What to check on the label

  • Whether the label says 'elemental magnesium' or gives the compound weight (for example '2,000 mg magnesium L-threonate').
  • The salt form named. Different salts contain very different shares of elemental mineral.
  • Capsules per serving. Several products use two or three.

Amounts are per label serving as recorded in the catalog and are not a recommendation. Testing status reflects what the brand lists. Nothing here is medical advice.

Evidence gates dose: the evidence grade sets the ceiling, and the dose decides how much of that ceiling the product reaches. Value = inverse of price-per-trial-dose-day. Community = mean sentiment of external reviews. Safety caps applied after weighting.

This score is our editorial judgment, not a scientific standard. We combine published evidence, dose, price, transparency, and consumer signals into one composite: this is our method, not a peer-reviewed clinical rating. A higher score means a product does better on the factors we weight, not that it is medically proven to work.

Our summary

Thorne's Magnesium Bisglycinate is a clean, single-ingredient 200 mg elemental magnesium powder in a well-tolerated chelate form, verified by NSF Certified for Sport but without a public per-batch COA. The best available sleep-specific RCT on magnesium bisglycinate found only a small effect size at a somewhat higher dose combined with glycine, so buyers should expect a modest, not dramatic, sleep benefit from this product alone. It is a reasonable, well-manufactured magnesium option, but the sleep-support framing runs slightly ahead of the underlying evidence's effect size and exact dose match.
In plain language

Why this scored this way

This Thorne HealthTech Magnesium Bisglycinate scores 8.6, making it one of the highest-scoring products on the site. It delivers 200mg of Magnesium, inside the studied range of 200–500mg with grade A evidence (strong human trial data).

What drives the score up

  • Dose-evidence score of 10.0 reflects good alignment with trial doses.
  • Tested by independent lab (transparency 8.0).
  • Magnesium is dosed at the full research level with grade A evidence (strong human trial data).

What drags it down

  • No public lab certificate available for independent verification.

Why you'd choose it

  • You want a reasonably priced mineral product.
  • You want Magnesium from a Thorne HealthTech product.
  • You want a tested by independent lab product.

Why you might skip it

  • You want a product with a publicly available CoA.
  • You want better value (this is $1.30/day with a value score of 8.3).

Innerbody, 'Best Magnesium for Sleep' roundup
Has affiliate relationship Not a paid placement

Innerbody's 2026 magnesium-for-sleep comparison favors a different single-ingredient glycinate product over Thorne's for its top slot.

Finding: Names Micro Ingredients Magnesium Glycinate as its 'best single-ingredient option for sleep' in the 2026 rankings; Thorne's Magnesium Bisglycinate is not the named top pick in this specific roundup.
How we use it: Used for category-context on competitive positioning against other bisglycinate/glycinate products, not as a specific efficacy judgment on Thorne's formulation.

Tier 4Ingredient RCT (different dose)
Effects of Magnesium Bisglycinate and Glycine Supplementation on Self-Reported Sleep Quality: A Randomized, Double-Blind, Placebo-Controlled Trial
Schuster J, et al. · 2025 · Nature and Science of Sleep · n=155 · 250 mg elemental magnesium (893 mg magnesium bisglycinate) + 1,523 mg glycine per day · 4 weeks
ingredient-levelpeer-reviewed
Insomnia Severity Index score dropped 3.9 points on magnesium bisglycinate vs. 2.3 points on placebo (between-group difference p=0.049, Cohen's d=0.2, a small effect). No significant differences on other measured outcomes (perceived stress, PHQ-4, affect scales).
This is the most directly relevant, largest, and most recent RCT specifically on magnesium bisglycinate for sleep. Its elemental magnesium dose (250 mg) is modestly higher than Thorne's 200 mg per single scoop, and the trial combined magnesium with a substantial glycine dose Thorne's product does not contain, so the finding is only partially transferable to this specific product taken alone at one scoop.

Concludes magnesium supplementation may modestly improve subjective sleep quality, particularly in people with low baseline magnesium status or insomnia symptoms, but calls existing RCTs small and heterogeneous.
Supports the general mechanistic rationale that magnesium (bisglycinate form is well absorbed and low-GI-side-effect relative to oxide/citrate) may aid sleep, but underlying evidence base is rated weak-to-moderate, not strong.

Claim check, vendor claims vs. our reading of the evidence

Not medical advice. We list the strongest claims made by the brand and check each against traceable evidence.

Supported
“Highly bioavailable, gentle-on-the-stomach form of magnesium”
Bisglycinate (glycinate) chelated magnesium is well documented in the literature as better tolerated (less osmotic diarrhea) than magnesium oxide or citrate at equivalent elemental doses, and generally shows favorable absorption versus inorganic salts. This is a mainstream, uncontroversial claim about the chelate form itself, distinct from any specific health outcome claim.
Vendor source
Partial support
“Supports relaxation and sleep (implied positioning, not an explicit disease claim)”
The best available RCT on magnesium bisglycinate for sleep (Schuster 2025, n=155) found only a small effect (Cohen's d=0.2) on insomnia severity versus placebo, at a somewhat higher dose (250 mg elemental) than this product's 200 mg per scoop, and combined with glycine which this product lacks. The mechanistic and marketing framing is reasonable but the clinical effect size for magnesium alone, at this exact dose, is modest at best (https://pmc.ncbi.nlm.nih.gov/articles/PMC12412596/).

What we could not verify

We list this openly. If a claim isn't backed by a source we can trace, we'd rather flag it than repeat it.

  • No public per-batch Certificate of Analysis was located for this SKU despite the NSF Certified for Sport badge.
  • No RCT was located using this exact product (Thorne's 200 mg/scoop bisglycinate powder) as the study material; the closest RCT used a higher dose (250 mg) combined with glycine.
  • The magnitude of sleep benefit reported in the best matching RCT is small (Cohen's d=0.2) and may not be noticeable to all users.
  • Long-term (multi-month/year) safety and efficacy data specific to this dose and form was not identified in this review.
  • Reddit r/Supplements community forum
    positive sentiment

    Community discussion exists, with Thorne’s magnesium bisglycinate described as effective and well tolerated without digestive problems. No single Reddit thread is treated as a representative product review.

Important to know
MagnesiumMagnesium oxide has ~4% absorption and mostly acts as a laxative. Always check the salt form, not just 'magnesium'.

Editorial notes

A well-absorbed chelated magnesium powder at a reasonable 200mg elemental dose per scoop; priced at a premium ($0.87/serving) versus typical magnesium glycinate powders on the market.
