Overview

S-Adenosyl Methionine (SAM-e) is a molecule produced naturally in the body. It is involved in numerous critical biochemical reactions, including the synthesis of neurotransmitters like serotonin and dopamine. Supplementing with SAM-e has been shown to support a positive mood, promote joint comfort and mobility, and support liver health.

Key Benefits

Elevates Mood

SAM-e is involved in the synthesis of key neurotransmitters, and supplementation can have a significant antidepressant effect.

Supports Joint Health

It helps produce proteoglycans, which are essential for cartilage repair and maintenance, reducing pain and inflammation in osteoarthritis.

Promotes Liver Detoxification

SAM-e supports the liver’s primary antioxidant, glutathione, aiding in detoxification processes.
