Magnesium Nightcap

Magnesium L-threonate is a unique form of magnesium bound to threonic acid, which has been shown to have superior bioavailability and brain-penetrating abilities compared to other forms, significantly increasing magnesium in the brain. Studies have shown magnesium L-threonate may help support learning and memory, mood, stress levels, and sleep.*

Improve sleep quality*

Magnesium is involved in the regulation of sleep, and Magnesium L-Threonate supplementation may help improve the quality of sleep.*

Improve cognitive function*

Magnesium plays a crucial role in brain function, and studies have shown that magnesium L-Threonate supplementation may improve memory, learning, and overall cognitive function.*

Support mood*

Magnesium has been shown to have a calming effect on the nervous system, and studies have suggested that magnesium L-Threonate may be particularly effective in helping to reduce anxiety and depression symptoms.*

Magnesium L- Threonate has very specific cognitive properties and requires a high therapeutic dose for proper efficacy.

Recommended Use

As a dietary supplement, take 2 capsules per day, or as recommended by a healthcare professional. Please consult your healthcare professional before adding any health supplements to your diet.


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.

What is the recommended dosage?

As a dietary supplement, take 2 capsules per day, or as recommended by a healthcare professional.

Can I take Magnesium Nightcap with food or liquids?

Yes, Magnesium Nightcap can be taken with food or liquids.

Can I take Magnesium Nightcap with other supplements?

Magnesium Nightcap can be taken with other supplements unless otherwise indicated. Please consult a healthcare professional for personal medical advice.

Is your magnesium third-party tested?

Yes. The raw ingredients are first tested by our in-house lab before they enter the facility. We test the core four laboratory tests: purity, strength, compliance, and identity. 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. 

When should I take Magnesium Nightcap?

While Magnesium Nightcap can be taken at any time, it may be beneficial to take it within 30 minutes of eating a meal and with a full glass of water. Current clinical trials have been conducted with two doses split between the morning and evening.

Game changer in sleep

Melanie Avalon’s Magnesium Nightcap is a true game-changer when it comes to going to sleep, staying asleep and improved sleep quality. My Ōura ring tracked the improvement of my sleep when I started taking it. I take one every night and have the best sleep of my adult life! I highly recommend it!

Good night sleep magnesium

This really does help you have a good quality of sleep. I personally get into a deep sleep.
Sing to have more vivid dreams and can remember them in detail.

Love Magnesium Nightcap

Melanie Avalon’s products are clean and great quality. Love both the Nightcap and Magnesium 8!

Tina C. (Saint Augustine, FL)
The Magnesium Threonate is the real deal

I have absolutely noticed a difference since taking this. I love the Mag 8, I take it every night before bed and I sleep like a lincoln log. Don't be fooled by the word "Nightcap" you don't have to take this at night, it won't make you sleepy like the Mag 8. I feel more alert and my normal brain fog is gone and when I'm having an off day, I usually find it's because I didn't take my nightcap yet...it truly makes a positive difference. I'm a former paramedic so I'm very picky about what supplements I use and I have not been let down by any of the MD Logic/Melanie Avalon products.
