EVERY ACTIVITY WE DO STARTS WITH OUR BODIES GENERATING ATP (THE SPECIALIZED CELLULAR FUEL) INSIDE OUR CELLS.
This natural process requires us to be able convert the food we eat into the energy we need. A key component of this process is a specialized molecule called NAD+ (which is short for nicotinamide adenine dinucleotide).
Tru Niagen® Nicotinamide Riboside Is An Advanced Cellular Nutrient Clinically Shown To Boost NAD+ Levels
Tru Niagen® (NR) is a unique form of vitamin B3 that is clinically shown to increase NAD+ levels in as little as 2 weeks.¹ NR’s primary job is to help replenish NAD+ levels to support your cells’ natural ability to transform nutrients into energy in the form of ATP.
WHAT IS NAD+ AND WHERE DOES IT COME FROM?
NAD+ is an important molecule found inside every living cell. NAD+ plays a critical role in cellular energy production, and is also required for normal mitochondrial function, cellular stress response, and DNA repair.²
Our bodies can synthesize NAD+ from dietary precursors found in foods containing various forms of niacin (vitamin B3) or the amino acid tryptophan. These precursors differ in how efficiently they are converted to NAD+.³


WHY IS NAD+ IMPORTANT AS WE AGE?
Research has shown that NAD+ levels decline by up to 50% between the ages of 40 and 60 years. This is related to impaired NAD+ synthesis as well as increased NAD+ demand for processes like DNA repair.⁴⁻⁵
The decline in NAD+ as we age can lead to a decreased capacity to naturally produce cellular energy.⁵ This means cells need to constantly replenish NAD+ to maintain proper function.⁶
Although our cells can make NAD+ from precursor foods found in our diets, the body’s ability to produce enough becomes more of a challenge with age.² Lower NAD+ levels have been observed in individuals with fatigue and in the muscle cells of older adults with sarcopenia (the age-related decline in muscle mass and function).⁷⁻⁸
NICOTINAMIDE RIBOSIDE (NR) AN ADVANCED CELLULAR NUTRIENT CLINICALLY SHOWN TO BOOST NAD+ LEVELS IN OUR CELLS
Tru Niagen® Nicotinamide Riboside (NR) is a unique form of vitamin B3 that is clinically shown to increase NAD+ levels in as soon as 2 weeks.¹ NR’s primary job is to help replenish NAD+ levels to support your cells’ natural ability to transform nutrients into energy in the form of ATP.
