Vitamin A Palmitate: Vitamin A is used to classify a group of fat-soluble substances that all possess qualities of retinol activity and structure. Retinol is the parent of these substances which not only includes vitamin A but also various carotenes (i.e. beta-carotene). Vitamin A is essential to vision, the immune system, growth and development of the brain and bones, reproduction, and epithelial differentiation. Vitamin A is connected to the cornea and helps to prevent damage that may cause blindness. Vitamin A also displays antioxidant and anticarcinogenic activities. Animal liver provides the richest concentrations of vitamin A but high concentrations can also be found in eggs, whole milk, fish liver oils, butter and cream. Vitamin A may increase the risk of bleeding when taken with warfarin drugs; avoid this combination. People taking retinoid and tetracycline should avoid taking vitamin A as well, as toxic effects may occur.
vanillin methyl: vanillin. It is the primary component of the extract of the vanilla bean. It is used as a flavoring agent in foods, beverages, and pharmaceuticals. Because of the scarcity and expense of natural vanilla extract, there has long been interest in the synthetic preparation of its predominant component. Today, artificial vanillin is made from either the petrochemical guaiacol, or from lignin, a natural constituent of wood which is a byproduct of the paper industry. The largest single use of vanillin is as a flavoring, usually in sweet foods. The ice cream and chocolate industries together comprise 75% of the market for vanillin as a flavoring, with smaller amounts being used in confections and baked goods. Vanillin is also used in the fragrance industry, in perfumes, and to mask unpleasant odors or tastes in medicines, livestock fodder, and cleaning products.
Vitamin E acetate: Is a common vitamin supplement. Tocopheryl acetate is used as an alternative to tocopherol itself because the phenolic hydroxyl group is blocked, providing a less acidic product. It is believed that the acetate is slowly hydrolyzed once it is absorbed into the skin, regenerating tocopherol and providing protection against the sun's ultraviolet rays
