The natural tocopherol (vitamin E) is derived from soy, but is considered soy-free.
Soy Vitamin E is so far removed from the bean, 0.00001% of the bean (estimated), but purified such that no possible protein is carried along, so it is not allergenic. Then only 0.025% of the final algae oil has this as trace antioxidant.
It is safe for all people.
