Beef Liver is one of the richest natural sources of Vitamin A, B12 and folate — nutrients that are critical for energy metabolism, red blood cell production and detoxification. It also provides copper, choline, and CoQ10 to support brain health, focus and overall vitality.
Packed with bioavailable Vitamin A, B12 and folate, Beef Liver supports steady energy, blood health, and natural detoxification.
For centuries, liver has been prized as the most nutrient-dense food on earth. Our ancestors consumed it first when harvesting an animal, knowing it provided unmatched levels of Vitamin A, B12 and folate for energy, blood health and resilience. In short, it's nature's original superfood — dense with bioavailable nutrients that our modern diets often lack.
Our supplement delivers the benefits of beef liver in a convenient form, without the taste or hassle of preparing fresh liver.
We prioritize purity and potency with rigorous third-party lab testing at every stage of production. Transparency matters, so we make our test results available in our help center. You can learn more about our five-stage testing process in this blog article.
Our supplements come in amber glass bottles with metal lids (never plastic). Dark glass helps preserve nutrient integrity by protecting against light and oxygen, while eliminating the risk of microplastic leaching. It’s safer for you, better for the environment and fully recyclable — giving you peace of mind with every bottle.
100% pure, additive-free, and sourced from grass-fed and grass-finished U.S. cattle. No hormones, antibiotics, pesticides or GMOs. Freeze-dried for maximum nutrient retention. Beef Liver is ancestral nourishment the way nature intended.
Beef Liver is nature’s multivitamin — rich in preformed Vitamin A (retinol), B12, heme iron, copper, choline and folate. These nutrients support energy metabolism, skin and collagen integrity, immune function, thyroid health, and red‑blood‑cell formation.
Yes. Every batch is tested for heavy metals and microbial contaminants (bacteria, yeast, mold), among other quality checks. You can find the results in our help center.
The standard serving is five capsules per day. New to organ supplements? Start with 1-2 capsules and ramp up over several days. Take them all at once or split doses — both approaches work.
Any time. Many customers take it with their first meal. Consistency matters more than timing, and you can split the serving across the day.
Ye. Great pairings include Ironclad or Female Vitality (for extra iron support), Bone & Marrow, and Collagen & Colostrum. Avoid doubling up on liver‑heavy formulas (e.g., Beef Organs) unless you're aiming to increase your intake of specific micronutrients (e.g., Vitamin A).
Yes. You can open the capsules and sprinkle the contents on food or mix into a cool beverage. Expect a naturally rich, meaty aroma; avoid high heat to protect nutrients.
No. There have not been any reported cases of vitamin A toxicity from consuming the liver of ruminant animals (e.g., cows). All reported instances stemmed from consuming synthetic supplements or polar bear/seal liver (both of which have dramatically higher levels of Vitamin A than beef liver).
