Subclinical Symptoms of B3 Niacin Deficiency

Subclinical niacin deficiencies can manifest in various ways. These include a loss of taste or experiencing a metallic or rancid taste in the mouth, a loss or change in sense of smell, facial movements or changes in shape, perceived movement or instability of the ground, fatigue, and a constant feeling of restlessness. These symptoms indicate a partial deficiency of niacin, which can be resolved by supplementing with larger amounts of niacin or niacitamide, such as 6 grams per day. Niacin is crucial for mitochondrial function, supporting energy production from food and involving longevity and DNA repair processes.
