Top Five Health Benefits of Bitters

Written by Colleen Williams. Scientifically reviewed by Alexandra Sartori, MS Nutrition Science.

If you’re keen on tastes that are sweet and salty, don’t overlook – or avoid – bitterness. In herbalism, Traditional Chinese Medicine , and modern wellness science, the bitter taste holds a sacred place. It's not just a flavor—it's a function.

Bitters are derived from plants with a distinctly sharp, bitter flavor—think gentian root, wormwood, or dandelion. They’re prepared by infusing roots, bark, fruit, seeds, or leaves in alcohol (typically called “tinctures”)—and have been used for centuries in medicinal systems around the world. They’re known for one thing above all: supporting digestion and a healthy gut.

Keep reading to explore the top health benefits of bitters, the most revered bitter herbs, and how to incorporate bitters into your daily routine.

What is the science behind bitters?

Recent research confirms what herbalists have long practiced. Bitter taste receptors (known as T2Rs) are found not only in the mouth but also in the stomach, intestines, pancreas, and even lungs. When activated, they can help:

Regulate digestion and gut motility
Support respiratory defense, and
Communicate with the brain through the vagus nerve.

This gut-brain connection may be one reason why bitters are sometimes described as calming or grounding—especially when consumed as part of a mindful ritual.

Here are the top 5 health benefits of bitters

1. Improved Digestion

Bitters stimulate the taste receptors on the tongue, which signal the digestive system to increase the production of saliva. This kicks off the body’s digestive process, increasing the production of stomach acid, gastric juices, and enzymes which can improve digestion, reduce bloating, and support nutrient absorption.

2. Blood Sugar Regulation

Some bitters (bitter melon and gentian) may help balance blood sugar levels by slowing down gastric emptying, improving insulin sensitivity.

3. Liver Support and Detoxification

Many bitters (e.g., dandelion root, milk thistle, gentian) contain compounds that support liver health by encouraging and enhancing bile flow, supporting the liver’s natural detoxification process.

4. Appetite Regulation

Bitters can help regulate appetite by reducing overeating through increased feelings of fullness, but the science behind it isn’t so simple and has mixed results. Studies have reported that bitters might “participate in the control of food intake through the activation of gut–brain neural pathways.” Meaning that bitters might be able to diminish the desire to keep eating; however, a recent study from 2022 debated this conclusion: in evaluating twelve studies that measured bitters and food intake, “four of these found bitter administration decreased food intake and eight did not.”

5. Gut Health and Microbiome Support

Bitters may promote a healthy gut microbiome by reducing harmful bacteria, enhancing digestion and elimination, supporting the integrity of the gut lining.

What are the most common or revered bitter herbs?

The Cleveland Health Clinic lists the top bitter herbs as artichoke leaf, bitter melon, burdock root, dandelion, gentian root, licorice root, and wormwood. However, there are plenty more bitter herbs and roots that have been used for years throughout herbalism and Eastern Medicine.

While bitters are still common in Traditional Chinese Medicine, they haven’t been as popular in many western nations. Modern palates are dominated by sweet, salty, and umami – since bitter flavors have been bred out of vegetables to make them more palatable, we’ve lost many naturally-occuring bitter tastes. Additionally, with more solutions for indigestion, GERD, or heartburn prevalent in our pharmacies today, the natural apothecary digestives have faded from view.

But all is not lost. There is a market surge in bitters today. Craft cocktail bars have helped reintroduce bitters for flavor in both alcoholic and non-alcoholic beverages, and bitters are common in health food stores and wellness brands.

Key Takeaways

Bitters play a crucial role in supporting digestive function, liver detoxification, blood sugar regulation, and appetite control.

Whether taken before meals or as part of a wellness ritual, bitters offer a simple, natural way to support the body’s core systems.

Keep in mind: To get the full health benefits, bitters should be tasted (not swallowed in capsule form), as the bitter receptors in your mouth are key to triggering the digestive reflexes. This makes Rasāsvāda the perfect solution for bitters inclusion.
