Sleep Supplement Guides

Two long reads, neither of which is trying to sell anything. One walks the category ingredient by ingredient and attaches the dose to each. The other is a seven-question test you can run on any bottle, in a shop or in a browser tab, in under a minute.

Both are written for a reader who closes the tab without buying anything.

The index

The two guides

One on the evidence, one on reading a label.

What the evidence supports across sleep supplements

Melatonin has a settled effective dose and it is smaller than most labels carry. Magnesium has one decent trial and a pooled analysis. Valerian is the most-studied herb in the category and it is not in every product that borrows its evidence. Ashwagandha has the best recent result and a liver signal worth knowing about. This guide sets all of that out with the doses attached.

Read the evidence guide

Seven checks to run on any sleep supplement label

Seven questions, arranged so the first one gates the rest: is there a weight beside every name, is the melatonin figure a physiologic one, is the plant part stated, does the evidence belong to the ingredient or to a pairing, is the interacting ingredient flagged, is there a refund route, and can a batch be traced. The last section runs all seven over this product.

Editorial policy

Why a retail desk publishes guides that cost it sales

What these two pages are for, and why one of them is unflattering.

The second of these two guides scores the product this website sells and the product fails three rows of the scorecard in public. That is deliberate.

A reader who arrives here has already read a sales letter. What they need next is a way of judging any bottle, including this one, and a checklist that this particular product happened to pass on every row would be worthless as a checklist.

The first guide is written the same way. It covers valerian, which is not in the product this desk sells, because valerian is the most-studied herb in the category and a guide that left it out to avoid the comparison would be a brochure.

Two months, which is about as long as the sleep trials behind these ingredients ran

The chamomile, ashwagandha and lemon balm studies ran four to eight weeks, so a window of 60 days is long enough to reach the end of one and decide. It runs from the date of purchase, opened bottles included. Call the order desk with your order ID and follow the steps on the refund policy page.
