Active Ingredients & Science

Caffeine - The Classic Stimulant

Caffeine is a well-studied xanthine alkaloid that acts as a central nervous system stimulant. Caffeine is rapidly absorbed through the gastrointestinal tract and reaches its peak blood level within 30-60 minutes after intake. Caffeine is also known to enhance focus, reaction time, and mental clarity, making it a cornerstone in performance formulations.

EnXtra® (Alpinia galanga rhizome) - Extended Energy

EnXtra® is a patented extract from Alpinia galanga rhizome, a plant from the Zingiberaceae family commonly used in traditional Asian medicine. This ingredient is specifically designed to enhance and prolong the effect of caffeine. EnXtra® works by modulating how the body metabolises stimulants, resulting in a more stable and long-lasting energy curve compared to caffeine alone.

Zynamite® Mango Leaf Extract - Natural Energy Enhancer

Zynamite® is a standardised extract from Mangifera indica (mango leaf) containing 60% mangiferin, a bioactive polyphenol. Mangiferin is a powerful antioxidant naturally found in mango leaves and has been used in traditional medicine for centuries. Standardisation to 60% mangiferin ensures consistent potency from batch to batch.

Green tea is known for its high content of polyphenol antioxidants, particularly epigallocatechin gallate (EGCG), which constitutes 50% of this extract. EGCG is the most bioactive component in green tea and is well documented for its ability to support mental focus and cognitive function. EGCG works synergistically with caffeine to provide balanced stimulation without excessive nervousness. This combination is especially valued by users seeking mental clarity without jitteriness.

Kola Nut Extract - Traditional Energy Source

Kola nut is a natural source of caffeine and other alkaloids that have been used in traditional medicine and as an energy drink for centuries. The kola nut extract in this formulation provides additional natural stimulation and works synergistically with the other caffeine components. Including kola nut extract alongside other energy components creates a more complete stimulation profile that benefits from multiple natural sources.

Matcha Powder - Focus with L-theanine

Matcha powder also contains EGCG and other catechins that support mental clarity. When matcha powder is combined with caffeine, it creates a classic "focused energy" effect that many users prefer over caffeine alone.

Guarana Seed Extract (4:1) - Long-lasting Stimulation

Guarana seed is a natural source of caffeine known for its slower absorption and metabolism rate compared to synthetic caffeine. This 4:1 concentration means that four parts of guarana seed have been concentrated into one part extract, providing a potent and standardised dose. Guarana caffeine is gradually absorbed through the gastrointestinal tract, resulting in a more prolonged energy curve without the rapid peak and crash that can follow other caffeine forms. Guarana seed also contains tannins that may further affect absorption rate, making it an ideal component for sustained energy throughout the day.

Benefits & Uses

Five Unique Benefits Based on the Ingredients

• Multi-layered energy system: By combining caffeine from three different natural sources (caffeine, kola nut, and guarana seed) together with EnXtra® and Zynamite®, this formulation creates a multi-phase energy curve. This results in a more stable and prolonged energy level without dramatic ups and downs.
• This makes the product ideal for work requiring mental precision and endurance.
• Antioxidant protection from multiple sources: With EGCG from green tea, mangiferin from Zynamite®, and polyphenols from matcha powder and kola nut, you get a broad spectrum of antioxidants. These components work together to support cellular health during periods of intense mental or physical activity.
• This combination minimises the typical "coffee crash" many experience, enabling sustained productivity over longer periods.
• Synergistic formulation for performance: Each ingredient in this formulation is selected to work together with the others. This synergistic approach results in a more effective and well-rounded performance formulation than any single ingredient could provide alone.

Applications

The energy from the multi-layered caffeine formulation can support focus and endurance during training, while antioxidants from green tea and Zynamite® may aid recovery.

Work and study: For those needing sustained mental focus during long workdays or study sessions, this formulation offers stable energy without excessive nervousness.

Early mornings: The multi-layered energy profile makes this product perfect for kickstarting the morning. You get immediate energy to get going, followed by long-lasting endurance throughout the day.

Long workdays: For those working shifts or long days, this formulation can support energy levels without causing sleep disturbances later in the day if taken at an appropriate time.
