PUMP / BLOOD FLOW
L-Citrulline
L-Citrulline is commonly used in pre-workout formulas for nitric oxide support, blood flow, and training performance applications.
INGREDIENT RESEARCH
INTELLEKT is built around transparent dosing, evidence-informed ingredients, and formulas that make sense on the label. This page collects research references for the key ingredients used across our performance, pump, hydration, and high-stim products.
HOW TO USE THIS PAGE
This page is not here to bury you in study links. It is here to show the thinking behind the ingredients we use and why transparent labels matter. A study-backed ingredient only means something when the dose is clearly disclosed.
No proprietary blends. No hiding doses behind “matrix” names. Every active ingredient should be clear.
Each ingredient should support a specific role: energy, focus, performance, hydration, pump, endurance, or recovery support.
We prioritize ingredients with meaningful sports nutrition research and practical use in real training environments.

PUMP / BLOOD FLOW
L-Citrulline is commonly used in pre-workout formulas for nitric oxide support, blood flow, and training performance applications.
ENDURANCE / PERFORMANCE
Beta-Alanine is commonly used to support muscular endurance and high-intensity exercise performance through its role in carnosine levels.
STRENGTH / POWER
Creatine monohydrate is one of the most researched sports nutrition ingredients and is commonly used to support high-intensity performance, strength, and power output.
ENERGY / FOCUS
Caffeine is widely researched for energy, alertness, focus, and exercise performance. Individual tolerance varies, so stimulant products should be used responsibly.
FOCUS / COGNITION
L-Tyrosine is commonly included in performance formulas for focus and cognitive support, especially in demanding training or high-stress environments.
POWER / OUTPUT
Betaine is commonly used in performance formulas for strength, power, hydration-related osmolyte support, and training output applications.
PERFORMANCE / HYDRATION
Taurine is commonly used in sports nutrition formulas for endurance, hydration-related support, and overall performance applications.
HYDRATION
Sodium, potassium, magnesium, and other electrolytes help support hydration, fluid balance, and performance during sweat-heavy training.
