What makes Magnesium Nightcap unique?

AvalonX Magnesium Nightcap contains a therapeutic dose of magnesium L-threonate, a special type of magnesium which specifically crosses the blood-brain barrier, to support sleep, mood, and memory. Unlike other forms of magnesium, magnesium threonate has been shown in clinical trials to reach significant levels in cranial tissue. AvalonX and MD Logic designed a special MCT formulation that eliminates unwanted additives and fillers, while also enhancing and maximizing absorption.

The final product is created in small batches for quality assurance and retested for the core four again upon completion. The final test is conducted by a third party before it is released for sale.

A bedtime routine staple

Quality product with 3rd party testing. I can feel confident that I am getting the magnesium so many of us lack with the added benefit of a solid nights sleep.

Wonderful product

Love a good product and I love a 2 in 1! I was taking magnesium and a sleep aid separately. Now I can get both in one. Wonderful. Plus it natural! Highly recommend
