简要总结
Nicotinamide adenine dinucleotide (NAD) is a coenzyme playing a central role in human metabolic pathways. A recognized approach to increase NAD level is through oral supplementation of its precursors promoting NAD synthesis in vivo. NAD precursors exist in multiple forms. However, it is unclear how the various precursors compare in their ability to increase NAD levels in human blood. The purpose of this study is to compare the effect of 3 NAD precursors on whole blood NAD metabolome.

入选标准
- •Healthy male and female aged 18-50 years, inclusive, at enrolment
- •Body mass index (BMI) between 18.5 to 27.0 kg/m².
- •Able to understand and to sign a written informed consent prior to study enrolment.
- •Willing and able to comply with the requirements for participation in this study.
排除标准
- •Known history of allergy or intolerance to the investigational products.
- •Any chronic medical condition and/or history of significant medical condition, which in the opinion of the site physician/ investigator may risk participant wellbeing/ safety, impede participant compliance with study procedures or ability to complete the study and/ or could confound the primary objectives of the study.
- •Any acute illness or any recent medical intervention including vaccination within 14 days before the first dose of investigational product.
- •Female participants who are pregnant or intending to become pregnant, lactating and/or breastfeeding. Women of childbearing potential who are not currently using medically effective forms of contraception.
- •Use of prescription drugs known to potentially interact with NAD precursors within 14 days or 5 half-lives (whichever is longer) prior to the first dose of investigational product.
- •Use of multivitamin/ multimineral supplements, NAD+ precursor supplementation (e.g., niacin, nicotinic acid or niacinamide), L-tryptophan supplementation and/ or any over-the- counter (OTC) medication promoting "healthy aging" or "anti-aging" or "longevity" up to 30 days before first dose of investigational product.
- •On a self-restricted diet, controlled diet or special therapeutic diet up to 30 days before first dose of investigational product.
- •Average alcohol consumption greater than 2 standard drinks per day over a week for males, and greater than 1 standard drink per day over a week for females. One standard drink contains 10-12 g of ethanol. Examples of standard drinks are one beer can (300 ml), one glass of wine (100 ml) or one glass of schnaps (30 ml).
