Generally speaking, flaxseed oil can enhance antioxidant capacity, but it should be consumed in moderation. Detailed analysis is as follows:

Flaxseed oil can help improve the body's antioxidant capacity to a certain extent, which is closely related to its various nutritional components. Flaxseed oil is an excellent source of alpha-linolenic acid (ALA), an omega-3 unsaturated fatty acid that possesses inherent antioxidant activity. ALA can reduce oxidative stress-induced cellular damage by scavenging free radicals and decreasing lipid peroxidation reactions. Secondly, flaxseed oil also contains natural antioxidant substances such as vitamin E. As a fat-soluble antioxidant, vitamin E protects cell membranes from free radical attacks and works synergistically with alpha-linolenic acid to enhance antioxidant effects. Additionally, components like phytosterols in flaxseed oil also contribute to regulating the body's oxidative balance, thereby indirectly improving the body's antioxidant capacity.

The antioxidant components in flaxseed oil are susceptible to degradation under high temperatures, light exposure, and oxygen. Therefore, high-temperature heating should be avoided during consumption. It is recommended to consume flaxseed oil by cold mixing or adding it to soups, and to store it sealed and protected from light.
