Brief summary

The purpose of this study is to investigate the safety, pharmacokinetic profile, and effects of nicotinamide mononucleotide (NMN-C) in healthy adults, 18-65 years of age. The effects will be studied over the course of 30 days in a repeated-dose study through the collection of blood and urine samples, and administration of surveys and questionnaires.

Interventions

Daily supplementation with NMN-C at 400 mg for 29 days in total

Exclusion criteria

* Known or suspected allergy to any of the ingredients in the investigational product or standardized meals. * Active infection, or history of infection and/or antibiotic use 2 weeks prior to the screening visit as assessed by Investigator. * Presenting, in the opinion of the Investigator, a clinically significant abnormality with regard to the clinical examination and/or clinical chemistry screening parameters. * Have a history of, or present with, cardiovascular, renal, hepatic, endocrine, gastrointestinal, or inflammatory disease, as assessed by Investigator. * Has consumed multivitamins or supplements (such as St. John's Wort) within 1 month prior to the study, or unwilling to discontinue use for the duration of the study * History of cancer in the last 5 years, or currently has cancer, as assessed by Investigator. * Has a history of, or current neurological (neurodegenerative diseases, epilepsy) or psychiatric pathology that may impact the participant's ability to comply with the requirements of the protocol, as assessed by Investigator. * Presenting with immune suppression (e.g. autoimmune disease, HIV), as assessed by Investigator. * Has undergone surgery in the last 3 months, or has surgery planned during the trial period, as assessed by Investigator. * Uses concomitant medications including natural health products (excluding contraceptives and PRN or other medications, which in the Investigator's opinion, do not affect the trial outcomes or participant safety). * Currently following a regimented or restricted diet which in the opinion of the Nutritionist and/or PI would negatively affect the study outcome or participants' ability to comply with study requirements, or has in the 3 months prior to enrollment. * Plans to change dietary habits and/or activity level during the trial period. * Frequent consumption of alcohol (\> 2 standard servings of alcohol/day on average). * History of (assessed by PI) or current tobacco use (verified by positive cotinine urinalysis) * Positive urinalysis for drugs of abuse (amphetamines, Cannabinoids, Cocaine and Opiates) * Presenting a niacin deficiency, as assessed by Nutritionist's dietary assessment at screening, and Investigator's physical examination. * Has difficulty swallowing capsules. * Inability to provide blood and/or urine samples. * Positive pregnancy test, intent to get pregnant, or breastfeeding. * Any other condition that, in the opinion of the Investigator, could impair the Investigator's ability to complete the study outcomes and participant safety.

Secondary

MeasureTime frameDescription
Changes in body weightDay 1, Day 29
ToleranceDay 1, Day 2, Day 8, Day 15, Day 22, Day 29, Day 30The number of participants with Adverse Events
Changes in Quality of lifeDay 1, Day 29the mean changes in the the generic Quality of Life Self-Assessment Questionnaire SF-36 questionnaire score (The SF-36 questionnaire is scaled from a 0 to 100. The lower the score the more disability)
Changes in Sleep qualityDay 1, Day 29the mean changes in the Sleep Quality Scale (SQS) score (SQS is providing an overall score ranging from 0 to 84, where lower scores denote a healthier sleep quality)
Change from baseline in NAD+ and NMN concentrations in whole bloodPre-dose and at 0.25, 0.5, 1, 2, 4, 8, 12 hour post-dose on Day 1NAD+ and NMN will be assessed in blood at the following time points : t=0 hours (pre-dose), t=0.25 hours, t=0.5 hours, t=1 hours, t=2 hours, t=4 hours, t=8 hours and t=12 hours after dosing
Change in blood lipid profile from baseline during the intervention periodDay 1, Day 29Total cholesterol, HDL-Cholesterol, LDL-Cholesterol, Triglyceride concentrations will be evaluated

Change from baseline in homocysteine concentrationsDay 1, Day 29homocysteine level will be evaluated in plasma
Changes in Fatigue stateDay 1, Day 29the mean changes in the Multidimensional Fatigue Inventory (MFI-20) score (MFI-20 is providing an overall score ranging from 20 to 100 (a higher score indicates a higher level of fatigue).
Change from baseline in NAD+ metabolites concentrations in plasmaPre-dose and at 0.25, 0.5, 1, 2, 4, 8, 12 hour post-dose on Day 1MeNAM and NAM will be assessed in plasma at the following time points : t=0 hours (pre-dose), t=0.25 hours, t=0.5 hours, t=1 hours, t=2 hours, t=4 hours, t=8 hours and t=12 hours after dosing
Change from baseline in NAD+ metabolites concentrations in urinePre-dose and at 0.25, 0.5, 1, 2, 4, 8, 12 hour post-dose on Day 1MeNAM and Me-2-PY will be assessed in urine at the following time points : t=0 hours (pre-dose), t=0.25 hours, t=0.5 hours, t=1 hours, t=2 hours, t=4 hours, t=8 hours and t=12 hours after dosing
