“Family is not the same as being one and the same. Ethanol and Vinegar are related, but most definitely not the same.”

Inaccurate analogy. Tocopherols and trienols are components of a complex known as Vitamin E. Tocopherols + tocotrienols = Vitamin E.

When the government and most supplement companies write "Vitamin E", they are reffering to Alpha-Tocopherol.
If you think I'm kidding, look up how many "mixed tocopherol" products there are.
People need all 8 members of this group. (I take a mixed tocopherol supplement and a separate mixed tocotrienol supplement daily.) But for 50 years, the government and industry focused on Alpha Tocopherol (or worse, synthetic Alpha Tocopherol).
