My dog , Lily, (13) was beginning to slow down. She walked so slowly. Now because of 1-TDC® she runs and walks like a younger pup.

“Based on a study I performed at The University of Saskatchewan, I was amazed at the positive results from the use of 1-TDC® technology (unique fatty acid oils). All periodontal measurements in the test animals improved significantly. The more I use the 1-TDC® technology, the more impressed I am.”

Westminster Agility Grand Champion uses 1-TDC®!



Within days I could notice a difference...

I first started using 1-TDC® in the fall of 2014 on my Sheltie who was showing a bit of stiffness. Within days I could notice a difference in his mobility so I began using the product with all my dogs. I cannot believe the difference it has made for my dogs dental health and that remains my favorite feature. I started telling my friends about this product and now they come to me raving about the difference it has made for their dog too.”

What Some Of Our Customers Are Saying


She's now back to her happy, bouncy self.

I read about 1-TDC® and after three months of her being a recurrently sore and mopey pup, I decided to give 1-TDC® a try. I rub one capsule on her gums every morning and she happily eats the rest of the capsule. It has made a huge difference. She's now back to her happy, bouncy self. Her extra clean teeth and breath are a great bonus.

~ Fran from California

~ Deborah from Granada Hills, CA

I’ve noticed a difference in their skin, coat and teeth!

My dogs really love this product! From my 6 month old puppy to my 13 year old senior. I’ve noticed a difference in their skin, coat and teeth! Highly recommend.

~ Fran from California

Not only does his teeth look great but he has become puppy like.

I started my now 11yr old Australian Shepherd Summit on 1-TDC® over a year ago hoping to see some dental benefits. Not only does his teeth look great but he has become puppy like. His play time has increase and he continues to shine in agility.

Here are answers to some FAQ’s

My pet ate the capsule, do I need to take it to the vet? 

No, the capsule is made to be ingested.

My pet ate more than the suggested dosage, do I need to go to the vet?

No, usually they will be just fine. Worst case, maybe some diarrhea.

I’m supposed to give 2 capsules, does it have to be in the morning or evening?

You can give your pet 1-TDC® whenever it is convenient for you.

Do I have to put 1-TDC® on the gums?

It is recommended, but not necessary. Feeding them the capsule or contents works just as well.

How long until I see the benefits of 1-TDC®?

Each pet is different, but it should be between 4-6 weeks.

Is the loading dose necessary?

If you have a young, healthy pet and you are being proactive, the loading dose is not necessary. If your pet is older or has oral health or mobility issues, then I would suggest the loading dose to get the 1-TDC® into the system faster.

What kind of fish oil is in the 1-TDC®?

Wild Alaskan Salmon oil.

If my pet does better on the loading dose, is it ok to keep them on that?

Yes, every pet is different, keeping them on the loading dose is ok.

My capsules are harder than the last bottle, are they bad?

No, air in the bottle will make them hard, add a small piece of bread to the bottle and the capsules will soften (just like adding a piece of bread to a container of cookies.

Where is our product made?

In the US.

What does 1-TDC® mean?

1-TetraDecanol Complex, which is the molecular name. 1-TDC® is a patented blend of fatty acid oils.

What is 1-TDC® made from?

1-TDC® is a proprietary blend of fatty acid oils from beef tallow derived from grass-fed animals.

If my pet is allergic to beef can I use 1-TDC®?

Yes, allergies come from protein and 1-TDC® is a fatty acid. So, your pet should be safe.

What are the major differences between 1-TDC® and fish oil?

1-TDC® has an affinity for white blood cells, which makes it a more targeted and effective solution. Additionally, 1-TDC® is transdermal, which gives it the ability to effectively be absorbed and work locally.

Does 1-TDC® replace the need for fish oil?

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.

How does 1-TDC® as a joint health solution compare to glucosamine, HA & fish oil?

1-TDC® provides superior results due to its unique properties. Put it to the test. We provide a 100% satisfaction guarantee.

Is 1-TDC® economical?

YES, it is significantly less expensive than other joint health products and provides twice the benefits, supporting both gum and joint health.

How long before I see results?

Joint health improvements are typically noticeable in one week for small dogs and cats; two weeks for medium size dogs; and three weeks for large dogs. Periodontal improvements can be seen as early as one week and steady improvement will continue over the next two months. Again, steady improvement can be expected over the following two months.

How palatable is 1-TDC®?

Extremely palatable, since it is derived from beef tallow. Pets see it as a treat...even cats.

Does 1-TDC® replace the need for a dental cleaning?

NO. Teeth cleaning is critical to remove plaque and tartar, a key element to oral health. 1-TDC® addresses the other part of oral health. It targets the health of the gums directly. 1-TDC® should be used with every dental cleaning and procedure because it complements and enhances those procedures. Additionally, 1-TDC® is an excellent choice in situations when teeth cleaning cannot be performed for some reason.

Bad breath

I have a 15 year old Border Collie whose teeth and gums were looking pretty bad. She loves taking her 1-TDC 'treat' before bed every evening and we love how her 'old lady' breath has gone away! Also, teeth and gums look better. She has arthritic hips but we haven't really seen improvement in that area other than she's still able to do 1-2 mile walks with us, even running a bit occasionally. Happy about that!

Nancy Kaplan
Love this product !

I have been giving my 6 year old dog 1-TDC since she was a puppy. Our vet always comments on how wonderful her gums and teeth are. As she gets older I feel great about how good it is for her hips and joints.

Bad breath

I bought this for my Border collie that has periodontal issues, her breath doesn't smell like road kill a month after her teeth cleaning.
