About Omega-6 Fatty Acids
Omega-6 is a class of polyunsaturated fatty acids, dominated dietarily by linoleic acid (18:2 n-6). Linoleic acid is essential, but intake in typical diets is already high, so supplementation is rarely indicated and there is no standalone efficacy case for adding more. Appears on labels mostly as a fatty-acid-profile disclosure (amount often 0/unlisted). Grades low because there is no clinical rationale for supplementing omega-6 in the general population.
What Omega-6 Fatty Acids supports
- Linoleic acid is an essential fatty acid needed for skin barrier and cell membranes, though deficiency is rare on a normal diet
How much Omega-6 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 supplement dose; omega-6 (chiefly linoleic acid) is abundant in the Western diet and frank deficiency is rare. Nominal range for a fatty-acid-profile line item.
Clinical evidence
Limited clinical evidence. Essential fatty-acid class; no efficacy case for supplementation in typically-fed adults.
