Natural Vitmain E (d-Alpha) vs Synthetic Vitamin E (dl-Alpha)
on October 31, 2012
I like Costco products,not against any of their products, i just want to clear the difference between
Natural Vitmain E (d-Alpha) and Synthetic Vitamin E (dl-Alpha)
This particular product is made of Synthetic E. Usually we need to take more amount of synthetic form to have the same results of Natural E.
Based on the research found on this site
"This may appear to be arcane nutritional chemistry, but it is key to understanding how the body absorbs natural and synthetic supplements differently. Molecular structure determines how the body uses vitamin E. Researchers have found that natural vitamin E assimilates far better than synthetic versions. Specific binding and transport proteins produced in the liver select the natural d-alpha form of vitamin E and largely ignore all other forms.
In one experiment, Japanese researchers alternately gave natural and synthetic vitamin E to seven healthy young women. It took 300 mg synthetic vitamin E to equal the blood levels achieved by a 100-mg dose of natural vitamin E. "
So before buying anything please understand the difference and then buy.
