L-Theanine 100mg + Caffeine 50mg | 60 Capsules

Enclosure for active ingredients, protects contents.

Capsule shells are typically made from gelatin (animal-derived protein) or hypromellose (HPMC, plant-derived cellulose polymer). They dissolve in the digestive tract, releasing the active ingredients. They protect the encapsulated ingredients from environmental factors like moisture and oxygen, and also mask unpleasant tastes or odors.

Bulking agent, binder, disintegrant.

Microcrystalline cellulose (MCC) is a purified, partially depolymerized cellulose. It's an inert, insoluble dietary fiber that is not digested or absorbed by the body. In supplement formulations, its primary role is as a binder to hold ingredients together, a filler or bulking agent to increase tablet size, and a disintegrant to help tablets break down in the digestive tract.

Bone structure, mineral source, bulking agent.

Di Calcium Phosphate is a compound containing both calcium and phosphorus, two essential minerals for human health. Calcium is the most abundant mineral in the body, primarily stored in bones and teeth, providing structural integrity. Phosphorus is the second most abundant, also critical for bone and teeth formation, energy metabolism (ATP), and cell membrane structure. In supplements, it acts both as a mineral source and a pharmaceutical excipient (filler/binder).

Lubricant, anti-adherent.

Magnesium stearate is a salt formed from magnesium and stearic acid, a saturated fatty acid.

Neurotransmitter modulator, promotes relaxation without sedation.

L-Theanine is an amino acid primarily found in tea leaves. It readily crosses the blood-brain barrier and influences brain wave activity, specifically increasing alpha brain waves, which are associated with a relaxed but alert state. It also modulates neurotransmitters like GABA (an inhibitory neurotransmitter), dopamine, and serotonin, contributing to its calming and mood-enhancing effects. When combined with caffeine, it can smooth out the stimulating effects of caffeine, reducing jitters and improving focus.

Central nervous system stimulant.

Caffeine primarily exerts its effects by blocking adenosine receptors in the brain. Adenosine is a neurotransmitter that promotes relaxation and sleepiness. By blocking these receptors, caffeine reduces feelings of fatigue and increases alertness. It also increases the release of other neurotransmitters like dopamine and norepinephrine, contributing to its stimulating effects and improved cognitive function.

Anti-caking agent, flow agent.

Silicon dioxide (silica) is a compound of silicon and oxygen. In powdered supplements, it's used as an anti-caking agent due to its high surface area and ability to absorb moisture. This prevents powders from clumping, ensuring that ingredients can be uniformly mixed and accurately dosed, and that powders flow smoothly during manufacturing. It is largely inert and passes through the digestive system unabsorbed.
