According to the authors, boosting GSH status beneficially upregulates the genes of VD metabolism and VDR, both of which are needed to increase the bioavailability and blood levels of 25(OH)VD and reduce inflammation levels. They also found that co-supplementation with vitamin D and L-cysteine resulted in the upregulation of vitamin D regulatory genes and boosted vitamin D levels in the blood, as well as reduced inflammation and insulin resistance each with higher success compared to supplementing with vitamin D alone

However, most studies assessing safety issues or toxicity of -tocopherol supplementation have lasted only a few weeks to a few months, and side effects associated with long-term -tocopherol supplementation have not been adequately studied
In addition, individuals who may be vitamin K deficient due to liver failure, those with a propensity to bleed (e.g., bleeding peptic ulcers), and those with inherited bleeding disorders (e.g., hemophilia) or a history of hemorrhagic stroke, should not take -tocopherol supplements without close medical supervision because of the increased risk of hemorrhage (119, 128)
