What Is HDL Cholesterol?

HDL Cholesterol, or high-density lipoprotein, is often called the "good" cholesterol. It helps remove excess cholesterol from the bloodstream and arteries, transporting it back to the liver for excretion. Higher HDL levels are associated with a lower risk of cardiovascular disease, stroke, and atherosclerosis.

Why You May Want to Improve It

Low HDL is linked to an increased risk of heart disease, especially when combined with high LDL or triglycerides. Improving HDL supports a healthier lipid profile and better vascular health.

• Cardiovascular Protection: HDL helps clear cholesterol buildup in arteries and reduces plaque formation.

• Anti-Inflammatory Role: HDL reduces oxidative stress and supports endothelial function.

• Metabolic Marker: Low HDL may indicate insulin resistance or metabolic syndrome risk.

How to Improve HDL Naturally

Diet

• Extra Virgin Olive Oil: Rich in polyphenols and monounsaturated fats that raise HDL and improve antioxidant function.

• Fatty Fish: Salmon, sardines, and mackerel contain omega-3s that elevate HDL and lower triglycerides.

• Nuts: Almonds, walnuts, and pistachios support higher HDL when consumed regularly and in moderation.

• Cut Refined Carbs: Reducing sugar and white flour products improves HDL and overall lipid ratios.

Lifestyle

• Regular Exercise: Aerobic activity (e.g., brisk walking, swimming) 30–45 minutes per day can significantly raise HDL.

• Quit Smoking: Smoking suppresses HDL levels. Quitting rapidly improves HDL function and levels.

• Moderate Alcohol (Optional): In small amounts, red wine or spirits may raise HDL—consult your physician before use.

Supplements

• Niacin (Vitamin B3): Can raise HDL but must be used cautiously due to side effects—only under medical supervision.

• Omega-3 Fatty Acids: Found in fish oil and algae oil; improves HDL while reducing inflammation.

• Berberine: Enhances HDL while also supporting glucose and lipid metabolism.

• Curcumin: Anti-inflammatory that supports healthy endothelial function and may modestly elevate HDL.

Medical Support

• Lipid Panel Testing: Monitor HDL, LDL, triglycerides, and particle counts to understand your cardiovascular risk profile.

• Manage Metabolic Health: Address underlying insulin resistance, obesity, or thyroid dysfunction that may lower HDL.

Normal Levels

Higher HDL is generally better, but extremely high levels (>90) may have less benefit. Always interpret results in context of other lipid markers.

When to See a Doctor

• History of cardiovascular disease or stroke

• Family history of lipid disorders

• Signs of insulin resistance or metabolic syndrome

• Low HDL on routine labs

A MitoHealth heart health panel includes HDL, LDL particle size, ApoB, triglycerides, and inflammation markers to give a complete cardiovascular risk profile.

FAQs

Is higher HDL always better?

Not necessarily. Extremely high HDL may not always be protective. Balance with LDL, ApoB, and inflammation markers is key.

Can you raise HDL quickly?

Exercise can begin improving HDL in a few weeks, while diet and supplements may show results in 8–12 weeks.

Is niacin safe for raising HDL?

Niacin can raise HDL but may cause flushing, liver strain, or glucose spikes. Use only under medical guidance.

What’s the best HDL-boosting food?

Fatty fish and extra virgin olive oil consistently improve HDL and overall heart health when consumed regularly.
