Interest in NAD+ keeps growing, so the market now offers NAD supplements as tablets, capsules and powders, while clinics offer NAD+ infusions. The difference is not just the price: they differ in what you actually take in, how much of it reaches your cells and how quickly you feel the effect. In this article we explain how NAD supplements work, how the infusion differs and how to choose what makes sense for your goal.
What is NAD+ in short?
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme that lets cells turn food into energy and repair damage. NAD+ levels naturally decline with age, which is linked to fatigue, weaker focus and slower recovery. We covered the coenzyme itself in more detail in NAD+ infusion: effects and experiences.
NAD supplements: what are you actually buying?
Most products sold as NAD tablets or NAD capsules do not contain NAD+ itself but its precursors, most often nicotinamide riboside (NR) or nicotinamide mononucleotide (NMN). After digestion, the body still has to convert them into NAD+, and how much it actually uses depends on the product, the dose and your individual metabolism. Supplement quality varies widely, which is one more reason to discuss your choice with a doctor.
NAD+ infusion: direct replenishment
With an infusion, NAD+ enters the bloodstream directly, at the full dose, with no losses through digestion. The therapy is carried out at the clinic, after a doctor's assessment and under the supervision of medical staff throughout the procedure. That is why the infusion is chosen when fast and reliable replenishment is the goal, for example as part of anti-aging protocols or energy and recovery programs. Read everything about the therapy on the NAD+ therapy page.
What should you choose?
Supplements and infusions do not exclude each other. In practice, the infusion is used for the initial replenishment and for protocols supervised by a doctor, while supplements can support maintenance between visits, if the doctor recommends them. The right order depends on your health, habits and goal, so the most useful step is to decide at a consultation rather than based on a product advertisement.

Frequently asked questions
Do NAD tablets work the same as an infusion?
Not the same. Tablets and capsules contain precursors that the body still has to convert into NAD+, with losses during digestion. The infusion delivers NAD+ directly into the bloodstream at the full dose, so the replenishment is faster and more predictable.
Which is better: NAD supplements or a NAD+ infusion?
It depends on the goal. The infusion is used for fast replenishment and doctor-supervised protocols, while supplements can support maintenance. The best choice is the one you make with a doctor at a consultation.
How much does a NAD+ infusion cost?
The price depends on the dose and the number of infusions in the therapy plan. See the current prices in the Miren Medic price list; you receive an exact plan after a consultation with the doctor.
How do I start NAD+ therapy?
The first step is a consultation: the doctor assesses whether the therapy is right for you, how many infusions make sense and at what interval. You can book a consultation by phone or through the website.
