Soylent and multivitamins


#21

Soylent has vitamin E in the form of dl-alpha-tocopheryl-acetate which is a synthetic form and is associated with adverse effects. (1,2) Even “natural” isolated/purified alpha-tocopherol is associated with adverse effects.

I haven’t done a full discovery on folic acid, but an increased risk of stroke is also seen with alpha-tocopherol – again only associated with alpha-tocopherol taken in its isolated form. (1, 2) When alpha-tocopherol is taken with other mixed vitamers from the vitamin E family it is associated with a reduced risk of stroke. (3,4)

The key here is to avoid single vitamers, and opt for a broad-spectrum mixture of vitamers. There are about 13 different E vitamers that can be found in plant foods (e.g., tocopherols + tocotrienols).
