Energy at the
cellular level.

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme present in every cell of the body, and it sits at the centre of two jobs that keep those cells running: converting the nutrients you eat into usable cellular energy, and supporting the processes cells use to repair DNA and regulate metabolism. Neither happens without it — which is why the age-related decline in NAD+ draws so much attention. Research suggests NAD+ levels fall substantially over a lifetime, with many estimates placing them at roughly half of young-adult levels by age 50. That decline is one plausible contributor to what people describe as feeling slower with age: lower energy that sleep does not fix, longer recovery after training, and a mental sharpness that takes more effort than it used to. It is worth being measured here — the science of NAD+ and ageing is active and still evolving, and supplementing NAD+ is intended to support the body's own cellular processes, not to reverse anything. What patients at Roots most often report is steadier energy, clearer focus and better recovery, which is consistent with what the coenzyme does rather than a promise of what it will do for any one person.

Both deliver the same molecule — the difference is dose, pace and how they fit your schedule. IV infusions deliver a larger dose over a longer session — NAD+ runs more slowly than a standard nutrient drip, often two to four hours depending on the dose — because a fast drip can cause chest tightness or nausea. That higher dose is why infusions are often used to start a protocol or after a period of high demand. Injections are a quick subcutaneous shot — minutes, no IV line — carrying a smaller dose, which makes them the practical choice for regular maintenance once a protocol is established. In practice, many patients combine the two: an infusion or short series of them to begin, then injections every week or two to hold the level. Which one suits you depends on your goals, your labs and how much time you want to give each session, and it is decided with your provider at consultation rather than in advance.

An IV infusion bypasses digestion entirely and delivers NAD+ straight into the bloodstream, where your cells can put it to work immediately. The drip runs slowly — more slowly than a standard nutrient drip — because NAD+ given too quickly can cause chest tightness, nausea or lightheadedness, so our clinical team paces the infusion and adjusts the rate for comfort as the session progresses. Depending on the dose, a session typically runs two to four hours, and most patients spend that time reading, working or simply resting while the infusion does its work.

Your visit begins with a brief health consultation, where our medical team reviews your history, your goals and any recent labs before the infusion starts. Treatment takes place in our private IV suite and typically takes two to four hours depending on your dose, with the rate adjusted throughout for comfort. Most patients describe feeling clearer and more energized within the first day or two — individual responses vary, and outcomes are never guaranteed.
