Dog Dental Health Supplement: Science-Backed Support
Healthy teeth and gums are essential for dogs’ quality of life, and yet dental disease is among the most common health issues in dogs. Plaque builds fast, tartar follows, gums get sore, and breath… can get really bad, as many dog owners know! Many dogs face this cycle month after month. The problem tends to get worse with age - but the reality is that by age 3 the majority of dogs have some kind of gum or dental health issue.
The Marleybones Dental Health Supplement addresses this common situation with a blend of science-backed ingredients. The ingredients have been selected based on the results of peer-reviewed veterinary research to achieve one simple goal: support dental health, which in practice means cleaner teeth, fewer bleeding points, and fresher breath.

Active Ingredients, Mechanism of Action and Effect
1. Kelp - Anti-Tartar Support
- What it is: A seaweed rich in iodine, alginates, and polyphenols.
- How it helps: Daily kelp in dogs can aid lowering plaque and reducing tartar build-up. It can also help make tartar removal easier during cleaning. More specifically, kelp compounds can influence the mineral balance in the saliva, making it harder for plaque to harden into tartar!

2. Pomegranate Peel - Plaque Control Aid
- What it is: A polyphenol-rich product derived from pomegranate.
- How it helps: It disrupts the dental biofilm and makes it harder for plaque-forming bacteria to stick to teeth. As a result, it helps reduce plaque and tartar accumulation, as well as bleeding points. Additionally, it also has an antioxidant action that calms irritated gums, leading to improved gum health.

3. Green Tea Extract - Halitosis Management
- What it is: A decaffeinated source of catechins.
- How it helps: Catechins weaken plaque bacteria and slow biofilm growth. They also bind sulfur gases that cause bad breath. Pet studies show lower mouth odour after daily supplementation, with also substantial reduction in the growth of periodontal pathogens and gingivitis symptoms.
4. Fennel Seeds - Anti-bacterial
- What it is: A herb seed that contains natural oils like anethole and fenchone.
- How it helps: These oils can slow acid-making bacteria that contribute to dental plaque and harmful biofilm. They disrupt early biofilm so it matures slower, helping to maintain a cleaner oral environment for longer periods.
5. Parsley - Breath Freshener
- What it is: A herb rich in chlorophylls and polyphenols.
- How it helps: The bioactive compounds contained in parsley can help neutralise sulfur gases that cause bad breath and offer mild antibacterial action. That’s why it’s often included in toothpaste as well!

6. Spirulina - Periodontal Support
- What it is: A nutrient-dense microalgae rich in phycocyanin and other phycobiliproteins.
- How it helps: These compounds can calm gum inflammation and manifest an antioxidant action that lowers oxidative stress in oral tissues, supporting gum comfort and recovery.

Why The Formula Works Best In Combination
Each one of these six ingredients helps on its own, and their combined action gives broad support for oral health and fresher breath. And when provided in a daily chew, there is no need to hide pills or powders at mealtimes!
Key Benefits Include:
- Slowing new plaque and tartar with kelp-driven shifts in saliva minerals
- Targeting key plaque bacteria and odour gases with pomegranate and green tea
- Disrupting early biofilm with fennel
- Supporting gum comfort and recovery with spirulina
- Freshening breath with parsley
Owners tend to notice fresher breath before changes in plaque or tartar, since biofilm disruption affects odour faster. All the nutraceuticals here included work great alongside brushing and periodic professional cleanings for dental health maximisation!
