We add approximately 400 ppm non-GMO natural mixed tocopherols which are a source of Vitamin E and acts as a natural antioxidant to help preserve the oil.
1 mg alpha = 1 alpha-tocopherol equivalent (commonly referred/indicated as a-TE)
1 mg beta = 0.5 a-TE
1 mg delta = 0.03 a-TE
1 mg gamma = 0.1 a-TE.
To convert to IU, sum all a-TE and multiply by 1.49.
Since we are adding about 0.4 milligram per gram, this only calculates to about 0.1 IU/gram of oil.
