📜Ancient Use

Amla (also known as Indian gooseberry), a fruit native to India and Southeast Asia, has a long history of use in Ayurvedic medicine, dating back thousands of years. Ancient texts cite its effectiveness in treating diverse conditions, including diabetes, skin ailments, digestive complaints, and weakened immunity. As high cholesterol becomes more prevalent in industrialized nations, this article examines how amla provides a natural and safe way to support healthy cholesterol levels and cardiovascular function.

❤️Relevant Pathophysiology

Elevated low-density lipoprotein (LDL), commonly known as "bad cholesterol," is becoming increasingly prevalent worldwide. This is concerning because high LDL levels are strongly associated with atherosclerotic disease, significantly increasing the risk of heart attacks and strokes (1). The causes of elevated LDL are complex but are strongly correlated with the intake of cholesterol, saturated fats, and trans fats—dietary components that are increasingly common in industrialized nations (2).

🧈Saturated Fats

Studies have shown that saturated fats raise LDL cholesterol by inhibiting LDL receptor activity in the liver and enhancing lipoprotein production. This effect worsens as more cholesterol is consumed. Conversely, replacing saturated fats with polyunsaturated fats has been shown to reduce total and LDL cholesterol levels by either decreasing LDL production or increasing LDL clearance (3).

Common foods high in saturated fats include:

• Fatty cuts of meat (beef, pork, lamb)

• Butter

• Fried foods

• Processed meats

• Palm oil

• Cheese

Many of these foods pictured below are staples of the American diet, contributing to high LDL levels (4).

A meta-analysis of over 13,000 patients demonstrated that replacing saturated fats with polyunsaturated fats significantly reduces the risk of coronary heart disease (5). Foods rich in polyunsaturated fats include:

• Fish

• Sunflower seeds

• Walnuts

• Tofu

• Soybeans

🧁Trans Fats

Artificial trans fatty acids, produced by the partial hydrogenation of vegetable or fish oils, are widely used in food manufacturing due to their lower cost, longer shelf life, and solid consistency at room temperature. This process involves adding hydrogen atoms to liquid vegetable oil, converting it into a solid fat.

Unlike natural trans fats found in foods such as ghee, milk, and some meats, artificial trans fats are strongly associated with obesity, insulin resistance, and a significantly increased risk of cardiovascular disease (6).

Foods high in artificial trans fats include (7):

• Processed foods

• Fast food

• Margarine

• Non-dairy creamers

• Pastries

• Snack foods

  

Overconsumption of cholesterol, saturated fats, and trans fats overwhelms the body's ability to regulate cholesterol, leading to its accumulation in blood vessels as pictured below (8). This compromises blood flow to major organs like the brain and heart, increasing the risk of heart attacks and strokes.

💊Current Medical Therapy: Statins

Currently, Statins are the most effective and widely prescribed medications for lowering cholesterol levels. Statins work by competitively inhibiting hydroxymethylglutaryl-CoA (HMG-CoA) reductase, the key enzyme responsible for cholesterol synthesis in the liver. By blocking cholesterol production, the liver upregulates LDL receptors, increasing the uptake of LDL from the bloodstream.

Beyond cholesterol reduction, statins also exhibit:

• Anti-inflammatory properties

• Antioxidant effects

• Plaque-stabilizing benefits that help prevent cardiovascular events independent of LDL levels

The use of statins has been strongly associated with a reduced risk of heart attacks and strokes in patients with high cholesterol. While generally well tolerated, statins can have potential side effects, including muscle pain and elevated liver enzymes (9). There is also some evidence that statins may negatively impact Coenzyme Q₁₀ levels (10).

🍏Major Phytochemical in Amla: Quercetin

Amla contains numerous beneficial phytochemicals and is one of the richest natural sources of Vitamin C—boasting 4–5 times more than oranges. I’ll be exploring this further in a future article on the skin benefits of amla.

One of the key phytochemicals linked to amla’s cholesterol-lowering properties is quercetin, a flavonoid known for its role in cholesterol metabolism. Animal studies have shown that quercetin helps reduce cholesterol by enhancing the transfer of cholesterol-laden macrophages to bile, ultimately leading to excretion through feces (10).

Quercetin also increases the expression of ATP-binding cassette transporter G1 (ABCG1), which promotes cholesterol efflux—the crucial first step in removing cholesterol from macrophage foam cells in arterial walls. This cholesterol is then taken up by the liver and secreted into bile

Additionally, quercetin enhances the activity of cholesterol 7α-hydroxylase, an enzyme that converts cholesterol into bile acids, further aiding in cholesterol elimination (11).

Amla is also a good source of dietary fiber, which binds to bile acids in the digestive tract, promoting their excretion through stool.

👩‍🔬Clinical Trials on Amla and Cholesterol

🍏Systematic Review of Randomized Controlled Trials

A systematic review of five randomized controlled trials involving 322 patients concluded that supplementation with amla significantly reduced LDL, total cholesterol, fasting blood sugar levels, and C-reactive protein (13).

🍏 Double-Blind, Placebo-Controlled Trial (98 Patients with Dyslipidemia, 12 weeks)

• Groups: Patients received either 500 mg of amla extract or a placebo twice daily. Each 500 mg dose contained 175 mg polyphenols, 40 mg triterpenoids, 50 mg of oil, and omega-3 fatty acids (14).

• Results:

  • Total cholesterol: Reduced from an average of 231.67 mg/dL  to 177.00  mg/dL in the amla group, compared to a reduction from 225.74  mg/dL to 212.55 mg/dL in the placebo group.

  • LDL-C: Reduced from 139.96 mg/dL to 111.53  mg/dL in the amla group, while the placebo group saw a reduction from 132.15  mg/dL to 126.06 mg/dL.

  • Coenzyme Q10 (CoQ) Levels: No changes were observed in the amla group, highlighting a potential advantage over statins, which may reduce CoQ levels.

🍏 Head-to-Head Comparison: Amla vs. Simvastatin (60 Patients, 42 Days)

• Groups: 500 mg of amla daily vs. 20 mg of simvastatin (15).

• Results:

  • LDL Reduction: Amla decreased LDL by 15%, whereas simvastatin reduced LDL by 13%.

  • HDL Increase: Simvastatin increased HDL by 20%, while amla increased HDL by 15%.

  • Conclusion: Amla showed cholesterol-lowering effects comparable to simvastatin, making it a promising natural alternative.

🍏Randomized Double-Blind Controlled Study in Type 2 Diabetic Patients (80 Patients)

• Groups: Patients were given either 250 mg or 500 mg of amla twice daily or atorvastatin 10 mg once daily (16).

• Results:

  • LDL Reduction:

    • 500 mg of amla twice daily lowered LDL from 124.3 mg/dL to 92.60  mg/dL.

    • Atorvastatin 10 mg lowered LDL from 126.00 mg/dL to 78.50  mg/dL.

  • Additional Findings:

    • Hemoglobin A1c improved from an average of 7.56 mg/dL to 7.09 mg/dL in the 500 mg twice daily amla group.

Full results from the study including total cholesterol, HDL, Triglycerides, and VLDL for the amla groups vs atorvastatin are included below:

🔑Key Takeaways

1. While atorvastatin is more potent at lowering LDL, amla demonstrates significant cholesterol-lowering effects with no major side effects.

2. There appears to be a dose-dependent improvement in dyslipidemia with amla, with 500 mg twice daily showing the most benefits.

3. Amla supplementation may offer additional metabolic benefits, such as improving Hemoglobin A1c levels.

These findings highlight amla as a promising natural supplement for managing cholesterol and metabolic health.

✔️Recommendations

• ✔️The studies above clearly demonstrate amla’s ability to improve elevated cholesterol levels without notable adverse effects. The fact that amla has effects comparable to low- and moderate-intensity statins is remarkable. Unlike statins, amla does not seem to cause muscle pain, liver enzyme elevation, or reductions in coenzymeQ₁₀ levels This makes it a viable natural alternative for individuals looking to lower cholesterol without experiencing common statin-related side effects.

• ✔️Fresh amla can be difficult to find in the United States, but research shows that amla retains its cholesterol-lowering effects in powdered or capsule form.

• ✔️An ideal dose for cholesterol-lowering effects appears to be 500 mg twice a day. It is important to ensure that the capsules are third-party tested and sourced from a reliable brand. Animal studies indicate that amla is non-toxic even at high doses, suggesting that doses up to 2–3 grams per day could likely be safely tolerated (17).

• ✔️For high-risk patients, including those who have had a heart attack, stroke, or other major cardiovascular event, high-intensity statins remain the preferred treatment. Amla should be considered as an alternative only for low- to moderate-risk patients.

• ✔️It is crucial to monitor cholesterol levels regularly with a healthcare provider and to ensure that they have no objections to incorporating amla into a treatment plan.

• ✔️Along with cholesterol-lowering agents like amla or statins, a healthy diet low in cholesterol, saturated fats, and trans fats, combined with regular exercise, is critical for maintaining low cholesterol levels and reducing cardiovascular disease risk.
