S-Adenosylmethionine: SAM-e Helps Support a Healthy Mood‡
Feb 09, 2022
What Is SAM-e?
SAM-e is a key compound found in every cell in the body and is essential to many processes in the body.† SAM-e is synthesized from the amino acid, methionine, which is found in protein-rich foods, along with adenosine triphosphate (ATP):
Why is SAM-e Important?
METHYLATION: SAM-e donates its methyl group to a variety of reactions, which makes SAM-e a powerful methyl donor. This is important because in SAM-e methylates the phospholipid bi-layer and helps to maintain the cell wall structure and fluidity of cell membranes. This allows for nerve-cell communication from the neurotransmitters, serotonin and dopamine. In the brain, SAM-e helps maintain the membrane coating of nerve cells and plays a role in the production of neurotransmitters that nerve cells use to communicate. This includes the conversion of norepinephrine into epinephrine and serotonin into melatonin.†1 SAM-e has shown to help support a healthy mood, as documented in a number of studies involving adults.†1-5
TRANSULFURATION: SAM-e incorporates sulfur into proteoglycans to help support joint tissue and cartilage. During this process, the amino acids cysteine and glutathione are formed.6-7
Why May SAM-e Be Beneficial?
Age and nutritional status (e.g. poor diet) can affect the amount of SAM-e your body makes. This is one reason why a mood supplement such as SAM-e supplements may be helpful in replenishing the necessary supply of SAM-e your body needs to support health and wellbeing, including your mood.†2-5 SAM-e may also be helpful as an additive therapy for those with major depressive disorder who may not be responding to traditional prescription antidepressants (Selective Serotonin Reuptake Inhibitors or SSRIs). A clinical study on patients taking 800 mg of SAM-e twice daily + an SSRI over 6 weeks showed a significant response rate and remission compared to traditional anti-depressant therapy. In fact, the beneficial effects from SAM-e were observed sooner than SSRIs taken alone.1
SAM-e also helps support joint health by providing a dietary source of sulfur, which is needed for the body to build collagen, connective tissue, and joint cartilage.†6-7
It is important to note B vitamins help support SAM-e synthesis in the body.†8 SAM-e can form methionine, however, this can only occur in the presence of adequate amounts of B vitamins, especially vitamin B12 and folic acid.
Other benefits of SAM-e:
Fast-acting: works in as little as 7-14 days when taken daily†9
Not known to have significant side effects
Not known to interact with most medications* *except Monoamine Oxidase Inhibitors (MAOIs)
Adults start by taking one tablet (400 mg) daily with water on an empty stomach. If benefits are not achieved within two weeks, a higher level of supplementation may be needed. To determine the proper level for you, gradually increase the number of tablets (maximum of 1600 mg/day) until benefits are achieved.
Who Should Take SAM-e?
Those who want to support a healthy mood† and/or joint health.
The AHRQ (Agency for Healthcare Research and Quality) report concluded that “the side effects of SAM-e seem relatively minor.”10 Mild side effects that define AHRQ have been reported from SAM-e trials in adults include: mild insomnia, lack of appetite, constipation, nausea, dry mouth, sweating, dizziness, heart palpitations and anxiety/nervousness. These effects similarly occurred among patients in the same studies who had received placebos.
SAM-e has been well-studied and is a safe, effective supplement to help support a healthy mood.10‡†
Although generally considered safe, SAM-e has not been extensively evaluated in children or pregnant or lactating women.
Use with caution in people with bipolar (manic) depression or in those having suicidal ideations. SAM-e should not be considered without consultation and monitoring with a healthcare professional.
Should I Add a Sam-e Supplement to My Daily Routine?
It’s important for patients to communicate with their healthcare professionals about any changes to their daily regimen including dietary supplements. Work together to understand personal nutrition needs as well as current dietary patterns to identify nutrient gaps. For those who are still unable to meet their nutrient needs from diet alone, it’s important to discuss the need to fill any potential nutrient gaps with dietary supplements, as a safe and effective way to ensure adequate intake of all essential nutrients.
