The 4-in-1 Advanced Approach to Joint Health

Our veterinary team developed MULTIFLEX™ around six key ingredients that support healthy joints and mobility.

Cartilage Cushion Support

Delivers key building blocks that help maintain cartilage proteoglycans and collagen structure – supporting cushioning and joint lubrication.

Inflammatory Response Support

Helps support oral tolerance through the gut-associated immune system, helping the body maintain normal joint cartilage and healthy movement.

Supports Balanced Immune Health

UC-II works through the immune system to help the body maintain healthy joint cartilage and mobility.

Supports Connective Tissue

Supplies collagen, amino acids, and sulfur compounds that help maintain healthy cartilage, tendons, and ligaments – supporting stable and resilient joints with every step.

Joint Health Simplified. One Daily Pack.

UC-II® works at a low dose—making one daily stick pack a full-strength serving.

Add this supplement to your dog’s daily meal if he is struggling with mobility as he gets older.

I am giving this to my senior dog for a few months now, and I have seen some improvement in his mobility. So glad we found a supplement that is helping him as he enters this part of his life.

Worth it!

My 10 year old border collie mix noted relief after 1 month of being on this supplement. She has been on a biological treatment that had started to not work very well so we added this. She went from barely getting around most days to being able to navigate better. I feel like it has improved her quality of life. Worth it!

We Want You To Question

Can I give my dog MULTIFLEX™ along with the Daily Multivitamin (DM-01™)?

Yes! MULTIFLEX™ was formulated to be safely taken alongside our DM-01™ Daily Multivitamin. In fact, they complement each other—DM-01™ covers your dog’s daily nutritional needs, while MULTIFLEX™ provides advanced hip & joint support.

At what age can my pup start using this?

MULTIFLEX™ is suitable for dogs of all ages and breeds. However, we do recommend dogs begin to incorporate the powder into their daily routine starting at an age of 6 months or older.

What does 100% Human-Grade ingredients mean?

Most pet supplements from other brands contain palm oil, fillers, artificial flavoring, preservatives, etc. At Dog is Human, we’re raising the standards of pet health by only using the highest quality human-grade ingredients, which is what our best friends deserve.

How long until I start seeing the benefits?

Like any wellness routine, consistency matters. If taken consistently on a daily basis, most dogs will start to see positive changes in about 6-8 weeks.

How many packets come in a box?

There are 30 packets in each box, which is a 2 month supply for Small Dogs (0-25 lbs) or 1 month supply for Medium and Large Dogs (25+ lbs).

How do I give the powder to my dog?

Tear open the stick pack and serve at mealtime. Most dogs enjoy the flavor and won’t even notice it’s there.

What happens if I accidentally give my dog too much powder?

In the event that your dog accidentally consumes significantly more than the daily recommended dose, consult your vet for advice.
