Magnesium is often praised for its sleep and relaxation benefits, especially in the form of magnesium glycinate, which Moon Juice helped make popular. But according to Amanda Chantal Bacon, the brand’s co-founder and CEO, magnesium does much more than aid sleep. “It’s the master mineral,” she tells Vogue. “There are many types of magnesium, and each one affects how well your body absorbs it, which tissues it targets, and what extra benefits you get from its companion molecule. That’s what makes each form unique.”
When Bacon set out to expand on the success of Moon Juice’s popular Magnesi-Om powder—a key ingredient in the viral “sleepy-girl mocktail”—she thought about her own health journey. “I had long COVID in 2021, and for nine months I dealt with intense brain fog and memory issues,” she shares. “My mental energy was low, multitasking was hard, and I felt like my creativity had disappeared. It was scary, especially since cognitive decline runs in my family.” She notes that for some people, cognitive decline can begin as early as their late 20s or 30s, when mental sharpness typically peaks (though for others, this peak happens later). Perimenopause also plays a role. “Many know it’s a reproductive shift, but fewer realize it’s a neurological one too. Declining estrogen in the brain can slow neurons and speed up aging.”
That’s why Bacon created Neuro Magnesi-Om, a new supplement featuring magnesium L-threonate to help combat brain fog. “This form of magnesium crosses the blood-brain barrier more effectively than others,” she explains. “Think of that barrier as a filter that blocks toxins—it’s very selective. If not enough magnesium gets through, your brain can become deficient, affecting hormones and cognitive function.” Vanessa Coppola, a board-certified nurse practitioner, adds that Magtein (the branded form of magnesium L-threonate) was designed specifically to raise magnesium levels in the brain, which has been shown in studies to support synaptic density, learning, and memory. Unlike the original Magnesi-Om, which is best taken at night, this version is ideal for morning or afternoon use.

Why We Love It:
Moon Juice’s latest supplement, Neuro Magnesi-Om, combines two grams of magnesium L-threonate with organic mushrooms, ceremonial-grade matcha, and L-theanine to boost cognitive function, focus, and alertness. “I want you to have days where ideas flow easily, you clear your inbox, finish tasks, and still have the mental energy to read at the end of the day,” says Bacon.
Key Ingredients:
– Magtein magnesium L-threonate
– Lion’s mane mushroom
– Ceremonial-grade organic matcha
– L-theanine
Size: 84 g / 2.96 oz
To enhance the effects of magnesium L-threonate, the formula includes lion’s mane—an adaptogen known for supporting mental stamina, alertness, and mood—along with matcha, L-theanine, and polyphenols. “L-theanine encourages alpha brain waves, which reduce stress and improve focus,” Coppola notes. “When combined with a small amount of caffeine, it helps with attention, task-switching, and memory without causing jitters. Magnesium supports brain cell stability, sleep quality, and synaptic function, while lion’s mane may promote nerve growth. Together, these ingredients work on multiple pathways to support cognitive resilience and health.”This supplement combines brain-supporting lion’s mane with calming matcha and L-theanine. According to Coppola, these ingredients work together to support stress resilience, focus, and neuroplasticity.
The supplement comes as a fine powder that mixes easily into hot or cold water—or milk, for a latte-like drink. You only need one teaspoon. It tastes similar to matcha: slightly earthy, a little sweet, and more subtle than the brand’s fruitier options.
I was pleasantly surprised by how quickly it took effect. Within about 30 minutes, I felt ready to tackle my work. I breezed through emails, wrote faster than usual, and experienced a noticeable mental sharpness. It was the kind of brain boost I didn’t realize I needed—and the effects lasted for several hours. If I wanted to extend that clarity, I could take another dose; Moon Juice recommends using it once or twice a day.
“We want you to feel like a genius!” says Bacon. “Our mission is to encourage curiosity and help women take an active role in their health. Cognitive decline isn’t inevitable. The choices we make in our 20s, 30s, and 40s can help us stay sharp and present for longer.”
