Many famous brands are behind Costco’s Kirkland line, delivering beloved food and beverage items hidden under a private label. Most often, the behind-the-scenes intrigue occurs in the liquor department, with consumers speculating about who makes Costco’s vodka or Kirkland Signature scotch. Yet even something as simple as a box of bagged Kirkland Signature Green Tea comes from an interesting origin.

As listed on the package, Costco sources this product from Japan, where it is made by the Ito En brand. The huge multinational beverage company is Japan’s biggest green tea seller, with a presence in over 45 countries. Its products span from the classic bagged green tea available at Costco to pre-bottled beverages, as well as a growing range of matcha items — a major source of revenue in recent years. The brand has even taken over the chain Tully’s Coffee, operating café outlets throughout Japan.

Such a giant tea venture is a perfect match for Costco’s mega-sized scale, with the collaboration spanning well over a decade. So the next time you’re grabbing tea bags at the warehouse retailer, know you’re buying from a reputable Japanese source.

Japanese Ito En makes the well-reviewed Kirkland Green Tea

Boasting a 4.7/5 rating with over 1,800 reviews as of December 2025, Costco’s green tea is a beloved retail item. Apart from concerns over the plastic-based bags, consumers rave about the brewed flavor, noting a balanced yet pleasant palate. The box — which retails at $13.99 for 100 tea bags — blends matcha and sencha, creating a beverage with a beautiful light green appearance.

The leaves are processed in a traditional Japanese manner. As opposed to the baking or pan-frying methods often employed for Chinese teas, Ito En steams its green tea, which establishes a light, vegetal palate. Once cooled, pressed, rolled, and dried, the product is well predisposed to retaining freshness, accounting for the slightly shorter shelf life of tea bags compared to loose-leaf teas.

The incorporated matcha also adds to the flavor, although it is simply blended into the bag — which means it doesn’t require a traditional metal or bamboo whisk. Instead, you’ll just need to steep Ito En’s Kirkland Signature tea for 30 to 45 seconds, and it’s ready to enjoy.

These are vitamins, minerals, amino acids, omega fatty acids, probiotics, and botanical extracts, which are aimed at promoting joint mobility, digestive, immune, skin and coat, and cognitive functions. The increase in pets and the tendency to ascribe human traits to them have made their owners act on long-term wellness in opposition to reactive treatment.

The market forces are the increasing knowledge on proactive pet care and the increasing cases of age- and lifestyle-related diseases that involve arthritis, obesity, allergies, and digestive disorders.

As the digital pet healthcare ecosystems increase, AI integration will probably be the subject of the development of precision nutrition and preventive care of companion animals.

Market Scope

Segment Insights

Pet Type Insights

Why Did Chewable and Soft Chews Contribute the Most Revenue in 2025?

Chewable and soft chews contributed the most revenue in 2025 and are expected to dominate throughout the projected period, as these chews are highly palatable and easy to administer. The soft chews are commonly viewed as either a treat or medicine, which keeps up with the current trend of humanizing pets and supplementing their wellness regularly. Their flexibility in formulation enables the manufacturers to incorporate several functional benefits, joint support, immunity, skin and coat, calming effects, etc., into one chew. In addition, the distribution of chewables through electronic commerce, pet specialty retail outlets, and veterinary hospitals is also high and contributes to the high volumes of sales. More innovation in both natural flavors and clean-label ingredients, together with breed- or life-stage-specific formulations, is also a factor in the long-term dominance of chewable and soft chew supplements.

The liquid and gel segment is expected to grow substantially in the pet dietary supplements market. The rising demand among elderly pets, small breeds, and those with dental problems or those that cannot swallow solid supplements is leading to growth. The liquid and gel formulations are easily administered and offer the right dosage, potentially allowing the pet owners and the veterinarians to modify the dosage based on the weight, age, and health condition. Emerging technologies for better flavor and natural preservatives have also served to improve palatability and shelf stability, which has overcome the challenge of adoption. Due to the current increase in awareness of geriatric pet care and proactive health, liquid and gel supplements will become more accepted both in the veterinary prescription market and in the direct-to-consumer market.

Supplement Type Insights

Why Did the Multivitamins Segment Lead the Pet Dietary Supplements Market in 2025?

The multivitamins segment led the pet dietary supplements market and accounted for the largest revenue share in 2025. Multivitamin supplements are a diverse source of the necessary nutrients, such as vitamins, minerals, and trace elements, and help to maintain health, immunity, metabolism, and vitality in all life stages. Their preventative placement is highly endorsed by the vet and readily accepted by those who are new to the use of supplements. Increased knowledge on balanced dieting and increased concerns about nutrient imbalances in commercialized pet food have further contributed to demand. The multivitamins also come in various forms, including chewable, powder, and liquid, and this increases access and convenience.

The CBD and hemp segment is expected to grow at a significant CAGR over the forecast period. These supplements are gaining popularity owing to the potential advantages they could have in the management of anxiety, reduction of pain, and improvement of mobility, specifically in older pets. Increase in regulatory clarity of the key markets, particularly North America, and in some sections of Europe, has facilitated product novelties and product commercialization. Owners of pets that are seeking another solution to pharmaceutical therapy are increasingly choosing to use CBD-based supplements to treat chronic diseases such as arthritis and behavioral disorders. This has been further improved by the formulation of standardized dosing, quality formulations, and third-party testing, which has boosted consumer confidence. Also, there is a slowing but growing interest of the veterinary community in cannabinoid-based therapies, which positively contributes to market growth.

Function Insights

Why Did Hip and Joint Health Supplements Contribute the Most Revenue in 2025?

The hip and joint health supplements contributed the most revenue in 2025 and are expected to dominate throughout the projected period. The increasing population of companion animals and the increasing rate of mobility-related illnesses such as arthritis, hip dysplasia, and joint stiffness are the primary sources of this leadership. Owners of pets are also spending more on preventive and long-term mobility products to enhance the quality of life and postpone surgical procedures. There is a rapid substitution of the traditional glucosamine only products with advanced formulations with UC-II collagen, green-lipped mussel, turmeric, and boswellia serrata. These are next-generation ingredients that have been supported by clinical research that has shown better pain reduction, inflammation, and cartilage protection. The demand is further enhanced by the availability in chewables, liquids, and powders, and hip and joint health supplements are the largest and oldest functional segments.

The calming and anxiety relief segment is expected to grow substantially in the pet dietary supplements market. Changes in lifestyle in the post-pandemic period, such as more owners being away and no longer having routines, have also added to stress, separation anxiety, and noise sensitivity in pets. The L-theanine, chamomile, valerian root, tryptophan, and CBD product line are becoming widely accepted to use every day with stress, with anxiety before traveling, and before any situation to calm down. These are supplements that are increasingly being included in evening routines, grooming routines, and travel preparations. A new market growth segment is likely to take shape as emotional wellness comes to be a central component of the holistic care of pets, and calming and anxiety relief supplements become a central part of pet care.

Pet Type Insights

Why Did the Dogs Segment Lead the Pet Dietary Supplements Market in 2025?

The preventive care practices in dogs are firmly established, and the owners of this species understand the payback on the investment in early supplementation more and more. The most important demand drivers in the canine segment are joint health and digestive support and dental care supplements, as mobility problems, gastrointestinal sensitivity, and oral health-related issues are prevalent. Also, the high prevalence rates of obesity in dogs have driven the demand for weight management and metabolic health supplements. Manufacturers are still increasing the number of breed-specific, size-specific, and life-stage-based formulations and making their products more relevant and purchaseable again.

The cat segment is expected to grow at a significant CAGR over the forecast period due to the growing awareness of feline-specific health needs and the growing contribution to research and development. Historically underpenetrated because of poor appreciation of the supplements, the segment is resounding because of the manufacturers focusing on the special dietary needs and the health conditions of cats, especially chronic kidney disease, health of the urinary tract, and digestive sensitivity. Increased palatability by use of sophisticated flavor systems and texture has highly contributed to compliance effects in cats. Liquid, gel, and powder preparations are gaining more popularity because they dissolve readily in wet food. There are increases in demand for preventive and condition-specific supplements as the population of indoor cats increases, and the lifespan of cats also increases.

Distribution Channel Insights

Why Did Specialty Stores Contribute the Most Revenue in 2025?

The specialty stores contributed the most revenue in 2025 and are expected to dominate throughout the projected period. These outlets have an exclusive stock of quality and condition-specific supplements so that pet owners can make informed purchases.

Specialty stores remain one of the main points of sale of dietary supplements, as consumers are more interested in pet wellness products of high quality and customization.

The online channel segment is expected to grow substantially in the pet dietary supplements market. The factors that promote growth include convenience, fair prices, and the rise in the number of people who buy the supplements on a subscription basis so that they can guarantee constant delivery. Mechanized delivery discounts and wellness packages make customers stay with them longer. Authenticated customer reviews and ratings are essential in the decision to purchase products, especially in the case of a first-time buyer. Online channels can also provide a wider variety of products, including niche and premium formulations that might not be found in physical stores. As the digital pet care ecosystems evolve and the consumers become more comfortable with the online healthcare purchase, the online channel will likely be a major growth driver in conjunction with the traditional specialty retail.
