Works so well
My 12 year old Pit mix has a bilateral CCL tear and secondary arthritis. I’m happy to say that 1 TDC has really helped her mobility. I started noticing a difference about one week of taking the little capsules.

This has perked up my 18 year old cat. She was on it for about a week before she started hopping up in the bed again and being more active all around. She has joint, kidney and dental issues and this stuff have been a amazing supplement for her. I snip off the end of the pill and she licks it right off.

I started my dog on these after he was diagnosed with auto immune disease in his mouth. He would constantly get gum infections. My doggie dentist suggested that I use these in conjunction with brushing every day and using a couple of other things in his mouth (Maxi Guard Oral Gel and one other thing that I can't remember the name of).

Frequently Asked Questions
The following are the most frequently asked questions by other caring pet parents like you. If you don't see your question here, we're just a click or a phone call away.
How long until I see the benefits of TDC®?
Each pet is different, but it should be between 2-4 weeks. In some more sever cases, it could take up to 45 days to notice visible results.
Will 1-TDC® replace my dog's need for regular dental cleaning?
Teeth cleaning is important for removing tartar and plaque from your dog's teeth, an important part of oral health. 1-TDC® keeps the gums healthy, the major element of oral health. Ideally you want to do both. 1-TDC® complements teeth cleaning and other oral care procedures.
Can my dog with a beef allergy use 1-TDC®?
Yes. Allergies come from protein, and 1-TDC® is a fatty acid. So, any animals allergic to beef should be safe. Of course we recommend you consult with your veterinarian first who has a full medical history of your dog.
Are there any side effects of using 1-TDC® long term?
There are no known side-effects or contraindications with other medicines or products. 1-TDC® is intended for long-term use in dogs and cats throughout their life and they will not develop any resistance to the product.
Can I use 1-TDC® if my dog has health issues?
Like all other supplements, if you have a health issue going on with your pet, it is always recommended to discuss any treatments with your veterinarian. One case where you would not use 1-TDC® (and most other products) is if there is an active case of pancreatitis occurring.
Can I use 1-TDC® if my dog has health issues?
Omega 3 fish oils provide great general health benefits. However, when it comes to joint health, 1-TDC® provides superior results. Also, fish oils provide very limited periodontal benefit. Therefore, continue to use fish oils for general health and add 1-TDC® for superior gum and joint health results.
