Quick Facts

Who CanPrev Magnesium Threonate Is For

• Adults wanting magnesium support specifically for brain function, memory, and focus — not general muscle relaxation
• People over 40 thinking about cognitive aging and brain health maintenance
• Adults dealing with brain fog, mental fatigue, or memory concerns who want a clinically researched magnesium form
• Knowledge workers, students, and creative professionals wanting daily cognitive support
• Anyone with a practitioner-recommended need for brain magnesium support
• Adults who want CanPrev's practitioner-tier brand quality at a generous 120-capsule bottle size

Who this product is NOT for: If you mainly want magnesium for muscle relaxation, sleep, or constipation relief, magnesium bisglycinate or magnesium oxide are more appropriate — see CanPrev Magnesium Bisglycinate or Renew Life CleanseMORE respectively. If you want a more accessibly priced magnesium threonate, see Vitacheck Magnesium Threonate, one of our Vitamart Exclusive brands. If you take medications, especially blood pressure or heart medications, talk to your healthcare practitioner about magnesium supplementation. Magnesium threonate is the highest-cost magnesium form because of how Magtein is manufactured — if you don't specifically need brain magnesium support, other forms work better for the cost.

Vitamart's Take

CanPrev Magnesium Threonate is a magnesium supplement focused on cognitive support, including memory, focus, and mental clarity. This specialized form of magnesium is often chosen for cognitive wellness. A focused daily option for brain and cognitive support.

How CanPrev Magnesium Threonate Compares

CanPrev Magnesium Threonate vs Vitacheck Magnesium Threonate (Magtein)

CanPrev Threonate (this product): Practitioner-tier brand. Same Magtein® active ingredient. 120 capsules.
Vitacheck Magnesium Threonate: Same Magtein® active ingredient. Vitamart Exclusive brand at a more accessible price point. A fit if you want the same active ingredient at a lower-cost option.

CanPrev Magnesium Threonate vs Xymogen OptiMag Threonate

CanPrev Threonate (this product): Canadian practitioner-tier brand. Magtein® form.
Xymogen OptiMag Threonate: US-based premium practitioner-tier brand. Magtein® form. A fit if your practitioner specifically uses Xymogen, or for adults wanting the highest-tier brand positioning.

Magnesium Threonate vs Magnesium Bisglycinate

Magnesium Threonate (this product): Crosses the blood-brain barrier. Specifically for cognitive support. Higher cost per mg of magnesium.
Magnesium Bisglycinate: Well-absorbed general-purpose magnesium. Better for muscle relaxation, sleep, and overall magnesium needs. A fit for general magnesium support at a more accessible cost.

What Is Magnesium L-Threonate (Magtein)?

Most magnesium forms are similar in what they do once absorbed — they support muscle, nerve, and energy functions throughout the body. Magnesium L-threonate is the exception:

• Crosses the blood-brain barrier: Your brain is protected by a specialized barrier that controls what gets through. Most magnesium forms don't cross efficiently. Magtein is specifically developed to do so.
• Elevates brain magnesium levels: Clinical research with Magtein shows measurable increases in brain magnesium, which other magnesium forms don't achieve.
• Why this matters for cognition: Magnesium is involved in synaptic function (how brain cells communicate). Higher brain magnesium supports memory formation, learning, and synaptic plasticity.
• What it's NOT for: Magtein is not the most efficient form for muscle relaxation, sleep, or general magnesium needs. For those goals, bisglycinate works better at a lower cost.
• Magtein® brand: The Magtein® trademark identifies clinically researched magnesium L-threonate. Look for the Magtein® name on the label to ensure you're getting the researched form.
• Cost vs general magnesium: Magtein is the highest-cost magnesium form because of its specialized manufacturing. The higher cost is reasonable for brain-specific use but unnecessary for general magnesium needs.

How To Use

Adults: Take 3 capsules daily, divided between morning and evening, or as directed by your healthcare practitioner. Splitting the dose maintains steadier brain magnesium levels throughout the day. Take with food for best tolerance.

Effects build over time — most adults take magnesium threonate for 8-12 weeks before noticing meaningful cognitive support. Some adults notice better sleep within the first 2 weeks. Talk to a healthcare practitioner before use if you take medications, especially blood pressure or heart medications, or have kidney disease. Magnesium can interact with several medication classes.

Frequently Asked Questions

The 7 Forms of Magnesium

Magnesium is the same mineral, but the form it's paired with completely changes what it does:

• Bisglycinate: Gentle, well-absorbed, the daily all-purpose form. Sleep, stress, muscle. Doesn't cause loose stools.
• L-Threonate (this product): The only form proven to cross the blood-brain barrier. Specifically for cognition, memory, focus.
• Citrate: Good general absorption, gentle laxative effect at higher doses. Energy production.
• Malate: Bonded with malic acid. Supports cellular energy. Popular for daytime energy and fibromyalgia support.
• Taurate: Bonded with taurine. Cardiovascular support, calming.
• Glycinate: Similar to bisglycinate. Sleep and muscle relaxation focused.
• Oxide: Poorly absorbed for body magnesium but ideal for digestive cleansing and constipation relief (used in milk of magnesia and Renew Life CleanseMORE).

For cognitive support specifically, threonate is the targeted form. For general magnesium needs, bisglycinate is the all-purpose workhorse.
