There is no useful single winner across a delivered vial, a nasal product and a local infusion appointment. This shortlist starts with what you are trying to compare and identifies the detail most likely to change the purchase.
We may earn a commission from partner links. Our reviews cover both partners and other providers. How we are funded
Grouped by ingredient, care format and purchase terms, with the reason to consider each option.
These are editorial starting points from the provider atlas, chosen for a specific comparison: ingredient and route, formula clarity, a meaningful purchase choice, or a care setting. Each entry includes a reason to consider it and a limitation. We do not assign a clinical score or rank different molecules as equivalent treatments. Affiliate relationships do not determine the groupings, and the list includes providers without an affiliate relationship.
Thomas Reed reviewed published product and purchase information. This is not a personal treatment trial or laboratory test. Prices and availability can change; the linked review explains the offer and unresolved details. Read our editorial standards.
A broader menu can support the conversation with a clinician. It does not show that every listed route has the same evidence or effects.
AgelessRx lists injection, nasal and patch options. Its monthly and per-kit prices use different units, and the customer survey is not a randomized head-to-head trial of those routes.
A useful first comparison for readers who want to discuss several formats rather than arrive with one already chosen.
CoreAge lists injection and nasal options. Payment is collected before medical review, and a consultation fee may remain non-refundable. Current-order cancellation and stopping future renewals are separate actions.
Worth investigating if you want these formats and are comfortable reviewing the exact purchase terms before paying.
Look for a complete prescribed supply, the amount due today and who supports the patient after delivery. A vial amount alone does not establish duration.
Sprout describes a 1,000 mg vial and an included home-injection kit. That is useful detail, but a reliable total price and refill arrangement still need to be established.
A focused injection comparison when delivered quantity is more useful to you than a headline monthly figure.
Live Vital describes a three-month NAD+ protocol. Review the total payment alongside the monthly equivalent and confirm what the chosen supply includes.
A comparison for readers prepared to evaluate a multi-month purchase rather than a month-to-month headline.
HealthRX lists injectable and nasal NAD+ products. Its format-specific descriptions should be checked separately; language about an IV does not automatically describe a home injection.
A useful second quote when the precise formulation and route are already the focus of your discussion.
Appointment availability and the actual studio contract matter. Location-based services do not become identical simply because they share a brand name.
Restore offers NAD+ and Niagen NR services. Selected plans recur every 28 days, and NAD loading plans have a six-month minimum. Services and pricing vary by studio.
A local-service comparison when appointment access and the full minimum commitment are clear.
My strongest preference is for a complete, understandable offer. That means the exact formulation, who provides care, the dispensing or appointment arrangement, and the financial commitment. It is not a judgment that a particular route will improve energy, cognition or longevity.
