You may have heard the saying, “When the people lead, the leaders will follow.” Never has that saying been more true than when applied to our medical system. Over the last twenty years or so, as people have grown increasingly sick and tired of the treat-but-don’t-cure and cut-burn-and-poison models of cancer care, they are gradually forcing the conventional medical system to change. People have been taking health care into their own hands, supported by natural health practitioners fighting for the right to use safer healing approaches. In short, a paradigm shift is afoot.
Consumers have flocked to modalities such as chiropractic, acupuncture and energy healing, and to natural substances such as bone broth and raw milk, because they are good medicine. These approaches work noninvasively, have no side effects, and are much more affordable than conventional procedures. Underpinning this paradigm shift is the understanding that instead of using pharmaceutical medicine to attack and kill “invaders” in the body, the focus should be on boosting the immune system to allow the body to do what it already knows how to do—heal itself.
Conventional medicine has begun to grasp the role of a healthy gut as the basis of a healthy immune system and good health in general. It is rare to find a person with a health condition who does not have an underlying digestive issue. Even allopathic doctors are prescribing probiotics for their patients, acknowledging the massive importance of beneficial bacteria on health.1 People are also fighting dreaded diseases very effectively with stellar gut-healing nutrition.
GcMAF
Relatively new on the scene, GcMAF has been gaining attention as a tool to boost the body’s immune function while strengthening digestive health. What is GcMAF, and why is it important? GcMAF stands for Gc protein-derived macrophage activating factor. Normal Gc protein, also called vitamin D binding protein (VDBP), is an abundant glycoprotein found in human blood serum as well as in other body fluids and organs.2 Among its key functions, VDBP binds and transports vitamin D and its metabolites.2 The body uses vitamin D in almost three thousand genes, many of which play a crucial role in immune system function.3
When Gc protein converts to its active form—GcMAF—it becomes a signaling protein that instructs the body’s “garbage collectors”—cells called macrophages—to turn on. The macrophages then hunt for and consume foreign viruses, bacteria and damaged tissues. The macrophages are critical to a healthy immune system.
Ordinarily, Gc protein converts to GcMAF with the help of two types of immune system cells—B cells (white blood cells generated in the bone marrow) and T cells (white blood cells produced in the thymus gland). However, researchers have found that certain viruses cause secretion of an enzyme known as alpha-N-acetylgalactosaminidase (also called nagalase) that completely blocks conversion of Gc protein to GcMAF, preventing the macrophages from doing their clean-up job. With deactivation of the macrophages by nagalase, the body becomes toxic, and the crippled immune system cannot manage. This disengagement of the immune system can leave individuals open to infections of all kinds.
Scientists who study GcMAF strongly suspect that in addition to viruses other aspects of modern life such as stress and toxins may be contributing to high nagalase levels in the bloodstream, thereby weakening the immune system on a wide scale. Some doctors have found excessive levels of nagalase in patients following vaccination, prompting speculation that the viral antigens in vaccines may be triggering release of nagalase.
NAGALASE AND CANCER
Dr. Nobuto Yamamoto discovered GcMAF in 1980 as a professor of microbiology and immunology at Hahnemann University School of Medicine while carrying out immunological research to understand the mechanism of macrophage activation. In 1990, Dr. Yamamoto became a biochemistry research professor at Temple University Medical School, where he studied the tumoricidal capacity of macrophages activated by GcMAF and considered GcMAF’s potential as a cancer therapy.
In 1994, Yamamoto established and the Socrates Institute for Therapeutic Immunology, continuing to study the therapeutic efficacy of GcMAF for cancer as well as for HIV. Since that time, a number of studies have produced results indicating that GcMAF holds promise as an immunotherapy and anticancer agent.4
Nagalase builds up in cancer patients, and its activity “correlates with tumor burden, aggressiveness and clinical disease progression.”5 In fact, investigators have proposed assays of serum nagalase activity as a non-invasive way to evaluate the clinical severity of different cancers.6 In clinical studies involving dozens or hundreds of advanced cancer patients,5 breast cancer patients7 and other cancer patients,8 regular injections of exogenous GcMAF have led to decreased nagalase activity and clinical improvements—without side effects.
GcMAF YOGURT
In the United States, the financial and lobbying power of the pharmaceutical industry has ensured a “lockdown mentality” against many natural treatments, including GcMAF. Thus, persons interested in building up their immune system with GcMAF injections such as those used in various clinical studies might have to travel to Europe at their own expense to obtain these injections.
There is another option, however. In a new twist on old-fashioned yogurt, it is possible to make perfect “top shelf” GcMAF at home without breaking the bank. The supercharged yogurt or kefir (which one should preferably make with raw milk) includes colostrum, several dozen strains of probiotics and either yogurt or kefir culture.
Online companies offer expensive kits9 containing probiotics and cultures (typically costing several hundred dollars or more), as well as recipes and other resources. However the cheapest and most straightforward route is to bypass the kits, obtain the four basic ingredients and make GcMAF at home with good-quality raw milk.
CONSUMING GcMAF YOGURT
For the Gc protein to bind with vitamin D to create GcMAF and activate the macrophage system in the body, it is important to consume a few other nutrients with the yogurt. This will help ensure optimal results. Eat one-half cup of the yogurt first thing in the morning and just before bed.
GcMAF yogurt needs an adequate amount of vitamin D to really “turn on.” Many proponents of GcMAF are recommending doses of D3, anywhere from 2,000-10,000 IU per day. However, vitamin D3 taken on its own can be problematic. Better to take a natural cod liver oil, containing a full range of vitamin D isomers, to provide about 2,000 IU vitamin D daily, along with supporting vitamin A. In addition, eat plenty of pasture-raised egg yolks and spend as much time as you can in the sun. Vitamins A and D require support from vitamin K2 as found in foods like aged cheese, poultry liver and animal fats.
Oleic acid also is crucial for full activation. This can come from one teaspoon of olive oil, avocado oil or high-oleic flax oil.
Finally, amino acids seem to be important for reaping the full benefits of GcMAF yogurt. From my perspective, there is no better protein for supplying amino acids than egg yolks. I combine 1/2 to 1 cup of the GcMAF yogurt, one egg yolk and one teaspoon of high-oleic flax oil in a blender, morning and night. I drink this slightly sour mixture while taking vitamin D. To turn the mixture into more of a super smoothie, add some coconut water, trace minerals and a banana.
MAGIC YOGURT
For those of us who have known about and consumed raw milk for a long time, making “supercharged” GcMAF yogurt is an easy way to power up the immune system. When using raw milk, it goes without saying that it should come from a trustworthy source and be of the highest quality. I make and consume magic GcMAF yogurt from raw milk daily and know first-hand how fresh and good it can be!
SIDEBARS
GcMAF YOGURT: FOUR INGREDIENTS
• COLOSTRUM: Many brands are available. Select a lab-quality colostrum that is GMO-free, such as colostrum from New Zealand.
• PROBIOTIC POWDER: Many brands are available, but I recommend the Garden of Life raw probiotic powder, which contains thirty-four probiotic strains and 400 billion CFU (colony forming units). It is hard to find another probiotic powder that packs this much punch.
• YOGURT STARTER CULTURE: Cultures for Health and other similar entities have a variety of yogurt starter cultures available. Because the colostrum and added probiotics already add a lot of flavor, it is preferable to select a yogurt starter culture that has a mild flavor. (Note: If using kefir instead of yogurt, there is no need to keep purchasing yogurt starter culture—see the sidebar on page 39 for insructions giving more details about using kefir.)
• RAW MILK: Using raw milk is very important. The foremost labs and scientists working on GcMAF in Europe report that raw, organic milk produces the strongest results. Fortunately, it is not as difficult to find raw milk in the U.S. as it used to be. The Weston A. Price Foundation’s website realmilk.com is an excellent guide to local sources of raw milk. Also check with the Local Chapter volunteer in your area for a list of raw milk and other food sources (see page 94). When ordering supplies, and particularly the probiotic, it is worth spending extra money for overnight shipping so that the probiotics do not sit out in the heat. Although most companies ship probiotics with an ice pack, the ice pack will last at most for two days. It makes sense to protect this investment. The probiotic and the yogurt starter should go into the refrigerator as soon as they arrive. Powdered colostrum is very stable but does best in a cool, dark place.
INSTRUCTIONS FOR MAKING GcMAF YOGURT
1. Let one quart of raw milk sit out in a glass jar with the lid on until it roughly comes to room temperature. Leave about two inches of space at the top to allow for expansion during fermentation.
2. Put 1 tablespoon of colostrum and 1 teaspoon of probiotic powder into a pan with 1/2 cup of milk. Lightly warm and whisk the mixture until smooth. The minor heating helps eliminate lumps. (Mixing without heating may be preferable, but it is difficult to get rid of the lumps without slight heating.)
3. Once the mixture is creamy, pour it into the jar with the remainder of the raw, room-temperature milk and stir thoroughly.
4. Sprinkle the yogurt starter over the top of the milk-colostrum-probiotic mixture. In warmer rooms or climates, simply let the yogurt starter sit on top rather than stirring it in. (This is because the colostrum and extra probiotics already give the mixture so much “octane” that stirring in the starter tends to prompt overly rapid fermentation.) In cooler rooms or climates, it may work better to mix the starter into the mixture.
5. If mixing the ingredients at night, the mixture typically will achieve a creamy yogurt-like consistency by morning. To retain this texture, refrigerate the jar right away. Otherwise, it will continue to ferment into more of a cheese-like texture. The latter does not pose a problem for consumption, but a creamy consistency generally tastes much nicer.
6. It is also possible to use live kefir instead of yogurt starter. When combining the initial ingredients, substitute 2-3 tablespoons of freshly made kefir (but not the kefir “grains”) in lieu of the yogurt starter.
7. Although the proportions of colostrum, probiotic and starter included in the recipe are intended for one quart of raw milk, I have found that holding those proportions steady while using twice as much milk (one-half gallon) still produces a very effective yogurt. Individuals with critical health issues should probably stick with the more concentrated one-quart recipe, but those who are consuming the yogurt simply to support digestive health and the immune system can use one half-gallon of milk, cutting the other ingredient costs in half.

Dear WAP researchers,
This is fantastic. I love the recipes and direct advice provided. This is literally a recipe for health.
Farmers over Pharmacies is the clear direction going forward in sustainable medicine. Watch this video about Tara and her Crohns. She avoided a colostomy bag by using Raw Milk Kefir!! https://www.youtube.com/watch?v=KDRnNxnj1AU
She now leads a very normal life!
Constance says
Thank you so much for publishing this article!! The week after reading it in the journal I ordered a probiotic and colostrum. Since raw milk, homemade yogurt and kefir are staples in my kitchen, this is a snap for me to whip up. I add Celtic sea salt, bananas or frozen berries to the smoothie. My beautiful babies (ages 1 and 3) gulp it down along with their cod liver oil. I have high hopes it will keep us healthy all through our winter travels!
Constance says
Sea salt *and* bananas or berries
Niti Shah says
Thank you, WAP! Great articles always!
I wanted to connect with Lee Emerson. Does he provide coaching or one on one consultation?
Please let me know,
L says
After you add the yogurt starter do you cover the jar by sealing tightly Or loosely. Or place cloth over it??. I have plastic caps for my mason jars.
and do you then place in dark dry place or where? I will do this at night.
You did not finish writing about this final process …
THANK YOU & Many blessings!
Kerri says
Can you use raw goat milk?
April says
Thank you for the great article. I have been contemplating doing the GCMaf yogurt for quite some time, but the kits are so expensive that I find myself unable to pull the trigger.
My question is: Would raw goat milk be a viable option in place of raw cow milk?
Joe says
Goat and especially camel milk are considered superior to general cow milk. All raw organic, of course. Cow milk is good to go, assuming the cows are top grade.
Amriki says
Camel milk works well, making my second batch now. Used sheep yogurt instead of starter culture (2 or 3 tbsp) along with probiotics I had on hand, and powdered colostrum.
Blended everything when the milk was still warm from collection. Strong taste, this yogurt! Next morning it was ready, creamy consistency. This time its taking longer, a kittle cooler and doubled the milk so Ill give it a few more hours inshallah (God willing)
Also made a probiotic enema by diluting with warm water 1:1 to total 1 liter.
Quick way to a belly full of good bugs!
I’ve also used coffee to dilute (like Gerson but for the probiotic bit) but not yet with this GcMAF camel milk blend.
Effects after probiotic enema are sometimes pleasantly dramatic, going from feeling unwell to feeling energetic after a single treatment.
As always, YMMV.
Gitte says
To my knowledge, milk kefir grains have about 32 probiotic strains. The powder used above has 34 probiotic strains. Logic question to me is, why not use some more kefir milk when making the GCMaf yoghurt, which is ‘free’ when one makes kefir every day, instead of the powder? . . while still adding plain yoghurt to get the right consistency. Would this not be just as good?
Dave Clark says
I use kefir instead of yogurt, for the reasons you mentioned, and because it lasts longer in the fridge as well. I use the colostrum, Garden of Life probiotic powder, and kefir made from local raw milk. I don’t add vitamin D, as I get mine from a vitamin D lamp, but I do use a vitamin K1 and 2 product. If you look on you tube there are people using the kefir to make the GcMAF kefir, instead of yogurt.
zain says
Not exactly vegan friendly this.
Eileen says
Question. Why not add the ingredients to raw grass fed organic plain Kefir, let sit in refrigerator, then drink this. Would this have the same benefits as the GCMaf?
Brandon LaGreca says
I believe it is a bit presumptuous at this point to suggest that fermented dairy products contain GcMAF (though I hope they do). Of the companies selling these strains to make GcMAF, none provide independent analysis of a finished dairy culture to confirm the presence of this compound. You can read a review of the science on a blog post I wrote on the subject here: https://www.easttroyacupuncture.com/gcmaf/
Bob says
What else reduces nagalase levels other than GcMAF?
Alaister Copland says
It’s quite possible that CBD oil and mistletoe extract work in much the same way as GcMAF kefir, but these are both very expensive and can’t easily be made at home, as with kefir.
Sally Oh says
Hi Brandon, on my Functional Health Practitioner’s forum, some colleagues pointed out that “any” probiotic won’t work to make the GcMAF. You need the specific probiotic they use in the kits…. Is this true, do you know?
Aaron says
Can the GcMAF even pass through the stomach acid intact when taken orally?
Sean says
Can I use water kefir to save the cost of and the difficulty of finding the milk?
Maureen Diaz says
No, you absolutely will not get the same results as with raw milk. The raw milk contains many important nutrients which aid tremendously to the success of this, not the least of which are the fatty acids which are need to feed the probiotic strains, along with the proper ratio of the fat-soluble vitamins A & D.
Sally Oh says
Hi Maureen, I just replied to Brandon about the probiotic. On my Functional Health Practitioner’s forum, some colleagues pointed out that “any” probiotic won’t work to make the GcMAF. You need the specific probiotic they use in the kits…. Is this true, do you know?
Also, Garden of Life is now owned by Nestle…
And how would you test to see if your yogurt actually contained GcMAF?
Inquiring minds, lol. It’s exhausting!!!
Carol says
I just made this last night.. it did not set-up. I will drink (not eat) this anyway. But is it still working if the yoghurt didn’t really ‘take’? Should I add some already made yoghurt to try to get it to set? Thanks!
carol s says
Hello – I cannot get this mixture to set up! I tried it with dry yoghurt starter and then with actual yoghurt and neither would set. Any ideas on getting this set like yoghurt does? Does the picture work if it has not set up? HELP!
carol s says
Not ‘picture’! – mixture. spell-check from hell….
Vicki says
How much yogurt starter do u use the whole packet, half, just enough to cover? And then do u put a lid on?
Carol s says
Hi Vicki – I used whole packet, mixed it in with the other ingredients. Put lid on. I used a warm oven once to start it and also without any added heat… neither thing worked. Any advice is appreciated!
Laura Ryan-Isaacson says
Hey Carol, I just made this and couldn’t get the yogurt to set either.
I used a 5g packet of yogurt starter and left it out since my apartment is warm.
Any luck with yours?
Best, Laura
Tracee Gluhaich says
I have a casein sensitivity. Is it possible to make without cow’s milk? OR what do you recommend? Thank you!
michael says
i live in Canada and raw milk is virtually impossible to find in Canada, if I had wheels I’d drive across the border and pick some up in Wa state..but i’s not an opti0n. Can you suggest a substitute/alternative for raw milk? All milk in Canada is pasteurized(neutered :-)) I can purchase organic whole milk pasteurized. I was also thinking maybe camel milk…I can get powdered camel milk from the US,it’s very expensive and I’m on a tiny pension. FYI I am dealing with CLL. I read coconut milk is not an option.
Mike says
In reference to instruction step 4 above -“Sprinkle the yogurt starter over the top of the milk-colostrum-probiotic mixture”, can GcMAF yoghurt from a previous batch be used as the yoghurt starter without dialling down the benefits (over time)?
Sally says
Does plain colostrum contain GcMAF?
Sally Oh says
It is almost impossible to get a raw milk yogurt to set without either adding gelatin to thicken it or boiling to break the proteins. Breaking the proteins allows it to set. I make 2 kinds of yogurt: drinkable and regular. The drinkable is still raw, no boiling. I use that for my protein/fat shakes. The regular is nice and thick for everything else.
For the GcMAF yogurt, it does not need to set, it can be the drinkable.
Here’s how I do both:
Drinkable: https://vitalityhealthworks.com/really-raw-milk-yogurt/
Regular: https://vitalityhealthworks.com/homemade-simple-instant-pot-yogurt/
Ammar says
Are you not heating the raw milk at all? I thought we need to boil it. I would love to use it raw but just want to make sure.
Graham Smith says
Old thread but still relevant.
Anyone have experience of using the kefir mix or yoghurt as an enema rather than orally? Found one article but nothing else and no references.
Ta. Graham
Marge says
Can any one recommend how to make yogurt with real raw milk without loosing the good ingredients from the raw milk? Can I use an instantpot?
Thank you.
Kelly Santillo says
Garden of Life company is owned by Nestle! DO NOT SUPPORT this unscrupulous corporation.

Bob G. says
If you use store bought Raw Milk Kefir, using 8 oz. of kefir, can you stir in a tsp of colostrum and 1/4 tsp of probiotics will this create the correct precursors for GcMaf production?
Mary W. says
I would like to know the answer to this too. Can you stir in colostrum and probiotics to store-bought raw milk kefir?
