VF Thymex for Cats and Dogs by Standard Process- Uses, Benefits, Side Effects & Ingred.

By Dr. Candy Akers

I've been using VF Thymex for at least 7 years now. I have seen the cases where this supplement produced a significant effect on my patients. I've also seen a few where I did not see an obvious or significant result. This is my personal review, based on clinical evidence and nutritional science.

VF Thymex is a great supplement if you are looking for an immune system boost. VF Thymex targets the thymus gland. The thymus gland is the "master gland" of the immune system.

This Thymex supplement is not like most other Thymus supplements on the market. VF Thymex made by Standard Process is a super concentrated cytosol extract from the cells of the thymus gland.

The concentration of this product results in a large immediate boost to the immune system. 

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 VF Thymex Support For:

  • Feline Herpes Virus
  • Feline Calicivirus

Other VF Thymex Benefits:

  • Drain swollen lymph nodes
  • Quick boost to immune system
  • Powerful during the early days of infection, before antibodies develop
  • Delivers strength to the white blood cells
  • Helps clean up tissue damage

Dr. Candy's Pro-Tip: I have seen extremely fast recovery from infections in puppies when I use Standard Process Canine Immune Support. I believe it allows for lower doses of antibiotics and other medications. I use it in all of my rescue puppies and kittens.

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.

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

What our patients say:

My dog developed valley fever symptoms literally in 2 days as it attacked her spine. She couldn't walk. I thought I would have to put her down. Took her to the vet and theyPrescribed compound fluconozole. 2 weeks and no progress I thought this was the end. I was still carrying her everywhere. I got a referral to a different vet that specializes in valley fever and he prescribed HUMAN GRADE fluconozole (absorbs better and faster) standard process THYMEX and Canine immune support system. She was up and walking in 3 days! Standard process literally saved my dogs life. After Reading some of these reviews I am now going to order for myself as I have a thyroid issue that could use a little support.

My vet sold these to me (for a higher price than on Amazon) for my little boy Elliott. His fur was separating and lackluster. I gave him 2-3 daily and within 2-3 weeks, his fur looked gorgeous again. The fur separating was a sign that what was going on inside wasn't great either. I'm purchasing more, I hope he'll devour again like he did the 1st bottle. Maybe I'll try some myself & see what they do for me.

Questions & Answers

What are the side effects of VF Thymex?

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.
