One of the questions we often get asked is difference between the 2 Vitamin E liquids we sell and which one is better. We sell both Natural Vitamin E 50% Mixed Tocopherols and Synthetic DL Alpha Tocopheryl Acetate. So what is the difference? To really simplify and avoid all the science, it’s all about Tocopherols.
Tocopherols are a group of compounds that make up the various Vitamin Es. The Synthetic option is made in a lab and contains Alpha-tocoperol only. Alpha-tocopherol is chosen because it is the one most abundantly found in human tissue and the only one that can be used to treat Vitamin E deficiency. DL Alpha tocopheryl acetate is more chemically stable and less susceptible to environmental factors such as heat, light and air, so good for increasing shelf-life and helping to prevent rancidity in oil based products. Studies have also shown it to be effective in reducing skin damage from UV exposure when added to face products and make-up.
The natural option however, contains a 50% mix of Tocopherols d-alpha, d-beta, d-gamma and d-delta that have been distilled from soybean oil and suspended in sunflower oil. Although you may therefore think it is less potent, the opposite is actually true. Because it is natural and lacks the acetate component, it has much higher bioavailability, meaning it is anywhere between 2-5 times more efficiently absorbed by the body. When articles are written about the numerous benefits of Vitamin E, it is generally the natural form they are referring to and while alpha-tocopherol seems to be the dominant in the human body, it is important not to overlook the potential importance of all the others.
Basically put, the choice is yours. But if it is shelf-life and stability you are looking for with some Vitamin E benefits, then synthetic is fine. But if you are looking to enrich your products with all the benefits Vitamin E has to offer then we recommend heading for the natural one. We hope this helps.
