Oleoylethanolamide (OEA) is a molecule produced in the body, usually found in the intestines. It is responsible for the feeling of satiety following meals.

OEA is sometimes included in fat burning supplement stacks. There is currently no human evidence that suggests oral supplementation of OEA is able to burn fat.

OEA acts on a receptor called Peroxisome Proliferator-Activated Receptor Alpha (PPARα). When this receptor is activated in the intestines of rats, the animals consume less food. Research on rats shows that both injections and oral intake of OEA causes a reliable reduction in the amount of food eaten.

Limited human evidence suggests that OEA may be able to aid fat loss by acting on PPARα. When this receptor is activated in fat tissue, energy expenditure increases. Further evidence is needed before oral supplementation of OEA can be recommended for weight loss.

What else is Oleoylethanolamide known as?
Note that Oleoylethanolamide is also known as:
  • OEA
  • NOPE (a precursor)
Dosage information

Research on rats has observed effects at a daily dose of 10mg/kg of bodyweight. This is roughly equivalent to the following human dosages:

  • 128.5 mg for a 150 lb person
  • 171.4 mg for a 200 lb person
  • 214.3 mg for a 250 lb person
