Frequently Asked Questions

Why is Magnesium L-Threonate different from other magnesium forms?

Magtein is clinically shown to cross the blood-brain barrier, unlike most magnesium supplements which don't reach the brain effectively.

Should I take this in the morning or at night?

It can be taken in the morning for mental focus or in the evening for relaxation and sleep support — many people split their dose for balanced results.

What does the phosphatidylcholine do?

It's a phospholipid that supports neuronal cell membranes and healthy neurotransmission, working alongside Magtein for brain support.

Why choose sachets over the liquid bottle?

Sachets are travel-ready and pre-measured — no scoops or mixing needed, just tear and take a single serving on the go.
