-
Promotes healthy sleep-wake cycles.
-
Enhances next-day alertness while reducing grogginess and mental fog.
Sleep Breakthrough Capsules are designed to optimise sleep quality, helping you fall asleep faster, stay asleep longer, and wake up refreshed. This advanced formula supports natural melatonin production and balances sleep-related neurotransmitters to recalibrate your sleep-wake cycle.
Each capsule contains key cofactors that promote deep and restorative sleep without excessive melatonin supplementation. By supporting the production of serotonin, GABA, and other vital sleep hormones, Sleep Breakthrough Capsules help calm the mind, ease restlessness, and improve sleep efficiency.
A good night’s sleep is the foundation of peak performance, mental clarity, and overall well-being. Sleep Breakthrough Capsules work with your body's natural rhythms to enhance sleep quality, ensuring you wake up recharged and ready to take on the day.
