Introduction
Slightly low levels of aspartate aminotransferase (AST) generally have no clinical significance and are considered normal, posing no harm. AST levels are related to liver function. A mild decrease in AST is common and typically results from the diffusion of enzymes from inside cells to the outside; it does not cause any damage to the body. It is advisable to maintain a light diet, avoid smoking and alcohol, refrain from staying up late, and prevent excessive fatigue.

AST levels are related to liver function. Low AST is a common occurrence, resulting from intracellular diffusion into the extracellular space, and does not cause harm. The normal reference range for AST is 0–40 U/L, and lower-than-average AST levels are quite normal, primarily due to dietary habits and individual constitution.
If recent diet has been low in protein, this may lead to decreased AST levels; it is advisable to increase intake of protein-rich foods. Low AST levels may also result from reduced immune function, infections, or autoimmune disorders, but typically do not require specific treatment.
AST is mainly distributed in tissues and cells such as the heart muscle, liver, and skeletal muscle. Normally, only small amounts are present in the bloodstream. However, when these tissues are damaged, AST is released into the blood, increasing its concentration. Elevated AST levels may indicate liver disease and warrant prompt medical evaluation.
It is recommended to maintain a light diet, avoid smoking and alcohol, refrain from staying up late, and prevent excessive fatigue.
