GLP-1 Nutrition
The NAD+ Mistake Many People Make on GLP-1
TLDR: All you need to know
If you’re on a GLP-1 medication and added NAD+ for energy, recovery, or mental clarity, you’re not alone. The most common mistake is assuming all NAD+ works the same regardless of how it’s delivered. On GLP-1, digestion changes can make oral supplements feel slower or inconsistent — not because NAD+ “stopped working,” but because absorption is different. For many people, clinician-guided NAD+ injections feel more predictable because they bypass digestion entirely.
If you’re on a GLP-1 medication and added NAD+ for energy, recovery, or mental clarity — you’re not alone. But many people make the same mistake without realizing it: they assume all NAD+ works the same, regardless of how it’s delivered. On GLP-1, that assumption matters more than you think.
Why NAD+ Feels Different on GLP-1
GLP-1 medications slow gastric emptying and change how nutrients move through your digestive system. That’s part of why they help regulate appetite — but it also affects absorption. So when people take oral NAD+ supplements, they may notice slower or inconsistent effects, minimal energy improvement, or an “it worked before, but not now” feeling. Not because NAD+ stopped working — but because delivery matters more on GLP-1.
The Core Issue: Absorption, Not Dosage
Most NAD+ supplements rely on digestion to be absorbed. On GLP-1, digestion is slower and less predictable. That means absorption can be delayed, bioavailability may be reduced, and effects can feel muted or inconsistent. This leads many people to increase dose, switch brands, or stack supplements — without solving the real problem.
NAD+ Supplements vs NAD+ Injections (On GLP-1)
| Feature | NAD+ Supplements | NAD+ Injections |
|---|---|---|
| Delivery path | Digestive system | Direct to bloodstream |
| Reliant on digestion | Yes | No |
| Absorption speed | Slow / variable | Fast / predictable |
| Consistency on GLP-1 | Often inconsistent | Much more consistent |
| Time to feel effects | Weeks for buildup | Often hours to days |
| Best for GLP-1 users | Limited | Preferred |
Why Injections Often Feel “More Effective”
This isn’t about stronger dosing — it’s about bioavailability. NAD+ injections avoid digestive slowdown, deliver NAD+ directly where cells can use it, and reduce variability day-to-day. For people on GLP-1, that difference can be the line between “I think it’s helping” and “I can actually feel it.”
A Common Mistake: Trying to “Fix” Supplements
After missing results, many people respond by increasing supplement dose, taking NAD+ with food or fasting, or adding more stimulants or adaptogens. These approaches often increase frustration — not results. On GLP-1, changing the delivery method is usually more effective than changing the dose.
So… Is NAD+ Still Worth It on GLP-1?
Yes — when it’s delivered in a way that works with your physiology, not against it. NAD+ can support cellular energy, recovery and fatigue management, mental clarity during appetite changes, and overall metabolic resilience. But on GLP-1, how you take it matters as much as why you take it.
The Bottom Line
If you’re on GLP-1 and feel like NAD+ “isn’t doing much,” the issue may not be NAD+ itself — it’s absorption. That’s why many GLP-1 patients transition from supplements to clinician-guided NAD+ injections for consistency, predictability, and clearer results.

FAQ
Why does oral NAD+ feel weaker on GLP-1?
GLP-1 slows gastric emptying, which can delay or reduce absorption of oral supplements. The issue is often bioavailability, not dosage.
Are NAD+ injections “stronger” than supplements?
Not necessarily stronger — just more direct. Injections bypass digestion, which can make effects feel more predictable for some people on GLP-1.
Should I increase my NAD+ supplement dose if I don’t feel much?
Increasing dose may not solve the core issue if absorption is inconsistent. Discuss options with a clinician, including delivery methods.
