What Is NAD — and Is It a Peptide?
NAD comes up constantly in longevity and wellness conversations — often in the same breath as peptides, which causes real confusion. This article explains what NAD actually is, answers the common question of whether NAD is a peptide (it isn't), and describes how NAD support is typically discussed inside a broader wellness plan. It is educational only and not medical advice.
What to expect

What NAD actually is
NAD — nicotinamide adenine dinucleotide — is a coenzyme found in every living cell. It plays a central role in how cells convert food into energy and is involved in processes like DNA repair and cellular signaling. Your body makes NAD continuously, largely from vitamin B3 (niacin) and related precursors in the diet. It is not exotic; it is foundational biochemistry that has recently become a wellness topic.
Is NAD a peptide? No — here's the difference
NAD is frequently mentioned alongside peptide therapy, but it is not a peptide. Peptides are short chains of amino acids — small protein fragments that act as signaling molecules. NAD is a coenzyme built from a vitamin-derived backbone, with a completely different structure and role. They get grouped together in marketing because both show up in "anti-aging" and "performance" conversations, but chemically and functionally they are separate categories. If a source treats them as interchangeable, that is a sign the information is marketing-driven rather than accurate.
Why interest in NAD has grown
NAD levels tend to decline with age, and laboratory research has explored links between NAD and cellular energy, metabolism, and repair pathways. That research is genuinely interesting — and also frequently overstated in advertising. Much of the most eye-catching work is preclinical or early-stage, and human evidence for many specific claims is still developing. An honest conversation separates "this is a real coenzyme with real biological roles" from "this product will reverse aging," which is a marketing claim, not a clinical one.
How NAD support is typically given
NAD support is most often discussed as an IV infusion, and sometimes as oral precursors the body can convert toward NAD. IV sessions tend to run longer and slower than a basic vitamin drip, and some people report discomfort during infusion that is managed by adjusting the pace. As with any IV therapy, candidacy, screening, and proper administration matter — it is not a one-size-fits-all menu item.
Where NAD fits — and where expectations belong
At Simply Health Integrated Medical, IV nutrient therapy is offered as a wellness option for selected patients after screening, and NAD is best understood inside that honest framing: a supportive option that may fit some wellness goals, not a cure or an anti-aging guarantee. If your underlying question is about energy, recovery, or healthy aging, the more useful starting point is an evaluation that looks at the whole picture — sleep, thyroid, hormones, nutrition — rather than reaching for a single trendy infusion.
The honest next step
If NAD or IV therapy is on your radar, the right move is a conversation that sets realistic expectations and checks whether it fits you specifically. Call (636) 590-4686 or request a consultation, and the team can review your goals and explain where NAD support may — or may not — make sense in St. Louis.

Frequently asked
Common questions
▸Is NAD a peptide?
No. NAD (nicotinamide adenine dinucleotide) is a coenzyme built from a vitamin-derived backbone, while peptides are short chains of amino acids. They have different structures and roles and only get grouped together in marketing. Treating them as the same thing is a sign of marketing-driven, rather than accurate, information.
▸What does NAD do in the body?
NAD is a coenzyme present in every cell that helps convert food into usable energy and is involved in processes like DNA repair and cellular signaling. It is something the body makes and uses naturally, not a drug.
▸Does NAD therapy reverse aging?
Claims that NAD reverses aging are marketing, not established clinical fact. NAD levels tend to decline with age and the research is interesting, but much of it is early-stage and human evidence for specific anti-aging claims is still developing. It is best framed as a supportive wellness option, not a cure.
▸How is NAD given, and is it offered in St. Louis?
NAD support is most often discussed as an IV infusion, and sometimes oral precursors. Simply Health Integrated Medical offers IV nutrient therapy as a wellness option after screening. Call (636) 590-4686 or request a consultation to review candidacy.
