Dr. Berg Magnesium Glycinate Powder for Sleep

Checked against public sources on July 31, 2026 · LookCloser does not sell or recommend supplements.

Does the marketing hold up?

FDA recall appears in this brand's history. An exact-product recall is a direct signal. A different product from the same firm is company context, not a strike against this item.

Trouble on record?Brand history — not this product

“Couldn’t verify” means we looked and found no public proof — not a mark against the product. Most supplement claims cannot be independently verified by anyone, so grey is the normal state of this industry.

The checks, one by one

The public sources did not settle the marketing promises on this label.

Partly confirmed2

“MANUFACTURING”

“GMP-certified” describes factory processes, not what is in the bottle. The claim does not name a certifier or public register that a shopper can check.

“POWDER FOR SLEEP: Support restful nights with magnesium glycinate powder for sleep, relaxation, & stress relief in a delicious raspberry and lemon”

Published research exists for ingredients in this formula. Whether this product’s doses match those studies could not be confirmed.

Ingredient research can support context, but it is not a trial of this exact product.

FDA recall appears in this brand's history

An exact-product recall is a direct signal. A different product from the same firm is company context, not a strike against this item.

Evidence and sources

This recall is not about the product on this page. Health & Wellness Center, Inc. recalled a different product on September 24, 2021. FDA has since closed that case. The recalled item was “Dr. Berg Nutritionals, Liquid Vitamin D with Zinc Dietary Supplement ( Liquid Vitamin D )…”

CheckedIs the label honest?

Every ingredient shows its amount · 6 ingredients listed.

Every ingredient shows its real amount — nothing is hidden in a proprietary blend.

Evidence and sources

The panel gives a per-ingredient amount rather than hiding quantities inside a proprietary blend, so each one can be compared to published research.

CheckedWho is behind it?

The barcode identity checks out · 810110790988.

The barcode matches, so we are checking the right product rather than a look-alike.

Evidence and sources

Open Food Facts resolves 810110790988 to "Magnesium Powder" (Dr Berg) — consistent with this listing.

Locked evidence record →Open the full source-linked finding
CheckedWho is behind it?

Registered in NIH's supplement label database (DSLD)

A government label filing makes the listed formula easier to inspect and compare over time.

Evidence and sources

Label #238774 “Dr. Berg's Electrolyte Powder Raspberry & Lemon Natural Flavor” (Dr. Berg Nutritionals), entered 2020-12-26, with the full Supplement Facts on file. NIH marks this label as off-market (superseded or discontinued version). Company on file: Manufacturer — Dr. …

CheckedCan you trust the review pattern?

Reviews rose from 84 to 270 between July 4, 2025 and July 31, 2026 — no sudden jump.

A count that moves steadily is ordinary. A sudden burst is what deserves a closer look.

Evidence and sources

Written reviews rose from 84 to 270 between July 4, 2025 and July 31, 2026. The largest rise inside any single 30-day window was about 19, so the count moved in steps rather than in one burst.

Research behind the findings

Dose and research context

We could not match an amount on this product to a studied range for the same ingredient, so these links are ingredient background rather than a measurement of this product.

Background reading

What the research says about these amounts

Not a score. Studies disagree with each other and change over time, so this sits beside the evidence rather than counting toward it — it is here so you can read the sources yourself.

The panel lists 325 mg of magnesium per serving. Studies we found used 200 mg–420 mg a day, so this sits inside that range.

0studied 200 mg–420 mg

Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.

The panel lists 10 mg of zinc per serving. Studies we found used 8 mg–40 mg a day, so this sits inside that range.
