Current Uncertainties and Future Challenges Regarding NAD+ Boosting Strategies.

Area of Science:

• Biochemistry
• Gerontology
• Nutritional Science

Background:

• Nicotinamide adenine dinucleotide (NAD+) boosters, including precursors and enzyme modulators, are increasingly popular for anti-aging and health.
• Public interest in health-promoting lifestyles fuels demand for NAD+ boosters as dietary supplements.

Purpose of the Study:

• To review current trends in NAD+ precursor usage.
• To identify uncertainties regarding dosage, timing, safety, pharmacokinetics, and pharmacodynamics of NAD+ boosters.
• To highlight the need for further clinical trials and research.

Main Methods:

• Literature review of current NAD+ booster research and trends.
• Analysis of existing data on NAD+ precursor usage, safety, and efficacy.
• Identification of knowledge gaps in pharmacokinetics, pharmacodynamics, and long-term effects.

Main Results:

• NAD+ boosters are widely used, but significant uncertainties exist regarding their optimal application.
• Key unknowns include bioavailability, metabolism, tissue specificity, and long-term safety.
• Lack of long-term safety studies necessitates more clinical trials.

Conclusions:

• Further clinical trials are essential to determine appropriate NAD+ booster dosages and treatment durations for aging and disease.
• Research must address long-term consequences of elevated NAD+ levels and optimal strategies for increasing NAD+.
• Enhanced understanding will enable safer and more effective use of NAD+ boosters.
