Oral administration of N,N-Dimethylglycine (DMG), a tertiary amino acid, presumably enhances oxygen utilization by tissue and complex with free radicals. Beneficial effects are improved endurance performance and reduction fatigue in humans and animals. This pilot study reports the results over a one-year double-blind, placebo-controlled trial of DMG in 30 randomized patients with progressive multiple sclerosis. No treatment effects were found between the placebo group and the DMG group for disability, fatigue, cognitive, or gait parameters.
