Antronex for Dogs by Standard Process: Allergy Causes, Care, Relief

As a holistic veterinarian, I spend a lot of time helping dog parents sort through allergy issues. Itching, licking, ear problems, digestive upset, and recurring inflammation are some of the most common concerns I see. In many of these dogs, the liver needs extra support.

One supplement I regularly reach for in these cases is Antronex® by Standard Process. It is simple, targeted, and has been used for decades to support the body’s normal detoxification processes.

Let me walk you through what Antronex is, how it works, and when it may be helpful for your dog.

What Is Antronex® by Standard Process?

Antronex® is a supplement made from bovine liver fat extract. This extract was studied by Japanese researchers for its role in supporting the body’s normal detoxification pathways.

In simple terms, it helps the liver do its job more efficiently.

The liver plays a huge role in how dogs handle allergens, toxins, medications, and metabolic waste. When the liver is overloaded, histamine and other inflammatory compounds can build up. That often shows up as itching, redness, ear infections, or digestive upset.

Antronex has a long history of use in both human and veterinary wellness programs. In dogs, it is most often used to support:

• Liver function

• Histamine balance

• Immune response

• Allergy-related symptoms

Antronex is gluten-free and does not contain artificial colors or flavors.

How Antronex® Supports Dogs With Allergies

When I see a dog with chronic allergies, I rarely focus only on the skin. I look upstream.

Here is how Antronex helps from the inside out.

Liver Support

The liver filters blood and helps clear histamine, which is a major driver of itching and inflammation. When liver function is supported, the body is better able to process and remove these compounds instead of reacting to them.

Histamine Balance

Histamine is part of a normal immune response, but too much of it leads to scratching, redness, and discomfort. Antronex supports the liver pathways that help clear excess histamine from the body.

Immune System Support

A well-functioning liver supports a balanced immune response. That means fewer overreactions to pollen, food proteins, or environmental triggers.

Digestive Support

Because the liver plays a role in digestion and nutrient processing, supporting it often improves stool quality, appetite, and overall gut comfort. This is especially helpful for dogs with food sensitivities.

Key Benefits of Antronex® for Dogs

Dog parents often notice gradual, steady improvements rather than dramatic overnight changes. That is exactly what I want to see.

Common benefits include:

• Reduced itching and licking

• Less redness and skin irritation

• Improved ear health

• Better digestion and stool quality

• Support for dogs with seasonal or environmental allergies

• Gentle support for senior dogs or dogs on multiple medications

Antronex is not a drug and it is not meant to suppress symptoms. It supports the body’s natural processes so your dog can respond more appropriately.

Ingredients in Antronex® by Standard Process

I always believe in transparency. Here is exactly what is in Antronex.

Nutrients Per Tablet

• Calcium: 30 mg

Proprietary Blend: 16 mg

• Bovine liver fat extract

• d-alpha tocopherol (vitamin E from sunflower)

Other Ingredients

• Calcium lactate

• Calcium stearate

• Acacia gum

Why These Ingredients Matter

Calcium supports normal cellular signaling and overall metabolic health.

Bovine liver fat extract is the core of this formula. It supports the liver’s normal detoxification pathways, which is key for dogs struggling with allergies or toxin overload.

Vitamin E is an antioxidant. It helps protect cells from oxidative stress and supports skin, immune, and overall tissue health.

The remaining ingredients help form the tablet and ensure consistent dosing.

Specific Health Issues Antronex® May Support

I most commonly use Antronex in dogs dealing with:

• Seasonal allergies

• Environmental allergies

• Food sensitivities

• Chronic itching or licking

• Recurrent ear inflammation

• Dogs with high toxic exposure or medication load

Because it works by supporting the liver, it often fits well into broader holistic protocols rather than being used alone.

Dosage and How to Give Antronex® to Dogs

General Dosing Guidelines

I often adjust dosing based on the individual dog, but these ranges are commonly used in practice:

• Small dogs (1 to 20 lbs): 1 tablet daily

• Medium dogs (21 to 50 lbs): 2 tablets daily

• Large dogs (51 lbs and up): 3 tablets daily

The manufacturer’s general guideline for humans is one tablet daily. Dogs with active allergy concerns often need higher dosing under veterinary guidance.

Always check with your veterinarian if your dog has complex medical conditions.

Administration Tips

• Tablets can be given whole or crushed into food

• Many dogs take it easily with meals

• Consistency matters, so try to give it at the same times each day

Antronex® is the same product as VF Antronex.

Safety, Side Effects, and Precautions

Antronex® is generally very well tolerated.

Possible side effects are uncommon but may include mild digestive upset such as loose stool if started too quickly or given in higher amounts.

To reduce the chance of side effects:

• Start with a lower dose for a few days

• Gradually increase to the full amount

• Always follow veterinary guidance

Stop use and contact your veterinarian if you notice vomiting, persistent diarrhea, hives, or breathing difficulty.

If your dog is undergoing chemotherapy or has advanced liver disease, consult your veterinarian or oncologist before starting any new supplement.

Store the product in a cool, dry place and keep it out of reach of pets and children.

How I Use Antronex® in Practice

I rarely use Antronex as a stand-alone solution. I see the best results when it is part of a comprehensive plan that may include diet changes, gut support, environmental management, and other targeted supplements.

When used correctly, it can make a noticeable difference in comfort and quality of life for dogs struggling with allergies.
