Futureproof your brain

Your brain is neuroplastic, meaning it's constantly wiring and rewiring your neural connections, called synapses, to learn new information and adapt to your world. Higher synaptic density in your brain corresponds with better memory and performance. 

Neuro Magnesi-Om uses Magtein magnesium L-threonate to increase synaptic plasticity and density in both the hippocampus (the brain's memory center) and prefrontal cortex (responsible for complex thinking) to support cognitive ability during aging.* 

Fight brain fog

The estrogen decline that hits in your 30s + 40s doesn't just affect sleep and sex—it causes your neurons to slow down and age faster, too. In your hippocampus, that slowdown turns into brain fog + forgetfulness. 

The Magtein magnesium L-threonate in Neuro Magnesi-Om reconfigures brain neuron connectivity to support learning and making memories, even as your neurons age.

A Note from Our Founder

“You take your brain for granted until it's taken away from you. And when you have to fight to get performance back, you start to think about protecting it long-term.”

Amanda Chantal Bacon, Founder

    Magnesi-obsessed

    Love starting my day with this. It hasn’t replaced my morning coffee yet but we’re halfway there.

    Sharper Focus, Better Workouts, Loving Neuro Magnesi‑Om

    I’ve been taking Moon Juice’s Neuro Magnesi‑Om for about two months now, and the difference in my focus and mental clarity is noticeable. I add the matcha flavor to my morning protein shake before my early workout, and by the time I’m finishing up, I can feel the shift, improved alertness, better concentration, and a smoother ability to process information.

    The matcha flavor actually tastes really good when I blend it with chocolate almond milk, which makes it easy to stay consistent. I plan to keep using it to see how much more progress I can make.

    Large jar for little contents, good flavour

    Good flavour, nice and light.

    I was really surprised when the jar arrived and it was only 1/3 full.

    I suppose it makes sense since there are only about 19 tsp in here (19.2 servings).

    At $4.64 a serving (or $3.39 if have a subscription), I have really high expectations for this.

    So far no noticeable benefits but it’s only day 3 ($13.92 ‘spent’).

    Good stuff

    Wish this wasn't so expensive for me, it works great. I still drink my morning coffee but I use this as my afternoon pick up when my mom brain starts to get a little mushy. It keeps me focused and energized which then keeps me in a better mood for the last half of the day .

FAQs

Why did you add extra caffeine when matcha already contains caffeine?

The combination of 50mg caffeine + 100mg L-theanine has been shown to improve both cognitive speed and accuracy. 1g matcha leaf powder has both caffeine and L-theanine, but in lesser quantities that vary from batch to batch—so we added
an extra 50mg caffeine (extracted from organic green coffee beans) and 100mg L-theanine to get full and predictable benefits.
When should I take this?

Because Neuro Magnesi-Om contains caffeine, we recommend taking Neuro Magnesi-Om in the morning or as an early afternoon coffee replacement.
What does it taste like and what gives it color?

Neuro Magnesi-Om’s color and taste come from matcha leaf powder. (Matcha is shade-grown, stone-ground green tea leaf.) The other ingredients are nearly tasteless. This product does not include any sweetener or artificial color.

When will I feel the effects?

Matcha, L-theanine, and caffeine have a near-immediate impact on alertness and energy; it’ll hit within 15–60 minutes. With daily use, the benefits of lion’s mane and Magtein magnesium L-threonate build over time.
How is Neuro Magnesi-Om different from Brain Dust?

Brain Dust is a blend of herbs + adaptogens for focus with a malty and bitter taste that alchemizes well with tea, coffee, chocolate, and milk. Neuro Magnesi-Om is a magnesium-mushroom matcha for instant focus and long-term cognitive health, and it can be enjoyed on its own in water or milk.
Is Neuro Magnesi-Om safe during pregnancy and breastfeeding?

We are not healthcare practitioners or providers, so we legally cannot provide you with any medical advice. If you are currently pregnant or nursing, we recommend consulting with a healthcare practitioner who is familiar with your medical history and current medications before consuming. You can find the ingredients of every Moon Juice product on each product page—feel free to use these as a reference when consulting with your healthcare practitioner.
Doesn't magnesium make you sleepy?

Not this one. Magnesium L-threonate feels totally different in your body than magnesium citrate, gluconate, acetyl taurinate, or glycinate, and it’s perfect for morning jumpstarts + afternoon boosts.
Can I use hot water?

Yes.
Can I take it in addition to my evening Magnesi-Om?

The recommended upper limit for magnesium is 420mg. If you take Neuro Magnesi-Om in the same day as Sleepy Magnesi-Om, you’ll stay under the RDA. If you take it with regular Magnesi-Om, you’ll be 43mg above the RDA.
