See the key ingredients behind 5 functional shots.
Start with each shot's purpose, then review 9 ingredient roles and representative research.
Functional shot structure
Start with the 5 shots people choose from.
Ingredients are grouped around the situations users see on the station.
Relax Shot
Built with L-theanine and taurine for an easy afternoon refresh routine.
Cutting Shot
Connects green tea extract and L-carnitine to a light care routine with exercise.
Amino Shot
Uses 9 essential amino acids and taurine for an easy before-and-after workout choice.
Vitamin Shot
Uses familiar nutrients like vitamin C and vitamin B for an everyday base routine.
Ingredient lineup
Review 9 key ingredients in plain language.
Exact formulas and amounts should be checked against product labels and installation materials.01Antioxidant vitamin
Vitamin C
Antioxidant vitaminA water-soluble antioxidant vitamin that anchors everyday condition routines.
Vitamin C is an essential nutrient that the body cannot synthesize on its own. It is linked to collagen synthesis, antioxidant defense, and iron absorption, and research continues around vitamin C transporters and oxidative stress in the brain and nervous system.
- Water-soluble vitamin
- Antioxidant defense
- Vitamin Shot line
VRINK context
A natural fit for the bright, foundational nutrition image of the Vitamin Shot.
02Water-soluble vitamin
Vitamin B
Water-soluble vitaminA water-soluble vitamin group involved in energy metabolism, nervous-system function, and daily nutrition routines.
Vitamin B refers to a group of related nutrients, including B1, B2, B3, B5, B6, B7, folate (B9), and B12. These vitamins act as coenzymes in carbohydrate, fat, and protein metabolism and are also discussed in relation to nervous-system function and cell maintenance, so VRINK frames them as foundational daily nutrition rather than a quick stimulant.
- Water-soluble vitamin
- Energy metabolism
- Daily nutrition routine
VRINK context
Easy to understand alongside Vitamin C as part of the Vitamin Shot's foundational nutrition context.
03Amino acid
L-Arginine
Amino acidAn amino acid connected to nitric oxide synthesis and pre-workout energy routines.
L-arginine is a building block of protein and a known substrate for nitric oxide synthesis. It has been studied in relation to endothelial function and exercise performance. VRINK presents it as part of a pre-workout ingredient context rather than as an exaggerated performance claim.
- NO precursor
- Pre-workout routine
- Booster Shot line
VRINK context
Works with caffeine and taurine to shape the energetic choice experience of the Booster Shot.
04Amino-acid-like compound
Taurine
Amino-acid-like compoundA broadly studied ingredient connected to neuronal excitability, osmoregulation, and cellular balance.
Taurine is not a standard protein-building amino acid, but it is found across tissues such as the brain, muscles, and heart. While familiar from energy drinks, VRINK treats it as a refresh ingredient with a different profile from the sharper stimulation of caffeine.
- Refresh
- Neural balance research
- Used across several shots
VRINK context
A supporting axis in different shot concepts such as Booster, Relax, and Amino.
05Essential amino acids
Essential Amino Acids
Essential amino acidsThe nine amino acids the body cannot make sufficiently and needs from diet.
Essential amino acids include histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. In exercise routines, they are a key ingredient group for understanding muscle protein synthesis alongside overall protein intake.
- 9 EAA
- Before and after workouts
- Amino Shot line
VRINK context
The core ingredient group that gives the Amino Shot its activity and recovery image.
06Botanical extract
Green Tea Extract
Botanical extractA plant-derived extract known for catechins and EGCG.
Green tea extract has been studied around catechins, EGCG, antioxidant activity, energy metabolism, and fat oxidation. Weight-management outcomes can vary by person and study condition, so VRINK presents it as a light balance ingredient for everyday routines.
- Catechins
- EGCG
- Cutting Shot line
VRINK context
Pairs with L-carnitine in the Cutting Shot to create a fresh balance image.
07Stimulant ingredient
Caffeine
Stimulant ingredientOne of the most studied ingredients for alertness and attention through adenosine receptor blockade.
Caffeine is a representative stimulant found in coffee, tea, guarana, and similar sources. It has been widely studied for attention, reaction time, and vigilance from low to moderate doses, but individual sensitivity, sleep, and timing can strongly affect how it feels.
- Attention
- Reaction time
- Check intake timing
VRINK context
Gives the Booster Shot its immediate energy image, while sensitive users should check total intake.
08Tea-derived amino acid
L-Theanine
Tea-derived amino acidAn amino acid found in green tea, often studied around calm focus and stress response.
L-theanine is often studied with caffeine because it may soften the sharpness of stimulation. Standalone studies have also reported results around stress-related measures and some cognitive tasks, so VRINK presents it as a relaxed refresh ingredient.
- Calm focus
- Green tea derived
- Relax Shot line
VRINK context
Works with taurine in the Relax Shot to create a balanced afternoon refresh image.
09Exercise routine ingredient
L-Carnitine
Exercise routine ingredientAn ingredient connected to the metabolic pathway that transports fatty acids into mitochondria.
L-carnitine is known for its role in long-chain fatty acid transport, and clinical studies also discuss exercise-induced muscle damage markers and recovery perception. VRINK presents it as one part of a balanced routine with exercise, not as a standalone weight-loss ingredient.
- Fatty acid transport
- Post-workout routine
- Cutting Shot line
VRINK context
Works with green tea extract in the Cutting Shot for a light management routine before and after exercise.
