Most Magnesium Is the Cheap Kind.

Magnesium L-threonate came out of research at MIT aimed at raising brain magnesium (Slutsky et al., 2010). FitNeuro leads with Magtein, the patented version, then adds two chelated forms, for 200mg of magnesium per serving and no oxide. Many people in the US get less magnesium than recommended (NIH Office of Dietary Supplements).

Who FitNeuro Is For

Built for people who want a better magnesium than cheap oxide.

  • Who It’s For

    • Anyone who wants Magtein magnesium L-threonate in their daily magnesium
    • People who want their magnesium from forms other than oxide

  • Who It’s Not For

    • Anyone who just wants a basic magnesium, since FitNeuro is built around Magtein
    • People expecting an instant jolt, since FitNeuro is made for consistent daily use

What’s Inside

Three forms of magnesium, each chosen for a reason. No cheap oxide making up the weight.

Magtein Magnesium L-Threonate

1g of the patented L-threonate form, developed from research at MIT. The hero of the formula.

Albion® Di-Magnesium Malate

Magnesium bound to malic acid, for everyday magnesium status.

TRAACS® Magnesium Lysinate Glycinate Chelate

A chelated magnesium bound to amino acids, for everyday magnesium status.

Formulated to exclude: wheat, gluten, corn, yeast, soy, animal and dairy products, fish, shellfish, peanuts, tree nuts, egg, sesame, ingredients derived from genetically modified organisms (GMOs), artificial colors, and artificial sweeteners.

Other ingredients include: capsule (hypromellose and water), hydroxypropyl cellulose, ascorbyl palmitate, and silica.

What to Expect From FitNeuro

Magnesium is a daily habit, not a single dose. Here’s the honest version.

  • Clock icon for the first phase

    From Day 1

    Start with three capsules a day. This is groundwork, not a jolt.

  • Calendar icon for the second phase

    Every Day

    Taken every day, FitNeuro helps ensure an optimal magnesium intake for overall health. Steady daily use is the whole point.

  • Layered blocks icon for the third phase

    Ongoing

    Many people in the US get less magnesium than recommended (NIH Office of Dietary Supplements), so the goal is to stay topped up every day.

How to Use FitNeuro

Frequently Asked Questions

What is magnesium L-threonate (Magtein)?

Magnesium L-threonate, sold as Magtein, is magnesium bound to threonic acid. It came out of research at MIT aimed at raising brain magnesium (Slutsky et al., 2010).

Why does the form of magnesium matter?

Forms differ in how well they’re absorbed. Forms that dissolve well in liquid absorb better, and several tend to be more bioavailable than magnesium oxide (NIH Office of Dietary Supplements). FitNeuro uses no magnesium oxide. It uses three other forms, led by Magtein.

What does FitNeuro do?

It helps ensure an optimal magnesium intake for overall health, with 200mg of magnesium per serving from Magtein and two chelated forms.

What are the other two magnesium forms for?

Albion di-magnesium malate and TRAACS magnesium lysinate glycinate chelate support your overall magnesium status. That matters because many people in the US get less magnesium than recommended (NIH Office of Dietary Supplements).

How much FitNeuro should I take?

Take three (3) capsules once or twice daily, or as directed by your healthcare professional. Three capsules provide 1g of Magtein and 200 mg of magnesium, so two servings a day provide 400 mg. The NIH upper limit for magnesium from supplements is 350 mg a day for adults. Consult your healthcare professional prior to use. Individuals taking medication should discuss potential interactions with their healthcare professional.

Will I feel FitNeuro right away?

No. FitNeuro isn’t a stimulant, so there’s no instant jolt. It’s made for consistent daily use.

Is FitNeuro vegetarian, and what does it exclude?

FitNeuro is vegetarian, though not vegan. The full exclusion list is on the label.

Can I stack Fitties products together?

Many Fitties products are designed to work together. Check each label so you don't double up on the same ingredient, such as caffeine or magnesium, and talk to your healthcare professional if you take medication. The Stack Builder can suggest a combination for your goals.

How are Fitties products made?

Every Fitties formula is manufactured in a GMP compliant facility. No low-grade shortcuts. Just ultra-premium ingredients, every one listed on the label.

What are the dietary and allergen details for each product?

Each product is different, and each product page lists what that formula is formulated to exclude, taken from its label. No Fitties formula uses artificial colors. If something doesn't fit your dietary needs, you'll know upfront.
