Apollo Magnesium L-Threonate — Magtein®, the magnesium form that reaches the brain, for memory, focus and sleep

Magnesium L-Threonate is a specific, patented form of magnesium (Magtein®) developed for one reason the common forms can't match: getting magnesium into the brain. Apollo's provides 144 mg of elemental magnesium across a daily dose, formulated to support cognitive function, a calm nervous system and restful sleep.

Per daily dose (3 capsules): Magtein® magnesium L-threonate, providing 144 mg of elemental magnesium. Vegan. 90 capsules (30-day supply).

What makes L-threonate different — it crosses the blood-brain barrier

Magnesium is a cofactor in hundreds of reactions, but the brain is protected by the blood-brain barrier, and most magnesium forms don't raise magnesium levels within the brain to any meaningful degree. Magnesium L-threonate was developed by researchers (originally at MIT) precisely to solve that: the threonate carrier allows magnesium to cross into the brain and lift magnesium in the cerebrospinal fluid, where it supports the density and plasticity of the connections between neurons. That is the whole point of this form — and why it's chosen for memory, focus and cognition rather than for muscles or bowels. See Brain Health.

Why the magnesium number looks smaller — and why that's the point

If you compare labels, L-threonate delivers less elemental magnesium per capsule than forms like citrate or glycinate. That isn't a shortfall — it's by design. The goal here isn't to load the body with the most magnesium possible; it's to deliver magnesium to the brain, which the threonate form does at a modest elemental dose. If your aim is muscle relaxation, cramps or general magnesium top-up, a different form is the better tool; for brain and cognitive support, this is the one. See Magnesium for the everyday forms.

Why Magtein® matters

Magtein® is the original, patented magnesium L-threonate raw material — the same form used in the research on this ingredient. Choosing it means you're getting the studied material rather than a generic imitation, which is exactly what to look for with a specialised nutrient like this.

Who it may suit

Adults supporting memory, focus and healthy cognitive ageing, people under sustained mental load, and those whose racing mind disrupts sleep and who want a calming, brain-directed magnesium.

How to take it

Three capsules daily in divided doses — one in the morning and two around two hours before bed — or as directed by your healthcare professional. Taking the evening portion before bed suits its calming, sleep-supportive role.

May support

• Memory, focus and cognitive function
• A calm nervous system and healthy stress response
• Restful sleep

Precautions

If you are pregnant or breastfeeding, take medication, or have a medical condition (including kidney concerns), speak with your healthcare professional before use. Excess magnesium may cause a laxative effect in some people. Always read the label and follow the directions for use. Keep out of reach of children.
