Vitamin E, particularly in the form of alpha-tocopherol, is a critical antioxidant that helps protect cells from oxidative stress, supports cardiovascular and immune health, and prevents various conditions related to oxidative damage. Monitoring its levels through lab testing can be important for individuals with malabsorption disorders, poor dietary intake, or those at risk of oxidative stress-related diseases. Optimal vitamin E levels are essential for maintaining overall health and preventing potential complications.

Vitamin E is a family of eight related compounds, including four tocopherols and four tocotrienols. While alpha-tocopherol is the main form found in human tissues, gamma-tocopherol is the most common form in the U.S. diet, especially from soybean and corn oils. In contrast, European diets, which rely more on olive and sunflower oils, contain much less gamma-tocopherol—leading to significantly lower blood levels compared to Americans.

Vitamin E acts as a fat-soluble antioxidant, protecting cell membranes and polyunsaturated fatty acids from free radical damage. Gamma-tocopherol contributes to this defense, though it can be reduced when alpha-tocopherol is taken in high amounts through supplementation. Including multiple forms of vitamin E in the diet—through foods like nuts, seeds, and vegetable oils—supports a more complete antioxidant balance.

Vitamin E is an important antioxidant that reduces the formation of reactive oxygen species (ROS) that result from fat oxidation.

Vitamin E also regulates cell signaling, influences immune function, and inhibits coagulation.

A vitamin E test measures the amount of vitamin E in your blood. Vitamin E (also known as tocopherol or alpha-tocopherol) is a nutrient that is important for many body processes. It helps your nerves and muscles work well, prevents blood clots, and boosts the immune system. Vitamin E is a type of antioxidant, a substance that protects cells from damage.

Vitamin E, particularly its beta and gamma tocopherol components, is a highly beneficial nutrient well-regarded for its antioxidant properties and vital role in maintaining overall health. As one of the eight forms of Vitamin E, beta-gamma tocopherol stands out for its potent ability to neutralize harmful free radicals in the body, thus playing a critical role in preventing oxidative stress, a key factor in the development of chronic diseases. This form of Vitamin E is essential for immune system function, skin health, and the prevention of inflammation-related disorders. It is naturally found in a variety of foods including nuts, seeds, and vegetable oils, making it easily accessible through a balanced diet.

Vitamin K is a fat-soluble vitamin crucial for blood clotting, bone health, and cardiovascular function. Assessing Vitamin K status is complex, as there is no single gold-standard biomarker. Several biomarkers are used to evaluate Vitamin K levels, each with its own strengths and limitations.

Vitamin K1 is essential for blood clotting and bone health, and you can get it from various plant-based foods like leafy greens.

Vitamin K is a group of fat-soluble vitamins. This group of vitamins includes two natural vitamins: vitamin K1 and vitamin K2. These Vitamins are structurally similar and their name comes from the German word “klotting”.

Vitamin K1, is also known as phylloquinone.

Vitamin K assists with blood clotting, supports the K formation of bone and bone matrix, and aids in
glucose to glycogen conversion for storage in the
liver.

The primary function of vitamin K is to aid in the formation of clotting factors and bone proteins. It serves as a cofactor in the production of six proteins that regulate blood clotting, including prothrombin. In addition, it helps to form osteocalcin, a protein necessary for the mineralization of bone.

Vitamin K also aids in the formation of glucose into glycogen for storage in the liver. In addition, it promotes the prevention and reversal of arterial calcification, plague progression and lipid peroxidation. Deficiency may increase the risk of calcification of arterial walls, particularly in individuals on vitamin D supplementation (Vitamin D promotes calcium absorption). Vitamin K exists in three forms: K1, a natural form found in plants (phylloquinone); K2, which is synthesized in the intestine (menaquinone); and K3, a synthetic form that must be activated in the liver (menadione).

Vitamin K is absorbed in the upper small intestines and transported throughout the body in chylomicrons.

Vitamin K is a group of fat-soluble vitamins. This group of vitamins includes two natural vitamins: vitamin K1 and vitamin K2.

Vitamin K2 is the main storage form of Vitamin K in animals. It has several forms, referred to as menaquinones.

The nomenclature denoting vitamin K2 types will include an‘MK’to specify this is a menaquinone and the number following this denotes how many isoprenyl units are on the side chain of the molecule. The most common forms are MK-4 and MK-7.

Bacteria in the colon can convert K1 (from K plant-based foods) into vitamin K2.

Vitamin K2 is necessary to prevent arterial 2 calcification, which it does by activating matrix GLA
protein (MGP). This matrix GLA protein is present in blood vessels and inhibits soft tissue calcification.

Matrix GLA protein needs to be carboxylated to work properly and Vitamin K2-MK7 plays a major role in this carboxylation.

VLDL Cholesterol Cal is a calculated result, not a measured one — the "Cal" on your report means it was worked out by arithmetic from other numbers on the same panel. Which arithmetic depends on the laboratory: LOINC 13458-5 names both triglycerides divided by five and total cholesterol minus HDL cholesterol minus LDL cholesterol. Where the divide-by-five route is used it carries little your triglyceride result does not already contain, and above 400 mg/dL of triglycerides it is not considered accurate. Published reference ranges disagree: this page plots 5 - 40 mg/dL, MedlinePlus publishes 2 - 30 mg/dL, and Cleveland Clinic treats 30 mg/dL and above as elevated, which puts results in the thirties in contested territory rather than clearly normal or clearly high. The divisor of five is a population average; a newer method built from more than 1.3 million people replaces it with a factor ranging from about 3.1 to 11.9 depending on the rest of your lipid panel, and some laboratories use it instead. If you want to understand or change this number, the triglyceride line printed on the same report is the one to look at — rather than working backwards from the VLDL figure, which may not have come from it.

Special proteins, apoproteins, play an important role in moving lipoproteins around the body and facilitating their interactions with other cells. The most important of these are the apoB class, residing on VLDL, IDL, and LDL particles, and the apoA-I class, residing for the most part on the HDL particles.

VLDL are one of the major triglyceride-rich lipoproteins. They carry endogenous, hepatically synthesized triglycerides, largely derived from dietary carbohydrate or from plasma NEFA (=Non-Esterified Fatty Acids), and are of a large size (30–60 nm diameter).

Each VLDL particle has a single molecule of a larger apoB form, apoB100, with other apolipoproteins (apoE and apoCs) being acquired in plasma from HDL.

The levels of VLDL are not the only thing that matters. The size and chemical makeup of VLDL particles also contribute to health risks.

VLDL size is dependent on the triglyceride content, with large buoyant triglyceride-enriched VLDL being formed at times of triglyceride excess.

This is a ratio calculated by dividing very low density lipoprotein cholesterol by triglycerides.

A high ratio is linked to abnormal lipid metabolism and increased risk of CVD events.

Optimal: <0.20

Borderline: 0.20 – 0.30

Increased Risk: >0.30

The VLDL-C/TG Ratio is a specialized marker used to evaluate your cardiovascular health more accurately. VLDL stands for Very Low-Density Lipoprotein Cholesterol, which is one of the five major types of lipoproteins that transport fats and cholesterol in the body. TG stands for triglycerides, another type of fat in your blood. Both VLDL-C and TG are important because they can impact your risk of developing heart disease. The VLDL-C/TG ratio is calculated by dividing the VLDL cholesterol level by the triglyceride level. This ratio can help doctors understand more about the composition and size of the particles carrying cholesterol in your blood. Smaller, denser particles are often considered more harmful because they can more easily penetrate the lining of arteries and form plaques, which can lead to blockages. By analyzing this ratio, healthcare providers can gain insights into your lipid profile and cardiovascular risk, beyond what traditional cholesterol tests offer. A high VLDL-C/TG ratio might indicate an increased risk for cardiovascular disease and could prompt further investigation or intervention to manage this risk. Understanding this marker can be crucial in tailoring a more effective treatment plan to protect your heart health.

If your levels are borderline:

A borderline elevated VLDL-C/TG ratio means that while your levels are not in the high-risk category, they are not entirely in the clear, either. This could imply a slightly increased risk of developing conditions like heart disease, especially if accompanied by other risk factors such as high LDL cholesterol, low HDL cholesterol, hypertension, smoking, diabetes, or a family history of heart disease.

It's important to consider this marker in the context of a comprehensive lipid profile and your overall health. For some individuals, borderline elevated levels may prompt lifestyle modifications and possibly medical interventions to reduce the risk of cardiovascular disease. This might include changes in diet, increased physical activity, weight management, and possibly medication. Regular monitoring and a holistic approach to health can help manage this risk effectively. If you have borderline elevated VLDL-C/TG ratio levels, it's essential to discuss with your healthcare provider the best strategies for you to maintain or improve your cardiovascular health.
