RNK Health Review: Read the Refund Window
RNK Health is a longevity telehealth platform selling prescription compounded NAD+ in three delivery formats — injectable, nasal and liposomal liquid — each from about $129 a month, with dosing titrated by licensed clinicians and treatment available up to higher doses for patients with documented prior use. It is a direct-pay subscription rather than an insurance product, and the terms around cancellation are the part most worth reading before you subscribe.
Verified August 24, 2026. NAD+ is a longevity treatment, not a weight-loss medication. For weight-loss medication see our GLP-1 provider rankings.

Verdict: A genuine clinician-guided service with three delivery options and transparent-enough subscription mechanics, at a competitive price for compounded NAD+. Two things temper it: refunds close once medication is ordered, and a recurring thread in customer reviews describes receiving lower doses than expected.

Cancel at least two days before billing
You can cancel at any time, but the request must reach RNK at least two days before your billing date to stop the next charge. More importantly, refunds for the current cycle are only available if medication has not yet been ordered — once it has, refunds are generally not given, which the company attributes to pharmaceutical safety and regulatory constraints. That is a standard position for prescription products, but it means the practical refund window is narrow. Diarise your billing date.
At $129 a month, RNK is competitively priced against other compounded NAD+ providers. Verify the dose you are being shipped against what you were quoted, given the recurring customer reports on that point.
What NAD+ Therapy Is, and What the Evidence Shows
NAD+ is a coenzyme central to cellular energy metabolism, and its decline with age is well documented. That much is established biology. The step from there to supplementing NAD+ producing meaningful anti-ageing or energy benefits in humans is where the evidence thins considerably.
Most human research has looked at NAD+ precursors rather than NAD+ itself, and results have been mixed, with effects on biomarkers more consistent than effects on how people actually feel or function. Compounded injectable NAD+ has little direct clinical trial evidence behind it.
Compounded medications are not FDA-approved as finished products and the FDA does not review them for safety, effectiveness or manufacturing quality. That applies here.
What Customers Report
Independent reviews sit in the four-star range across several hundred entries, with many describing responsive customer service and perceived benefit. A recurring negative thread describes receiving a lower-dose shipment than advertised, alongside shipping and temperature-handling concerns.
Both are worth acting on practically: check the vial or product labelling against the dose you were quoted on arrival, and check cold-chain condition where relevant. This page is educational and is not medical advice.

Who Should Pick It — and Who Shouldn't
Good fit
People already committed to NAD+ therapy who want clinician oversight, dose titration and a choice of delivery format at a competitive subscription price.
Look elsewhere
Anyone expecting well-established anti-ageing benefits — the human evidence does not support that confidence. Anyone who wants a straightforward refund if they change their mind. And anyone unwilling to check shipped doses against what was quoted.
Frequently Asked Questions
How much does RNK Health cost?
From about $129 per month for each of its three NAD+ formats — injectable, nasal and liposomal liquid. It is a direct-pay subscription; insurance is not billed.
Can I get a refund from RNK Health?
Only within a narrow window. You can cancel anytime, but the request must arrive at least two days before your billing date, and refunds for the current cycle are only available if medication has not already been ordered. Once ordered, refunds are generally not given.
Does NAD+ therapy actually work?
The biology of NAD+ decline with age is well established. Evidence that supplementing it produces meaningful benefits in humans is thinner — most research has studied precursors rather than NAD+ itself, with mixed results and more consistent effects on biomarkers than on how people feel.
Is compounded NAD+ FDA-approved?
No. Compounded medications are not FDA-approved as finished products, and the FDA does not review them for safety, effectiveness or manufacturing quality.
What do customers complain about?
Independent reviews average in the four-star range, but a recurring thread describes receiving lower doses than advertised, plus shipping and temperature-handling issues. Check the labelled dose against your quote when your order arrives.
Considering RNK Health?
Diarise your billing date given the two-day cancellation notice, and check the dose on arrival against what you were quoted.
