Beef Liver

Read reviews

Across cultures throughout history, liver has been recognized as one of the most nutrient-dense foods available, used intentionally to restore energy, support blood health, and promote fertility. Beef Liver is rich in retinol (vitamin A), B vitamins (including folate), copper, zinc, selenium, choline, CoQ10, vitamin K2, and more. These nutrients are naturally bound in peptides and amino acids, accompanied by cofactors, enabling effortless absorption and rendering them far superior to their synthetic counterparts. Frtil Beef Liver is sourced from grass-fed and grass-finished New Zealand bovine and freeze-dried to preserve and optimize overall effectiveness.*

Freeze-Dried Beef Liver
Why It Made the Formula

Beef liver is one of nature’s most nutrient dense foods, providing naturally occurring retinol, B vitamins, copper, iron, choline, and more. Its broad nutrient profile makes it an ideal foundation for daily nourishment.

Behind Every Bottle

No fillers or flow agents. Third party tested. Food as our starting point.

Premium raw material

Our beef liver comes from 100% grass-fed and finished cattle raised entirely on pasture by small family farms in New Zealand. It is flash frozen shortly after harvest, then freeze-dried raw (without heat) to help preserve its delicate nutrient profile.

Made to stand apart

We did not assume our liver was the best. We tested it. Not only for purity, but for its complete nutrient profile. Every batch of raw material is tested, so you know exactly which micronutrients you are receiving and in what amounts.

Beef Liver FAQ's

What are your capsules made from?

Our capsules are made from 100% non-GMO bovine gelatin and contain no pork.

Is this product histamine-friendly?

Yes. Our beef liver is flash-frozen immediately at harvest, with no aging of the raw material. This process is often better tolerated by those sensitive to histamine.

Is the beef liver raw?

Yes. Our beef liver is never heated and is freeze-dried in its raw state to preserve its nutrient integrity. Freeze-drying is the gold standard for preserving food because it gently removes water without heat or oxidative damage, locking in vitamins, minerals, and enzymes almost exactly as nature made them.

Is Beef Liver safe to take during pregnancy?

Ancient civilizations recognized the nutritional density of beef liver, often valuing it as a sacred food for fertility and pregnancy. Gram for gram, it remains one of the most nutrient-dense foods available. That said, pregnancy is deeply personal. We always encourage you to speak with your practitioner to determine what is best for your individual needs. To support that process, we test every batch for full nutrient content, so you know exactly which nutrients you are receiving and in what amounts, in each serving.

What’s the difference between Beef Liver and Beef Liver (B9)?

Beef Liver is our classic formula: 100% grass-fed and finished, freeze-dried beef liver sourced from New Zealand. Beef Liver (B9) builds on this base by adding organic lemon peel for natural folate and a bit of zinc glycinate to support an optimal 8:1 zinc-to-copper ratio. Each batch of beef liver is tested for naturally occurring copper and balanced accordingly with zinc glycinate. This formula is well-suited for both men and women trying to conceive, as well as women who may benefit from additional zinc to antagonize the naturally occurring copper found in liver.

When should I take Beef Liver capsules?

Many find that liver supports energy levels due to its high nutrient density, so we recommend taking it earlier in the day to avoid interfering with sleep.

What nutrients are in beef liver capsules?

FRTIL Beef Liver is the only beef liver on the market that tests every batch for nutrient content. We know, not just claim, that our freeze-dried liver is naturally rich in vitamin A, B vitamins, copper, and iron. These nutrients remain bound within their whole food matrix alongside essential cofactors, peptides, and amino acids for meaningful bioavailability and effortless absorption.
