You've probably seen them. Those dark brown capsules or jars of desiccated liver powder being lugged around by guys who look like they spend ten hours a week in a squat rack. It’s part of a massive "ancestral" movement that promises better energy, thicker hair, and a sharper brain by eating the parts of the cow most people would rather avoid. But is it just expensive marketing for ground-up scraps? Honestly, the beef organ supplements pros and cons are a lot more nuanced than what you’ll see in a 30-second TikTok.
Most of us grew up eating muscle meat. Steaks. Burgers. Chicken breasts. We ignored the stuff that actually keeps the animal alive—the heart, the liver, the kidneys. The reality is that our ancestors didn't have that luxury. They ate "nose-to-tail" because food was scarce and they intuitively knew that's where the nutrients were hiding. Now, we’re trying to bottle that intuition.
Why Everyone Is Obsessed With Liver (The Pros)
If you look at a nutritional label for liver, it’s kinda shocking. It’s basically nature’s multivitamin. While a piece of kale is great, a 100g serving of beef liver contains massive amounts of Vitamin A, B12, and copper.
Bioavailability is the big word here. Your body likes animal-sourced nutrients. When you take a synthetic multivitamin, your body often struggles to absorb those isolated chemical compounds. But with organ meat, the nutrients are wrapped in the proteins and fats your body already knows how to process. For example, the iron in beef organs is "heme iron." It’s absorbed much more efficiently than the "non-heme" iron you find in spinach or lentils. If you’ve ever felt like your energy is dragging despite eating "healthy," a lack of bioavailable B12 and iron might be the culprit.
Then there’s the heart. Beef heart is one of the best sources of Coenzyme Q10 (CoQ10). Your mitochondria—the little battery packs in your cells—need CoQ10 to function. People taking statins or those worried about heart health often supplement with it, but getting it from the actual organ of an animal is arguably more "whole food" than a lab-made pill.
I’ve talked to people who swear their skin cleared up or their "brain fog" lifted after a few weeks of consistent use. Is that anecdotal? Partly. But the density of Vitamin A (retinol) in liver is legendary for skin health. It’s the same stuff they put in expensive face creams, just coming from the inside out.

The Reality Check: Beef Organ Supplements Pros and Cons
It isn't all sunshine and "optimized" hormones. There are real risks.
One of the biggest concerns with beef organ supplements pros and cons is Vitamin A toxicity. Because Vitamin A is fat-soluble, your body stores it rather than peeing it out like Vitamin C. If you’re taking a high-dose supplement and eating liver, you can actually overdo it. Hypervitaminosis A is a real thing. It can lead to blurry vision, bone pain, and even liver damage. You have to be smart about the dosage. It’s not a "more is better" situation.
Another factor is the source. You are what you eat, and you are what the cow ate. Organs, especially the liver and kidneys, are the filtration systems of the body. While they don't "store" toxins—they process them—a cow raised in a factory farm environment, pumped with hormones and antibiotics, isn't going to have the same nutrient profile as a grass-fed, grass-finished animal.
Cost is also a massive "con." Let’s be real: these things are expensive. You might pay $40 to $60 for a month's supply of capsules. Meanwhile, you could go to a local butcher and buy a pound of actual beef liver for about five bucks. You’re essentially paying a 1000% markup for the convenience of not having to taste it.
The "Like-Supports-Like" Theory
There’s this idea in the supplement world called "Glandular Therapy." The theory is that consuming the heart helps your heart, and consuming the kidney helps your kidneys.

Scientifically? It’s a bit of a stretch.
Your stomach acid breaks down proteins into amino acids regardless of where they came from. Your body doesn't see a "heart protein" and immediately send it to your left ventricle. However, it’s true that specific organs contain the specific co-factors and enzymes needed for those functions. The kidney is high in DAO (diamine oxidase), an enzyme that helps break down histamine. If you have histamine intolerance, taking a kidney supplement might actually help your body process high-histamine foods. That’s a very specific use case that goes beyond just "getting your vitamins."
What Most People Get Wrong About Quality
If the label doesn't say "Grass-Fed" and "Undefatted," put it back.
"Undefatted" means the fat-soluble vitamins haven't been stripped away during processing. Many cheap brands use heat-processing which kills the very enzymes you’re paying for. You want "freeze-dried" or "desiccated" at low temperatures. Brands like Ancestral Supplements or Heart & Soil have built entire empires on this distinction. They use New Zealand or Australian cattle because those countries have stricter regulations on how animals are raised and treated.
How to Actually Use This Information
Don't just jump into a full dose. If you’ve never had organ meats, your digestive system might rebel. Start with one or two capsules. See how your stomach feels.

Check your bloodwork. If your iron levels are already high, you probably shouldn't be taking a liver supplement. Hemochromatosis is a condition where people store too much iron, and adding a beef organ supplement to that could be dangerous.
Actionable Steps for Beginners:
- Audit your current diet. If you’re already eating red meat 5 days a week, you might only need a small "top-off" of organs.
- Pick a "Blend" first. Instead of just straight liver, look for a "Grass-Fed Beef Organs" mix that contains heart, liver, kidney, spleen, and pancreas. It provides a wider spectrum of nutrients.
- Track your energy and skin. Give it 30 days. If you don't feel a difference, the "con" of the price tag probably outweighs the "pro" of the nutrients.
- Verify the source. Look for third-party testing for heavy metals. Since these are concentrated products, you want to ensure you aren't getting a concentrated dose of lead or mercury.
At the end of the day, these supplements are a tool. They aren't a magic pill that replaces a bad lifestyle. If you're sleeping four hours a night and living on processed sugar, a liver capsule isn't going to save you. But if you’re looking for that last 5% of nutritional optimization and you can't stomach the taste of actual organs, they’re a solid, albeit pricey, option to bridge the gap between modern convenience and ancient nutrition.
Stay mindful of the dosage. Watch your iron levels. Don't fall for the "superfood" marketing without checking the sourcing. If you do that, you're ahead of 90% of the people buying these jars.
Final Considerations for Your Routine
If you decide to move forward, integrate the supplements with a meal that contains some fat to help with the absorption of Vitamin A, D, E, and K. Taking them on an empty stomach with just water is a common mistake that leads to "nausea" and wasted nutrients. Consistency matters more than the specific brand, provided the sourcing is clean.
