Annotation:
(*) Biological activity and equivalence: 1 mg all-rac-alpha-tocopherol = 0.50 mg RRR-alpha-Tocopherol = 1.1 IU Vitamin E - e.g., 960 mg/g all-rac-alpha- tocopherol is equal to 480 mg/g RRR-alpha-tocopherol and 1020 mg/g all-rac-alpha-tocopherol is equal to 510 mg/g RRR-alpha-tocopherol. (Please notice, in certain countries/regions the previous conversion factor may remain: 1.1 IU Vitamin E = 1 mg all rac-alpha-tocopherol = 0.74 mg RRR- alpha-Tocopherol).
(**) ensured by quality assurance measures and therefore tested randomly only.
