NAD+ therapy replenishes your body's most essential coenzyme — addressing fatigue, brain fog, and metabolic slowdown at the cellular level.
Nicotinamide Adenine Dinucleotide (NAD+) is found in every living cell. It drives the reactions inside your mitochondria that convert food into ATP — the fuel your cells run on. Without adequate NAD+, mitochondria become less efficient and the effects ripple through everything: energy, metabolism, cognition, and cellular repair.
Beyond energy, NAD+ activates sirtuins — proteins that regulate DNA repair, inflammation, and cellular stress. These are the same pathways researchers link to healthy aging. NAD+ is also required for PARP enzymes that repair DNA strand breaks, which happens constantly in every cell.
Depleted NAD+ breaks this chain. Less efficient electron transport = less ATP = less energy for every cell — which is why low NAD+ affects everything from physical stamina to cognitive clarity.
NAD+ decline with age is one of the most well-documented phenomena in cellular biology — observed across species and multiple human tissues including skin, liver, and brain. But it doesn't decline evenly. Lifestyle factors dramatically accelerate the drop.
Check any symptoms you're currently experiencing. Your results will show your depletion likelihood and the most appropriate Livea protocol.
NAD+ must reach your cells to work. Subcutaneous injection bypasses the digestive tract entirely, delivering NAD+ directly into the body for rapid cellular uptake.
Cellular energy is the foundation of everything. When NAD+ is depleted, your mitochondria can't produce energy efficiently — and that inefficiency shows up as fatigue, reduced exercise motivation, metabolic slowdown, and cravings that make dietary discipline nearly impossible.
NAD+ has become one of the most studied molecules in longevity and metabolic research. We present the evidence across 5 domains with honest strength ratings — including where research is compelling and where more human data is still needed.
An honest note on the evidence: Most human trials of NAD+ precursors involve small sample sizes (14–100 participants) and short durations (8–12 weeks). Direct subcutaneous NAD+ has fewer formal clinical trials than oral precursors, though the pharmacokinetic case for superior bioavailability is well-established. Livea's position: the mechanistic evidence is strong, patient outcomes are consistently positive in our clinical experience, and the safety profile is excellent. We present these results to patients with appropriate nuance.
NAD+ therapy is appropriate for a wide range of adults experiencing energy decline, metabolic challenges, or cognitive changes. A brief consultation will confirm whether it's right for your specific health status.
A provider consultation will confirm whether NAD+ therapy is safe and appropriate. Livea's medical team takes a conservative, safety-first approach to all treatments.
