Is it true that dietary supplements can affect job performance and chemical test results?

Dietary supplements can indeed affect job performance and chemical test results, which makes the assertion true. Supplements may contain active ingredients that can impact physical and cognitive functions, influencing how well an individual performs in their job. For instance, some supplements may enhance energy levels, focus, or muscle recovery, potentially improving job performance in physically demanding roles. Conversely, other supplements could lead to negative side effects such as drowsiness or anxiety, affecting job efficacy.

Additionally, many dietary supplements may contain substances that could interfere with standard drug testing protocols. This can lead to false positives or detectable levels of banned substances that could violate workplace policies. The presence of these ingredients is often not fully disclosed on labels, making it difficult for individuals to know how these supplements can affect them in a professional setting.

Other options suggest limitations based on specific supplements or dosages, but such distinctions do not take into account that even commonly used supplements could have unexpected effects, especially when combined with other substances or when consumed regularly. Therefore, the broader view that supplements can affect both job performance and test results is entirely accurate.
