HDL-Cholesterin

High-Density Lipoprotein Cholesterol (HDL-C) is a type of cholesterol carried by high-density lipoproteins in the blood. It is often referred to as 'good' cholesterol because it helps transport cholesterol from other parts of the body back to the liver, where it can be processed and excreted. This process is crucial for maintaining lipid balance and preventing cholesterol accumulation in blood vessels. Clinically, HDL-C is important as it is inversely associated with the risk of atherosclerotic cardiovascular diseases (ASCVD), including coronary artery disease, peripheral vascular disease, and cerebrovascular disease. Low levels of HDL-C are linked to an increased risk of these conditions, while higher levels are generally protective. Additionally, researchers have found that HDL-C levels may also be inversely related to cancer incidence and progression, although the mechanisms are not fully understood. For athletes and biohackers, maintaining optimal HDL-C levels is important for cardiovascular health and longevity. HDL-C is involved in anti-inflammatory and antioxidant processes, which can support recovery and performance. However, it is important to note that HDL-C levels can be influenced by factors such as genetics, diet, physical activity, and certain medications. Fasting is not required for HDL-C testing, but levels can be affected by recent intense exercise or acute illness, which should be considered when interpreting results.
