You should start to feel the energizing effect of Boost Capsules within 45 minutes or so.
Re-Lyte Energy Boost Capsules contain 160 mg of caffeine from green tea extract. In our opinion, this is the perfect amount of caffeine to give you a balanced energy boost when you need it most. Since the caffeine comes in capsules, it’ll take a little bit longer to hit your bloodstream than when you drink a cup of coffee. You should start to feel the energizing effect of Boost Capsules within 45 minutes or so.
You’ll feel the strongest energy boost the first hour or two after the caffeine hits you and it will slowly decrease throughout the day. Caffeine has a half-life of between 4 and 6 hours on average, which means you’ll still have half the caffeine you consumed in your system 4-6 hours after you consume it. So 4-6 hours after taking 160 mg of caffeine in your Boost Capsules, you'll still have 80 mg left in your body. That’s a little less than the average cup of coffee.
Of course, when we created Re-Lyte Energy Boost Capsules, we wanted them to do more than just give you a quick energy boost. We wanted them to support healthy energy levels over the long term. So we also included two herbal adaptogens: maca root and ginseng root. These adaptogens help your body handle stress from all sources (physical, mental, or emotional) better. By improving your body’s resilience to stress, they can help reduce fatigue and restore your natural zest when taken consistently over time.
