HDL (high-density lipoprotein) is primarily known for its role in cardiovascular health, but it also has anti-inflammatory and antioxidant properties. These could theoretically influence allergic responses, as allergies involve inflammatory processes. However, current evidence is limited to mechanistic studies and animal models suggesting HDL may modulate mast cell activity and reduce allergic inflammation. There are no strong human trials showing that raising HDL levels directly helps with allergies. Therefore, while HDL's anti-inflammatory effects are plausible, they are not a proven treatment for allergies. Individuals with allergies should rely on established therapies and consult a healthcare professional before attempting to modify HDL levels for this purpose.
