Starting in late 2024, we’ve been updating our VetriScience® packaging with easy-to-understand product names, ingredient information, product benefits, and feeding directions. While our look has changed, the products are the same great science-backed formulas you know and trust.

VetriScience® started rolling out a new look in late 2024. To minimize waste, we’re running through existing packaging on-hand before transitioning to the new design. This will ensure a smooth transition from previous packaging to new packaging and maintain the quality of our processes and products. During these phases, you may receive both previous and new packaging in the same order, depending on what products you ordered. Regardless of packaging, know that you'll be receiving the same high-quality pet supplement products that you've come to expect from VetriScience®.

One of the primary functions of one-way valves is to preserve the freshness of our products. Like many packages goods, such as coffee, naturally release gases after packaging. If these gases are trapped inside the bag, they can negatively impact the product's taste and quality. The valves ensure that these gases can escape, keeping the contents fresh and full of flavor. By preventing air from entering the bag, one-way valves help maintain the quality of the product by reducing the risk of oxidation. The ability to release gases without letting air in also contributes to a longer shelf life for our products. This means your pets can enjoy our products at their peak freshness for a longer period. If you have any further questions or concerns, feel free to reach out to our customer service team. We're always here to help!

As part of our new look, we updated our product names to better reflect the benefit and purpose of each supplement. You can still find all the products you're looking for within their category pages or by searching the product number. See our blog for a full list of new product names.

We listened to our customers—with such a large selection of premium pet supplements, pet parents needed an easier, cleaner way to shop for products. For example, Acetylator™️ is now Healthy Gut & Digestion, and Perio Support is now Healthy Mouth. You can still find all the products you're looking for within their category pages, or by searching the product number. See our blog for a full list of new product names!

No! While our product names and packaging designs are all new, our science-backed and vet-developed formulas have not changed at all. We're still making the same great products, manufactured in the U.S. in FDA-registered facilities to the same high standards set by the NASC (National Animal Supplement Council).

See Shipping & Returns Policy details here.

Our products have been manufactured in U.S. facilities for over 40 years. Our manufacturing facilities are SQF-certified and strictly adhere to NASC guidelines and Current Good Manufacturing Practices (cGMP) as defined by the Food and Drug Administration.

The ingredients used in VetriScience® supplements are sourced globally, with many coming from the U.S. Our ingredient suppliers must undergo a rigorous application process to ensure their raw materials meet our strict quality standards. All of our ingredients are third-party tested to guarantee quality and purity. VetriScience® products are formulated to comply with regulations set forth by The Association of American Feed Control Officials (AAFCO) and the National Animal Supplement Council (NASC).

We do not recommend off-label usage of any of our products. We take great care to formulate each product to be specific to the needs of cats or dogs, from nutrients to flavor and palatability.

Dosing instructions are located on the back of each product's package or bottle and on each of our product pages.

Increasing your pet’s dose is not recommended unless specifically noted on the packaging. For example, it is suitable to double or triple the dosage of Composure™ during times of heightened stress.

Every product undergoes strict palatability testing before we put it on the market, but picky pets may still need some encouragement. Check out our blog for tips! For dogs, you can use pill-hider chews for capsules or tablets. If your pet still won't eat the supplement, you can return the product for a full refund. See Shipping & Returns Policy details here.

We take poor reactions to our products very seriously. Since our products are intended for supplemental feeding, they’re typically well-tolerated by cats and dogs. However, if your pet had too many, they may experience digestive upset since the high nutrient levels in products can be too rich for their stomach. If you believe our products made your pet sick and you have immediate concerns, please contact your veterinarian as soon as possible. Otherwise, please contact our customer care team at 1-800-882-9993 to report this issue so we can further assist you with this matter.

In many cases, VetriScience® products can be administered together without issue. However, we always recommend consulting with your veterinarian to determine if the combination is suitable for your cat or dog and their unique health needs.

While we take great pride in the palatability of our soft chews and chewable tablets and your pet may think of them like a treat, VetriScience® products are supplements made with beneficial levels of vitamins, minerals, and other dietary compounds. Supplements are not formulated to be used as a treat or training aid. Giving more than the recommended number of chews or tablets per day is not recommended.

Short-term exposure to extreme elements should not affect the product. Stability studies show that any changes to products during shipping are minimal. However, if your product smells rancid or appears discolored, please contact us at 1-800-882-9993 to report this issue. If you believe our products made your pet sick, please contact us at the same number to report this issue so we can further assist you with this matter. If you have more immediate concerns, please contact your veterinarian as soon as possible.

Although this is a very rare occurrence, please return the product to the original retailer if it’s improperly sealed. They will provide you with a replacement product at no cost to you. Please contact us at 1-800-882-9993 should you have any difficulty with this process.

Maturing pets experience considerable wear and tear on their joints. A decrease in the production of joint fluid can contribute to joint discomfort, which is common in both dogs and cats. A strong inflammatory response isn’t always apparent, as pets are often seen as “slowing down due to age” rather than slowing down due to discomfort. In many cases, the utilization of joint supplements can help improve the inflammatory response and improve quality of life at any age.

When should I start giving my pet joint supplements?

Symptoms of joint discomfort may include limping and vocalizing but are often more subtle. Your pet may sleep more or start to struggle with everyday activities like walking and jumping. They may have a harder time standing up. Keep an eye out for signs of discomfort like trembling, irritability, loss of appetite, hiding, or licking of the affected joint.

Glucosamine is one common component found in many over-the-counter (OTC) joint supplements. However, Healthy Hip & Joint (previously GlycoFlex®) is formulated specifically for pets and contains additional active ingredients that work together with glucosamine to provide better support.

Be aware that many OTC glucosamine supplements fail to prioritize quality and safety in their products. VetriScience® has received certification from the NASC (National Animal Supplement Council) that reflects our commitment to quality, efficacy, and purity. Healthy Hip & Joint is made in an SQF-certified facility and manufactured in the U.S. with the highest quality ingredients sourced from around the world.

Healthy Hip & Joint (previously GlycoFlex®) works with your pet's body to promote healthier cartilage and joints, support a healthy inflammatory response, and support limb strength and mobility. For pets who are already showing signs of joint discomfort, Healthy Hip & Joint joint supplements can help restore their comfort and vitality. For pets not showing signs of discomfort, Healthy Hip & Joint can keep joints healthier, longer.

Healthy Hip & Joint (previously GlycoFlex®) doesn’t require a prescription, can be purchased at many pet stores or online, and is safe to give to most pets under the direction of their veterinarian. While we always encourage you to consult your vet whenever you consider a new supplement, you can feel comfortable starting your cat or dog on a Healthy Hip & Joint joint support product today!

Ultimate Strength Healthy Hip & Joint (previously GlycoFlex® Plus), our most powerful formula, contains a unique combination of 11 active ingredients, including GlycOmega® brand Perna canaliculus (green-lipped mussel), DMG, glucosamine, chondroitin, and MSM. All ingredients in our Healthy Hip & Joint line of joint support products have been extensively studied. This unique combination of ingredients helps to soothe discomfort while providing the building blocks to support healthy recovery and healing.

Green-lipped mussel, also known as Perna canaliculus, is packed with healthy nutrients like omega-3 fatty acids and natural compounds including glucosamine and chondroitin that can improve joint health and support a healthy inflammatory response. Several studies have been performed to test the efficacy of supplementing with green-lipped mussel and found that this super shellfish can have a significant impact on comfort and mobility.

Typically, it takes 4 - 6 weeks to see the full effect of Healthy Hip & Joint (previously GlycoFlex®) on your pet. However, when used as recommended, you may start to see gradual improvements in comfort, mobility, energy, and attitude within the first few days!

On all VetriScience® products, the expiration date is located next to the lot number on the back of the package or bottle. The lot number is 8-9 digits long, then a space, then 4 more digits indicating month and year. For example: a product with numbers “999999999 0125” would expire in January 2025. We do not recommend usage of Healthy Hip & Joint (previously GlycoFlex®) after the expiration date.
