens. They bind, recognise and destroy these toxins thereby fortifying the gut barrier and regulating the innate and adaptive immune system.
Secretory IgA is one of the most important immune molecules which plays an essential role in ensuring the health of the gut barrier. It prevents the overgrowth of mucosal pathogens and bad bacteria.
Low SIgA levels have been found in people with IBD, IBS, food Intolerances, intestinal permeability and autoimmunity.
Colostrum has been found to help increase and modulate IgA levels. In one study, long distance runners taking bovine colostrum for 12 weeks, improved s-IgA levels by 79%.
Colostrum contains close to 50 different growth factors including IGF-1, IGF-2, TGF-β and TGF-α which are exclusive to bovine colostrum.
Growth factors are natural proteins which promote healing and repair. Many of these growth factors have been shown to display antihypertensive, antioxidant, antithrombotic, antimicrobial, anti-inflammatory and immunomodulatory activity.
Studies show that growth factors repair intestinal cells, enhance immunity, build lean muscle and enhance wound repair.
Lactoferrin in an iron binding glycoprotein which plays an important role in iron regulation and immune health.
Lactoferrin displays antioxidant, antimicrobial and immunomodulatory activity. It is effective against viruses, pathogens (like e.coli), the common cold and viral gastro-enteritis. It also reduces pathogenic microbial load.
Studies show that lactoferrin is more effective at increasing iron levels than synthetic iron tablets. It has also been shown to restore the gut mucosal barrier.
Bovine colostrum is a rich source of Prebiotic oligosacchardies.
Oligosaccahrdies are the only prebiotic shown to promote the growth of Bifidobacterium. This probiotic or species of bacteria has been shown to reduce gut permeability, inflammation and restore gut homeostasis (e.g. crowding out bad bacteria in favour of the good guys).
New evidence is also looking at the role of prebiotic oligosaccharides in obesity prevention. For example, one study showed that the consumption of oligosaccharides significantly reduced weight gain and reduced intestinal permeability.
Proline Rich Polypeptides are incredibly small chains of amino acids that have powerful effects on immunity.
They have been shown to promote T-lymphocyte function, stimulate undifferentiated lymphocytes, promote the growth of B cells, enhance natural killer cell activity, increase the proliferation of leukocytes and inhibit viruses known to be linked with autoimmune disease.
One specific Proline rich polypeptide called colostrinin has recently been shown to improve cognition and outcomes in patients with mild to moderate dementia.
Colostrum contains about 70 different enzymes with lysozymes and nucleases being the most common.
Lysozymes play a key role in innate immunity and provide protection against bacteria, viruses and fungi. They exert anti-microbial activity and improve gut health, metabolic markers and act as a natural antibiotic against bad bacteria.
a-Lactalbumin is a whey protein that plays an important role in maintianing muscle mass and aiding in weight loss.
It has been shown to improve sleep, protect against gut infections and support an overall healthy microbiome.
Our colostrum is sourced from a unique set of pastures located on New Zealand's South Island. These pastures are surrounded by the Southern Alps with lands so picturesque they could feature on a postcard. Cattle roam the lands freely and are grass-fed and 365 day pasture raised.
Proprietary low thermal processing is used on our colostrum at temperatures much lower than industry norms. This ensures that colostrum maintains its bioactive compounds.
20% IgG is the hallmark of high quality colostrum as it is the most concentrated bioactive. Our colostrum is exclusively selected from batches exceeding 20% IgG+.
Low thermal processing maintains IgG activity. Higher temperature processing can denature IgG and impact the reliability of the commonly used affinity HPLC testing method. This means that 20% IgG may be closer to 15% if low thermal processing is not used.
We provide comprehensive testing for microbiologics, IgG, IgA and IgM. We are also one of the rare companies who test IGF-I, IGF-II, TGF-β1, TGF-β2 as-well as test for complete vitamin and mineral counts.
Colostrum is a scarce resource and is only collected during the cattles natural calving season. Only surplus colostrum is collected. This ensures the calf gets all the colostrum it needs to develop and be healthy with the remainder then being collected.
In order to meet yearly demand, colostrum is sourced from multiple different New Zealand farms across the South Island. It is then processed within 48 hours to maintain Colostrums Bioactives.
Avoid colostrum or milk products which come from factory farmed dairy where cows may get artificially inseminated leading to inhumane collection of milk and colostrum.
As everyone is different, there is some individual difference in how quickly someone will see benefits. For some, they will experience benefits right away. For others, it might take a few weeks to a couple of months of consistent use to start to see more transformational benefits.
In saying that, the most commonly reported benefits pretty quickly including better bowel movements, less bloating, less gas, better athletic performance and just overall feel healthier.
Just like whey protein but better. The taste is neutral so can be added to water, smoothies, shakes or any drink with ease. Some people dry scoop it because they love it so much.
Absolutely, you are pairing the No 1 most vitamin and mineral rich whole-food (beef liver) with the most bioactive rich whole-food in colostrum. Amazing to take separately but also the ultimate combination when taken together.
Yes! Our colostrum powder is sourced from Grass-fed and pastured raised New Zealand dairy cows only. We source our colostrum from a unique part of New Zealand where pastures are surrounded by the Southern Alps. It is a one of kind source of Colostrum.
Yes, our colostrum uses low thermal processing technology to ensure more active IgG. Compared to one of the main US colostrum suppliers, our colostrum contained more active IgG.
Different colostrum serving sizes have different benefits. 3g is a good place to start. Our serving size of 3g is informed by research to suit most health outcomes. Just 500mg has been shown to improve intestinal permeability while 3g has been shown in other studies to help with athletic performance, URTIs and other health concerns.
Colostrum should not be taken in capsules in our opinion. The power tastes good and has oral mucosal benefits when consumed in this way. Capsules remove this additional benefit.
Each serve of Colostrum does contain a small amount of lactose, so would not be advisable to those with severe lactose allergy.
However, many with a small dairy sensitivity find they don't have an issue with colostrum. This might come down to colostrum helping with their gut, which may be contributing to the dairy sensitivity in the first place.
If you are unsure if its right for you, always contact a health care professional before taking.
We recommend consulting with your health care professional if you are unsure about taking colostrum during pregnancy or while breastfeeding.
Amazing! I have had 2 yrs of stomach issues after having my Gallbladder removed. Within three days it had fixed any issues an I could drink coffee again and go out and have meals at a restaurant without having and emergency toilet dash afterwards. Truely wished I’d tried it sooner.
Meg
Gut issues have disappeared. Mood is up & stools are better than ever?
This product is a game changer for gut
issues, and it tastes amazing with sweet coconut water. I highly recommend it!
I have had significant gut issues where nothing has seemed to help. I’ve taken this product for a month so far and I would say I’ve seen progress. I’m keen to keep trying it and hopefully see further progress!
I started to notice a difference to my gut problems 2 days in from first using this colostrum.
I thought it was too good to be true and just coincidence but its continued to be of some help one month in.
Will definitely keep using this product and have already purchased some more while in stock.
Thank you Nahla Earth
