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.

Read the evidence (3 studies)See the 3 supporting studies
- Magnesium + T2D meta-analysis 2007 (286,668) (Magnesium)A meta-analysis of 7 cohort studies (286,668 participants) found each 100 mg/day increase in magnesium intake was associated with a 15% lower risk of type 2 diabetes. Studied at 100 mg. This product: 2001 mg.
- Magnesium + CVD meta-analysis 2019 (544,581) (Magnesium)Across 18 prospective cohort studies (544,581 participants), higher serum or dietary magnesium was linearly associated with 7-10% lower cardiovascular and coronary heart disease risk.
- Magnesium + vascular function 2020 meta-analysis (Magnesium)Oral magnesium supplementation improved flow-mediated dilation (endothelial function) in studies lasting longer than 6 months, particularly in older or overweight individuals.
How we scored this product Show the full breakdown
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.
Quick verdict
Why this scored this way
This Nootropics Depot Magtein Magnesium L-Threonate Capsules scores 7.4, making it a mid-tier product with both strengths and weaknesses. It delivers 2001mg of Magnesium, above the studied range of 200–500mg with grade A evidence (strong human trial data). Transparency is a clear strength (score: 9.0), with third-party testing and a public lab certificate. At $0.20/day it's priced well for what you get.
What drives the score up
- Dose-evidence score of 6.4 shows decent alignment with trial doses.
- Quality transparency of 9.0: tested by independent lab with a public lab certificate.
- Value score of 9.9 at $0.20/day.
- Community score of 9.4 with positive consumer feedback.
- Magnesium is dosed at the full research level with grade A evidence (strong human trial data).
What drags it down

What others say (unverified)
We aggregated external reviews. We didn't check their methodology. None of them are paid placements from us, but we can't guarantee the sources themselves received no product.
Nootropics Depot holds a 4.7/5 rating on Trustpilot from 2,404 reviews. Customers repeatedly cite third-party testing transparency and fast shipping.
Reddit users in the brand subreddit note that Magtein is a patented, licensed magnesium L-threonate, so most branded versions are functionally similar. Some commenters say Nootropics Depot's version is fairly priced for the dose, while others point to cheaper alternatives like Jarrow MagMind or Life Extension Neuro-Mag.
Examine's magnesium page notes decent evidence for blood sugar and blood pressure benefits but calls the sleep evidence surprisingly thin. A separate Examine FAQ says a magnesium and sleep meta-analysis found only a modest cut in sleep latency, with the authors calling current evidence insufficient for strong recommendations.
