Detox & Liver Health

ALT

ALT is a liver-specific enzyme that rises when liver cells are stressed, inflamed, or damaged. It’s one of the most sensitive markers for liver function and detox capacity. Elevated ALT may reflect poor detox, fatty liver, overtraining, or inflammation from alcohol, medications, or diet. Lower levels are generally a good sign, especially when paired with a healthy AST/ALT ratio. A key marker for anyone focused on longevity, metabolic health, or recovery.
