    VF Antronex for Pets by Standard Process

    Antronex contains a highly specialized liver extract that acts like a natural antihistamine. Researchers in Japan have been studying and using these extracts since 1920.  The specific active ingredient is called “Yakriton”.

    The following information is a summary and review based on Dr. Candy’s professional experience and recommendations. Any summary or statement has not been provided nor influenced by the manufacturer.

    Dr. Candy And Other Holistic Veterinarians Use Canine Immune Support For: 

    • Food Allergies
    • Asthma
    • Hay Fever 
    • Detoxification
    • Insect Sting or bite
    • Exposure to Poison Ivy / Oak / Sumac

    Dr. Candy's Pro-Tip: Antronex works best in an acidic environment. If pH is too alkaline, there will be little to no anti-histamine reduction. Most people will need the systemic acidifier Cal-Amo. You can measure pH of saliva or urine using these easy strips

    More About  VF Thymex by Standard Process

    Detox of the liver is accomplished by the action of Yakitron that increases blood flow through the liver. Increasing blood flow decongests the liver and speeds up filtration. Secondarily, the liver is the organ responsible for removing histamines from the bloodstream. If the liver is clogged up histamine may accumulate in the blood. This can create an all over itchy reaction.  

    Side Note: The products of Antronex and VF Antronex are exactly the same. These are safe for dogs, cats and humans. Caution is recommended in people with high blood pressure, medicated or unmedicated. 

    Indications for Use: 

    • Neutralizing histamine
    • Detox the liver

    How to Administer

    Dose Schedule: Based on body weight, the canine patient should receive the VF formula tablet according to the following recommendations, or as otherwise directed.

    Special Information:

    Since these supplements are made from super foods, they are very "rich". This allows us to use small doses, but sometimes when adding a brand new savory food pets can experience a soft stool for 12-24 hours. This situation balances itself but I have found that using a gradual taper greatly reduces the chance of loose stool. 

    Caution: This product is processed in a facility that manufactures other products containing soy, milk, egg, wheat, peanut, tree nuts, fish, and shellfish.

    Please consult the actual product label for the most accurate product information.

    Ingredients: Each Serving Size (1 tablet) contains: Ingredients: Calcium lactate, bovine liver fat extract (yakriton), and d-alpha tocopherol (vitamin E sunflower). Other Ingredients: Calcium stearate and arabic gum.

    Guaranteed Analysis: Calcium (min) 30 mg/tablet

    Questions & Answers

    What are the side effects of VF Antronex?

    Since these nutritional supplements are made from food, there is little to no risk of side effects. The only side effect I’ve ever seen is diarrhea if the pet gets a gigantic dose. For example, if a pet eats a whole bottle. If I had a dollar for every time one of my pets ate a whole bottle, I’d have a pretty full piggy bank. Since pets love these products so much, we recommend keeping them in a cabinet or someplace that your pet cannot get to.

    How much VF Antronex should my pet take?

    • Dose Schedule
    • All cats, dogs < 20 lbs.: 1 tablet/day.
    • Dogs 20-50 lbs.: 1 tablet 2x/day.
    • Dogs > 51 lbs.: 1 tablet 3x/day.
    • OR as directed by your veterinarian.
