What makes Mixed Tocopherols [Low-Alpha Type] the superior form of Vitamin E to Alpha Tocopherol for nutritional supplements?

Vitamin E is a fat-soluble vital nutrient that has potent antioxidant properties and has been shown to have a number of potential health benefits. There are eight different forms of vitamin E, which are classified based on their chemical structure. These forms include alpha-tocopherol, beta-tocopherol, gamma-tocopherol, and delta-tocopherol. Of these, alpha-tocopherol is the form most commonly found in supplements and fortified foods but all exhibit antioxidant properties. Mixed tocopherols, a form of vitamin E that contains a blend of different tocopherols (alpha, beta, delta, and gamma), are often considered to be a superior form of vitamin E due to their unique benefits.

There is a significant amount of research supporting the case that a diet rich in vitamin E, which includes mixed tocopherols and tocotrienols, is associated with a lower incidence of chronic disease. However, the use of high doses of alpha-tocopherol, either natural (d-alpha tocopherol) or synthetic (dl-alpha tocopherol), as a supplement may cause harmful imbalances on inflammatory and detoxification pathways. This is likely because the eight different isomers that make up vitamin E have unique actions that support and balance each other, while supplementation with just one form of the vitamin can lead to imbalances. Some studies using alpha-tocopherol have also produced inconsistent results, further supporting the importance of consuming a variety of vitamin E isomers. 

What are mixed tocopherols?

Vitamin E is a collective term for a group of eight related compounds, including four tocopherols (alpha, beta, delta, and gamma) and four tocotrienols (alpha, beta, delta, and gamma). Tocopherols, which are found in a variety of plant-based foods such as vegetable oils, nuts, and seeds, are the most abundant form of vitamin E in the diet. Mixed tocopherols are a blend of different tocopherols that can vary in proportions depending on the source. Alpha-tocopherol is the most well-known form of vitamin E and is often used as a supplement, but research suggests that the other tocopherols, particularly gamma-tocopherol, may also provide unique health benefits.

In addition to their antioxidant actions within LDL and HDL cholesterol, the vitamin E isomers, which have been naturally evolved to have antioxidant activity, also reside in lipid bilayers where they influence cell signalling, membrane-resident enzymes, and other membrane-dependent processes. Their functions extend beyond simply serving as chain-breaking inhibitors of lipid peroxidation.

Why are mixed tocopherols a superior form of vitamin E?

Mixed tocopherols, a form of vitamin E, are considered a superior form to alpha-tocopherol alone for several reasons. First, research has shown that mixed tocopherols are more biologically active than alpha-tocopherol alone. In a study published in the journal Free Radical Biology and Medicine, mixed tocopherols were found to be more effective at scavenging reactive oxygen species (ROS) and inhibiting lipid peroxidation than alpha-tocopherol alone. This suggests that mixed tocopherols may have a stronger antioxidant effect and better protect cells from oxidative stress.

In addition, mixed tocopherols may have a more balanced effect on the immune system compared to alpha-tocopherol. A study published in the Journal of Nutrition found that mixed tocopherols had a more balanced effect on immune function, while alpha-tocopherol had a pro-inflammatory effect. This suggests that mixed tocopherols may be more beneficial for supporting a healthy immune system.

Multiple studies have also suggested that mixed tocopherols may be more effective at reducing the risk of certain diseases. A review published in the journal Nutrients found that mixed tocopherols may be more effective at reducing the risk of cardiovascular disease, cancer, and other chronic diseases compared to alpha-tocopherol alone.

Furthermore, mixed tocopherols have demonstrated significant therapeutic potential and may be considered safer when used as a nutritional supplement. Alpha-tocopherol, especially synthetic dl-alpha tocopherol, may be pro-oxidant and can disrupt detoxification enzymes and immune function, as well as promote inflammation. Supplementation with alpha-tocopherol alone may also decrease gamma-tocopherol levels, which can increase inflammation. It is important to consider the form and dosage of vitamin E when considering supplementation.

Potential health benefits of mixed tocopherols

Mixed tocopherols, a form of vitamin E, have been shown to have a number of potential health benefits beyond their antioxidant and immune-supportive properties.

One potential benefit is their ability to support cardiovascular health. A study published in the journal Atherosclerosis found that mixed tocopherols were effective at reducing LDL cholesterol and preventing the formation of plaque in the arteries, suggesting that they may be beneficial for reducing the risk of heart disease.

Mixed tocopherols have also been shown to have anti-inflammatory properties, which may be beneficial for treating and preventing certain inflammatory conditions. A study published in the journal Molecular Nutrition & Food Research found that mixed tocopherols were effective at reducing inflammation in human cells, suggesting they may be useful for reducing inflammation in the body.

In addition, mixed tocopherols may have a protective effect against certain types of cancer. A study published in the journal Cancer Prevention Research found that mixed tocopherols were effective at reducing the proliferation of breast cancer cells, suggesting they may be beneficial for preventing the development of certain types of cancer.

Mixed tocopherols may also have a protective effect against cognitive decline and neurodegenerative diseases such as Alzheimer's disease. A study published in the journal Aging and Disease found that mixed tocopherols were effective at reducing the accumulation of amyloid-beta, a protein associated with the development of Alzheimer's disease. This suggests that mixed tocopherols may be beneficial for preventing cognitive decline and neurodegenerative diseases.

Conclusion

In conclusion, mixed tocopherols are a superior form of vitamin E due to their unique benefits, including their stronger antioxidant effect, balanced immune-supportive properties, and potential to reduce the risk of certain diseases. 

While dietary intake of vitamin E is important for maintaining adequate levels in the body, it is possible to obtain this nutrient in the biologically active and bioavailable form of mixed (low-alpha type) tocopherols with vitamin supplements. However, the best way to get the essential nutrients your body needs is to eat a variety of whole, unprocessed, fruits, vegetables, nuts, seeds, and other plant-based foods. These types of food ensure that you are getting a wide range of nutrients, which may include vitamin E, and should not be replaced by vitamin and mineral supplements alone.
