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.

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.
