Xylitol has decades of clinical data: better salivary pH recovery in a controlled trial of 90 children, and lower mutans streptococci counts in 12 of 14 comparisons in a 2025 systematic review. Contact time is the mechanism. This is 900 mg of birch xylitol, portioned to swish. Keep it away from your dog - xylitol is genuinely dangerous to them.
For adults who want something to swish after brushing or before a meal. 204 capsules.
- Lab Tested
- 100% Birch Xylitol
- Single Ingredient
- Pork-Free Capsule
Why people use it
- Supports salivary flow and a normal oral pH. In a controlled trial in 90 children, salivary pH differed significantly after 15 minutes of xylitol gum versus a plain pellet, and the authors put it down to stimulated salivary flow.
- Supports a balanced oral environment. A 2025 systematic review found xylitol gum lowered mutans streptococci counts in 12 of 14 comparisons against sorbitol gum, and plaque in 6 of 10.
- Contact time is the whole mechanism. A 2024 review found xylitol gum worked and xylitol candies generally did not. Everything measured in the literature came from something held and worked in the mouth. That is why the instruction is swish for 30 to 60 seconds, not swallow and go.
- One ingredient, and the number is on the label. 900 mg of 100% xylitol from birch trees per capsule, in lab-tested pork-free bovine capsules.
- Open, swish, spit or swallow. Oral Hydrate is designed to be used as part of a routine that supports oral moisture, comfort, and pH balance. Xylitol is often chosen for its refreshing qualities and its role in supporting a clean, balanced oral environment.
What you're getting (approximate)
Per 1 capsule (900 mg xylitol). Label figures come from our label; estimates come from published food-composition data applied to this serving size.
| Nutrient | Per serving | Basis |

100% Xylitol (from Birch)
European Journal of Paediatric Dentistry · 2010 · controlled clinical trial · n=90 children aged 6-12
In 90 children aged 6-12, salivary pH differed significantly between groups after 15 minutes of chewing xylitol gum versus paraffin pellets, salivary flow was higher (though not significantly) in the xylitol group, and the authors attributed the recovery of pH and lower bacterial counts to stimulated salivary flow.
100% Xylitol (from Birch)
Xylitol oral bacteria systematic review, 2025
BMC Oral Health · 2025 · systematic review · n=16 articles on mutans streptococci, 10 on plaque, 5 on caries
Across randomized and controlled clinical studies, xylitol gum significantly reduced mutans streptococci counts in 12 of 14 comparisons against sorbitol gum and reduced plaque accumulation in 6 of 10, leading the authors to position xylitol as an adjunct to toothbrushing rather than a replacement.
100% Xylitol (from Birch)
Xylitol format and dental outcomes review, 2024
European Archives of Paediatric Dentistry · 2024 · systematic review · n=15 clinical trials
Across 15 prospective randomized and controlled trials, xylitol significantly reduced caries occurrence versus no treatment or placebo polyol gum, with clinically meaningful benefit only where baseline caries levels were moderate or high, and with chewing gum working while xylitol candies generally did not.
Evidence note: Moderate, with a delivery caveat worth knowing: xylitol has a large, decades-deep clinical literature on raising salivary pH and lowering mutans streptococci counts, and essentially all of it studies xylitol chewing gum. The 2024 systematic review found candies did not reproduce the gum results, which the reviewers attribute to contact time. The evidence supports the ingredient and the contact-time mechanism; a trial of 900 mg of powder swished for 30-60 seconds remains to be done.
FAQ
Swallow or spit?
Either, per the label. Spitting keeps the xylitol where the swish is doing its work and keeps your swallowed total near zero. Swallowing adds about 900 mg per capsule, which only matters if you're using several a day plus other xylitol products.
What does the research actually show?
That xylitol raises salivary pH and shifts the oral bacterial profile. A controlled trial in 90 children measured a significant salivary pH difference after 15 minutes, and a 2025 systematic review found lower mutans streptococci counts in 12 of 14 comparisons. Most of that work used gum, and the reviews are clear that contact time is what does it - which is why the instruction here is swish for 30 to 60 seconds.
Is it dangerous for pets?
For dogs, yes. A 204-capsule bottle of pure xylitol is a real hazard in a house with a dog. Keep it closed and out of reach.
How much can I use in a day?
Do not exceed the recommended serving size. One capsule is about 900 mg if you swallow it, near zero if you spit.
What can I expect?
Customer feedback highlights a sense of increased oral hydration, support for mouth freshness and comfort, help with maintaining a balanced pH in the mouth, and a feeling of digestive readiness when used before meals. Individual experiences may vary.
Pairs well with
- Salt of Life — high-mineral, high-electrolyte sea salt with every meal
- Electrolyte Powder — if the dry mouth is really a hydration question
- Daily Biotic Capsules — the gut half of the same routine
Cautions
- We encourage responsible use. Xylitol can cause digestive upset in some individuals when consumed in excess.
- Consult your healthcare professional before use if pregnant, nursing, managing a medical condition, or considering this product for children.
- Do not exceed the recommended serving size.
- Keep away from dogs. Do not leave open capsules or loose powder where a dog can reach them.
- Contains pork-free bovine capsules.
- Store in a cool, dry place with the lid closed. Xylitol is hygroscopic and will clump in humidity. Best if used within 12 months of opening.
Lab Tested
Every product. COA on request, ~2 weeks.
Small Batch
Made in small batches, about as close to homemade as a capsule gets.
Nothing Hidden
One ingredient, plus the capsule. 900 mg of birch xylitol each.
