Why is there such a large price range for vitamin E? Is there a difference in the type of vitamin E used by various companies?
This is a common question that, thankfully, does have a clear explanation. The vitamin E found in dietary supplements may be natural or synthetic. The natural form is listed as d-alpha-tocopherol, and the synthetic form is listed as dl-alpha-tocopherol. The natural form is better absorbed by the digestive tract and, thus, is the more desirable form. Unfortunately, it costs much more than the less desirable synthetic form which explains the drastic price differences seen with vitamin E products.
