You Don't Have a Oral Hygiene Problem. You Have a Bacteria Problem.
Your mouth contains over 700 species of bacteria. When the bad odour causing ones take over, no amount of brushing, flossing, or mouthwash can fix it because these bacteria live where your solutions can't reach
🔬 The real cause
Bad breath is caused by volatile sulfur compounds (VSCs) — toxic gases produced by harmful bacteria living on your tongue, gums, and throat. Mouthwash kills bacteria on contact… including the good ones that keep your breath fresh.
🪥 Why brushing isn't enough
Brushing cleans surfaces. Flossing cleans gaps. But neither one reaches the bacterial colonies embedded deep in your oral microbiome. That's why your breath comes back 30 minutes after brushing.
🧬 What actually works
Oral probiotics introduce clinically studied good bacteria (like BLIS K12 and M18) that colonize your mouth, crowd out the odor-causing strains, and keep your breath naturally fresh — from the inside out.
🛡️ Safe, natural, daily protection
No harsh chemicals. No alcohol-based rinses. No masking. Just a daily probiotic tablet that restores the balance your mouth was designed to have.
Real People. Real Fresh Breath. No More Hiding.
Results from people who stopped masking and started fixing.
"I was spending $40/month on specialty mouthwash and it never lasted past lunch. Two weeks on these probiotics and my husband actually said my morning breath was GONE. Not masked. Gone."
Morning BreathMouthwashVerified
"I used to pop mints constantly before meetings. Hand over my mouth when talking close. My coworker joked about it once and I was mortified. After 30 days on Rest Viva, I don't even think about it anymore."

Your Questions Answered
Everything you need to know about fixing your breath from the inside.
What is Rest Viva?
Rest Viva is a daily oral probiotic tablet containing clinically studied strains — BLIS K12 and BLIS M18 — that rebalance your oral microbiome. Instead of killing bacteria like mouthwash does (good and bad alike), Rest Viva introduces beneficial bacteria that colonize your mouth, crowd out the odor-causing strains, and support long-term oral health.
How do I take it?
Let one tablet dissolve on your tongue each night before bed, after your normal brushing and flossing routine. The probiotic strains work best overnight when saliva flow decreases and there's less competition. Do not chew — let it dissolve slowly for maximum colonization.
How long until I see results?
Most customers notice a meaningful difference within 1–2 weeks. For full microbiome rebalancing, we recommend consistent daily use for 30 days. Results continue to improve over time as the beneficial bacteria establish stronger colonies.
Is it safe? Any side effects?
Rest Viva is made with naturally occurring probiotic strains that already exist in a healthy human mouth. There are no known side effects. Our formula is free from gluten, dairy, soy, artificial colors, and preservatives. If you are pregnant, nursing, or on medication, consult your doctor before use.
Can this replace my mouthwash?
That's the goal. Most mouthwash contains alcohol that strips your mouth of ALL bacteria, creating a cycle where bad bacteria return faster and stronger. Rest Viva is designed to be a long-term replacement that addresses the root cause instead of masking symptoms. Many of our customers have stopped using mouthwash entirely.
Will this help with morning breath?
Yes — morning breath is one of the most common results people see first. The probiotics work overnight while you sleep, meaning you wake up with a naturally fresher mouth instead of that stale, sulfur-heavy taste.
What if it doesn't work for me?
We offer a full 30-day money-back guarantee. If you take Rest Viva daily for 30 days and don't notice a real improvement in your breath, email us and we'll refund you completely. No questions, no hassle.
How is this different from gut probiotics?
Gut probiotics are designed to survive stomach acid and colonize your intestines. Oral probiotics like BLIS K12 and M18 are specifically formulated to colonize your mouth, tongue, and throat — the exact places where bad breath bacteria live. They're different products for different problems.
