NAD+ supplements or NAD Boosters (often precursors) are products designed to increase the levels of NAD+ (nicotinamide adenine dinucleotide), an essential molecule that plays a key role in various cellular processes, including energy production, DNA repair, and aging

NAD+ boosters work by increasing the levels of NAD+ in the body. They usually contain precursors, compounds that can be converted into NAD+ within the body, or other substances that stimulate the production or activity of NAD+.

While NAD+ boosters are generally considered safe, some users may experience mild side effects such as stomach discomfort, diarrhea, or headaches. It's important to follow the recommended dosage and consult a healthcare professional before starting any new supplement regimen.

The duration and degree of effects from NAD+ boosters can vary from person to person. Some individuals may notice improvements in energy levels and cognitive function within a few weeks, while others may require several months of consistent use. It's important to maintain realistic expectations and understand that the benefits of NAD+ boosters may be subtle and gradual.
