Before You Contact Us

You’ll often get a faster answer by checking our self-service resources first. The FAQ covers common questions about dosage, ingredients, safety, and orders. The Troubleshooting guide walks you through step-by-step fixes for the most reported effectiveness issues. If your question isn’t answered there, we’re just an email away.

​
What to Include in Your Message

To help us resolve your issue as quickly as possible, include the following details when you contact us:
  • Your order number — required for any questions related to shipping, tracking, or returns (found in your confirmation email)
  • The lot number on the bottom of your bottle — needed for ingredient queries, quality concerns, or adverse reaction reports
  • A brief description of your concern — the more specific you are, the faster we can help (for example: “I’ve been taking 1 mL for 10 days and I’m still waking up at 3 AM”)

​
Returns & Refunds

Yu Sleep stands behind its product with a 30-day satisfaction guarantee on all first-time orders. If you’re not satisfied with your experience, here’s how the process works:
  1. Email hello@yusleep.com with your order number and a brief note about why you’d like to return the product — within 30 days of your delivery date.
  2. Our team will confirm your return and provide instructions. You do not need to return the physical bottle to be eligible for a refund on a first-time order.
  3. Refunds are processed to your original payment method within 5–7 business days of your approved return request.
The satisfaction guarantee applies to first-time orders only. Repeat orders are subject to our standard return policy, which requires the product to be unopened and returned within 14 days of delivery. Contact support for details.
