Magtein Magnesium L-Threonate

Thorne Cognitive Vitality

Three capsules provide 2,000 mg of Magtein magnesium L-threonate, delivering 144 mg of elemental magnesium. The form is the entire point: magnesium L-threonate crosses the blood-brain barrier more effectively than other magnesium compounds, which is what lets it raise magnesium levels in the brain specifically rather than only in the body.*

The magnesium here is bound to threonic acid, a compound derived from vitamin C. Magtein is patented and clinically studied, and has been shown to support neurological processes involved in memory formation, learning, relaxation, and healthy sleep regulation.* It is also NSF Certified for Sport, which is unusual for a cognitive product.

The Form

Getting Magnesium Into The Brain, Not Just The Body

Most magnesium supplements raise magnesium in circulation. Reaching neural tissue is a different problem, and it comes down to what the mineral is bound to.

🧠

Magnesium L-Threonate

Magnesium regulates neural pathways and supports healthy cognitive function, but getting it into the brain is the constraint. L-threonate crosses the blood-brain barrier more effectively than other magnesium compounds, so this form raises magnesium levels in the brain rather than only elsewhere.* The magnesium is bound to threonic acid, derived from vitamin C.

Frequently Asked Questions

Three capsules daily, or as recommended by your health-care practitioner. Note that the full serving is three capsules rather than one or two, so the 90-capsule bottle is a 30-day supply.

Those are two different measurements. 2,000 mg is the amount of the Magtein magnesium L-threonate compound; 144 mg is the elemental magnesium inside it. Elemental magnesium is the figure to use when comparing against other magnesium products, since every form carries a different proportion of it.

Because of where it goes. Magnesium L-threonate crosses the blood-brain barrier more effectively than other magnesium compounds, so it raises magnesium levels in the brain rather than only in circulation.* If your reason for taking magnesium is cognition, that is the difference. For sleep and muscle relaxation, glycinate is the usual choice; for digestive regularity, citrate.

Thorne's label carries the standard magnesium note: gas, bloating, or diarrhea may occur in some individuals taking magnesium supplements. The amount at which this happens varies by person and it resolves when the amount is reduced.

Thorne cites an estimate that around 75% of US adults fall short of the FDA's 420 mg recommended daily intake. Magnesium is involved in more than 600 enzymatic processes affecting cardiac, immune, musculoskeletal, nerve, urinary tract and gastrointestinal function, and low levels can present as muscle cramps, soreness, fatigue, poor sleep, or digestive irregularity.

This product is contraindicated in anyone with a history of hypersensitivity to any of its ingredients. If pregnant, consult your health-care practitioner before using this product. Thorne reports no known adverse interactions or contraindications as of the label's publication date.
