Elevated liver enzymes, chronic medication use, or simply wanting to give your dog's liver a daily boost — these are situations where a targeted supplement can make a meaningful difference. The liver is responsible for filtering toxins, metabolizing medications, and producing bile for digestion. When it's under stress, the entire body feels the impact. Thera-Bites Liver Support from Aventix is designed to address exactly this need: a soft chew that delivers clinically studied liver-protective ingredients in a form dogs genuinely enjoy eating.
Aventix is a Burlington, Ontario-based animal health company that distributes veterinary-exclusive supplements across Canada. Thera-Bites Liver Support is part of their Thera-Bites line — soft chews formulated to combine palatability with therapeutic nutrition. This product is registered with Health Canada as a Veterinary Health Product.
Each chew delivers a combination of SAMe (S-adenosylmethionine) and silybin (from milk thistle extract), the two most researched ingredients in liver support for companion animals. SAMe acts as a methyl donor in hepatocyte repair processes and supports glutathione production — the liver's primary internal antioxidant. Silybin, the active flavonoid from milk thistle, has documented anti-inflammatory and antifibrotic properties in liver tissue. Together, they protect existing liver cells while supporting regeneration of healthy tissue. The formula also includes antioxidants to combat oxidative stress, which is a major driver of hepatocellular damage.
These chews are chicken-flavoured and soft, making them easy to administer as a daily treat. They're appropriate for adult dogs of all sizes, particularly those on long-term medications such as phenobarbital, NSAIDs, or steroids, or dogs with elevated ALT/AST enzyme readings on routine bloodwork.
Key Active Ingredients:
-
SAMe (S-Adenosylmethionine): Supports hepatocyte membrane integrity and glutathione synthesis
-
Silybin (Milk Thistle Extract): Anti-inflammatory, antifibrotic liver protection
-
Antioxidants (Vitamin E): Reduce oxidative stress in liver tissue
Directions for Use:
Give orally as a chew or mix into food. Dose by body weight as directed on packaging. Can be split into morning and evening doses. For long-term use in dogs on ongoing medications, daily administration is recommended. Consult your veterinarian for specific dosing if your dog has diagnosed liver disease.
Supplement Advisor's Note:
SAMe works best when given on an empty stomach for maximum absorption — this is true in both human and veterinary applications. If your dog takes this chew with meals, absorption is somewhat reduced but still therapeutic. For dogs on phenobarbital for epilepsy, regular liver support is genuinely worth discussing with your vet, as this medication is well documented to increase hepatic enzyme activity over time. Expect 4–6 weeks of consistent use before seeing improvements in bloodwork values.
Frequently Asked Questions
Q: How long until I see results in my dog's liver enzymes?
A: Most dogs show improvement in ALT and AST values after 4–8 weeks of daily supplementation. Your veterinarian will likely recheck bloodwork at that point.
Q: Can I give this alongside other liver supplements like Denamarin?
A: It's best to choose one primary liver supplement and stay consistent. Both contain SAMe and silybin, so doubling up is generally unnecessary. Consult your vet before combining products.
Q: Is this registered with Health Canada?
A: Yes. Thera-Bites Liver Support is registered with Health Canada as a Veterinary Health Product (VHP).
Q: Is this safe for senior dogs?
A: Yes, and senior dogs are actually among those who benefit most, as hepatic function often declines with age and many seniors are on multiple medications.
