Role of a Dietary Supplement in Lowering SAH in Healthy Adults With Elevated Plasma SAH and Normal Homocysteine Levels (SAH)
A Randomized, Single-Blind, Placebo-Controlled Trial for the Role of a Dietary Supplement in Lowering S-Adenosylhomocysteine (SAH) in Healthy Adults With Elevated Plasma SAH and Normal Homocysteine Levels and Identification of Participants With Elevated Plasma SAH in the General Population Using the MethylQ Score
S-adenosylhomocysteine (SAH) is the end-product of methylation reactions in the body and the precursor to homocysteine. Elevated SAH in the blood is a reflection of the dysregulation of what is known as the S-adenosylmethionine (SAM) cycle and has been associated with poor health outcomes. The SAM cycle is a series of reversible reactions necessary for the regulation of many processes in the body.
The goal of this clinical trial is to assess the ability of a dietary supplement to support healthy plasma SAH levels in individuals with high plasma SAH.
Participants in the study will attend a total of 4 clinic visits and consume study product daily for 12 weeks.

Detailed Description
Methionine, a dietary amino acid commonly found in meats, is processed by the body and yields the by-product S-adenosylhomocysteine (SAH), which then undergoes condensation with ATP to produce S-adenosylmethionine (SAM). SAM is the main methyl donor in many of the reactions that occur in the cell. These methyl reactions are well-known epigenetic mechanisms involved in DNA gene expression. When SAM donates its methyl group in a reaction, it becomes SAH which participates in a reversible reaction with homocysteine. Homocysteine is then removed through re-methylation to methionine using folate and vitamin B12. This decrease in homocysteine levels prevents the over-production of SAH, which can disrupt the methyl reactions throughout the body. Dysregulation of this pathway leads to elevated levels of SAH, which have been associated with various disease states. Therefore, an intervention which can lower SAH may ameliorate the outcomes associated with its elevation. This trial will evaluate the efficacy of a dietary supplement to lower SAH in individuals with elevated SAH and normal homocysteine. In addition, this study aims to explore the correlation between the MethylQ score (derived from 3 questionnaires) and measures of SAH level and the SAM:SAH ratio.
The test product contains alpha-GPC, creatine, and ashwagandha. Individually, these ingredients have been shown to improve levels of either SAH or homocysteine in clinical trials.
Participants will be assigned to either the test product or placebo at a 5:3 and consume study product orally for 12 weeks. Assessment measures will include methylation biomarkers, free cortisol index, mood states and MethylQ score in individuals with elevated SAH levels (≥ 20 nmol/L) and normal homocysteine (≤ 13 µmol/L).
The study will include a screening visit followed by a screening period lasting up to 90 days in duration with a remote check-in via phone call occurring between Day -40 and Day -30 (inclusive) for participants screened more than 30 days prior to the baseline visit on (Visit 2). Following the screening period, participants will attend a baseline visit on Day 1, an interim visit on Day 43 ± 3, and an end of study visit on the day after the 12-week (± 3 days) study product use (Day 85 ± 3). The study will include a total of 4 in-person visit days: a screening visit (Visit 1), a baseline visit (Visit 2), an interim visit (Visit 3), and an EOS visit (Visit 4).
