What are the different forms of NAD supplements?
Sources:
There are several forms of NAD (Nicotinamide Adenine Dinucleotide) supplements commonly explored to increase NAD levels in the body, as discussed by experts:
-
NR (Nicotinamide Riboside): This is a precursor to NAD that is typically taken in pill or powder form. It is believed to help increase NAD levels in the body, although its efficacy compared to other forms is under debate 1.
-
NMN (Nicotinamide Mononucleotide): Another precursor to NAD, NMN is often taken as a sublingual powder, meaning it is placed under the tongue for absorption. There is ongoing debate about whether NMN effectively converts to NAD inside cells 1.
-
NAD Infusions: This method involves administering NAD directly into the bloodstream via intravenous infusion. It is assumed to be more effective at boosting cellular NAD levels compared to NR or NMN, though direct comparisons in efficacy are limited 2.
-
Oral NAD: There are also products that claim NAD can be taken orally in liquid or pill form. However, the scientific evidence regarding the impact of oral NAD on cellular levels and overall efficacy is still lacking 2.
These supplements are often used with the aim of enhancing energy and vitality, though there is considerable debate about their role in extending lifespan. notes the importance of focusing on foundational health practices, such as proper nutrition and stress management, alongside any supplementation 2.
