HEART HEALTH / RESEARCH REVIEW
The 'good cholesterol' plot twist
A higher HDL number does not automatically mean lower heart risk.
HDL is associated with risk, but raising HDL with a drug did not necessarily improve outcomes.
The surprising trial
In AIM-HIGH, niacin raised HDL and changed triglycerides in patients already receiving intensive statin therapy, but did not add clinical benefit over the study follow-up. That does not mean HDL biology is irrelevant; it means the number alone is not a treatment goal.
What is more actionable
Review LDL cholesterol, blood pressure, smoking, diabetes status and overall risk with a clinician. A dietary pattern rich in plants and unsaturated fats is more grounded than chasing a supplement that advertises 'good cholesterol'.
Context before conclusions
Key finding: Observational studies link higher HDL cholesterol with lower risk, but interventions that raise the HDL number do not automatically improve outcomes. LDL and overall risk remain more useful treatment targets.
Study context & limits: A biomarker can reflect health without being the lever that causes it. HDL function is more complex than one routine blood-test value.

Where the evidence stops

What should you do with this?
Do not chase an HDL target with a supplement or food claim. Emphasize physical activity, tobacco avoidance, blood-pressure care and an overall heart-supportive diet, with clinical advice for your lipid profile.
