Monk fruit is a small, green gourd that resembles a melon. It’s grown in Southeast Asia. The fruit was first used by Buddhist monks in the 13th century, hence the fruit’s unusual name.

Fresh monk fruit doesn’t store well and isn’t appealing. Monk fruit is usually dried and used to make medicinal teas. Monk fruit sweeteners are made from the fruit’s extract. They may be blended with dextrose or other ingredients to balance sweetness.

Monk fruit extract is 150 to 200 times sweeter than sugar. The extract contains zero calories, zero carbohydrates, zero sodium, and zero fat. This makes it a popular sweetener alternative for manufacturers who make low-calorie products and for the consumers who eat them.

In the United States, sweeteners made from monk fruit are classified by the U.S. Food and Drug Administration (FDA) as “generally recognized as safe,” or GRAS.

What are the benefits of monk fruit?


  1. Sweeteners made with monk fruit don’t impact blood sugar levels.
  2. With zero calories, monk fruit sweeteners are a good option for people watching their weight.
  3. Unlike some artificial sweeteners, there’s no evidence to date showing that monk fruit has negative side effects.

There are several other pros to monk fruit sweeteners:

  • They’re available in liquid, granule, and powder forms.
  • They’re safe for children, pregnant women, and breast-feeding women.
  • According to a 2009 study, monk fruit gets its sweetness from antioxidant mogrosides. The study found monk fruit extract has the potential to be a low-glycemic natural sweetener.
  • A 2013 study concluded mogrosides may help reduce oxidative stress. Oxidative stress may lead to disease. Although it’s unclear how specific monk fruit sweeteners come into play, the study shows monk fruit’s potential.

What are the disadvantages of monk fruit?


  1. Monk fruit is difficult to grow and expensive to import.
  2. Monk fruit sweeteners are harder to find than other sweeteners.
  3. Not everyone is a fan of monk fruit’s fruity taste. Some people report an unpleasant aftertaste.

Other cons to monk fruit sweeteners include:

  • Some monk fruit sweeteners contain other sweeteners such as dextrose. Depending on how the ingredients are processed, this may make the end product less natural. This may also impact its nutritional profile.
  • Mogrosides may stimulate insulin secretion. This may not be helpful for people whose pancreas is already overworking to make insulin.
  • They haven’t been on the U.S. scene very long. They’re not as well studied in humans as other sweeteners.

What is stevia?

Stevia is 200 to 300 times sweeter than sugar. Commercial stevia sweeteners are made from a compound of the stevia plant, which is an herb from the Asteraceaefamily.

The use of stevia in foods is a bit confusing. The FDA hasn’t approved whole leaf or crude stevia extracts as a food additive. Despite being used for centuries as a natural sweetener, the FDA considers them unsafe. They claim literature indicates stevia in its most natural form may affect blood sugar. It may also affect reproductive, renal, and cardiovascular systems.

On the other hand, the FDA has approved specific refined stevia products as GRAS. These products are made from Rebaudioside A (Reb A), a glycoside that gives stevia its sweetness. The FDA indicates products marketed as “Stevia” are not true stevia. Instead, they contain highly purified Reb A extract that’s GRAS.

Refined stevia Reb A sweeteners (called stevia in this article) have zero calories, zero fat, and zero carbs. Some contain other sweeteners such as agave or turbinado sugar.

What are the benefits of stevia?


  1. Stevia sweeteners don’t have calories and are a good choice for people trying to lose weight.
  2. They generally don’t raise blood sugar levels, so they’re a good sugar alternative for people with diabetes.
  3. They’re available in liquid, granule, and powder forms.

The pros of stevia sweeteners are similar to monk fruit sweeteners.

What are the disadvantages of stevia?


  1. Sweeteners with stevia are more expensive than sugar and most other artificial sweeteners.
  2. It may cause side effects such as bloating, nausea, and gas.
  3. Stevia has a licorice flavor and somewhat bitter aftertaste.

Stevia has several other downsides, including:

  • It may cause allergic reaction. If you’re allergic to any plant from the Asteraceaefamily such as daisies, ragweed, chrysanthemums, and sunflowers, you shouldn’t use stevia.
  • It may be blended with higher-calorie or higher-glycemic sweeteners.
  • Most stevia products are highly refined.
