Lowering cholesterol naturally: compounds with scientific evidence

High cholesterol remains one of the leading risk factors for cardiovascular diseases, such as heart attack and stroke. However, an increasing number of scientific studies support the use of science-backed natural compounds as an effective complement to a comprehensive approach to health.

In this article, we explain how to lower cholesterol naturally, which ingredients have the strongest scientific evidence, and how to incorporate them effectively into your lifestyle.

What is cholesterol and why is it important to keep it under control?

Cholesterol is an essential molecule involved in key bodily functions, including hormone production and cell membrane structure. However, when LDL ("bad") cholesterol levels remain chronically elevated, cholesterol can accumulate in the arteries, forming plaques that restrict blood flow.

Optimizing the balance between LDL and HDL ("good") cholesterol is essential to:

  • Reduce cardiovascular risk.
  • Improve arterial health.
  • Promote healthy aging.

Natural compounds with scientific evidence for lowering cholesterol

Functional nutrition has identified several ingredients capable of influencing lipid metabolism through different mechanisms, including reducing intestinal cholesterol absorption, regulating liver metabolism, and providing antioxidant activity.

1. Plant sterols and stanols

Plant sterols occur naturally in plants and are among the most extensively studied compounds for cholesterol management. Their chemical structure is similar to cholesterol, allowing them to compete with cholesterol for absorption in the intestine when consumed in adequate amounts.

Key benefits:

  • Reduce LDL cholesterol by up to 10%.
  • Clinically proven effectiveness at approximately 2 g per day.

2. Bergamot extract

Extracts from Citrus bergamia have shown promising results in clinical studies.

Main effects:

  • Improves the lipid profile.
  • Reduces LDL cholesterol.
  • Provides antioxidant activity.

3. Soluble fiber (such as oat beta-glucan and psyllium)

Soluble fiber plays a key role in cholesterol regulation.

How it works:

  • Binds to bile acids.
  • Promotes cholesterol excretion.
  • Reduces cholesterol reabsorption.

4. Garlic

Garlic contains bioactive compounds such as allicin, which have beneficial metabolic effects.

Benefits:

  • Moderate reduction in LDL cholesterol.
  • Supports cardiovascular health.

5. Red yeast rice

This traditional ingredient, along with preparations such as Xuezhikang, contains monacolins—compounds that act similarly to certain statins, significantly reducing LDL cholesterol.

However, its use should be supervised by a healthcare professional, as it may cause side effects such as:

  • Digestive problems, including abdominal pain or stomach discomfort.
  • Liver toxicity, particularly when combined with other medications that affect liver function.

For this reason, it is essential to use red yeast rice under medical supervision, with regular monitoring of liver function and avoiding self-medication.

6. Omega-3 fatty acids and healthy fats

Omega-3 fatty acids, found in fatty fish and dietary supplements, are essential for cardiovascular health.

Effects:

  • Reduce triglyceride levels.
  • Improve the overall lipid profile.

7. Emerging compounds: berberine and black cumin

Research continues to identify new bioactive ingredients. Among them, compounds such as berberine and extracts from black cumin (Nigella sativa) seeds are being studied for their potential to influence cholesterol metabolism and blood pressure.

Although the results are promising, further high-quality clinical evidence is still required.

Innovation in functional nutrition: the role of plant polyphenols

Current research trends are increasingly focusing on more advanced and targeted bioactive compounds.

In this context, studies on polyphenol-rich plant extracts, such as Salicornia, have demonstrated:

  • Significant reductions in total cholesterol.
  • Potential protective effects on arterial health.
  • Applications in personalized nutrition.

This type of innovation positions companies such as Marisma Biomed at the forefront of biotechnology applied to cardiovascular health.

How to lower cholesterol naturally: a comprehensive approach

For these natural compounds to have a meaningful impact on cholesterol levels and arterial health, it is important to remember that they are not miracle supplements on their own, but rather part of a healthy lifestyle.

Key habits for a healthy life:

  • Eat a diet rich in fiber, vegetables, and healthy fats.
  • Reduce the consumption of ultra-processed foods and refined sugars.
  • Exercise regularly.
  • Manage stress effectively.
  • Get adequate sleep.

The combination of these lifestyle factors with the natural compounds described above creates a synergistic effect that enhances the effectiveness of nutraceuticals.

Emerging trends in the natural management of cholesterol

Research in functional nutrition and cholesterol management is advancing in several directions:

  • A better understanding of molecular mechanisms: Scientists are investigating how foods and bioactive extracts influence gene expression involved in lipid synthesis and absorption.
  • Clinically designed functional foods: New products combining plant sterols, soluble fibers, and standardized polyphenol extracts with clinically supported efficacy profiles.
  • Interaction with the gut microbiota: Research is exploring how the gut microbiome mediates the effects of these compounds on lipid metabolism.
  • Personalized nutrition: Precision nutrition tailored to individual cardiovascular risk profiles and metabolic responses, supported by biomarkers.
  • Research on innovative plant polyphenols: Our studies using polyphenol-rich Salicornia extract have demonstrated a significant reduction in total cholesterol in both preclinical models and human studies, suggesting a novel functional ingredient with the potential to naturally improve arterial health.

Conclusion: an effective, science-based strategy

Lowering cholesterol naturally is possible when scientifically supported compounds are combined with a healthy lifestyle.

Ingredients such as:

  • Plant sterols.
  • Soluble fiber.
  • Bergamot.
  • Garlic.
  • Omega-3 fatty acids.
  • Innovative extracts such as Salicornia.

can all be part of an effective strategy to improve the lipid profile and protect cardiovascular health.
