About Omega-9 Fatty Acids
Omega-9 is a class of monounsaturated fatty acids, dominated by oleic acid (18:1 n-9), the main fat in olive oil. Unlike omega-3 and omega-6 it is non-essential (endogenously synthesized). Dietary MUFA intake is associated with favorable cardiometabolic patterns, but that evidence is for whole-food fats (olive oil), not isolated oleic-acid supplements. Appears on labels as a profile disclosure. Grades low as a standalone supplement active.
What Omega-9 Fatty Acids supports
- Diets rich in monounsaturated fat (e.g. olive oil) track with better cardiometabolic markers, though this reflects whole foods rather than isolated oleic-acid pills
How much Omega-9 Fatty Acids to take
The RDA prevents deficiency. The effective range is what clinical trials used to actually move the outcome.
Effective
0–0
mg
No established therapeutic dose; omega-9 (chiefly oleic acid) is non-essential because the body can synthesize it. Nominal range for a fatty-acid-profile line item.
Clinical evidence
Limited clinical evidence. Non-essential MUFA class; whole-food (olive oil) data doesn't transfer to isolated supplements.
