All SAM-e supplements are not created equal
During the manufacture of SAM-e, two forms are produced known as the S,S and the R,S isomers. The S,S isomer is the biologically active form in the human body, whereas the R,S form is considered to be inactive. Double Strength SAMe 400 utilizes Italian SAM-e to yield the highest available percentage of the active pure S,S form on the market. Double Strength SAMe 400 contains an average of nearly 80% of the active S,S form. Other SAM-e products contain as little as only 50% of the active form. A higher content of the active form yields a more potent product.
The molecule SAM-e itself is highly unstable. It will degrade quickly in conditions of heat, light and moisture. To increase its stability, it must be formed into a salt. It is important to note that SAM-e used for dietary supplements exists in a number of salt forms. Double Strength SAMe 400 utilizes the SAM-e tosylate disulfate salt form. This salt has been the most extensively utilized form in clinical trials of SAM-e.
Because of the unstable nature of pure SAM-e it is also highly susceptible to degradation in an acidic environment like the stomach. To be utilized effectively, it must pass through the stomach for absorption in the small intestine. For this reason, only enteric-coated formulas should be used. Double Strength SAMe 400 tablets are enteric-coated to maximize the utilization and benefit of the SAM-e by the body.
Enhances Mood and Neural Function*
SAM-e has been studied for decades now for its potential role in enhancing mood and supporting healthy neural metabolism. In a double-blind placebo trial published in 1976, 30 individuals were given either SAM-e intramuscular injections (15 mg three times daily) or placebo. Individuals were assessed for improved mood and affect. It was found that 100% of patients in the SAMe group showed significant improvements in mood, while only 30% of the placebo group showed any improvement.1 The improvement seen with SAM-e in this trial was rapid, with a response time of between 4 and 7 days.
A second Italian double-blind placebo controlled study was published in 1987. Again, individuals showing signs of decreased affect and mood were administered 200 mg SAM-e as daily intramuscular injections, or a placebo, for four weeks. Each group consisted of 20 patients, with all medial and laboratory results being normal. Rating scales were used to monitor changes and the authors found that the treatment with SAM-e was significantly superior to placebo and was very well tolerated.2
Researchers had known that SAM-e injections showed benefit in mood enhancement based on the results of multiple clinical trials. However, with injections, chronic administration is always challenging. For this reason, oral doses are superior in terms of ease of administration. Studies were conducted to assess the efficacy of oral SAM-e preparations. One such study was published in 1990.
In this double-blind placebo-controlled trial, individuals were given increasing doses of SAM-e from 200 mg to 800 mg twice daily, or placebo, over the 21 day period of the trial. In the placebo group, one of the six individuals showed an enhancement of mood of 50% according to the rating scales, whereas 6 of the 9 individuals given the oral SAM-e showed a 50% or greater improvement in mood and affect.3 It was concluded that oral SAM-e, like SAM-e injections, can significantly enhance mood without significant side effects.
Another double-blind placebo controlled trial looked at the effects of administering 1600 mg of SAM-e, or placebo, daily to 80 women aged between 45 and 59. The administration took place for 30 days, after which the women were assessed for improvements. Rating scales were administered at 10 and 30 days. SAM-e supplementation significantly enhanced mood and affect in the women compared to placebo administration.4 SAM-e was also seen to be well tolerated, as three women in the placebo group and two women in the SAM-e group complained of minor side effects which did not interfere with continuation of treatment.
