The formula, amount by amount.
Per level scoop, one scoop per 10 kg of dog, and per day for a 20 kg dog. The research belongs to each ingredient; it did not test BarkReserve itself.
| Active | Per scoop | 20 kg dog, per day | Layer |
|---|---|---|---|
Bioactive collagen peptides The body of the granule. Porcine type I peptides, the form used in the dog study. Randomised dog trial with force-plate gait measurement (2024). | 2,000 mg | 4,000 mg | Slow layer |
PEA (Levagen+®) Palmitoylethanolamide, a fatty-acid compound dogs make themselves. The fast layer. Randomised placebo-controlled trial in dogs with joint discomfort, 6 weeks. | 200 mg | 400 mg | Fast layer |
Eggshell membrane (NEM®) Naturally occurring collagen, elastin and glycosaminoglycans. Early onset in the research. Two dog studies, with change measured from week one. | 135 mg | 270 mg | Fast layer |
Green-lipped mussel Whole freeze-dried New Zealand mussel, lipid content stated on every batch certificate. Dog mobility trials at the maintenance level we use. | 190 mg | 380 mg | Medium layer |
UC-II® undenatured type II collagen The studied 40 mg a day. Works through the immune system, not through bulk. Several dog trials, including a force-plate comparison. | 20 mg | 40 mg | Slow layer |
Glucosamine HCl, plant-fermented The name owners look for, at a real amount, from a non-shellfish source. The most familiar joint ingredient, included at 25 mg per kg. | 250 mg | 500 mg | Recognition |
L-carnitine tartrate Supports normal muscle metabolism in older dogs. Senior-dog nutrition research. | 100 mg | 200 mg | Muscle |
Also contains beef liver digest and beef muscle powder (flavour coating), beef tallow and mixed tocopherols (natural vitamin E). Copper from the beef liver is kept under 0.1 mg per scoop.

Questions, answered.
How do I feed it?
One level scoop per 10 kg (22 lb) of body weight, once a day, to the nearest half scoop. The scoop has a half line inside. Mix it into wet food, or moisten kibble with a tablespoon or two of warm water so the granules cling.
What is actually in it?
Seven actives, every amount on the label: bioactive collagen peptides, PEA (Levagen+), eggshell membrane (NEM), green-lipped mussel, UC-II undenatured type II collagen, plant-fermented glucosamine and L-carnitine, in a beef-liver coated granule with natural vitamin E. No sugar, glycerin, dairy, soft-chew binders or synthetic preservatives.
How is this different from a chew?
Chews need binders, humectants and sugars to stay soft, and the actives have to fit around them. A granule is mostly active: the collagen peptides are the body of it. It also goes into food, so a dog that spits out chews does not get a vote.
When will I see a change?
Plan on weeks, not days. The fast layer (PEA, eggshell membrane) was studied for change inside the first weeks; the collagen layer keeps building past month three. That is why the guarantee runs 90 days.
What does the research say?
Each active has its own published research in dogs, and we list it on the formula page. Those studies tested the ingredients, not BarkReserve itself, and we say so. BarkReserve supports joint comfort and mobility; it does not treat or cure any condition.
Can my dog take it alongside medication?
The actives are food-derived and widely used, but if your dog is on medication, has a health condition or is pregnant, check with your vet first. Supplements support normal function; they are not a substitute for veterinary care.
When will my order arrive?
Orders ship and deliver within 3 business days, free, anywhere in the United States. Your plan then ships on its schedule, every 4 weeks to every 2 months depending on your dog’s size, and you are billed monthly.
How does the guarantee work?
Use it for up to 90 days. If you do not see a difference, or your dog refuses it, email us and we refund you. No return shipping, no forms.
Do you ship outside the United States?
Not yet. United States only for now.
