Natural vitamin E absorbs better than lab-made versions, avoiding waste from unabsorbed synthetic compounds.
Natural vitamin E shows higher bioavailability as synthetic versions waste 50% through unabsorbable molecular structures requiring elimination.
This review is from Amazon.com for product:
Solgar Vitamin E 268 mg (400 IU), 250 Mixed Softgels - Natural Antioxidant, Skin & Immune System Support - Naturally-Sourced Vitamin E - Gluten Free, Dairy Free - 250 Servings
Body does have to work so hard to digest natural vitamin E.
Only 50% of Lab made vitamins can be absorbed due to left and right entombed that occur when man-made. Your body does not have to get rid of unabsorbalr entomer.
This reduces effective strength of vitamin because 50% of substance has y be eliminated as waste.
Vitamin Basics & Tips
Vitamin E exists in eight chemical forms, but only d-alpha-tocopherol meets human requirements most effectively. Natural vitamin E (d-alpha-tocopherol) has approximately twice the bioavailability of synthetic forms (dl-alpha-tocopherol) due to differences in molecular structure. The "d" and "dl" prefixes indicate natural and synthetic origins respectively, with synthetic versions containing mirror-image molecules (stereoisomers) that humans can't effectively utilize.
This absorption discrepancy occurs because the liver preferentially recognizes and retains natural vitamin E through a special transport protein. Synthetic forms require metabolic processing to eliminate unneeded isomers, creating metabolic waste. For skincare, natural vitamin E demonstrates superior antioxidant protection against UV damage when applied topically, as shown in a 2020 Journal of Cosmetic Dermatology study.
Dietary sources like sunflower seeds and spinach provide natural vitamin E complexes with complementary phytonutrients that enhance absorption. The NIH recommends 15mg daily for adults, but synthetic supplements may require higher doses to compensate for reduced bioavailability. Always check labels for "d-alpha-tocopherol" rather than "dl-alpha-tocopherol" when selecting supplements.
