Overview
Dr. Berg's magnesium glycinate capsule bundles chelated magnesium with vitamin D3, B6 and zinc in a single capsule, sold in a 150 count bottle aimed at muscle, nerve, sleep and stress support. The listing describes it as lab-tested and made without fillers in a GMP-certified US facility.
Where a plain magnesium glycinate product is magnesium alone, this formula bundles in D3, B6 and zinc, which is the 4-in-1 the name refers to. The specific magnesium dose per capsule is not broken out separately from the other three ingredients in the spec data.
- 4-in-1 formula: magnesium, D3, B6 and zinc
- 150 vegetarian capsules per bottle
- Lab-tested, no fillers
- Made in a GMP-certified US facility
Who it's for
For people wanting magnesium paired with D3, B6 and zinc in a single capsule rather than taking each separately. Not for anyone who wants a magnesium-only product with no added vitamins.
Strengths and trade-offs
Drawn from this product's published specifications.
- Combines magnesium glycinate with D3, B6 and zinc

- Made in a GMP-certified US facility, no fillers stated

Performance notes
Pairing magnesium glycinate with B6 and zinc follows a common combination used for nerve and stress support, and D3 is added on top for broader coverage. The listing states the product is lab-tested and made without fillers, though individual milligram amounts for D3, B6 and zinc are not itemized in the provided spec data.
