Can Magnesium L-Threonate Actually Help with Hair Loss?

Grace Gavilanes


Magnesium L-Threonate is the result of combining magnesium and threonic acid. This version of magnesium—yes, there are many versions—is highly bioavailable, meaning that it’s been found to pass through the blood-brain barrier more effectively. This is critical since this naturally occurring micronutrient is responsible for over 300 bodily functions related to nerve health, protein synthesis, energy production, and more.

Like many scientifically validated supplements, Magnesium L-Threonate has been having quite the moment in the wellness space, with many brands taking a stab at their own formula. We at Momentous take pride in our carefully curated portfolio of supplements—Magnesium L-Threonate included. It’s currently a bestseller and is loved by customers for its sleep and cognitive support.

Ahead, we take a closer look at the benefits of Magnesium L-Threonate, its surprising effect on hair loss, and how you can use this sought-after supplement in your daily wellness routine. 

What the Science Says About Magnesium L-Threonate’s Effect on Hair Loss

While Magnesium L-Threonate touts sleep and cognitive benefits that are backed by many clinical studies, one lesser-known benefit that’s been reported is its positive effect on hair loss.

Early studies have shown Magnesium L-Threonate can inhibit dihydrotestosterone (DHT)-inducible Dickkopf 1 (DKK-1), a gene associated with androgen-related balding, in cultured dermal papilla cells (DPCs). In simpler terms, Magnesium L-Threonate could help prevent baldness.

Magnesium L-Threonate plays an essential role in protein synthesis. This, of course, includes the production of keratin—a structural protein in hair. Additionally, since magnesium is involved in countless bodily functions, a deficiency in the micronutrient can cause a hormonal imbalance and reduced blood flow, which may, in turn, lead to hair loss.

Inflammation in the scalp has also been linked to hair loss, which may be detrimental to hair follicles and hair growth. Magnesium L-Threonate has been found to help reduce inflammation in the body, which may support the theory—backed by a few studies—that increasing your Magnesium L-Threonate intake can help support strong, healthy hair.

Research exploring the correlation between Magnesium L-Threonate and hair loss is still in the early stages. But seeing as the magnesium supplement’s popularity continues to rise, ongoing research will likely reveal even more details regarding the connection between Magnesium L-Threonate and hair health, as well as the other health benefits related to this revolutionary supplement. 

The Other Benefits of Supplementing with Magnesium L-Threonate

As previously mentioned, Magnesium L-Threonate boasts a bevy of health benefits that are unrelated to hair loss. They include improved cognitive function, sleep quality and duration, and decreased stress levels—a trio of benefits that directly impact hormonal health as a whole.

Improved Cognitive Function

Magnesium L-Threonate helps increase magnesium levels in the brain, which also helps increase synaptic density and promotes synaptic plasticity. The neuron-to-neuron communication that follows gets a boost, thus enhancing cognitive function.

This encapsulates memory, learning, focus, and attention. Magnesium L-Threonate remains one of the leading supplements and vitamins for helping to prevent dementia and Alzheimer's disease.

Enhanced Sleep Quality

If you’re dreaming of a more restful night’s sleep, Magnesium L-Threonate may be the answer. The nutrient regulates the activity of GABA, a neurotransmitter that works to calm the nervous system. Dr. Andrew Huberman, a lauded neuroscientist, host of the Huberman Lab podcast, and Momentous fan, explains this benefit: "Magnesium L-Threonate is associated with transporters in the body that bring more of it into cells, which helps people to feel drowsy and fall asleep."

Reduced Stress and Anxiety

Continued use of Magnesium L-Threonate is linked to the calming and quieting of the brain, which can support the aforementioned benefits of improved sleep quality and focus.

Speaking to Momentous Magnesium L-Threonate specifically, this magnesium supplement is formulated with 2 grams of Magtein® per serving. Magtein® is clinically proven to improve anxiety and depression symptoms.

Potential Side Effects of This Supplement

As is the case with other supplements, taking Magnesium L-Threonate may come with some side effects. While it’s generally well tolerated, taking high doses of the naturally occurring ingredient can cause digestive discomfort, like diarrhea and stomach cramps.

Taking Magnesium L-Threonate with a meal may help reduce or eradicate symptoms. If you’re still feeling unbearable side effects, we recommend stopping entirely or speaking with your licensed healthcare professional.

How We Recommend People Take Magnesium L-Threonate

Building a wellness routine that’s effective starts with consistency. Here’s how we recommend taking this supplement:

When to Use and Recommended Dosage:

Since one of the key benefits of Magnesium L-Threonate involves sleep, it’s imperative to take this magnesium supplement at night. In the case of Momentous Magnesium L-Threonate, we recommend taking 3 capsules 30 to 60 minutes before bedtime.

Onset Time:

While the effects of Magnesium L-Threonate, as they relate to deeper, higher-quality sleep, are usually felt within the first week of use, it takes around four weeks of supplementation for optimal improvements to be felt.

Expected Results:

Results aren’t standard across the board—they vary by individual—but customers have reportedly experienced enhanced focus, improved memory retention, and a sharper mental edge after 30 days of use.

It’s also important to note that you shouldn’t solely rely on supplements to support your health goals. Push what’s possible and commit to a daily regimen that also prioritizes a nutrient-rich diet as well as regular physical movement. Introducing a wellness supplement, in this case, will just serve as a welcome addition to an already balanced, well-rounded routine.
