Histological and biochemical serum effects of
alpha-tocopherol on ischemia/reperfusion-related injuries induced in the pelvic limb of rats.
Alpha-tocopherol 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.
Alpha-tocopherol is a common form of vitamin E with the highest antioxidant activity.
Alpha-tocopherol 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.

Detection of topically applied
alpha-tocopherol in vitreous Reagents and Chemicals
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).
