Caffeine has a half-life of 5 to 7 hours. A coffee at 3pm means 50% of the caffeine is still active at 8 to 10pm. Even if you fall asleep, your sleep architecture is disrupted.
Studies show that caffeine consumed 6 hours before bed reduces total sleep by over 1 hour and significantly decreases deep sleep, even in people who report falling asleep normally. You do not feel the quality reduction.
SodaPeak is stimulant-free. You can take your gummy at any time without worrying about sleep interference. This is a deliberate design choice, not a limitation.
