What impact does a deficiency in micronutrients have on performance?

A deficiency in micronutrients has a well-documented negative impact on both cognitive and physical performance. Micronutrients, including vitamins and minerals, play crucial roles in numerous physiological processes, and their absence can lead to impairments in energy metabolism, immune function, and overall well-being. For example, deficiencies in certain B vitamins can affect energy production and cognitive function, leading to decreased mental clarity and decision-making abilities. Additionally, a lack of minerals such as iron can result in reduced oxygen transport, compromising physical endurance and strength. Overall, the absence of these essential nutrients detracts from an individual’s ability to perform effectively both mentally and physically.
