Rubicon Raw Raspberry and Blueberry: The Caffeine Breakdown
For those needing a precise figure, a standard 500ml can of Rubicon Raw Energy in Raspberry and Blueberry flavour contains 160mg of caffeine. This translates to a caffeine concentration of 32mg per 100ml. This is a key piece of information for anyone monitoring their intake or comparing it to other energy drinks or caffeinated beverages.
Where the Caffeine Comes From
Unlike many energy drinks that use synthetic caffeine, Rubicon Raw prides itself on using natural caffeine derived from green coffee beans. The product also lists added guarana extract and ginseng root extract, which are often included in energy products to provide an extra boost. The natural sourcing aligns with the product's emphasis on containing 20% real fruit juice.
Other Notable Ingredients
Beyond caffeine, the drink includes a mix of ingredients that contribute to its flavour and energy-boosting properties:
- Fruit Juices: The Raspberry and Blueberry flavour features a blend of fruit juices from concentrate, including apple, grape, blackcurrant, raspberry, lime, blueberry, and passion fruit.
- Vitamins: A full 500ml can contains 100% of the recommended daily intake for several B-vitamins, including Niacin (B3), B6, and B12. These vitamins contribute to normal energy-yielding metabolism and the reduction of tiredness and fatigue.
- No Artificial Colours: The drink relies on natural flavourings and avoids artificial colours.

How Caffeine Provides Energy
Caffeine is a central nervous system stimulant that works by blocking adenosine, a neurotransmitter that promotes relaxation and sleepiness. By blocking adenosine, caffeine can increase alertness and reduce the perception of fatigue. In addition to caffeine, the B-vitamins in Rubicon Raw also contribute to the body's natural energy production processes.
Conclusion
To summarize, a single 500ml can of Rubicon Raw Energy Raspberry and Blueberry delivers 160mg of natural caffeine, derived from green coffee beans. This provides a substantial energy boost, supplemented by guarana, ginseng, and B-vitamins. Consumers should pay close attention to the high caffeine content and follow the on-can warnings regarding responsible consumption, especially for sensitive groups.
