30-Day First-Bottle Trial
These updated terms apply to new checkouts started on or after September 10, 2026 at 3:00 p.m. Pacific (September 10, 2026 at 22:00 UTC). Orders and checkouts started before that time keep their earlier terms, described below.
If your first USA Magnesium order contains exactly one bottle, you may try it and request a trial refund within 30 days of delivery if it is not right for you. One trial refund per customer. Opening or finishing that bottle does not prevent an eligible trial refund.
30-day trial refund on your first order only, when you choose one bottle. Bundles and repeat orders excluded. Original shipping is nonrefundable. No physical return required.
Bundles, orders containing more than one bottle and repeat orders are not eligible for a voluntary satisfaction refund, even if bottles remain sealed. A first bundle order does not create eligibility for a later single-bottle trial.
These limits do not apply to damaged, defective, incorrect or missing orders, or limit your rights under applicable law.
No Physical Returns
We do not accept physical returns, including sealed bottles. Please do not mail any product back. Eligible trial refunds do not require a return.
Contact support with your order number and contact email. We will review your order and delivery records, confirm eligibility, and explain the refund amount before processing.
- Submit trial refund requests within 30 days of delivery
- Include order number and contact email

Product Quality Commitment
If your order is missing or a product arrives damaged, defective or incorrect, contact us promptly so we can investigate and arrange an appropriate replacement or refund. The first-order, single-bottle and trial-window limits do not apply to these issues. No physical return is required. This voluntary satisfaction policy does not limit your rights under applicable law.
Earlier Orders and Checkouts
Orders placed or checkouts started before September 10, 2026 at 3:00 p.m. Pacific (September 10, 2026 at 22:00 UTC) keep the terms offered when the checkout began. The new 30-day, single-bottle and first-order restrictions do not apply retroactively. We also honor any more favorable return promise shown when you purchased.
For checkouts started before September 9, 2026 at 11:30 p.m. Pacific (September 10, 2026 at 06:30 UTC), the original policy allowed a refund request within 90 days of delivery. Approved refunds include amounts paid for product and original shipping, with no restocking fee. We will cover required return postage under those earlier terms. In some cases, a physical return was not required. We now waive physical returns without reducing those refund rights.
For checkouts started from September 9, 2026 at 11:30 p.m. Pacific (September 10, 2026 at 06:30 UTC) until September 10, 2026 at 3:00 p.m. Pacific (September 10, 2026 at 22:00 UTC), the 90-day one-opened-bottle policy applies. Approved refunds include product and original shipping, with no restocking fee. You may open one bottle per order. Keep additional bottles factory sealed. Opening a second bottle makes the order ineligible for the satisfaction guarantee. You pay return postage if a return is required. We now waive physical returns and any return-postage requirement for those orders.
Send your order number to support so we can review the purchase and original checkout records. If we cannot confirm which terms were shown, we will use the earlier, more favorable terms. These website terms do not replace a marketplace's own return policy.
