A Study Investigating the Effects of Niagen™ in Healthy Adults.

Study Overview
=================
Brief Summary
-----------------
This study will evaluate the effect of repeated doses of Niagen™ on Niagen™ metabolite concentrations in blood, urine and muscle. There will be 3 doses of Niagen™ compared to a placebo. One quarter of subjects will receive the low dose of Niagen™, one quarter will receive the moderate dose of Niagen™, one quarter will receive the higher dose of Niagen™ and one quarter will reveive the placebo.

Agrees to refrain from consuming caffeine (i.e. coffee) on the days of study visits 3 to 7 (prior to the visit) Agrees to avoid taking Vitamin B3 (niacin, nicotinic acid,niacinamide) supplements or multivitamins 14 days prior to randomization and for the duration of the study period Has given voluntary, written, informed consent to participate in the study Agrees to avoid foods that contain high amounts of tryptophan and niacin and limit their ingestion of foods containing moderate amounts of tryptophan and niacin Exclusion Criteria: Women who are pregnant, breastfeeding, or planning to become pregnant during the course of the trial Alcohol use >2 standard alcoholic drinks per day History of alcohol or drug abuse within the past year Medicinal use of marijuana Diabetes (Type I or Type II) Subjects taking lipid lowering drugs History of renal and/or liver disease History of pellagra or niacin deficiency Significant or untreated medical disorders including recent myocardial ischemia or infarction, unstable angina, uncontrolled hypertension, AIDS, malignancy, and neurological disorders including epilepsy, and recent cerebrovascular disease Subjects with or who had recently experienced a traumatic injury, inflammation, infections or had undergone surgery Use of natural health products containing NR within 14 days prior to randomization and during the course of the study Unstable medical conditions as determined by the Qualified Investigator Clinically significant abnormal lab results at screening (e.g. AST and/or ALT > 2 x ULN, and/or bilirubin > 2 x ULN) will be assessed by the Medical Investigator History of or current diagnosis of any cancer (except for successfully treated basal cell carcinoma) diagnosed less than 5 years prior to screening. Subjects with cancer in full remission more than 5 years after diagnosis are acceptable Participation in a clinical research trial within 30 days prior to randomization Allergy or sensitivity to study supplement ingredients Allergy or sensitivity to lidocaine Bleeding disorder Serum creatinine ≥ 130µmol/L for males and ≥ 125µmol/L for female Individuals who are cognitively impaired and/or who are unable to give informed consent Any other condition which in the Investigator's opinion may adversely affect the subject's ability to complete the study or which may pose significant risk to the subjects
