Developed by neuroscientist Dr. Jack Jin and his team, the formula combines NMN, PRIOME® Mental Wellbeing Postbiotics and joint-support nutrients for aging dogs

WEST VANCOUVER, BC, CANADA, October 22, 2026 /EINPresswire.com/ — Dr. Jin Pet Essentials Inc. announces the launch of its Longevity Soft Chews for Dogs, a daily supplement formulated to support healthy aging, normal vitality and emotional balance in senior dogs.

Developed by neuroscientist Dr. Jack Jin, PhD, and the company’s product development team, the formula brings together nicotinamide mononucleotide (NMN), PRIOME® Mental Wellbeing Postbiotic Blend, a globally patented ingredient (protected under patent WO2021144333), glucosamine, chondroitin and antioxidant nutrients in an easy-to-give soft chew.

The product reflects Dr. Jin Pet Essentials’ focus on the everyday needs of small and senior pets. By combining several nutritional ingredients in one formula, the company aims to make daily supplementation easier for pet parents caring for aging dogs.

Key ingredients
• PRIOME® Mental Wellbeing Postbiotic Blend: A blend of heat-treated Bifidobacterium longum CECT 7347 and Lacticaseibacillus rhamnosus CECT 8361, clinically engineered to support gut-brain communication, cognitive health, and emotional stability in aging pets.
• NMN: A precursor to nicotinamide adenine dinucleotide (NAD+), a molecule involved in cellular energy metabolism.
• Glucosamine and chondroitin: Joint-support ingredients included to help maintain mobility in aging dogs.
• Antioxidant nutrients: Includes blueberry fruit extract and vitamin E to support the formula’s focus on healthy aging.

Research behind the postbiotic blend

A peer-reviewed study published in Cells in 2024 investigated a combination of the two heat-treated bacterial strains in C. elegans and zebrafish. Researchers reported changes in stress-related responses and anxiety-like behavioural measures, providing a basis for further investigation of the blend in animal wellbeing.

In an 8-week longitudinal UK cohort tracking approximately 120 completed canine participants administered 20 mg of PRIOME® Mental Wellbeing Postbiotic Blend daily, owner-reported metrics showed profound behavioral improvements. Specifically, the proportion of dogs exhibiting extreme excitability when visitors arrived dropped from 71.9% to 30.1%, severe noise sensitivity toward sudden or strange sounds decreased from 40.5% to 7.3%, and constant whining or barking when left alone fell from 34.7% to 7.3%, highlighting cumulative benefits over the 8-week duration.
