We often treat sleep as a luxury—but when it comes to performance, recovery, and resilience, deep sleep is essential. Not just any sleep—restorative sleep. The kind that helps your body recover, your hormones reset, and your mind stay sharp.
At True Nutrition, we created the Deep Sleep Stack to support exactly that: better quality rest, grounded in science.
Sleep Quality Matters More Than You Think
When we’re sleep-deprived, stress hormones like cortisol surge—impairing recovery, digestion, and focus. And when we’re stressed? Sleep becomes even harder to come by—creating a never-ending cycle that leaves you foggy, inflamed, and under-recovered.
A 2023 study published in Frontiers in Psychology found that sleep quality was the strongest predictor of overall life satisfaction and subjective well-being, even more than total sleep time or sleep timing (AKA your schedule).* Simply put, how well you sleep matters as much, if not more, than how long.
The Deep Sleep Stack:
What’s Inside and Why It Works
This three-part stack is designed to help you fall asleep faster, stay asleep longer, and wake up refreshed. Each supplement plays a distinct, evidence-based role in enhancing sleep quality and promoting recovery.
Zinc-Mag
A potent mineral duo that promotes muscular relaxation, deeper sleep, and hormonal balance. Magnesium plays a crucial role in regulating melatonin and GABA activity, while zinc has been linked to enhanced sleep efficiency and improved immune health. [1]
L-Glycine
This amino acid helps lower core body temperature—signaling the body it’s time to sleep. Glycine has been shown to enhance subjective sleep quality and reduce next-day fatigue without sedating effects. [2]
Sleep Support Capsules
A synergistic blend of botanicals and amino acids, including GABA, 5-HTP, valerian, chamomile, lemon balm, and melatonin. This formula targets both the mind and body, promoting relaxation, calming the nervous system, and helping reset the circadian rhythm. [3]
The Sleep-Stress Loop—and How to Break It
When you’re not sleeping well, your body has to work overtime just to stay balanced. Cortisol rises, inflammation lingers, and mental clarity takes a hit. But when you prioritize rest, your system re-regulates:
- Hormones stabilize
- Muscles repair
- Stress levels drop
- Cognitive performance improves
The Deep Sleep Stack supports that full-circle recovery—so you’re not just getting by… you’re rebuilding while you rest.
How to Use the Stack
- Zinc-Mag: Take 2 capsules 30–60 minutes before bed
- L-Glycine: Mix 3g in water or tea before bed
- Sleep Support Capsules: Take 2 capsules 30 minutes before bedtime
Bonus: Add a scoop of Micellar Casein (or other slow-digesting protein) to your nighttime ritual to feed your muscles while you sleep.
Sleep Is Your Foundation
Better sleep means better recovery, stronger workouts, steadier moods, and a more resilient you. The Deep Sleep Stack is your nightly ritual for building strength while you rest.
