Refund Policies Explained: 30, 60, 90 and 365 Days

The refund window is one of the strongest trust signals a vendor can publish — but it is also one of the most misunderstood. Here is what each tier really means.

The tiers

• 30 days — the baseline. Enough to notice side effects, rarely enough to judge results.
• 60 days — the common industry standard for supplements.
• 90 days — above average; signals vendor confidence.
• 180–365 days — the strongest published guarantees in the category. In our data, they correlate with the highest SiftScore trust components.

What a refund window does NOT protect you from

• Auto-ship clauses. Some vendors hide a second charge in the fine print. That is a documented red flag in our legitimacy checks — regardless of refund length.
• Shipping costs. Some policies refund the order "minus shipping". We note this on product pages when documented.
• The product not working. Refund windows are about getting your money back, not about efficacy. Efficacy has no guarantee in this category — anyone promising one is making an exaggerated claim.

How we use refund data

The refund window feeds two SiftScore components (Value and Trust), and a zero-value window — meaning no verified policy — automatically downgrades a product's legitimacy verdict to at least caution.

Before buying, read the official refund policy yourself and check for the red flags listed on each legitimacy page.
