(Google Shopping) Kidney



— Traditional peoples, Native Americans and early ancestral healers believed that eating the organs from a healthy animal would strengthen and support the health of the corresponding organ of the individual.*  — 



For most of human history, we effortlessly consumed (nose-to-tail) the things we needed for strength, health and happiness. Like the fertile ground that we once walked upon, we were a natural extension of this earth. In the modern world, we unknowingly struggle to fulfill our nutritional needs in order to support and sustain a vibrant, disease-free life. We are now part of a world where individuals struggle with kidney health, urinary maladies and detoxification. The solution is to restore and rebuild our biological resilience with proven anthropological ways that are backed by modern science... this includes the use of kidney glandular.

There's an old Comanche narrative that has been retold for generations about a young man who loved his wife so much that when she died, he fed her the fresh kidney of a buffalo and then she came back to life.2 This tale has remained with the Comanche people to serve a greater purpose... to pass on the wisdom of feeding kidney to those who are ailing. There are many accounts of our ancestors taking an animal... the young and the warriors favored liver and heart while the ailing, frail and the old received kidney to build strength, immunity and vitality.3 

Organs and glandulars were a staple of our early ancestors' diets as the ultimate superfood, for good reason. It turns out, this nourishing tradition is backed by science... "Radioisotope labeling studies in animals have shown conclusively that, when eaten, organs and glands selectively travel to the corresponding organs and glands in high concentrations. This research, done at the University of Scotland in Edinburgh, lends credence to the ancient practice of eating animal organs to help ensure health in one’s corresponding organs..." - Dr. Ron Schmid, ND.*4 Our early ancestors knew this, which is why their traditional diets included the frequent and nourishing consumption of nose-to-tail nutrients.

Whole food, nutrient dense organs and glandulars can provide great benefit for those seeking targeted support in harmony with nature — the old fashioned way, the way that our early ancestors did.* Grassfed Kidney is a whole food and dietary supplement that provides 100% pure bovine kidney with kidney specific peptides, cofactors, enzymes and micronutrients to nourish and support one's own kidney health.*

New Zealand seems like it was made for raising healthy animals. Its location and climate produce pristine conditions for cattle and sheep, and the farmers have uncanny expertise handed down for generations. New Zealand is unique among meat-producing regions in the world because its climate is moderate so the grass in the pastures grows fresh and grows green year-round which means the cows and sheep can eat the food that’s healthiest for them every day of the year.

Our nose-to-tail product line is always from grassfed, inspected animals born and raised without the use of pesticides, hormones or antibiotics. Health of livestock used for manufacturing in New Zealand is closely monitored by a world leading biosecurity system that is second to none, and is a global exemplar. Strict government licensing, auditing and certification procedures mean that our genuine New Zealand freeze dried products can be used with complete confidence in their origin, safety and efficacy. Freeze-drying preserves the heat sensitive vitamins, minerals and co-factors of components leaving the nutrients in the same balance as found in nature.


* Our product line is 100% additive-free. Absolutely no stearates, lubricants, binders, fillers or flow agents... except with our Bone Marrow (see Other Ingredients) *

Traditional peoples, Native Americans and early ancestral healers believed that eating the organs from a healthy animal would strengthen and support the health of the corresponding organ of the individual. For instance, the traditional way of treating a person with a weak heart was to feed the person the heart of a healthy animal. Similarly, eating the kidneys of a healthy animal was believed to nourish urinary ailments, boost vitality and support overall kidney health... Pancreas was fed to people with digestive and endocrine problems... and spleen was fed to people with immune and blood deficiencies.*

Dr. Royal Lee, and other early nutritional pioneers, believed the degenerative processes of a specific organ / gland could be reversed by ingesting the corresponding raw materials specific to that organ / gland.5


Whether from grassfed beef, bison, or lamb, grass fed liver is one of the most nutrient-dense, health promoting foods you could possibly eat. Hunters all over the world, for uncounted thousands of years, would eat the raw livers of the animals they killed. Lions and other predatory animals will also eat the liver first. Grass fed liver is particularly rich in vitamin B12, vitamin A, choline, folate and and many other powerful nutrients that most people are deficient in. Grass fed liver also contains compounds that help the human liver function better. Other substances in liver reduce fatigue and improve kidney and brain function.*1

Many people look to targeted support "like heals like" while neglecting the very fundamental nourishment that governs our biology, health and well-being. It's no wonder that so many people successfully support organ and glandular related health conditions (thyroid, adrenal and kidney included) by just nourishing their bodies with Liver and Bone Marrow.*

  • Healthy Kidney Building Blocks... Kidney Specific Proteins, Peptides, Enzymes & Cofactors

  • Molecular Biodirectors — DNA Blueprints To Healthy Tissue

  • B12 & Selenium

NOTE: For intensive support, consider reviewing the life’s work of Dr. John F. Prudden... he showed that the use of bovine tracheal cartilage (BTC) had unique and powerful effects on healing, immune conditions and other life threatening conditions considered to be treatment resistant to conventional therapies.*



  • Optimal Kidney Health Based On "Like Supports Like" *

  • Urinary Health, Gout & Detoxification

  • Vitality, Energy & Thyroid Health (high in B12 and selenium)

 NOTE: The one nutrient which is most effective in preventing gout is vitamin A (think liver), because it helps protect your kidneys—healthy kidneys prevent the buildup of uric acid by excreting it in your urine. Therefore, organ meats actually protect you from gout, rather than cause it. 6



Our Grass Fed Kidney is a whole food dietary supplement that provides 100% bovine kidney. This supplement can be taken with (or) without food (even though it technically is food). The suggested use is 6 capsules a day or as directed by a healthcare professional — for added support, the dose can be doubled. If consuming more than six capsules at once, the doses should be separated by at least three hours to improve tolerability.



Most customers tolerate our supplements without incident; however, approximately 5 to 10% of customers (usually with an autoimmune condition) may experience a detoxification reaction. Detoxification reactions go by many different names including healing reactions, healing crises, cleansing reactions (or) Herxheimer reactions with hallmark symptoms of nausea, headache, lethargy, dizziness and other flu like symptoms. In this instance, detoxification reactions are generally an indication that detoxification pathways in the body are back online... cells suddenly have an opportunity to release an even greater than normal quantity of stored toxins, metabolic wastes, pathogens and unwanted material. 

A detoxification reaction is more likely to occur when starting with the full suggested serving size of 6 capsules per day. If you know that you are sensitive to supplements and/or you have an autoimmune condition, you may wish to start slow when adding this product to your current regimen. Tolerability can be greatly improved by starting with just 1 (or) 2 capsules a day and increasing by just 1 capsule every couple of days — this method may take a full two weeks to achieve the desired serving size of 6 capsules per day.

For customers that are highly sensitive to supplements and/or have an autoimmune and/or methylation SNPs, I suggest that you "play it safe" by introducing just one new capsule per week. In other words, just 1 capsule during the 1st week... 2 capsules during the 2nd week... 3 capsules during the 3rd week and so on... yes, this will take some time to reach the suggested dosages but this greatly helps to ensure tolerability of this deep nourishment so that it has a chance to do good.



Many kidney issues have either a hyperinsulinemic characteristic, an autoimmune characteristic, and or a combination of autoimmunity or hyperinsulinism. I'm not saying that all do, just most! A standard, low-ish carb paleo/primal diet can fix most of these issues. For serious kidney damage a low-protein, ketogenic diet can be remarkably therapeutic (see below).

  • Restrict protein to just what your body needs. An ideal protein intake for most is 40 to 70 grams a day (The AKF recommends a maximum of 50 grams).

  • Restrict or eliminate carbs... chronically elevated BLOOD GLUCOSE levels DO cause kidney damage.

  • Restrict or eliminate fruits and all fructose. Dietary fructose REALLY causes kidney damage.

  • Restrict liquids to pure, clean water... stop the sugar madness and drink what our early ancestors drank!

  • If you get kidney stones that are from oxalates, reduce your green veggie intake (spinach for example) and have other types of veggies.

  • If you get kidney stones that are from urate salts, you are likely NOT following a low-ish carb paleo diet, you likely have insulin resistance and your liver is not processing uric acid.

Ketosis is a high fat, moderate protein, low carbohydrate way of eating. For serious kidney damage, consider going with a higher fat, lower protein and low carbs approach. Have a look at what I eat but be careful with too much protein as this can kick you out of ketosis and add stress to your kidneys.

TYPICAL KETO — FOR ME... 75% healthy fats, 20% protein and 5% carbohydrates.

TYPICAL KETO — FOR KIDNEY RECOVERY... 85% healthy fats, 10% protein and 5% carbohydrates.



  • Wallaby Organic / Grass fed yogurt (2 cups or 150g) - for kidney recovery, adjust this down by 2/3

  • NOW Brand MCT oil (1-2 tablespoons; up to 30g- dose to tolerability). NOTE: MCT always produces elevated ketones.

  • Organic raw virgin coconut oil or organic ghee (2 to 3 tablespoons or 30 to 45g)

  • Organic almond butter (2 tablespoons or 30g)

  • Organic unrefined red palm oil (1 tablespoon or 15g)

  • Grassfed Ancestral Collagen / Gelatin (10-20g) - for kidney recovery, adjust this down by 2/3

  • Himalayan sea salt -- 1/4 tsp (2 to 3g) - for kidney recovery, adjust this down by 2/3

  • Organic cinnamon -- 2g

  • Organic instant coffee -- 2g (only when seeking variety)

  • Organic / Grassfed vanilla protein powder (1 scoop) — I like Bluebonnet Grassfed Protein for kidney recovery, adjust this down by 2/3

  • Organic banana (optional when not doing strict keto or if sleep if affected by too low carb consumption)

  • Organic / Pasture raised raw eggs (4 to 6 large eggs) - for kidney recovery, adjust this down by 2/3

  • Organic raw pastured-raised milk (1 cup or 150g)... raw is best but Whole Kalona Brand Milk is a good second option if you don't do raw milk. If you don't tolerate milk, find an alternative. - for kidney recovery, adjust this down by 2/3

This shake takes me a whopping 15 minutes to make... It's super convenient... and, it's down right delicious. If I don't make a shake, I will have a bunch of pasture-raised eggs (8 or so - for kidney recovery, adjust this down by 2/3) that are smothered in a massive amount of butter topped with crunchy sea salt, a side of avocado, nitrate-free, sugar-free bacon and a dollop of homemade sour cream. Are you kidding me... don't even try to tell me that your current breakfast is better in taste nor in health. 


  • Homemade Bone Soup (simmered for two to three days with tons of marrow)

  • Serving or Kimchi

  • Organic Avocado (optional: top with fish eggs, lemon juice and sea salt)

  • Grass fed butter or Ghee (2 tablespoons)

  • Salad of dark leafy greens (when in season) w/ 2 tablespoons of organic, fresh pressed olive oil and sea salt (I get mine from Apollo Olive Oil)

  • Grass fed organs (6 - 9 oz of various animals, various organs) - for kidney recovery, adjust this by 2/3

  • Organic almond butter (2 tablespoons) mixed with organic raw coconut oil (2 tablespoons)

  • Organic banana with raw local honey (optional: when not doing strict keto or if sleep or gut if affected by too low carb consumption)

  • 100% Cacao block for dessert

We generally carb reload on the weekends with plenty of sweet potatoes, raw local honey, the occasional sorghum and various in-season fruits. For kidney health, I don't suggest massive refeeds like we do... stay the course until you're better.

We also do a twenty-four to thirty hour fast on Sundays... it's not as bad as it sounds. We eat an early dinner as we normally would on early Saturday evening... skip our first meal on Sunday, and eat an amazing fish-based dinner (usually wild caught sardines) with the entire tribe on Sunday. Once a quarter, we do a 5-day water only fast (adults only). For kidney health, check with your doctor first... stage 3 and 4 patients may have more difficulties maintaining fluid.



  • Magnesium... transdermal magnesium oil applied to feet before bed and oral magnesium.

  • Vitamin D3 - only when not able to get adequate sun exposure

  • Vitamin K2 - only when not regularly eating my fermented veggies, sauerkraut, kimchi or natto 

  • Grass Fed Kidney

  • Grass Fed Liver

  • Grass Fed Bone Marrow

  • UVEX Glasses

  • Honorable Mentions For Targeted Support - may use Thymus or Spleen for allergies or to boost immune system... Kidney for kidney and urinary support... Brain if the brain need a boost... Bovine Tracheal Cartilage to recover an injury... Thyroid in the winter when little to no carbs are available... Adrenal if adrenal support is required... you get the picture. 

Keep in mind that my tribe and I eat a very nutrient dense diet. We consume the whole animal just as our ancestors did... That's right, we eat the liver, kidney, pancreas, spleen, heart, thymus, bones, tendons, ligaments and more... and we eat this way every day (except on vacation we take extra Liver, Beef Organs and Bone Marrow supplements). We love our bone broth (this is my wife's specialty), and we eat tons of pastured eggs. Wife is awesome enough to sprout chickpeas for us. Then, she turns half of the batch into the best homemade hummus in the world. Super high in folate (NOT SYNTHETIC FOLIC ACID, big diff)!!

You never know, ancestral eating patterns (i.e. cycling back and forth between paleo, ketosis and fasting) could easily be the missing link to the energy, mood, memory and mental performance benefits that we are all after. This is how our early ancestors ate. Start eating like this to build your biological resilience.

high quality ORGANS & GLANDS

Okay, you're convinced! You're going to start incorporating nose-to-tail nourishment in your routine because, well... you're educated now... you understand, just as our early ancestors did, that they provide superlative health benefits that are missing in our modern diets. The next step is sourcing it. It's important that you source the highest quality because not all organs, glands and cartilage are created equal. Consider the source. 

  • Should Come From An Unpolluted Geographical Region — Isolated, Healthy, Pristine Lands 

  • Should Come From Pasture Raised Animals

  • Should Come From Grass-Fed & Grass-Finished Animals

  • Should Come From Animals That Are Hormone, Pesticide & GMO Free

  • Should Also Be Ultra Pure... Absolutely No Fillers (or) Flow Agents, No Allergens

  • Should Be Non-Defatted

  • Should Be 100% Freeze Dried... Freeze Drying Preserves Heat Sensitive Biological Activity

new zealand grassfed beef liver


If you're going to pick just one ancestral supplement to start with, make it our GRASS FED BEEF LIVER... unless you need targeted support with another specific organ system (see below). If you are going to pick two supplements, our GRASS FED BEEF LIVER and our GRASS FED BEEF ORGANS provide complementary and synergistic nourishment. If you can add a third supplement, GRASS FED BONE MARROW fills fat soluble nutrition gaps, provides stem cells, bovine cartilage, glycosaminoglycans and the fat soluble activators that nutrition giant Dr. Weston Price extensively wrote about.

  • Grass Fed Beef Liver

  • Grass Fed Beef Organs (liver, heart, kidney, pancreas, spleen)

  • Grass Fed Bone Marrow

On the other hand, if you're looking for targeted organ support, you may be interested in our GRASS FED BEEF HEART to support heart health (or) our GRASS FED THYROID to support a struggling thyroid (or) our GRASS FED THYMUS to support thymus function and immune health... you get the picture.* We have a nose-to-tail product line that can be found on our "Products" page. If you can't find what you're looking for (or) you're not sure what you're looking for, send us an email and we'll do everything we can to help.



Our genome has evolved with the nourishment of nose-to-tail dining since the beginning of time. Grassfed Kidney is a whole food and dietary supplement that provides 100% pure bovine kidney containing powerful building blocks and biodirectors along with high amounts of B12 and selenium to boost energy metabolism. Based on the concept of "like supports like," grass fed kidney may nourish and support our own kidneys.*

Not all organs and glands are the same. Look for the highest quality bovine kidney... It should come from pasture-raised, grass-fed and grass-finished animals that are hormone, pesticide and GMO free. If considering a supplement, look for one that is ultra pure (without binders, fillers (or) flow agents) and look for the freeze dried variety as these have been shown to optimally preserve nutritional factors, growth factors and co-factors.

We care deeply about each and every aspect of our "seed to supplement" way of life... great love and gratitude goes out to the souls of these beautiful creatures that were sacrificed so that we could be nourished.
