Whole Herbs, Real Benefits
Dehydrated Calcified Seaweed
Calcified seaweed forms a mineral-rich structure as calcium carbonate is deposited in its tissues. Animal Essentials selects this marine ingredient for its mineral contribution to bone and structural health.
Dehydrated Calcified Seaweed
Green-Lipped Mussel
Green-lipped mussel naturally contains marine lipids and glycosaminoglycans, long chains of sugar units also found in connective tissues such as cartilage. Animal Essentials includes green-lipped mussel for joint structure, mobility and physical comfort. Green-lipped mussel is a shellfish.
Green-Lipped Mussel
Yucca Root
Yucca root traditionally supports comfort. Its role in Sea-Flex fits the formula’s support for occasional stiffness associated with everyday activity and joint mobility.
Yucca Root
Horsetail Herb
Horsetail herb is the above-ground portion of the plant and naturally contains silica within its tissues. Animal Essentials selects horsetail for connective-tissue and structural support.

Licorice Root

Astaxanthin
Astaxanthin is a carotenoid, a member of a family of naturally occurring pigments. It is selected here for antioxidant support, helping protect cells from oxidative stress caused by reactive molecules called free radicals.

Frequently Asked Questions

Yes. Dogs receive a weight-based serving; cats receive ¼ scoop (¼ tsp) once daily.

Marine ingredients support the formula’s joint and mineral foundation, while yucca, horsetail and licorice contribute herbal support for comfort and connective tissues. Astaxanthin adds antioxidant support.

Best if administered directly into mouth or combine with your pet’s regular routine, once daily.

One scoop equals 1 tsp.

Use consistently as part of an ongoing mobility plan. Track comfort and movement over time; individual responses vary. Persistent stiffness, pain or reduced activity warrants veterinary assessment.

Ask a veterinarian to review the combination before use. Other joint formulas may duplicate shellfish, minerals, licorice or other ingredients, and suitability depends on the pet’s medical conditions and medication.

No. The product is not artificially flavored. Its natural taste and aroma come from the formula itself.

The extra space in the jar leaves room for the scoop and makes it easier to measure the powder, helping reduce spillage.

Best Joint Supplement for Dogs

Ive given this supplement to my dogs for 10 years. Noticed a big difference in their digestion when I stopped for a few months. But I've started adding it to their food again. I won't stop again!

Good product

I started buying this brand from the pet food store near my house. I know the owner won't sell anything that she would not use for her own dogs. So I knew it was a good brand. I have a 10 year old Weimaraner and have been using this for a while now. And he is doing well on it. I did find it a little cheaper on Amazon than at the pet store. I put it in his morning food along with the Omega 3 I give him each day.

This has been a really good joint support powder for my pets. My only issue was the Prime delivery delay, so give yourself extra time in case shipping slips.

Helped my young dog look and feel better

I inherited a 1 year old dog who was already on this and there was still a little left in the bottle. Her overall condition was amazing, and she moved so comfortably that my dogs paled in comparison. I bought the larger bottles so I could get everyone on it.

Works well

Works really well to help my aging dog with joint stiffness and mobility. Nice that you give it once a day versus with every meal. Easy to mix in with her food and she does not notice it.
