Arginine, Glycine, and the Quietest Trick in Oral Health
Two amino acids show up in the dental microbiome literature with surprisingly different evidence stories. Arginine — added to specialized toothpastes — has solid clinical data showing it shifts the oral microbiome away from cavity-causing bacteria. Glycine has interesting early evidence that's mostly happening in different parts of the body. Here's what each one actually does and how to think about adding them to a routine.
Six Foods That Actually Support Your Teeth
Most dental advice is about what to avoid. Here are six foods worth eating for your teeth and oral microbiome — separated into the ones with solid clinical evidence and the ones that show promise but where the science is thinner than you might have heard.
What HRV Actually Tells You, and Why Your Mouth Might Be Part of It
HRV is the single number on your wearable that tracks how well your nervous system is recovering. It responds to sleep, training, and stress. What most people miss is that it also responds to bacteria living on your tongue.
What Mouth Breathing Does to Your Oral Microbiome
If your mouth falls open while you sleep, your oral microbiome changes in ways that affect your teeth, your gums, your cardiovascular health, and possibly how well you sleep. The bacteria in your mouth may be able to tell you whether you are a mouth breather before a sleep study does.
The Tests Your Doctor Probably Didn't Order — and Why Cnvrg Asks for Them
A standard blood panel was designed to catch disease, not to optimize health. Here's why Cnvrg asks for hs-CRP, Lp(a), RDW, MPV, and others that rarely appear on a routine lab order — and what each one tells you that a standard CBC and CMP cannot.
Three Signals, One Story — How Cnvrg Connects Your Mouth, Blood, and Sleep
Angelica is 37. Her last physical came back normal. She doesn't feel sick. She just feels like things have gotten slightly harder. This is the exact scenario a single-panel health test misses — and what connecting three data streams together can start to reveal.
The Oral-Sleep Connection — What Your Saliva Sample Says About Your Sleep
The microbial community in your saliva is sensitive enough to register how long you slept last night, whether you have obstructive sleep apnea, and whether your sleep quality has been declining for months. The relationship runs both directions.
The Connection Between Your Mouth and Your Workout
A 2025 study found that oral nitrate-reducing capacity correlated with oxygen consumption at the ventilatory threshold at rho=0.81. That's a stronger correlation than most single biomarkers achieve with fitness outcomes. Most athletes have never heard of it.
Why Your Mouth Might Be Affecting Your Blood Sugar
A 2017 study followed 945 adults for three years. One of the stronger predictors of who developed pre-diabetes was not diet quality or waist circumference. It was whether they used antiseptic mouthwash at least twice a day. Here's the mechanism.
How Diversity Works — and Why a Monoculture Mouth Is a Problem
Think about a rainforest vs. a monoculture cornfield. Your mouth works the same way. New research following tens of thousands of people over nearly nine years found that oral diversity predicts mortality — independently of smoking, age, and chronic disease.
What Gum Disease Is Actually Doing to the Rest of Your Body
Every time you chew, bacteria from your gums enter your bloodstream. With healthy gum tissue, the numbers are small. When gum tissue is inflamed — which affects nearly half of American adults over 30 — that seal breaks down. The consequences don't stay in the mouth.
The Bacteria Behind Good Blood Pressure
In 2013, researchers gave healthy volunteers antiseptic mouthwash for one week. Systolic blood pressure climbed 2.3 mmHg. Salivary nitrite dropped 90%. They hadn't changed anything else. Here's the pathway from your tongue to your arteries.
The Oral Microbiome and Alzheimer's — What the Research Actually Shows
In 96% of Alzheimer's brain tissue samples examined, researchers found DNA from a bacterium that lives in the gum pockets of people with periodontal disease — and found its enzymes actively present, correlated with disease severity. Here's what the research actually shows.
Why Beetroot Juice Keeps Showing Up in Longevity Research
Beetroot juice has been studied in randomized controlled trials for over fifteen years. The nitrate in beets feeds a biological pathway your body depends on for cardiovascular health, exercise performance, and healthy aging.
Why Sleep Timing Matters More Than Duration
Everyone knows they should sleep more. But when you sleep — and how consistently — matters more than how long. This is not a wellness platitude. It is measurable in your blood.
How Your Mouth Affects Your Heart
Most people think of the mouth and the heart as separate systems. But there is a biological pathway connecting them that starts with bacteria living on your tongue — and it accounts for roughly half of your body's nitric oxide production.
What hs-CRP Actually Measures
If your Cnvrg blood panel shows a gray dot next to hs-CRP, or your inflammation dot is red, here is what this marker actually tells you — and why it connects to your oral health and sleep more than most people realize.
The Bacteria Behind Bad Breath — and What Else They Are Doing
If you just saw a red dot on your breath health indicator, this is not just a cosmetic issue. The bacteria driving chronic bad breath are the same ones linked to gum disease, systemic inflammation, and distant organ disease.
Your Mouthwash Might Be Working Against You
Most mouthwashes kill bacteria — the good ones and the bad ones. Here is why that matters more than you think, and what to use instead.
