Look at your most recent blood test. Was GGT included? This is quickly becoming a proxy for toxicity and oxidative stress. However, if you think the lab reference range is helpful you’re mistaken. The reference range is helpful for the possibility of pathology such as gall bladder disease or alcoholism but useless for generalized toxicity. GGT levels within the standard range but above optimal (e.g., above 16.5-20 IU/L) have been associated with metabolic dysfunction, insulin resistance, and inc
