Ingredient
Linoleic Acid
What is Linoleic Acid?
Linoleic Acid is a polyunsaturated omega-6 fatty acid commonly found in vegetable oils such as sunflower and safflower oil. It is naturally present in certain nuts and seeds and is essential for the human body, as it cannot produce it on its own.
Linoleic Acid is often used in food products for its nutritional properties and in cosmetics for its moisturizing effect. While it is essential for maintaining healthy skin and cellular functions, excessive consumption of omega-6 fatty acids without a balance of omega-3 fatty acids could potentially lead to an increase in inflammation, but the scientific evidence on its health implications is mixed.
When you see Linoleic Acid on a label, it's often an indicator of the presence of oils derived from seeds or nuts, which aligns with the interest of maintaining essential fatty acid intake in the diet.
Commonly found in: cooking oils, cosmetic creams, dietary supplements, processed snacks, baked goods
