All my dogs get 1-TDC®

I’m happy to stand up and wave the flag for 1-TDC®. My dog Encore is absolute living proof of what a difference it made to her leg. For 2 years we had to lift her to get into the motorhome. She now flies up and down the motorhome steps all on her own. All of my dogs get 1-TDC®

~ Susan Garrett, Multi-Time National & World Champion of Agility

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

Our veterinarian is very impressed with how great my dog’s gums & teeth are!

Love the bargain & the product! Have been using 1-TDC® for years! Our veterinarian is very impressed with how great my dog’s gums & teeth are!

~ 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.

~ Anji from Alberta, CA

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.

~ Judi Schachte

Here are answers to some FAQ’s

Can my cat also take this supplement?

Yes, it is the exact same product for both dogs and cats.

How long until I see the benefits of TDC®?

Each pet is different, but it should be between 2-4 weeks.

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. 

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.

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.

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.

Can I use 1-TDC® in combination with other supplements like fish oil?

1-TDC is totally compatible with other supplements you may be using. Our CMO suggests cutting the dosage of fish oil by 50% if you are giving your pet a fish oil supplement.

How palatable is 1-TDC®?

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

When should I start my dog on 1-TDC®?

Our Chief Medical Officer, a boarded veterinary dentist with over 40 years of clinical experience, recommends you start once your dog's adult teeth are in (around 6 months of age). 

What time of day am I supposed to give 1-TDC® to my dog?

You can give your dog 1-TDC® whenever it is convenient for you. Before meal, after meal, with meal, morning, evening ... it doesn't matter.

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.

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 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.

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

No. Soft gels get soft in warmer, humid weather and hard in cooler, dry weather. If yours are hard, a trick to keeping them softer (easier to use) is to put a little piece of bread in the bottle much like you do with cookies to keep them from getting stale/hard. The moisture in the bread will soften the soft gels.

My capsules are stuck together. What do I do?

If the capsules are stuck together, you can put the bottle in the refrigerator for an hour and then just shake the bottle to unstick the capsules. If that doesn’t work, give us a call and we will send you a replacement bottle. We want you to be happy and we do not want your money if you are not.

Why is the gel color and texture different from my last bottle?

Color changes from batch to batch are normal. When you squeeze out the contents of the capsule it should be an oily paste. If the product has separated into an oil and a grainy substance, then the capsules were exposed to high temperatures in transit for too long.

Worry not, however, because its efficacy or safety doesn't get affected by high heat. That being said, if that’s the case and you’re still skeptical, or its just difficult to administer it in a liquid form … give us a call or email us and we will send you a replacement bottle for free.

My dog doesn't like the supplement. What do I do?

It may take a while for some pets to get accustomed to the product. Squeezing the capsule contents into an empty dish and then putting a little treat in the 1-TDC® paste helps.

Eventually, when you shake the bottle, your dog will come running. As a last resort, you can put 1-TDC® paste on the pina of the ear, and remove it after 10 minutes. That way it will absorb into the dog’s system.

What does 1-TDC® stand for?

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

What is 1-TDC® made of?

1-TDC® is a proprietary blend of fatty acid oils from USA beef tallow.  The two key ingredients are 1-TetraDecanol Complex (1-TDC®) from beef tallow and Wild Alaskan Salmon Oil. Every batch will have the same efficacy your dog's health can rely upon. 

The ingredients we use and the manufacturers and packagers we use are all cGMP certified and all the product ingredients are human grade. 1-TDC® is as high-quality of a supplement as you will find and is backed by a 100% satisfaction guarantee. It is entirely made in the USA.

When can I find 1-TDC® research information?

Published research can be found here: 

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.

Great product! We love it!

We have been using 1-TDC since Luna was a puppy. She is now 4 years old. She loves her little heart shaped
1-TDC treats. This is part of our dinner routine. She is a strong muscular lab and I truly feel that 1-TDC is keeping her joints healthy. At her last check up our vet commented on how beautiful her teeth are and said “ I wish my dogs teeth looked that good!” Thank you!

Robin Taylor
Love it!

Johnny is a 12 year old Rat terrier who has been on 1TDC for 8 years. He has only had 1 dental and only because they thought he had a cracked tooth. The Vet cannot believe how great his teeth look for his age. He was the #3 Rat terrier AKC agility standing for last year. He is still competing at a hight level just earring his Agility Grand Championship last month. He is running beautifully, happy and healthy thanks to 1TDC.

30 day use so far

Rosie’s (11 year old senior) teeth and gums have definitely improved already, and I’ll be curious what the vet says at next well check. Breath has also. As for mobility, difficult to tell at this point since the weather has been so hot and haven’t had a chance to see a difference in her arthritis. But she certainly is getting up and down stairs without a problem.

Pauline Bryant
Great for teeth

We are still fairly new at this but so far we’ve noticed a great improvement on our dog’s teeth. Can’t wait to see what continued use does for joint paint!

Heather Gregorio
“Vitamin Time”

I looked into the benefits of 1-TDC as i have an 8 yr old pup who I wanted to make sure was comfortable as she moved into her senior years. As well I have a 2 yr pup that has flaky skin. It’s my hope that by starting these two on this supplement that I can prevent or at least delay future concerns. In the month of using 1-TDC the 2 yr old no longer has flaky skin, and the 8 yr old seems to be moving a little easier. And I know both dogs love it as they come running when I say it’s “vitamin time”.
