Refund Policy Overview
This Refund Policy applies to all purchases made through the official Complete Thyroid website at www-completethyroid.com and is operated by Happier Healthier Supplements, the company behind Science Natural Supplements.
By placing an order, you agree to the terms outlined in this policy. We recommend reviewing this page before purchasing so you fully understand your rights and options.
Key fact: The 180-day guarantee window begins on the date your order was placed — not the delivery date. Keep your order confirmation email as proof of purchase and reference for any refund request.

How to Return Your Product
If our support team requests you return the product, please follow these instructions:
What to Return
- Any unused or partially used bottles associated with your order
- Original product packaging where possible (not required but helpful)
- A note inside the package with your full name and order number
Where to Send Returns
Return Address:
Happier Healthier Supplements — Returns Dept
600 17th Street, Suite 2800 South Tower
Denver, CO 80202, United States
Shipping Your Return
- We recommend using a tracked shipping service to confirm delivery
- Return shipping costs are the customer's responsibility unless the return is due to a defective or incorrect item
- For damaged or incorrect orders, we will provide a prepaid return label
- Do not ship returns to any other address — returns sent to the wrong address cannot be processed
Tip: Keep your shipping tracking number until your refund has been confirmed. If a return package is lost in transit, the tracking number helps us resolve the issue on your behalf.
Damaged, Defective or Incorrect Orders
If your order arrives damaged, defective, or contains the wrong product, we will resolve the issue at no cost to you.
- Email us at [email protected] within 14 days of delivery
- Include your order number and photos of the damaged or incorrect item
- We will either ship a replacement at no charge or issue a full refund — your choice
- You do not need to return damaged items in most cases
No hassle for damaged orders. If the product arrived in poor condition through no fault of your own, we cover it fully — no return shipping cost, no waiting period.
Order Cancellations
Orders can be cancelled if they have not yet been shipped. Once an order has been processed and handed to a carrier, it cannot be cancelled — however, you may still return it under the 180-day guarantee once it arrives.
To Cancel an Order
- Contact us immediately at 1-888-861-2035 or [email protected]
- Provide your order number and request cancellation
- If the order has not shipped, we will cancel it and issue a full refund within 3–5 business days
- Orders are typically processed and shipped within 1–2 business days of being placed
Act quickly. Because orders ship fast, the window to cancel is narrow — typically within a few hours of placing your order. If you miss the cancellation window, the 180-day return policy still applies once you receive the item.
