Magnesium-L-Threonate

This formula contains Magtein™ because it is one of the only patented forms of magnesium-l-threonate.* Magtein™ may support learning and memory.*



Acetyl-L-Carnitine HCL

Involved in acetylcholine production, a neurotransmitter that plays a role in concentration.*

Coleus forskohlii

Widely used in traditional Ayurvedic medicine.

L-Phenylalanine

L-Phenylalanine is present in many foods (such as meat and dairy).

Vitamin B6

Contains important antioxidant properties that protect cells from damage during the production and metabolism of dopamine.*

L-Theanine

Green Coffee Beans

Supports a relaxed but alert state that is ideal for productive, focused activity - mental or physical.

B12 - Methylcobalamin

Vitamin B12 is crucial for the maintenance of normal, healthy cognitive function and memory recall through one’s lifespan.*

Folate

Folate contributes to the normal, healthy functioning of our brains.*

TMG

Commonly found in beets, spinach and shellfish, TMG or trimethylglycine is also known as Betaine.

L-Tyrosine

L-Tyrosine is converted into L-Dopa, the direct precursor to dopamine.*

Magnesium Glycinate

Glycine is an amino acid, attached to the magnesium molecule in magnesium glycinate. This is one of the highest-quality forms of magnesium available. We include magnesium glycinate because it helps support brain health and cognitive function.*

Magnesium Taurate

Magnesium taurate is the third form of magnesium inside MagTech®. Similar to glycine, taurine is also an amino acid. It plays a role in hundreds of chemical reactions, and in this context, attaches to the magnesium molecule as well. Paired with amino acids like this, magnesium has the potential to absorb effectively in the body and brain (based on in vitro research).


Magnesium-L-Threonate

This formula contains Magtein™ because it is one of the only patented forms of magnesium-l-threonate.* Magtein™ may support learning and memory.*

Acetyl-L-Carnitine HCL

We selected acetyl-L-carnitine because it promotes brain health.* It’s also involved in acetylcholine production, a neurotransmitter that plays a role in concentration.*

Coleus forskohlii

Forskolin is derived from the plant Coleus forskohlii which has been widely used in traditional Ayurvedic medicine. It has also has been extensively studied due to it’s ability to increase levels of intracellular cAMP molecules. Combined with Luteolin from Artichoke Extract, forskolin is theorized to synergistically increase the duration of cAMP in neurons.

L-Phenylalanine

L-Phenylalanine and L-Tyrosine are amino acid precursors to dopamine - both must be present in order for dopamine to be synthesized. L-Phenylalanine is present in many foods (such as meat and dairy), and is converted into L-Tyrosine in the body. In turn, L-Tyrosine is converted into L-Dopa, the direct precursor to dopamine.*

Vitamin B6

Vitamin B6 helps convert L-Dopa into dopamine and Vitamin C helps convert dopamine into norepinephrine (increasing alertness and attention).* Each of these also have important antioxidant properties that protect cells from damage during the production and metabolism of dopamine.*

L-Theanine

L-theanine is a natural amino acid found in green tea that removes the undesirable side effects of caffeine, creating long-lasting energy and attention without jitters, anxiousness, or a crash. A recent study from The Netherlands confirmed that "The combination of L-Theanine and Caffeine improves the cognitive performance and increases subject alertness." and that the combination "helps to focus attention during a demanding cognitive task."

Green Coffee Beans

Made with green coffee beans to support a relaxed but alert state that is ideal for productive, focused activity - mental or physical.

B12 - Methylcobalamin

Vitamin B12 supports healthy nerves and neural cell function.* A 2006 review of the roles of folate and Vitamin B12 and their impact on the nervous system highlighted the importance of adequate B12 levels for healthy neuronal function.* The same 2013 study mentioned above shows that Vitamin B12 is crucial for the maintenance of normal, healthy cognitive function and memory recall through one’s lifespan.*

Folate

Folate, Vitamin B12 and trimethylglycine are added to Dopamine Brain Food™ to lend support to the methylation process, and to aid in the generation of S-adenosyl methionine (SAM-E).* SAM-E is an amino acid that also plays an important role in the methylation process by helping to convert norepinephrine to epinephrine for use in attention-based activities.*

TMG

Folate, Vitamin B12 and trimethylglycine are added to Dopamine Brain Food™ to lend support to the methylation process, and to aid in the generation of S-adenosyl methionine (SAM-E).* SAM-E is an amino acid that also plays an important role in the methylation process by helping to convert norepinephrine to epinephrine for use in attention-based activities.*

L-Tyrosine

L-Phenylalanine and L-Tyrosine are amino acid precursors to dopamine - both must be present in order for dopamine to be synthesized. L-Phenylalanine is present in many foods (such as meat and dairy), and is converted into L-Tyrosine in the body. In turn, L-Tyrosine is converted into L-Dopa, the direct precursor to dopamine.

Vitamin C

Vitamin C helps convert dopamine into norepinephrine (increasing alertness and attention).* Each of these also have important antioxidant properties that protect cells from damage during the production and metabolism of dopamine.*

Saffron Flower Extract

We included Saffron Flower Extract because it is a potent botanical clinically studied to support a positive mood and emotional well-being.* It helps maintain optimal neurotransmitter balance to keep you feeling calm, clear, and driven.*

Zembrin® Kanna Extract

We included Zembrin® because it is a clinically-studied botanical extract shown to support executive function including cognitive flexibility, processing speed, and mental organization.* Zembrin® is a PDE4 inhibitor, helping to increase and prolong cAMP signaling.* This results in better focus, recall, and mental performance.*

    Sleeping through the night

    For the 1st time in years I'm sleeping through the night!! After so many nights of interrupted sleep, getting up every 2 hours to go to the bathroom, I'm finally able to go for several hours of uninterrupted sleep. It's a miracle!!
