S-Adenosyl-L-Methionine (SAMe) has several critical physiological functions and is the common thread between three key metabolic pathways. Well-recognized as a unique methyl donor for more than 100 biological reactions, including DNA methylation. It also links methylation to polyamine synthesis (necessary for cell survival and growth) and transsulfuration, which is responsible for cysteine production, the rate-limiting factor in glutathione synthesis.2,3 Its unique positioning within these intersecting pathways explain its role as a regulator of redox status, cellular metabolism, proliferation, and apoptosis.4,5
Clinically, it has proven beneficial for a number of conditions, most notably osteoarthritis, fibromyalgia, neurodegenerative disease, depression, and liver disease.6,7 For patients with major depressive disorder, SAMe has been shown to be effective not only when compared to standard antidepressants, but also for selective serotonin reuptake inhibitor (SSRI) non-responders.8,9 It has also been shown to reduce the incidence of sexual dysfunction which commonly accompanies treatment with SSRI/SNRI therapy.10 SAMe has also shown efficacy for osteoarthritis comparable to NSAIDs, including celecoxib.11,12 Quite importantly, it is likely via increases in cartilage formation, glutathione production, DNA methylation, and gene expression which contribute to its efficacy, a stark contrast from pharmaceutical analgesics.13 Research also suggests benefit for neurodegenerative disease, and potentially for improving endothelial function.14-17
|Each Tablet Contains:|
|S-Adenosyl-L-Methionine (SAMe)||200 mg|
Microcrystalline cellulose, mannitol, enteric coating (methacrylic acid copolymer, talc, triethyl citrate, glyceryl palmitostearate, silica, titanium dioxide, medium chain triglycerides, yellow iron oxide), glyceryl behenate, vegetable grade magnesium stearate (lubricant), silica, sodium starch glycolate.
Contains no artificial colours, preservatives, or sweeteners; no dairy, sugar, wheat, gluten, soy, corn, egg, fish, shellfish, animal products, salt, tree nuts, or GMOs. Suitable for vegetarians/vegans. Sealed for your protection. Do not use if seal is broken. For freshness, store in a cool, dry place.
Recommended Adult Dose: SAMe should always be taken on an empty stomach. For mood balance: 1–4 tablets 2 times per day or as directed by a health care practitioner. For osteoarthritic pain: 1–3 tablets 2 times per day or as directed by a health care practitioner.
Do not exceed a total of 8 tablets per day. SAMe must be taken for a minimum of 2 weeks, at which time effects should be observed.
If you are taking antidepressants, hepatotoxic drugs or monoamine oxidase (MAO) inhibitors, consult a health care practitioner prior to taking SAMe in place of or in addition to those medications. Not recommended for use in children. Do not use if you are pregnant or breastfeeding. Do not take at night as SAMe may cause anxiety, restlessness and insomnia. People with bipolar disorder (manic-depressive illness) should not use SAMe unless under medical supervision. Possible side effects are: mild gastrointestinal upsets (such as stomach pain, nausea, diarrhea, flatulence), anxiety, hyperactive muscle movement, insomnia and hypomania. When these side effects occur they often diminish with time or resolve with lower doses or cessation of use. There are no documented cases of allergies to SAMe. Keep out of reach of children.
Deficiency of vitamins B6, B12, and other methyl donors may exacerbate SAMe deficiency. Theoretically, may have additive serotonergic effects when used with antidepressants, but when used simultaneously, no increase in adverse effects were noted compared to placebo.8
