What natural supplements can help lower triglycerides and cholesterol levels?

Natural Supplements for Lowering Triglycerides and Cholesterol

Omega-3 fatty acids (fish oil) at doses of 3-4 g/day are the most effective natural supplements for lowering triglycerides, while plant sterols/stanols at 2-3 g/day are most effective for lowering LDL cholesterol. 1, 2

Omega-3 Fatty Acids for Triglyceride Reduction

• Dosage and Effectiveness:

  • 3-4 g/day can reduce plasma triglyceride levels by 20-30%, especially in patients with hypertriglyceridemia 1, 2
  • Lower doses (850 mg-2.9 g/day) have shown beneficial effects for cardiovascular health but less impact on triglycerides 1
  • Prescription omega-3 supplements are preferred over OTC supplements due to consistent quality, standardized EPA and DHA content 2

• Important Considerations:

  • May increase LDL cholesterol in some individuals with hypertriglyceridemia - monitor LDL levels regularly 1, 2
  • Most effective when combined with dietary modifications 2, 3
  • High-quality evidence supports both triglyceride reduction and cardiovascular benefit 3, 4

Plant Sterols/Stanols for Cholesterol Reduction

• Dosage and Effectiveness:

  • 2-3 g/day can decrease total and LDL cholesterol by 9-20% 1, 2
  • Available in specially formulated foods and supplements 1
  • Minimal effect on HDL cholesterol or triglycerides 1
  • Higher doses (>3 g/day) provide no additional benefit 1

• Mechanism of Action:

  • Compete with cholesterol for absorption in the intestine 1
  • Individual response varies considerably 1

• Caution:

  • May decrease plasma levels of fat-soluble vitamins (carotenes, vitamin E) 1
  • Best reserved for adults requiring cholesterol reduction 1

Soy Protein for Cholesterol Reduction

• Dosage and Effectiveness:

  • 20-50 g/day can significantly reduce LDL cholesterol 1
  • Most effective in individuals with higher baseline cholesterol levels (≥240 mg/dL) 1
  • FDA approved health claim for 25 g soy protein daily (6.25 g per serving) 1

• Important Considerations:

  • Cholesterol reduction may require the presence of isoflavones 1
  • Some commercial soy products have isoflavones removed through ethanol washing 1
  • Particularly recommended for high-risk populations with elevated total and LDL cholesterol 1

Soluble Fiber

• Evidence:
  • Psyllium fiber supplements can help lower cholesterol 5
  • The American Heart Association recommends increasing fiber intake through diet rather than supplements 1, 2
  • Aim for 10-25 g/day of viscous (soluble) fiber 2

Other Supplements with Some Evidence

• Red Yeast Rice:

  • Contains naturally occurring statins that can lower LDL cholesterol 6, 4, 7
  • Quality control issues affect safety and efficacy 6, 7

• Green Tea:

  • Some evidence for modest LDL cholesterol reduction 8, 4
  • Results are inconsistent across studies 7

• Berberine:

  • Limited evidence for lipid-lowering effects 8, 7
  • May provide some benefit in specific patient groups 8

Dietary Approach for Maximum Benefit

For best results, combine supplements with these dietary modifications:

• Reduce saturated fat to <7% of total calories 2
• Limit dietary cholesterol to <200 mg/day 2
• Reduce trans fatty acids to <1% of total calories 2
• Increase intake of fruits, vegetables, whole grains, and fatty fish 3
• Consider Mediterranean diet pattern for overall cardiovascular benefit 3

Monitoring and Precautions

• Regular lipid panel monitoring is essential when using supplements
• Inform healthcare provider about all supplements being taken
• Supplements should not replace prescribed medications without medical consultation
• Individual response to supplements varies significantly
• Quality and potency of supplements can vary between manufacturers
