Conversion factors
d-alpha-tocopherol (RRR)
→ a-TE · factor 1 · 100 mg = 100 mg a-TE
d-alpha-tocopherol acetate
→ a-TE · factor 0.91 · 100 mg = 91 mg a-TE
d-alpha-tocopherol acid succinate
→ a-TE · factor 0.81 · 100 mg = 81 mg a-TE
dl-alpha-tocopherol (all-rac)
→ a-TE · factor 0.74 · 100 mg = 74 mg a-TE
dl-alpha-tocopherol acetate
→ a-TE · factor 0.67 · 100 mg = 67 mg a-TE
d-beta-tocopherol
→ a-TE · factor 0.25 · range 0.25-0.40; use 0.25
d-gamma-tocopherol
→ a-TE · factor 0.1 · 100 mg = 10 mg a-TE
alpha-tocotrienol
→ a-TE · factor 0.25 · range 0.25-0.30; use 0.25
