Magsera | Product-first magnesium route
Magnesium Acetyl Taurate for calm, sleep, stress-resilience, and focus-without-stimulation formulas.
A differentiated magnesium-acetyl-taurine ingredient route for brands that need something more ownable than generic magnesium glycinate and less crowded than magnesium L-threonate.
Category tension
Magnesium is crowded. Brain-focused magnesium is not.
Most magnesium pages sound the same: relax, sleep, muscle, calm. MgAT gives a brand team a sharper product story: acetyl-taurine chemistry, magnesium identity, NMR authenticity, a full analytical specification, and practical format routes for gummies, powders, soft chews, and drink mixes.
This page starts with the raw material. The platform comes second: calm/sleep, stress-resilience, women’s nightly routine, and focus-without-stimulation product concepts.
Why MgAT is different
Acetyl-taurine identity
MgAT is positioned as a magnesium salt of acetyl-taurine, giving it a more distinctive identity than simple magnesium plus taurine blends.
NMR authenticity route
For buyers concerned about whether a material is true MgAT or a simple blend, 1H NMR review can help distinguish MgAT identity from taurine-magnesium mixtures.
Identity and documentation, not a comparison
Magnesium acetyl-taurate is supplied anhydrous at 98% minimum by HPLC, CAS 75350-40-2, C8H16MgN2O8S2, 356.66 g/mol on the anhydrous formula, with elemental magnesium of 6.39–7.07% by titration stated per lot on the Certificate of Analysis. Comparative absorption literature for this material is summarised in the cited research section below, with the compounds each study actually tested named in full.
Format-first usability
A strong candidate for gummy, powder, soft-chew, and drink-format review where solubility and serving experience matter.
Platform routes
Where MgAT belongs commercially.
For brands building daily calm, stress-resilience, or high-pressure day support concepts without making disease claims.
Nighttime magnesium formulas, soft chews, powder sticks, and women’s daily balance routines.
For nootropic-adjacent brands that want calm-focus positioning without caffeine or stimulant language.
Identity, NMR, assay, application notes, and internal data summaries for R&D, regulatory, and procurement review.
Proof package
What serious buyers should review before launch.
Review acetyl singlet and expected taurine peaks to support authentic MgAT identity.
Specification, Certificate of Analysis, identity and assay method, elemental magnesium, contaminant limits and stability data are available for technical buyer review. Internal preclinical summaries, where they exist, are provided under buyer review and are labelled as internal; they are not published as claims and are not a substitute for peer-reviewed evidence.
Gummy, powder, soft-chew, drink mix, and stick-pack application discussion.
COA/spec, assay, quality documents, claim-safe copy support, and sample route by request.
Buyer-fit examples
Built for brands already selling felt outcomes.
| Buyer pattern | MgAT entry point | Next action |
|---|---|---|
| Women’s calm / sleep gummy brands | More ownable magnesium route than generic glycinate. | Sample + gummy fit review. |
| Liquid / powder routine brands | Water-soluble magnesium route for powder and drink applications. | Application notes + sensory discussion. |
| Traceability-led premium brands | NMR identity, assay, and technical file review route. | Buyer sheet + file package. |
Claim boundary
Strong positioning without overclaiming.
Use: calm-focused formulas, sleep-support formulas, stress-resilience concepts, focus-without-stimulation, magnesium specification route, NMR-authenticated identity review, analytical specification review, and format-review support.
Keep public copy in the structure/function lane: ingredient identity, product-format fit, internal preclinical review, and technical buyer files. Strong marketing first; medical outcome language only after a separate source and regulatory review.
Review MgAT before your next calm or sleep formula looks like everyone else’s.
Request sample availability, buyer sheet, NMR identity notes, technical file package, and application review for gummy, soft-chew, powder, or drink formats.

- Serum and tissue timeline of five magnesium compoundsFollowing a single 400 mg/70 kg dose in rats, compared magnesium sulfate, oxide, acetyl taurate, citrate and malate; reported that serum area under the curve was highest for magnesium malate with magnesium acetyl taurate second, that magnesium acetyl taurate was rapidly absorbed and reached the highest tissue magnesium concentration in the brain of the compounds tested, and that oxide and citrate had the lowest bioavailability versus control. This is a rat tissue-distribution study, not raw-material release testing; identity and assay of supplied material follow the methods stated in our specification and COA.Uysal N, Kizildag S, Yuce Z, Guvendi G, et al. Biol Trace Elem Res. 2019;187(1):128-136. PMID 29679349. DOI 10.1007/s12011-018-1351-9. source
- Dose-dependent tissue distribution of organic magnesium compoundsCompared organic-acid-bound compounds (magnesium citrate and malate) with amino-acid-bound compounds (magnesium acetyl taurate and glycinate) at different doses in rats; reported that brain magnesium levels increased in all magnesium acetyl taurate groups, that magnesium citrate increased muscle and brain magnesium in a dose-independent manner, and that dividing high daily doses did not sufficiently increase tissue magnesium levels. The same matrix note applies: rat study, not raw-material assay.Ates M, Kizildag S, Yuksel O, Hosgorler F, et al. Biol Trace Elem Res. 2019;192(2):244-251. PMID 30761462.
