Certificate of Analysis


  1. Hangover prevention: DHM has been shown to reduce the symptoms of a hangover, such as headache, nausea, and fatigue. It works by enhancing the metabolism of alcohol and reducing its toxic byproducts, thereby reducing the severity of hangover symptoms.
  2. Liver protection: DHM has been found to have hepatoprotective properties, meaning it helps protect the liver from damage caused by alcohol and other toxins. It can reduce inflammation and oxidative stress in the liver, promoting its overall health and function.
  3. Alcohol intoxication reduction: DHM has been shown to reduce alcohol intoxication by blocking the effects of alcohol on the brain’s GABA receptors. This can lead to a decrease in alcohol cravings and a reduced desire to consume more alcohol.
  4. Neuroprotective effects: DHM has demonstrated neuroprotective properties by reducing oxidative stress and inflammation in the brain. This may have implications for the prevention and treatment of neurodegenerative diseases such as Alzheimer’s and Parkinson’s.
  5. Anti-inflammatory effects: DHM has been found to possess anti-inflammatory properties, which can help reduce inflammation throughout the body. Chronic inflammation is associated with various health conditions, including cardiovascular disease, diabetes, and certain types of cancer.
  6. Antioxidant activity: DHM acts as an antioxidant, helping to neutralize harmful free radicals in the body. This can protect cells from oxidative damage and reduce the risk of chronic diseases associated with oxidative stress.
