What is linoleic acid (LA)?

Linoleic acid (LA) is a type of Omega-6 fatty acid that the human body cannot synthesize and must be obtained through diet. It is a key component of cell membranes and is necessary for proper cellular function. LA is converted into other Omega-6 fatty acids in the body, including gamma-linolenic acid (GLA) and arachidonic acid (AA), which are involved in various physiological processes including inflammation and immune responses.

Who would benefit from testing linoleic acid (LA) levels?

  • Individuals with a diet low in Omega-6 fatty acids or with an unbalanced Omega-3 to Omega-6 ratio.
  • People with chronic inflammatory diseases, as Omega-6 fatty acids can influence inflammation.
  • Those experiencing symptoms of skin conditions like eczema or dry skin.
  • Individuals with hormone-related issues, as LA can impact hormonal balance.

What is the role of linoleic acid (LA) in the body?

Linoleic acid is a structural component of cell membranes, contributing to their fluidity and function. It’s involved in the synthesis of signaling molecules that regulate inflammation, immunity, and platelet aggregation. Proper levels of LA are crucial for maintaining skin barrier function and overall skin health. It also plays a role in reproductive health and normal growth and development.

What are the symptoms of linoleic acid (LA) deficiency?

  • Dry, scaly, or itchy skin.
  • Increased susceptibility to skin infections.
  • Hair loss or poor hair quality.
