What is linoleic acid?

Linoleic acid (LA) is an essential omega-6 polyunsaturated fatty acid that the body cannot make and must get from food. It is a key component of cell membranes and supports normal skin and metabolic function.

What foods are high in linoleic acid?

Linoleic acid is abundant in many vegetable oils and is also found in nuts and seeds. Common dietary sources include oils used for cooking and salad dressings, plus foods like sunflower seeds and walnuts.

What are the main benefits of linoleic acid?

Linoleic acid helps maintain the skin’s barrier and hydration and supports normal immune and inflammatory signaling. Replacing saturated fat with polyunsaturated fats like linoleic acid can help improve blood lipid profiles in many people.

How much linoleic acid do adults typically need per day?

Typical adequate intake ranges are about 12–17 g per day for adults, depending on age and sex. Needs can vary with total calorie intake and overall dietary fat pattern.

Can you get too much linoleic acid?

Very high intakes may shift inflammatory balance in some contexts, especially if overall fat intake is unbalanced. Most people do best focusing on a varied diet that includes both omega-6 and omega-3 sources.
