From the Guidelines

B vitamins, particularly B1 (thiamine), B6, and B12, along with folic acid, are the most beneficial vitamins to take prior to or after a night of drinking, as they help reduce hangover symptoms and support liver function. According to the study by 1, patients with mild to moderate alcoholic hepatitis should be prescribed a high protein diet supplemented with B vitamins and folic acid. This is because alcohol depletes B vitamins during metabolism and impairs folic acid levels, which can lead to increased risk of breast cancer and other health problems, as mentioned in the study by 1.

Key Nutrients

  • B-complex supplement: Take before drinking and the morning after to help reduce hangover symptoms
  • Folic acid: Helps minimize the increased risk of breast cancer from alcohol consumption, as suggested by 1
  • Vitamin C (500-1000mg): Supports liver function and helps process alcohol's byproducts
  • Magnesium (200-400mg): Can ease muscle tension and headaches commonly experienced during hangovers
  • NAC (N-acetylcysteine, 600mg): Taken before drinking may help protect the liver by boosting glutathione production

Importance of Hydration

Staying hydrated is crucial, so consider electrolyte supplements containing potassium and sodium, as alcohol causes magnesium loss through increased urination. The liver uses these vitamins to process alcohol and its toxic byproduct acetaldehyde, so replenishing them supports your body's natural detoxification processes. For best results, take these supplements before drinking and again the morning after, alongside plenty of water.

From the Research

Vitamins and Alcohol Consumption

  • There is evidence to suggest that certain vitamins may help mitigate the effects of alcohol consumption, although the primary studies provided do not directly address the question of which vitamins are best to take prior to or after a night of drinking 2, 3, 4.
  • Vitamin B6 is involved in over 150 biochemical reactions and has been shown to have antioxidant properties and the ability to lower advanced glycation end products (AGE) levels 5.
  • A study found that higher plasma levels of folate and possibly vitamin B6 may reduce the risk of developing breast cancer, particularly among women who consume moderate amounts of alcohol 6.
  • The study also found that plasma vitamin B12 levels were inversely associated with breast cancer risk among premenopausal women, but not among postmenopausal women 6.
  • While these studies provide some insight into the potential benefits of certain vitamins, they do not specifically address the question of which vitamins to take prior to or after a night of drinking.

Limitations of Current Evidence

  • The primary studies provided do not directly address the question of which vitamins are best to take prior to or after a night of drinking 2, 3, 4.
  • More research is needed to fully understand the relationship between vitamin supplementation and alcohol consumption.
  • It is essential to consult with a healthcare professional before taking any supplements, especially if you are a heavy drinker or have a history of alcohol use disorder 2, 4.
