Mixed tocopherols refers to a collection and general term for different forms of vitamin E, which is a fat-soluble antioxidant that helps protect cells from oxidative stress. The main types of biological activity present in mixed tocopherols include alpha, beta, gamma and delta-tocopherol. Using the crude mixed tocopherols after molecular distillation as raw material, the mixed tocopherols and tocopherol homologues were separated by ion exchange method.
It generally provides health benefits such as helping protect cells from oxidative stress, supporting the immune system, preventing cell damage, and may aid cardiovascular health and skin health.
These tocopherols can be naturally derived from vegetable oils, such as sunflower oil, soybean oil, or corn oil. Used in dietary supplements, skin care products, and food preservation.
In addition to tocopherol, we also provide complex nutrients such as folic acid, zinc, etc.
The products comply with GMP standards during the production process to ensure the quality and safety of each batch of products.
