Systemic Wellness

Science continues to uncover the depth and complexity of the connection between oral health and the health of all major systems in the body. Duo includes purifying antioxidants and nourishing botanical extracts that promote a balanced oral microbiome – key to reducing risk of oral and systemic disease and to improving overall health outcomes.

ORIGINAL

nourish + balance the oral microbiome

Almost half of Americans suffer from gum disease, which is linked to health problems such as diabetes, heart disease, stroke, and Alzheimer's. Good mouths breed good bacteria.

ORIGINAL with nHa and antioxidants is the base for all of our tablets.

IMMUNITY

fortify defenses + reset the senses

140 million Americans are Vitamin D deficient, with higher rates for those in desk jobs and especially during winter months. No more excuses for not taking your vitamins.

IMMUNITY adds Vitamins D and B12 to our ORIGINAL ingredients.

ENERGY

like coffee without the acidity + stains

Coffee is the most consumed beverage in America, and yet it causes jitters, anxiety, tooth staining and an acidic oral environment. Enter a clean take.

ENERGY adds caffeine with L-theanine and Vitamin B12 to our ORIGINAL ingredients.

SLEEP

sleep hygiene meet oral hygiene

Almost 70 million Americans struggle with chronic sleep problems, which lead to sad days and poor overall health outcomes. Meet your new sleep routine.

SLEEP adds melatonin with l-theanine and lavender to our ORIGINAL ingredients.

the science of mucosal absorption

As part of its central role in the digestive system, the mouth is full of blood capillaries and absorbent tissue that actively extract nutrients and distribute them around the body. Many medications and supplements use this method of delivery because of its efficiency and ease.


As you brush, the functional vitamins and supplements in Duo cross the permeable membrane inside your mouth and absorb directly into your system.
