Are Zelenko Labs products HSA/FSA Eligible? Yes!

As of May 2025, Zelenko Labs has partnered with Wellness Pay to make using your Health Savings Account (HSA) or Flexible Spending Account (FSA) easy and compliant.

Eligible Zelenko products—including Z-Stack supplements (both one-time and subscription) and prescription-based emergency kits—can now be purchased using HSA/FSA funds through ZStackLife.com.

How it works:

1. Add eligible products to your cart

2. Select “Pay with Wellness Pay” at checkout

3. Complete a short health questionnaire for review by a licensed healthcare provider

If your Letter of Medical Necessity (LMN) is approved, you’ll receive it by email and can submit it along with your receipt for reimbursement from your HSA/FSA provider.

Not approved? You may request a refund directly through Zelenko Customer Support.
Approval notifications are typically delivered within one business day.
