Alternate names: Acides Gras Essentiels N-6, Acides Gras Oméga-6, Acides Gras Omégas 6, Acides Gras Polyinsaturés, Acidos Grasos Omega 6, AGE, AGPI, Huiles d'Oméga 6, N-6 Essential Fatty Acids, Omega 6 Fatty Acids, Omega 6 Oils
Background
Omega-6 fatty acids, such as gamma linolenic acid, are a family of fats found in some plant oils and seeds. They are different from omega-3 fatty acids.
Omega-6 fatty acids are found everywhere in the body. They help with the function of all cells. But too much omega-6 fatty acids can change the way cells react and have harmful effects on cells in the heart and blood vessels.
People use omega-6 fatty acids for heart disease, child development, high cholesterol, cancer, diabetes, and many other conditions, but there is no good scientific evidence to support these uses.
There are different types of omega-6 fatty acids, such as gamma linolenic acid (GLA). Also, some supplements are used as sources of omega-6 fatty acids, such as evening primrose, borage, and black currant. See separate listings for these topics.

Safety Safety definitions
When taken by mouth: Omega-6 fatty acids are commonly consumed as part of the diet in amounts between 5% and 10% of daily calories. But there isn't enough reliable information to know if omega-6 fatty acids are safe to use in larger amounts.
Children: Omega-6 fatty acids are commonly consumed as part of the diet in amounts between 5% and 10% of daily calories in children over 1 year old. But there isn't enough reliable information to know if omega-6 fatty acids are safe to use as medicine.
A lung disease that makes it harder to breathe (chronic obstructive pulmonary disease or COPD): Omega-6 fatty acids can make breathing more difficult in people with COPD. Do not use omega-6 fatty acid supplements if you have COPD.
Diabetes: High intake of omega-6 fatty acids in the diet can increase the risk of developing high blood pressure in people with diabetes. Until more is known, do not use omega-6 fatty acid supplements if you have diabetes.
High triglycerides (a type of fat): Omega-6 fatty acids can raise triglyceride levels. Do not use omega-6 fatty acid supplements if you have high triglyceride levels.
Special Precautions & Warnings:
Pregnancy and breast-feeding: Omega-6 fatty acids are commonly consumed as part of the diet in amounts between 5% and 10% of daily calories. But consuming higher amounts is possibly unsafe and might increase the risk of having a very small infant or for the child to develop eczema. There isn't enough reliable information to know if omega-6 fatty acid supplements are safe to use when pregnant or breast-feeding. Stay on the safe side and avoid use.Children: Omega-6 fatty acids are commonly consumed as part of the diet in amounts between 5% and 10% of daily calories in children over 1 year old. But there isn't enough reliable information to know if omega-6 fatty acids are safe to use as medicine.
A lung disease that makes it harder to breathe (chronic obstructive pulmonary disease or COPD): Omega-6 fatty acids can make breathing more difficult in people with COPD. Do not use omega-6 fatty acid supplements if you have COPD.
Diabetes: High intake of omega-6 fatty acids in the diet can increase the risk of developing high blood pressure in people with diabetes. Until more is known, do not use omega-6 fatty acid supplements if you have diabetes.
High triglycerides (a type of fat): Omega-6 fatty acids can raise triglyceride levels. Do not use omega-6 fatty acid supplements if you have high triglyceride levels.
Effectiveness
NatMed Pro rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, Ineffective, and Insufficient Evidence to Rate.
Possibly ineffective Effectiveness definitions
- Heart disease. Higher intake of omega-6 fatty acids in the diet doesn't reduce the risk of heart disease.
- Infant development. Adding the omega-6 fatty acid called arachidonic acid to infant formula, along with an omega-3 fatty acid called docosahexaenoic acid (DHA), doesn't seem to improve brain development, vision, or growth in infants.
- High levels of cholesterol or other fats (lipids) in the blood (hyperlipidemia). Higher intake of omega-6 fatty acids in the diet doesn't seem to lower cholesterol or triglyceride levels.
- Multiple sclerosis (MS). Taking omega-6 fatty acids does not seem to prevent the progression of MS.
