Other Name(s):

1,2-diglyceride, 1,3-diglyceride, DAG, Diacilglicerol, Diacylglycérol, Diacylglycerol Oil, Diglyceride, Diglycéride, Huile de Diacylglycérol.


Diacylglycerol is found in small amounts in plant oils. In its concentrated form, it is used to replace fats in the diet.

Diacylglycerol is used to promote weight loss and to treat high levels of certain blood fats called triglycerides.

In manufacturing, diacylglycerol is used as a stabilizer, thickener, and texturizer.

How does it work?

Diacylglycerol might work by increasing energy use and the breakdown of fat.

Uses & Effectiveness

Possibly Effective for...

  • Weight loss and reduction of body fat. Diacylglycerol, when used in place of other fats, might promote modest weight loss. Diacylglycerol is generally added to products such as muffins, crackers, soup, cookies, and granola bars.

Insufficient Evidence to Rate Effectiveness for...

More evidence is needed to rate the effectiveness of diacylglycerol for these uses.

Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, and Insufficient Evidence to Rate (detailed description of each of the ratings).

Side Effects

Diacylglycerol appears to be safe for most people. It can cause digestive tract upset, headache, acne, and rash.

Special Precautions & Warnings:

Pregnancy and breast-feeding: Not enough is known about the use of diacylglycerol during pregnancy and breast-feeding. Stay on the safe side and avoid use.


The following doses have been studied in scientific research:


  • For weight loss and reducing body fat: 10 to 45 grams of diacylglycerol per day in foods in place of other fats. Generally, each serving contains 8 to 9 grams of diacylglycerol oil, used in place of other dietary fats, in 2 to 5 servings per day.
