Oral administration is also being explored, particularly for gastrointestinal and systemic healing
Furthermore, within the trauma-exposed group, higher prefrontal GABA levels retained a marginally significant association with reduced CBF levels after excluding four potential outliers ( = 0.240, P = 0.071)
When delivered through an IV, glutathione bypasses digestion and allows your body to absorb higher, more effective levels of this essential nutrient
However, some secondary measures of nerve impairment did improve, especially in participants with higher cardiovascular risk and moderate BMI.7 Shorter-term trials have shown that 600mg/day of oral racemic ALA reduced neuropathy symptoms like burning, tingling, and numbness in as little as 35 weeks.4 20 A 2010 meta-analysis concluded that oral ALA can improve symptoms of diabetic neuropathy, but noted variability in effect sizes across trials and better results with intravenous administration.1 Despite promising results from some trials, a recent systematic review evaluating eight randomized controlled trials indicates that findings on ALA's effectiveness in treating diabetic neuropathy symptoms are inconsistent.23 While ALA proved safe and tolerable across these studies, the review concluded that definitive evidence supporting significant benefits is limited
