Overview
Magnesium L-threonate is the form used here, supplied as the branded Magtein and sold by Sports Research in a vegan capsule. The listing frames it around brain health, memory, focus and restful sleep.
The reason to look at it is the specific threonate form that is marketed for cognitive uses, in a clean vegan capsule. The limitation is that the large milligram figure is a total and the elemental magnesium amount is not listed.
Who it's for
A person who has already chosen the L-threonate form and wants a branded version in a vegan capsule will find it straightforward. Those who simply need a general magnesium, or who have kidney disease, should look at other forms or ask a doctor.
Pros and cons
- Branded Magtein form
- Non-GMO and gluten free
- Cognitive health focus
- Elemental magnesium not listed
- Serving size not listed
- Cognitive claims lack data
Performance notes
L-threonate is a form of magnesium that makers say reaches the brain, which is why it is sold for memory and focus. Only part of the compound weight is elemental magnesium, so the headline figure overstates the mineral itself. The label states the serving.
