Understanding Your Caffeine Tolerance
Your individual response to 125 mg of caffeine depends on factors like your weight, metabolism, and sensitivity. This dose may energize some, while regular users might feel little effect. Those sensitive may experience mild side effects, such as jitteriness or a rapid heart rate.
How 125 mg Compares to Other Beverages
To put 125 mg into perspective, it helps to see how it compares to other caffeinated drinks. This shows that 125 mg is a common dose, but the amount varies by source.
| Beverage | Serving Size | Approximate Caffeine (mg) |
|---|---|---|
| Brewed Coffee (Average) | 8 oz | 95–165 |
| Espresso (Double Shot) | 2 oz | 125–150 |
| Energy Drink (Standard) | 8 oz | 80–160 |
| Black Tea | 8 oz | 65–105 |
| Cola (12 oz Can) | 12 oz | 30–60 |
This table shows 125 mg is more than an average cup of brewed coffee but similar to a double espresso shot or a standard energy drink.
