Which side effect is NOT associated with fatty acid dietary supplements?

Fatty acid dietary supplements, such as omega-3 and omega-6 fatty acids, are generally recognized for their health benefits, including anti-inflammatory properties and support for heart health. However, they are not typically linked to impaired liver function as a common side effect. While excessive intake of fatty acids can have various repercussions, liver impairment is not a widely documented issue associated with normal dietary supplementation of fatty acids.

In contrast, the other side effects listed, such as increased bleeding time, possible decreased immune function, and gastrointestinal upset, are more frequently noted. Increased bleeding time can occur due to the blood-thinning effects of omega-3 fatty acids, which can inhibit platelet aggregation. Similarly, potential decreased immune function may arise from high doses of omega-3 fatty acids impacting the inflammatory response. Gastrointestinal upset is also a common side effect, as supplementation can lead to symptoms such as diarrhea, nausea, and flatulence. Therefore, the lack of a direct association between fatty acid supplements and impaired liver function makes it the correct choice in this context.
