Vinco Magtein® Magnesium L-Threonate – Brain Energy & Mental Clarity Support (120 Capsules)
A high-strength, highly absorbable form of magnesium shown to cross the blood–brain barrier and support mental clarity, cognitive function, and brain energy - without digestive upset.
🧠 What Is It?
This isn’t your average magnesium supplement. Magtein® Magnesium L-Threonate is a patented, clinically researched form of magnesium that can actually reach your brain, where it helps regulate neural activity, support memory, and improve mental clarity.
Unlike other forms of magnesium, this one crosses the blood–brain barrier effectively - which is key if your focus, thinking speed, or mental stamina tend to crash midday. Each serving contains 2000mg of Magtein, giving you a strong daily dose in a well-tolerated capsule format.
⚡ How It Supports Energy & Focus
Mental fatigue, brain fog and scattered thinking are often tied to low magnesium levels in the brain - especially for those with ADHD or high cognitive demand.
Magnesium L-Threonate is ideal if you:
Struggle to stay focused for long
Experience “brain burnout” or mental fatigue
Feel wired but tired - overstimulated yet foggy
Want deeper, more restorative sleep to improve next-day motivation

✅ Why It’s ADHD-Friendly
ADHD brains burn through mental energy fast — and when magnesium is low, everything feels harder: memory, focus, emotional regulation, even sleep.
Magnesium L-Threonate:
Helps you stay mentally clear and emotionally steady
Supports restful sleep, which directly boosts next-day motivation
Doesn’t cause digestive upset like some magnesium forms do
If you’re feeling overstimulated but underproductive — this can help rebalance and re-energise your mind, without the crash or grogginess of other calming supplements.
