Oral Hydrate - Saliva Enzyme and pH Support - From Raw Birch
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
- No Sugar
- No Flavors
- No Fillers
- No Artificial Sweeteners
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. The authors call it an adjunct to brushing, not a replacement, and so do we.
- 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 birch xylitol per capsule. No flavors, no sweetener blend, no sugar.
- Open, swish, spit or swallow. Spitting keeps your swallowed total near zero, which is the difference between this and eating a bag of xylitol mints.
What you're getting (approximate)
The per-capsule figure is the label's; the daily figure is what four uses adds up to if you swallow every one.
| Serving | Xylitol |
|---|---|
| 1 capsule | ~900 mg |
| 4 capsules (the label's suggested times, swallowed) | ~3.6 g |
| Spat out rather than swallowed | ~0 g |
Approximate. The 900 mg fill is the label figure; 204 capsules per container. For tolerance context, a published threshold study reported non-effect levels for transitory diarrhea of 0.37 g/kg body weight in men and 0.42 g/kg in women, and a controlled trial found significantly increased watery stools at 35 g taken in a liquid. Count all the xylitol in your diet, not just this. Not a lot-specific assay; ask us for the current certificate of analysis.
How to use
- Open a capsule and tip the contents into your mouth.
- Swish for 30 to 60 seconds. Contact time is what the research is built on.
- Then either swallow or spit. Spitting keeps your daily swallowed amount near zero.
- Common times: on waking, before eating, after brushing, and before bed.
- It is an adjunct to brushing and flossing, not a substitute for either.
Sourcing & making
One ingredient: xylitol from birch, lab tested, encapsulated in USP-grade pork-free bovine capsules so it stays dry and portioned. Xylitol is hygroscopic, which is why it comes in capsules rather than a shaker jar. Made in small batches when you order.
Full ingredients
- 900mg 100% Xylitol (from Birch)
- Lab-Tested USP Grade Pork-Free Bovine Capsules
Who it's for — and who it isn't
Good fit for:
- Adults who want something to swish after brushing or between meals without sugar
- People who talk for a living and end the day with a dry mouth
- Anyone who wants a portioned, portable alternative to a bag of xylitol mints
Probably not for you if:
- You have a dog in the house and can't guarantee the bottle stays closed and out of reach. Xylitol is poisonous to dogs.
- You are sensitive to sugar alcohols. Xylitol causes digestive upset in some people, and this adds to whatever else you get in a day.
- You avoid beef or have alpha-gal sensitivity. The capsule shell is bovine gelatin.
Testing & quality
Every product is lab tested. Certificates of analysis on request, about a two-week turnaround. Every lot is tested for purity and contaminants before it's bottled.

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. FDA warns that xylitol causes rapid insulin release and dangerous drops in blood sugar in dogs within 10 to 60 minutes, sometimes delayed up to 24 hours. 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?
The label doesn't set a number. Four uses is about 3.6 g if swallowed, and near zero if spat. Published tolerance data puts the diarrhea non-effect level around 0.37-0.42 g/kg of body weight, which for most adults is well above that.
Does this replace brushing?
No. Every review we've read positions xylitol as an adjunct to toothbrushing. Brush, floss, see your dentist, and use this alongside it.
Pairs well with
- Salt of Life — trace minerals at meals, the other thing people keep on the counter
- Electrolyte Powder — if the dry mouth is really a hydration question
- Daily Biotic Capsules — the gut half of the same routine
Cautions
- Keep away from dogs. FDA warns xylitol is poisonous to dogs, triggering rapid insulin release and dangerous drops in blood sugar within 10 to 60 minutes, with effects sometimes delayed up to 24 hours. Do not leave open capsules or loose powder where a dog can reach them.
- Too much xylitol at once can loosen stools. Ease in.
- Contains a bovine gelatin capsule. Not suitable for anyone avoiding beef or with alpha-gal sensitivity.
- Store cool and dry with the lid closed. Xylitol is hygroscopic and will clump in humidity. Best 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.
