Willow NAD+ Review 2026: $199/mo Injections, HSA/FSA Eligible
- Physician-prescribed only
- 30 providers compared
Willow is the NAD+ option for people who want to pay with an HSA or FSA card and want one flat monthly price. It costs $199 a month, which is above the entry price of many rivals, but it comes with doctor messaging and around-the-clock support. It sells injections only, taken three times a week to start.
What Is Willow?
Willow is a telehealth platform best known for weight-management programs, and NAD+ sits alongside them. That matters for two reasons. The platform is built for ongoing clinician contact, and NAD+ is not its only product, so it is not the specialist some rivals are.
Willow pitches NAD+ on steady, natural-feeling energy rather than a stimulant hit, with clearer thinking and a more vibrant-looking complexion. Those are marketing claims, and results vary by person. Our guide to what NAD+ is explains what is and is not established.
The Willow NAD+ Injection
It is a subcutaneous injection, taken three times per week to start. After the first month you can stay at that frequency or move to once-weekly dosing. The vial, syringes and needles are included.
Willow lists mild side effects as redness or soreness at the injection site, brief flushing, fatigue or a mild headache. It also states that compounded NAD+ is not FDA approved and is prepared by state-licensed compounding pharmacies.
Willow NAD+ Pricing
The price is a flat $199 a month, and the product is HSA/FSA eligible, so you can use pre-tax funds. There is no dose-based price ladder to track. Shipping is free.
Willow does not publish its cancellation terms on the page we reviewed, so confirm them before you pay. For cheaper starting points, see our NAD+ treatment cost guide.

Verdict
Willow is a sensible choice if you want pre-tax payment, a single flat price and plenty of support, and you are happy to self-inject three times a week. If price or a nasal option matters more, other providers fit better.
