NAD+ boosters are substances or interventions designed to increase levels of [[Nicotinamide Adenine Dinucleotide (NAD)|NAD+ (Nicotinamide Adenine Dinucleotide)]], a critical coenzyme found in every cell, essential for cellular energy production, metabolism, and repair processes. Boosting NAD+ levels is of significant interest in the fields of health and longevity, as declining levels of NAD+ are associated with aging and various age-related diseases. | NAD+ boosters are substances or interventions designed to increase levels of [[Nicotinamide Adenine Dinucleotide (NAD)|NAD+ (Nicotinamide Adenine Dinucleotide)]], a critical coenzyme found in every cell, essential for cellular energy production, metabolism, and repair processes.

NAD+ consumers are enzymes that use NAD+ as a substrate, reducing the available NAD+ in the cell. By inhibiting these consumers, more NAD+ remains available for other cellular processes. | [[NAD+ Precursor|NAD+ precursors]] are compounds that serve as substrates in the biosynthesis of NAD+. They can be converted into NAD+ within the body, thus serving as effective NAD+ boosters. | ||

=== Boosting NAD+ by Inhibiting NAD+ Consumers === | |||
NAD+ consumers ([[NADase]]) are enzymes that use NAD+ as a substrate, reducing the available NAD+ in the cell. By inhibiting these consumers, more NAD+ remains available for other cellular processes. | |||
* '''[[Sirtuins]]:''' A family of proteins that deacetylate proteins and consume NAD+ in the process. Compounds like resveratrol can activate sirtuins and the subsequent cellular effects can create an environment where cells might maintain or produce NAD+ more efficiently, which could indirectly support NAD+ availability. | |||
* '''PARPs (Poly(ADP-ribose) polymerases):''' Enzymes involved in DNA repair that also consume NAD+. Inhibiting PARP activity can help maintain NAD+ levels. | * '''PARPs (Poly(ADP-ribose) polymerases):''' Enzymes involved in DNA repair that also consume NAD+.

* '''[[Caloric Restriction]]:''' Reducing calorie intake without malnutrition can elevate NAD+ levels, potentially through the activation of sirtuins and improved metabolic efficiency. | * '''[[Caloric Restriction]]:''' Reducing calorie intake without malnutrition can elevate NAD+ levels, potentially through the activation of sirtuins and improved metabolic efficiency. | ||
* '''[[Intermittent Fasting]]:''' This dietary approach can also elevate NAD+ levels, likely through mechanisms similar to caloric restriction, such as increased stress resistance and metabolic adaptations. | * '''[[Intermittent Fasting]]:''' This dietary approach can also elevate NAD+ levels, likely through mechanisms similar to caloric restriction, such as increased stress resistance and metabolic adaptations. | ||
=== NAD+ Infusions === | |||
[[NAD+ Infusion|NAD+ infusions]] represent a direct method of increasing NAD+ levels in the body. This intervention involves intravenous administration of NAD+, allowing for higher bioavailability compared to oral supplements. | |||
* '''Effectiveness:''' NAD+ infusions have been reported to quickly elevate NAD+ levels, potentially offering immediate benefits such as enhanced energy, improved mood, and reduced withdrawal symptoms in addiction treatment. | |||
* '''Uses:''' This method is utilized primarily in clinical settings and is explored for its potential benefits in addressing conditions like chronic fatigue, addiction, and age-related cognitive decline. | |||
* '''Safety and Accessibility:''' While generally considered safe when administered under medical supervision, the accessibility, long-term effects, and optimal dosing of NAD+ infusions require further research and standardization. | |||
