High Cholesterol &
The Importance Of Lowering sd-LDL

1 of the 12 leading causes of
high blood pressure, heart attacks and strokes

hdl cholesterol

The Importance Of Cholesterol

Cholesterol is a key substance your body needs to stay healthy. It helps build the walls of your cells, keeping them strong and flexible.

Cholesterol is also used to make important hormones like estrogen, testosterone, and cortisol, which control things like energy levels, stress, and reproduction. It’s essential for producing bile acids, which help your body digest and absorb fats from food.

While your liver makes all the cholesterol your body needs, you also get some from the foods you eat. Having the right amount of cholesterol is important—too much can be harmful, but without it, your body couldn’t function properly. (Medical News Today)

There Are 2 Types Of Cholesterol

Cholesterol is carried through your bloodstream by lipoproteins, which come in two main types: HDL (high-density lipoprotein) and LDL (low-density lipoprotein). HDL is often called “good” cholesterol because it helps remove excess cholesterol from the bloodstream, carrying it back to the liver for disposal, which reduces the risk of plaque buildup in arteries. LDL, on the other hand, is known as “bad” cholesterol because high levels can lead to plaque formation and increase the risk of heart disease.

Within LDL, there are two subtypes: small dense LDL (sd-LDL) and large buoyant LDL (lb-LDL). Sd-LDL particles are smaller and denser, making them more harmful as they can more easily penetrate artery walls, become oxidized, and trigger plaque buildup. In contrast, lb-LDL particles are larger and less likely to contribute to arterial damage. Understanding the balance between HDL, sd-LDL, and lb-LDL is crucial for managing cholesterol levels and reducing cardiovascular risk.

What are the effects of Low HDL (Good) Cholesterol?

When there is not enough HDL cholesterol present, excess cholesterol can accumulate in the bloodstream, leading to the formation of plaques in the arteries. These plaques can narrow or block the arteries, increasing the risk of heart attack and stroke.

Other potential effects of low HDL cholesterol include:

    • Increased risk of atherosclerosis: Atherosclerosis is the hardening and narrowing of the arteries, and is a major contributor to heart disease. Low HDL cholesterol levels can contribute to the development of atherosclerosis.
    • Increased risk of type 2 diabetes: Studies have shown that low HDL cholesterol levels are associated with an increased risk of type 2 diabetes.
  • Increased risk of metabolic syndrome: Metabolic syndrome is a group of risk factors that increase the risk of heart disease and diabetes. Low HDL cholesterol is one of the components of metabolic syndrome.

Why It's Important To Lower sd-LDL cholesterol

Understanding Small Dense LDL Cholesterol (sdLDL)

Small dense low-density lipoprotein (sdLDL) cholesterol is a subtype of LDL cholesterol characterized by its smaller size and higher density. These particles are particularly atherogenic, meaning they have a heightened propensity to promote the formation of fatty deposits within arterial walls, leading to atherosclerosis. Due to their diminutive size, sdLDL particles can more readily penetrate the endothelium, become oxidized, and contribute to plaque buildup, thereby increasing the risk of cardiovascular diseases (CVD) such as heart attacks and strokes. Medical News Today

Risk Factors and Health Implications of Elevated sdLDL

Elevated levels of sdLDL cholesterol are often associated with several metabolic disturbances, including:

  • Metabolic Syndrome: A cluster of conditions like increased blood pressure, high blood sugar, excess body fat around the waist, and abnormal cholesterol levels.

  • Type 2 Diabetes: Individuals with diabetes often exhibit higher concentrations of sdLDL, contributing to their increased CVD risk.

  • Obesity: Excess body weight, particularly visceral fat, is linked to higher sdLDL levels.

The presence of sdLDL is considered an emerging risk factor for CVD, with studies indicating that individuals with a predominance of sdLDL particles may have up to a threefold greater risk of developing heart disease compared to those with larger, more buoyant LDL particles. Medical News Today

Detection and Measurement

Standard lipid profiles do not typically differentiate between sdLDL and larger LDL particles. Advanced testing methods, such as nuclear magnetic resonance (NMR) spectroscopy, gradient gel electrophoresis, or specialized assays like the Vertical Auto Profile (VAP) test, are required to quantify sdLDL levels. However, these tests are not routinely performed and may not be readily available in all clinical settings. Medical News Today

Understanding the role of sdLDL in cardiovascular health is crucial for developing comprehensive strategies to mitigate heart disease risk. Ongoing research continues to elucidate the mechanisms by which sdLDL contributes to atherosclerosis and how targeted therapies can effectively manage its levels.

Prevention

There are several lifestyle changes that can help increase HDL and lower sd-LDL cholesterol levels, such as regular exercise, eating a healthy diet high in fruits, vegetables, and whole grains, and not smoking. However, certain supplements may also be helpful in raising HDL cholesterol levels.

Tikva has 21 nutrients that help increase HDL (Good) cholesterol and lower LDL (Bad) Cholesterol

Below are clinical trials and research on these nutrients.

1. Citrus Bergamot
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6497409 

In a study involving 237 participants, taking bergamot at doses of 500 mg or 1,000 mg daily for three months showed significant improvements in cholesterol levels. Specifically, total cholesterol decreased by 20% with 500 mg and 30.9% with 1,000 mg of bergamot. LDL (bad cholesterol) levels dropped by 23% with 500 mg and 38.6% with 1,000 mg. HDL (good cholesterol) increased by 25.9% with 500 mg and 39% with 1,000 mg.

Additionally, 32 people who previously had issues with statin side effects were given 1,500 mg of bergamot daily. After stopping statins for two months and then taking bergamot for 30 days, their total cholesterol dropped by 25% and LDL by 27.6%, without the side effects associated with statins. These findings suggest that bergamot can effectively reduce total cholesterol, LDL, and potentially triglycerides, without causing statin-related side effects https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6497409
