Varying Caffeine Content in Bloks Flavors
Understanding the caffeine content of Bloks is crucial for managing your energy intake, especially during long workouts or races. The amount is not uniform across all flavors; it depends on whether the specific chew is formulated with caffeine derived from sources like green tea extract.
Flavors with 50mg Caffeine per Serving
Some Bloks flavors are designed to provide a more significant caffeine boost. A standard serving of three chews in these flavors delivers 50mg of caffeine, which is comparable to a shot of espresso.
- Black Cherry: One of the most popular caffeinated options, the Black Cherry flavor offers 50mg of caffeine per three-chew serving, making it a favorite for endurance athletes.
- Other Potential Flavors: While Black Cherry is consistently cited, the specific lineup of caffeinated flavors can change. It is always best to check the product's packaging for the most accurate information.
Flavors with 25mg Caffeine per Serving
Other Bloks flavors offer a milder caffeine lift, with half the amount of the high-caffeine options. A three-chew serving provides 25mg of caffeine.
- Orange: This flavor is a classic choice for a moderate energy boost during exercise, containing 25mg of caffeine per serving.
- Tropical Punch: Another option for a lighter caffeinated effect, the Tropical Punch flavor also delivers 25mg per serving.
Caffeine-Free Flavors
For those sensitive to caffeine or training later in the day, Bloks also offers several caffeine-free alternatives.
- Mountain Berry: A popular choice that provides carbohydrates and electrolytes without any caffeine.
- Strawberry: Another flavor that focuses purely on fuel and electrolytes, without the added stimulant.
- Margarita: This unique flavor has an enhanced sodium level for electrolyte replacement but contains no caffeine.
Using Bloks Energy Chews During Exercise
Bloks are formulated for endurance activities and are best consumed with water. It's recommended to take half a packet (three chews) about 15 minutes before activity to raise blood sugar levels. During extended exercise, consuming 3 to 6 chews per hour is generally suggested to maintain energy. The small, portable packaging, known as the 'Fastpak,' allows for easy consumption with one hand, which is ideal for runners and cyclists.
Comparison: Bloks vs. Other Energy Sources
To put the caffeine content of Bloks in perspective, comparing it to other common energy sources can be useful. A standard 8-ounce cup of coffee contains approximately 95mg of caffeine, which is about double the amount in a full serving of a high-caffeine Bloks flavor.
Energy Source Comparison
| Energy Source | Caffeine Content | Primary Function | Ideal Use | Notes |
|---|---|---|---|---|
| High-Caffeine Bloks | 50mg per 3-chew serving | Quick, portable carbohydrates and a moderate caffeine boost | Endurance activities lasting longer than an hour | Easy to chew and digest; provides electrolytes |
| Energy Gel | Varies (often 25-50mg or more) | Very fast-absorbing liquid carbohydrates | High-intensity efforts where quick fuel is needed | Less mess than a gel with Bloks' packaging |
| 8oz Coffee | ~95mg (varies) | High caffeine stimulant | Pre-workout boost | Less ideal during activity; can cause stomach upset |
| Energy Drink | Varies widely (e.g., 100-300+mg) | High caffeine stimulant, sugar, vitamins | Quick, powerful boost (often not for mid-exercise) | Not recommended for most endurance athletes due to high sugar and potential gastrointestinal issues |
| Caffeine-Free Bloks | 0mg | Quick, portable carbohydrates and electrolytes | Consistent fuel without stimulant effect | Great for evening workouts or caffeine-sensitive athletes |
