Better Brushing, All Day Long

Support Sleep, Energy, and Immunity—One Tablet at a Time

You Brush Twice a Day—Why Not Make It Count?

Every day starts and ends with brushing. But what if that small act could do more than clean your teeth?

Modern life demands more from us: better sleep, clearer focus, and stronger defenses. Many people turn to supplements to fill those gaps—but what if your toothpaste could step up, too?

Duo’s functional toothpaste tablets—Sleep, Energy, and Immunity—go beyond cleaning to support total wellness, naturally. Built on a base of nano-Hydroxyapatite toothpaste for safe enamel remineralization, these formulas deliver gentle doses of melatonin, caffeine, and key vitamins through mucosal absorption—no swallowing needed.

This is more than oral care. It’s a simple ritual for daily renewal, backed by science, clean ingredients, and purposeful design.

Why Functional Toothpaste?

Toothpaste has traditionally had one job: clean your teeth. But the oral cavity is a prime site for nutrient uptake. That’s why Duo innovated beyond conventional formulas to help support the body in other ways—without changing your routine.

Each Duo tablet is:

• Fluoride-free toothpaste that strengthens enamel with nHA

• SLS-free toothpaste that won’t disrupt your mouth’s microbiome

• Plastic-free toothpaste, packaged to reduce waste

• Tablet toothpaste, perfect for home and travel

• Made with natural, vegan, cruelty-free ingredients

And now, with targeted actives like melatonin, caffeine, and vitamins, brushing becomes more than a chore—it becomes a ritual.

Meet the Functional Formulas

💤 Duo Sleep: Wind Down With Every Brush

A calming toothpaste for your bedtime routine.

• What it is: A nighttime toothpaste tablet with 1.5mg melatonin and L-theanine, designed to relax the body and mind while strengthening enamel.

⚡ Duo Energy: Rise and Shine

A refreshing way to start your day with clarity and clean teeth.

• What it is: A morning toothpaste tablet with 10mg of caffeine (about 1/5 a cup of coffee) and vitamin B12 to help gently energize your day.

• How it works: Caffeine and B12 are absorbed as you brush—offering a subtle, jitter-free boost.

• When to use: First thing in the morning—or before a big meeting or workout.

• Who it’s for: Anyone looking for an easy energy lift. If you're sensitive to caffeine, consider using the Original formula instead.

🛡️ Duo Immunity: Daily Defense

Brush in protection, naturally.

• What it is: A daily-use tablet containing vitamin D3 and B12, formulated to support both oral and systemic immunity.

• How it works: Through mucosal absorption, your body takes in these immune-supportive nutrients while your teeth benefit from Duo’s enamel-repairing nHA.

• When to use: Anytime—morning or night.

• Who it’s for: Anyone looking to reinforce their immune system as part of a daily ritual.

Real Questions, Real Answers

1. What is Duo Sleep?

A nano-hydroxyapatite toothpaste tablet infused with 1.5mg of melatonin and L-theanine to support bedtime relaxation and oral health.

2. Can I use Duo Sleep in the morning?

It may cause drowsiness. We recommend using only at night as part of your winding-down routine.

Unlikely—each tablet contains a low dose (10mg), about 1/5 of a cup of coffee. It’s designed for a smooth, non-jittery start.

Yes! Nutrients like D3 and B12 are absorbed via mucosal absorption, meaning they enter the bloodstream through the lining of your mouth while you brush.

5. Is Duo safe if I already take supplements?

Yes. The dosages in Duo are small and complementary. That said, always consult your doctor if you’re unsure or taking prescribed medications.

Perspective of a Dentist

“Supporting enamel with nano-hydroxyapatite is a smart, science-backed move,” says Dr. Stevie Roberts, general dentist. “But what makes Duo unique is how it adds functional wellness to oral care—without asking patients to take extra steps.”

Dr. Robert Johnson, oral surgeon, adds: “Functional toothpaste is a promising category. When done thoughtfully, like Duo’s formulas, it helps patients build healthy habits that serve the whole body, not just the mouth.”
