DMG (Dimethylglycine) Liquid by Kirkman

INSUFFICIENT RELIABLE EVIDENCE to RATE

• Aging. Although there has been interest in using oral dimethylglycine for aging, there is insufficient reliable information about the clinical effects of dimethylglycine for this purpose.
• Attention deficit-hyperactivity disorder (ADHD). Although there has been interest in using oral dimethylglycine for ADHD, there is insufficient reliable information about the clinical effects of dimethylglycine for this purpose.
• Athletic performance. Although there has been interest in using oral dimethylglycine to improve athletic performance, there is insufficient reliable information about the clinical effects of dimethylglycine for this purpose.
• Autism spectrum disorder. It is unclear if oral dimethylglycine is beneficial in males with autism spectrum disorder. Details: A very small clinical crossover study in males aged 4-30 years shows that taking low doses of dimethylglycine daily for 1 month does not improve symptoms of autism when compared with placebo (5819).
• Cardiovascular disease (CVD). Although there has been interest in using oral dimethylglycine for CVD, including hyperlipidemia, there is insufficient reliable information about the clinical effects of dimethylglycine for these conditions.
• Cognitive function. Although there has been interest in using oral dimethylglycine for cognitive function, there is insufficient reliable information about the clinical effects of dimethylglycine for this purpose.
• Epilepsy. It is unclear if oral dimethylglycine is beneficial in patients with frequent generalized or myoclonic seizures. Details: A small clinical study in patients institutionalized with frequent generalized-onset, myoclonic, or atonic seizures shows that taking dimethylglycine 300 mg daily for 2 weeks followed by 600 mg daily for 2 weeks does not reduce seizure frequency when compared with placebo (5823).
• Multiple sclerosis (MS). It is unclear if oral dimethylglycine is beneficial in patients with progressive MS. Details: A small clinical study in patients with primary or secondary progressive MS shows that taking dimethylglycine 125 mg daily for 12 months does not improve cognition, fatigue, or motor performance when compared with placebo (108050).
• Stress. Although there has been interest in using oral dimethylglycine for stress, there is insufficient reliable information about the clinical effects of dimethylglycine for this purpose. More evidence is needed to rate dimethylglycine for these uses.

General ...Orally, no adverse effects have been reported in clinical trials in adults and children using dimethylglycine. However, a thorough evaluation of safety outcomes has not been conducted.

Gastrointestinal ...Theoretically, dimethylglycine might react with nitrites in the gastrointestinal tract to form carcinogenic substances (5827). However, research suggests that dimethylglycine does not react with nitrites and is not carcinogenic (13172).
