Conjugated Linoleic Acid FAQ

Conjugated linoleic acid is a fatty acid that naturally occurs in the body. It is used by body builders for weight loss. It is classified in the omega group of fatty acids and is considered to be a healthy form of fat similar to the omega-3 fatty acids found in fish. Fatty acids help the body distribute healthy vitamins such as A, K, E and D within the body. Fish oils, vegetable oils and sunflower oils are considered healthy sources for conjugated linoleic acids.

  1. How Does It Work?

    • Conjugated linoleic acid (CLA) works by reducing fat deposits throughout the body. Additionally, it is thought that conjugated linoleic acid improves the immune system, helping fight off bacteria, viruses and foreign bodies.

    What Does It Affect?

    • CLA is thought to be effective in weight loss and in reducing obesity. Additionally, it is thought to help reduce the risks of getting colon and rectal cancer in women. However, it is not known if taking CLA in the form of supplements is an effective method of protecting against colon and rectal cancer.

    Does It Prevent Breast Cancer?

    • Initial studies of conjugated linoleic acid and breast cancer indicate that it may play a role in preventing breast cancer in post-menopausal women. One of the excellent sources for CLA that has been associated with breast cancer prevention is the consumption of cheese, which may provide significant protection from the cancer.

    Are There Side Effects?

    • It is thought that eating foods that are high in CLAs does not provide any specific side effects. However, taking CLA as a supplement or in medically high doses, which are higher than the amounts found in foods, may result in stomach upset, diarrhea, exhaustion or fatigue.

    Can Anyone Take It?

    • Individuals with metabolic conditions should avoid taking CLA or eating excessive amounts of foods high in conjugated linoleic acid. There is some evidence that doing so can make conditions such as diabetes worse. Additionally, insufficient evidence exists about how CLA affects women who are pregnant or who may be breast feeding. As a result, it is recommended that these women avoid eating foods high in CLAs.

    Are There Interactions with Medications?

    • Currently, no evidence exists for negative interactions with medications in individuals who eat diets high in conjugated linoleic acid or take CLA supplements.

    What's the Right Dosage?

    • For individuals who are attempting to lose weight, the recommended dosing is 1.8 to 7 grams per day of foods high in conjugated linoleic acid. There is no evidence that eating amounts in the range of 3.4 grams per day or higher has any substantial additional benefit in weight loss.
