I want to dispense a smaller dose of the tocopherol oil. Is it possible to open the top and use a dropper? What type of container does this product come in? I am concerned about plastic leaching. You can dispense from the 1-oz bottle using the pump attached – 1/4 teaspoon equals 1 capsule (400 I.U. of alpha-tocopherol + gamma, beta and delta). You can take the pump off and pour or even use an eye dropper if you wish. We recommend not taking the pump off unless you plan to use the product up with a few months due to the possibility of oxidation. Leaving the pump on protects the product from the air. The container is white opaque glass – we use glass for the very reason you are concerned with.
