SMART CAFFEINE

Smart Caffeine is a highly effective combination of L-theanine and Caffeine. 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, anxiety, or a crash.

Creates a relaxed yet alert state that is ideal for focusing and thinking clearly.

Synergistic Ingredients

Green Coffee Beans

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

L-Theanine

Creates long-lasting energy and attention without jitters.

Acetyl L-Carnitine

Research has shown that Acetyl-L-Carnitine may reduce mental and physical fatigue*.

Artichoke Leaf Extract

Artichoke Extract (Cynara scolymus) is an extract from the bulb of the artichoke vegetable.

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.*

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.

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."

Acetyl L-Carnitine

Acetyl-L-Carnitine is an immediate byproduct of metabolism that combines with CoA supplied by Vitamin B5 to produce Acetyl-CoA and Carnitine. At this stage in the process, this newly created Acetyl molecule is then able to join the Acetyl group of the acetylcholine molecule. Research has shown that Acetyl-L-Carnitine may also reduce mental and physical fatigue*.

Artichoke Leaf Extract

Artichoke extract contains Luteolin, a natural inhibitor of PDE4. PDE4 is an enzyme that breaks down cAMP molecules, messenger systems that relay signals in the brain. Studies have correlated lower levels of the enzyme PDE4 to significant increases in normal mental performance, including increased cognition, improved long term memory, increased wakefulness, and neuroprotection.

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.*
