Antronex® is a Standard Process supplement built around the bovine liver (a source of the compound often called yakriton) with calcium. People reach for it as a daily support for the body's natural histamine response and healthy liver function.* Here's what it's used for, how much people take, and the cautions worth knowing.
Standard Process Antronex® is an extract derived from bovine liver fat that supports liver health and the body’s natural detoxification mechanisms. This extract, also known as yakriton, was originally discovered by Japanese researchers in the 1920’s.
Brand name Antronex®, produced by Standard Process, has been in use since 1953, when it was introduced as a liver health supplement. It is also rich in iron, folic acid, and Vitamin B12.
Standard Process Antronex® is commonly used to support liver health, respiratory immune response, and to control seasonal allergies and immune system function.
Our liver is responsible for over 500 vital functions, but some of its most important functions have to do with managing nutrient, chemical, and toxin levels in the blood.
After absorbing critical nutrients from digested food in the intestines, blood travels to the liver, where those nutrients are processed, converted, and sometimes stored for later use. When we ingest medications or toxic substances, these are also carried to the liver, where they are broken down for use in the body or removed as waste.
This detoxification process, also known as metabolic detoxification, occurs in three phases: activation, conjugation, and elimination. First, a collection of enzymes in the liver activate toxins, forming free radicals and reactive intermediaries. Then, a set of Phase II enzymes, including sulfotransferases and N-acetyltransferases, conjugate those intermediaries into water-soluble toxins that are then excreted from the body.
Antronex®, with its unique blend of antioxidants and compounds, supports the action of both Phase I and Phase II enzymes, leaving the body’s natural detoxification processes faster and more efficient.
Histamine is a signaling chemical produced by the immune system in response to allergens. Typically, we associate histamine with the itching, sneezing, and runny eyes that develop when we experience an allergic reaction. Histamine is broken down in the liver via methylation. Because Antronex® supports the liver’s detox mechanisms and helps the liver filter blood, it supports the breakdown of histamine and other inflammatory chemicals.

Antronex® assists the body’s natural antihistamine mechanisms by supporting the liver’s ability to filter blood. This can help speed up histamine breakdown.
Side effects of Antronex® include:
Standard Process Antronex® contains bovine liver extract, which is high in iron. Individuals with hemochromatosis and other iron metabolism disorders should avoid taking Antronex®. Individuals with known allergies to red meat should also avoid this product. Do not take Antronex® if you are pregnant or breastfeeding.
Standard Process offers a special formulation of Antronex® designed for pets called VF Antronex® for Pets. VF Antronex® for Pets offers appropriate dosing for both dogs and cats and can be used to support liver function, seasonal allergies, and immune response. Antronex® for Pets contains yakitron, a beef liver fat extract which has been studied in animals for over thirty years. In animals, yakitron assists with liver detox, accelerating the removal of histamine from the bloodstream, to ease itching, wheezing, and runny eyes caused by seasonal allergies. It can also help support general liver function.

Antronex® is a Standard Process whole food supplement that people use as daily support for the body's natural histamine response and for healthy liver function.
People often reach for Antronex® during seasonal changes when they want to support a normal histamine response, and practitioners also use it for everyday liver support. It's whole-food based and meant to be taken daily rather than as a quick fix.

Antronex is a whole-food supplement made by Standard Process, and it's made from defatted bovine liver (a source of liver factor, which Standard Process calls Yakriton), along with calcium.
Antronex isn't a drug or an isolated chemical. It's a food-based formula that gives your body nutrients that it recognizes. Standard Process sells it only through authorized health professionals.
No, Antronex is not a drug or a true antihistamine. It's a whole-food supplement that supports your body's own normal histamine response.
Over-the-counter antihistamines block histamine as a medication. Antronex works differently as nutritional support rather than a drug, so it doesn't act like or replace an antihistamine. If you take an antihistamine or any other medication, you should check with your practitioner or doctor before combining them.
Always follow the cautions on the label. If you are pregnant, nursing, or taking any medication (including over-the-counter), talk with your practitioner first, and keep the product out of reach of children.
Many people take it with meals. Your practitioner may adjust how much and how often you take it based on your situation, especially during seasonal changes.
Most people take Antronex without any issues, but as with any supplement, you should always follow the cautions on the label and any instructions given to you by your practitioner.
If you're pregnant, nursing, or taking any medication (including over-the-counter), talk with your practitioner first and keep it out of reach of children. Tell your provider what you're taking so they can check for interactions.
Antronex is a whole food supplement, not a drug. There's no set clearance time like there is for a medication.
It's meant to be taken consistently as a daily nutritional support, rather than a single dose that wears off. If you have a specific concern about timing it around other supplements or medications, talk about it with your practitioner.
They are the same Antronex formula, just in two different bottle sizes: 180 tablets and 330 tablets.
The larger 330-count bottle is the better value if you take it every day. Both are the same product, so pick the size that matches how often you use it.
Some practitioners do use Antronex with pets, but always check with your veterinarian before giving any supplement to a dog or cat.
Dosing for animals is different from people, so don't guess at it. Your vet can tell you whether it fits your pet and how much to give.
Antronex® is only sold through authorized Standard Process practitioners. You can order it directly from Snow Holistic Health.
Buying from an authorized seller means it's genuine, current, and stored right. Shipping is free on orders over $75.
