NAD+ IV vs. NAD+ Injections: Which One Is Right for You?

NAD+ has become one of the most talked-about names in longevity, and at bioworX Leon Springs in San Antonio it comes in two formats: a full IV infusion and a quick intramuscular injection. They deliver the same coenzyme, but they are not interchangeable. Choosing between them comes down to your goals, your schedule, and where you are in your NAD+ journey.

This guide breaks down what NAD+ does, how the two delivery methods differ, what each session involves, and which protocol tends to fit which goal — so you can walk into your NAD+ consultation already knowing the right questions to ask.

What NAD+ Actually Does

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every cell of your body. It is essential for cellular energy production (ATP), DNA repair, gene expression, and the activity of longevity-related proteins called sirtuins. Without enough NAD+, cells cannot produce energy efficiently — which is why low NAD+ is associated with fatigue, brain fog, and slower recovery.

NAD+ levels also decline naturally with age. By your 40s, levels may be roughly half of what they were in your 20s, and stress, poor sleep, alcohol, and inflammation accelerate the drop. Replenishing NAD+ is one of the more promising strategies in longevity science, and direct delivery — IV or injection — reaches therapeutic levels that oral supplements struggle to match.

Why Delivery Method Matters: Bioavailability

Oral NAD+ precursors like NMN and NR are popular, but they face a bioavailability problem: much of the dose is broken down in digestion before it reaches your cells. IV and intramuscular delivery bypass that bottleneck, getting NAD+ into the bloodstream directly. The difference between the two clinical options is mostly about dose and absorption speed, not whether the NAD+ gets in.

An IV infusion delivers a high dose slowly over a longer session, allowing your body to absorb a large amount with the drip rate controlled for comfort. An injection delivers a smaller, concentrated dose into muscle in minutes. Both are administered by trained medical staff at bioworX in San Antonio.

NAD+ IV Infusion vs. NAD+ Injection

Here is how the two stack up side by side:

	NAD+ IV Infusion	NAD+ Injection
Dose	Higher therapeutic dose	Lower, targeted dose
Session time	About 1.5–3 hours	About 10 minutes
Delivery	Intravenous drip	Intramuscular injection
Best for	Initial loading, deep cellular restoration, comprehensive longevity goals	Maintenance between IV sessions, busy schedules, trying NAD+ for the first time
Typical cadence	Loading phase of 3–5 sessions over 1–2 weeks, then maintenance every 2–4 weeks	Weekly or biweekly, adjusted to your goals

Many clients use both: IV infusions for deep cellular restoration during a loading phase, then injections to maintain their levels between full sessions. There is no single right answer — the best protocol is the one that fits your goals and your calendar.

What a NAD+ IV Session Is Like

Your first NAD+ IV begins with a complimentary discovery call, where the medical team reviews your health goals, history, and any symptoms to set the right dose. During the infusion — typically 1.5 to 3 hours depending on dosage — you can relax, read, or work. Some clients feel mild warmth, flushing, or a sensation of chest tightness; these are normal and easily managed by slowing the drip rate, which is exactly why staff monitoring matters.

Many people notice improved clarity and energy within hours, but the fuller benefits of NAD+ build across multiple sessions. That is why an initial loading phase followed by maintenance tends to outperform a single infusion.

What a NAD+ Injection Is Like

A NAD+ injection is the express lane. The intramuscular dose takes about 10 minutes including preparation, with no IV line and no extended sit time. It is ideal for clients maintaining their NAD+ levels between infusions, anyone with a packed schedule, or someone who wants to try NAD+ in a shorter, more accessible format before committing to a full IV.

First-time injection clients receive a brief consultation; returning clients can often schedule a quick session and be on their way. Many people add a NAD+ injection onto a cryotherapy or IV drip visit to stack benefits in one trip.

Which One Is Right for You?

Choose the IV infusion if you are just starting NAD+ and want a strong loading phase, if longevity and deep cellular restoration are your priority, or if you have specific goals you have discussed with the medical team. Choose the injection if you are maintaining levels between infusions, if time is tight, or if you want a low-commitment way to experience NAD+ first. For many clients in San Antonio, the answer is a combination — and your consultation is where that plan gets built.

NAD+ also anchors the LifeWorx Longevity Program, which combines NAD+ with ozone and exosome therapy for a comprehensive regenerative approach. If longevity is your bigger goal, it is worth asking about.

Frequently Asked Questions

How fast do you feel results from NAD+?

Many clients notice improved mental clarity and energy within a few hours of an infusion, though the fuller benefits of NAD+ build over multiple sessions. Injections offer a quicker, lighter boost. Results vary by person, dose, and how depleted your baseline NAD+ levels are.

How long does a NAD+ IV session take?

NAD+ IV infusions typically run 1.5 to 3 hours depending on the dosage, while NAD+ injections take about 10 minutes including preparation.

How many NAD+ sessions do I need?

Many clients start with a loading phase of 3 to 5 IV sessions over 1 to 2 weeks, followed by maintenance every 2 to 4 weeks or regular injections in between. Your consultation determines the right protocol for your goals.

Does NAD+ therapy have side effects?

Some clients experience mild warmth, flushing, or chest tightness during an infusion. These are normal and managed by slowing the drip rate, with medical staff monitoring you throughout the session.

Can I take NAD+ orally instead?

Oral NAD+ precursors like NMN and NR have limited bioavailability because much of the dose is broken down in digestion. IV and intramuscular delivery reach therapeutic blood levels that oral supplements generally cannot.
