The 7 Best Organ Meat Supplements That Are 100% Grass-Fed

If you are looking for the best organ meat supplements, a big kudos to you. This means you already understand how much nutrition and health can come from eating organ meats. They are an indispensable part of my health routine — and I will explain exactly why throughout this post.

The benefits of organ meat supplements are truly endless. Organ meats supply vitamins, minerals, enzymes, nutrient cofactors, and antioxidants that are simply unmatched by any plant food or synthetic supplement. As a registered dietitian with over 25 years of clinical experience, I have seen firsthand what these nutrients do for energy, hormonal health, immunity, and vitality.

Organ meats — also known as offal — are traditionally used in a “like-treats-like” approach: heart tissue supports the heart, kidney supports the kidneys, and so on. And there is real science behind it. Beef heart is the richest known food source of coenzyme Q10, and it is also rich in organ-specific biomolecular cofactors including mRNA and DNA building blocks.

Best Organ Meat Supplement Criteria

To find the best organ meat supplement capsules, look for the following quality standards. I’ll break down each brand so you can get the best product for your money. Desiccated organ meats simply means they are dried and powdered — a traditional preservation method used for centuries.

Best Overall: Quick Comparison

All six top brands below are comparable in quality but differ in organ ratios, serving count, and unique features.

⭐ My #1 Daily Pick: MK Supplements Grass-Fed Beef Organs

⭐ MY PERSONAL DAILY SUPPLEMENT

MK Supplements Grass-Fed Beef Organs

$59

15% off with code THEHEALTHYRD

Out of every grass-fed organ supplement I have personally tried and researched, MK Supplements is the one I take every single day — and the one I recommend first to clients, readers, and family. Here is exactly why it stands apart.

Why I Choose MK Supplements Over Every Other Brand

1

Nature-matched organ ratios. Most blends use equal amounts of each organ regardless of how they are actually proportioned in a whole animal. MK Supplements mirrors what you would find in nature — giving you far more of the most nutrient-dense organ, the liver.

2

Glass bottle — no plastic exposure. Nearly every competitor ships in plastic. MK Supplements uses glass, eliminating plastic leaching from a supplement designed to support detoxification pathways.

3

Rigorous third-party heavy metal testing. Organs can bioaccumulate toxins, which is why independent testing matters. Every batch is tested by third-party labs for heavy metals and contaminants.

4

100% New Zealand pasture-raised. New Zealand’s strict agricultural standards produce organ meats that are 50–450% richer in vitamins than conventional US beef organs (USDA data).

5

45 servings per bottle. That is 50% more servings than most competitors at the same price — making it the most cost-effective option after applying the discount code.

6

My results. I noticed improved energy, better mood, and meaningful relief from menstrual fatigue within weeks. Even my elderly dog — who also takes this — became noticeably sprier, ruling out any placebo effect.

Heart & Soil Beef Organs

$57

180 capsules (30-day supply)

Their Beef Organs formula blends grass-fed, grass-finished New Zealand liver, heart, kidney, pancreas, and spleen, and is one of the only blends on this list to add L-carnitine — an amino acid compound that supports energy metabolism and fat utilization beyond what the organs naturally provide. Each batch is tested through Informed Sport, the certification program used for elite athlete supplement safety, screening for over 200 prohibited substances as well as heavy metals, pesticides, and microbes. This would rank higher on my list if not for the price — it’s the most expensive option per serving here.

• Informed Sport certified — batch-tested for 200+ substances plus heavy metals and microbes

Other Organ Meat Supplements Worth Trying

Liver supplements are particularly valuable for women of childbearing age, who often need more vitamin A and iron than diet alone provides.

Didn’t Make the Cut

• ✗
  Salt Wrap Organ Therapy — contains fillers that compromise purity standards
• ✗
  Peak Performance Organ Meats — heat-processed, which destroys key enzymes, peptides, and heat-sensitive vitamins
• ✗
  Herbage Farmstead — contains additives not acceptable for a premium organ supplement

Organ Meat Benefits + Nutrient Breakdown

Organ meats are experiencing a renaissance — and rightly so. For generations they were a dietary cornerstone. Modern diets have largely abandoned them, and many health challenges that show up in clinical practice reflect exactly the nutrient gaps organ meats historically filled. Learn more about the broader benefits of grass-fed beef at The Healthy RD.

Key Vitamins in Organ Meats

Key Minerals & Cofactors

Organ meats are exceptional sources of heme iron, selenium, zinc, and chromium. Beyond minerals, they provide coenzyme Q10, choline for brain and memory, omega-3 fatty acids, hyaluronic acid for joints and skin, and glutathione and CLA. You can also read about how these nutrients support mitochondrial energy at The Healthy RD.

What Customers Are Saying

Organ meat supplements consistently receive some of the highest praise of any supplement category. Reviewers report life-changing improvements in energy, stress resilience, immune function, tissue strength, anemia, skin health, lung health, stamina, mood, and symptoms of conditions like Ehlers-Danlos syndrome.

My Personal Story: Why I Use MK Supplements Every Day

Gene Variants That Point Me Toward Organ Meats

If you want to explore your own genetic nutrient vulnerabilities, I recommend Dr. Rhonda Patrick’s Found My Fitness Genetic Reports, which works with raw data from 23andMe. Here are mine:

Many people share one or more of these variants without knowing it — meaning they are nutrient-deficient despite eating what appears to be a healthy diet.

Where to Buy Fresh Organ Meats & How to Prepare Them

Grass-fed organ supplements are convenient, but fresh organ meats are always an option. Ask your local butcher — you can often find excellent deals on liver, heart, kidney, and spleen from grass-fed animals. Farmers markets and regenerative farms are another great source. Learn more about what to look for in nutrient-dense animal foods at The Healthy RD.

If you are new to cooking organ meats, Dr. Kiltz offers 8 organ meat recipes including bone marrow, beef heart steak, beef tongue taco salad, and liver and onion meatballs. I also include beef organ meat recipes in my book Period Fix.

Potential Side Effects & Safety

Grass-fed beef organ supplements are generally safe for most people. Keep the following in mind:

• If you have iron overload or hemochromatosis, avoid these supplements — they are high in heme iron.
• People with gout are often advised to limit organ meats due to purine content, though some research challenges the purine-gout link.
• Always consult a qualified healthcare provider before adding new supplements. A functional medicine registered dietitian is a good starting point.
