From the Guidelines

Ademetionine supplements for liver health are best taken on an empty stomach, about 30 minutes before meals, to maximize absorption and minimize potential interactions with food. The typical dosage ranges from 400-1600 mg daily, often divided into multiple doses. Taking it between meals helps maximize absorption since food can interfere with how effectively your body utilizes this compound. Ademetionine works in the liver as a methyl donor that supports important biochemical processes including methylation reactions, which help with detoxification pathways and cell membrane maintenance. It also helps produce glutathione, the liver's primary antioxidant that protects liver cells from damage. For those with liver conditions like fatty liver disease, alcoholic liver disease, or hepatitis, ademetionine may help reduce inflammation and support liver regeneration. Side effects are generally mild but can include nausea, digestive discomfort, and headache. If you're taking medications, especially antidepressants, consult your healthcare provider before starting ademetionine as it can interact with certain drugs 1.

Some key points to consider when taking ademetionine supplements include:

  • Dosage: 400-1600 mg daily, divided into multiple doses
  • Timing: Take on an empty stomach, 30 minutes before meals
  • Potential benefits: Supports liver health, reduces inflammation, and promotes liver regeneration
  • Potential side effects: Nausea, digestive discomfort, headache
  • Interactions: May interact with certain medications, such as antidepressants, so consult with a healthcare provider before starting ademetionine supplements 1.

It's essential to prioritize liver health and take ademetionine supplements responsibly, considering individual health needs and potential interactions with other medications or health conditions. Always consult with a healthcare provider before starting any new supplements, especially if you have a pre-existing medical condition or are taking medications 1.

From the Research

S-Adenosylmethionine (SAMe) Role in Liver Health

  • SAMe is a natural compound implicated in the treatment of liver dysfunction, serving as a precursor for cysteine and a major physiologic defense mechanism against oxidative stress 2.
  • It acts as the main methylating agent in the liver, and its precursor, methionine, is activated by SAMe-synthetase (EC 2.5.1.6) 2.
  • Administration of SAMe has been shown to have beneficial effects in various tissues, mainly in the liver, and especially in the mitochondria 2.

Optimal Dose and Administration of SAMe

  • The most common doses of SAMe used in studies were 1000 mg or 1200 mg per day, with or without another treatment or natural supplement 3.
  • However, the optimal route of administration and long-term efficacy and safety data of SAMe in liver diseases are still needed to be assessed 3.

Timing of SAMe Intake

  • There is no specific information available on whether SAMe should be taken before or after meals.
  • However, it is known that SAMe can cause mild, transient gastrointestinal complaints as adverse events 3, so taking it with food may help alleviate these symptoms.

Safety and Efficacy of SAMe

  • SAMe has been shown to be effective in improving liver-related parameters with few adverse events, which were primarily mild and transient 3, 4.
  • However, excess SAMe can inhibit methylation via catabolism to adenine, and its safety as a supplement has been questioned 5.
