Histological and biochemical serum effects of alpha-tocopherol
on ischemia/reperfusion-related injuries induced in the pelvic limb of rats.
supplementation significantly decreased serum ALT in broilers under high temperature (Shah et al., 2016), glucose (Habibian et al., 2014) and increases serum protein (Zia ur Rehman et al., 2017).
Serum retinol, alpha-tocopherol
, and lipid peroxide concentrations in low-income Indian pregnant mothers.
As an antioxidant, gamma-tocopherol is better than alpha-tocopherol
. However, in humans, levels of alpha-tocopherol
are about five times higher than gamma levels.
The mean serum concentration of alpha-tocopherol
decreased significantly from baseline to 30 hours, while the concentration of its main metabolite (alpha-CEHC) increased significantly.
is a common form of vitamin E with the highest antioxidant activity.
is the best known vitamin E, and gamma-tocopherol is a potent antioxidant.
(9,15) Vitamin E is generally used in l%-5% concentrations alpha-tocopherol
or tocopherol acetate in over-the-counter products.
Effect of alpha-tocopherol
treatment on activity of frozen thawed boar spermatozoa.
Editor's Note: "We propose that for many Americans, especially those relying exclusively upon food sources, that serum alpha-tocopherol
concentrations may not be adequate," Dr.
Cook-Mills had done previous allergy research in mice showing alpha-tocopherol
decreased lung inflammation, protecting healthy lung function and gamma-tocopherol increased lung inflammation and airway hyperresponsiveness, a characteristic of asthma.

Indeed the few studies, which have reported on the tocopherol concentration in adzuki beans all reported negligible concentrations of alpha-tocopherol
and beta-tocopherol (Yoshida et al., 2008).
