Improving Sleep Quality for Recovery: What I Learned Testing 3 Sleep Supplements

Let me start off with something with something that Dr. Jim Lavalle recently said on his Instagram account. Dr. Lavalle is the best resource I have when it comes to nutrition, supplements, and lifestyle. His expertise is second to none, and you should definitely follow him.

Sleep is When You Recover and Adapt

  • Training is the stress
  • Recovery is where adaptation happens
  • Most of that recovery occurs during sleep (growth hormone release, parasympathetic dominance, reduced nocturnal cortisol, slow-wave deep sleep, etc)

Sleep quality has a big effect at how well you adapt to the stress you apply in training.

So improving sleep quality isn’t just about:

  • Falling asleep faster
  • Sleeping longer
  • Feeling more relaxed

It’s about:

Improving the internal environment that drives recovery from training stress.

Not All “Sleep Aids” Do the Same Thing

Most sleep supplements get grouped into one category:

“Helps you sleep.”

But physiologically, they can work through:

  • Neurotransmitter modulation
  • Circadian rhythm support
  • Stress-response signaling

Each one targets a different bottleneck.

3 Common Sleep Bottlenecks

A. Cortical Hyperarousal 

(your brain stays on, thoughts keep cycling, you feel tired but mentally wired)

  • Racing thoughts
  • High sympathetic tone
  • Difficulty falling asleep

System involved:

→ Neurotransmitters (GABA / glutamate balance)

B. Circadian Rhythm Disruption

  • Trouble staying asleep
  • Irregular sleep timing
  • Poor sleep efficiency

System involved:

→ Serotonin / melatonin pathway

→ Sleep pressure regulation

C. Elevated Stress Physiology

  • Light sleep
  • Non-restorative sleep
  • Waking up unrefreshed

System involved:

→ HPA axis

→ Autonomic nervous system balance

Product Comparison Based on Mechanism

Thorne

 Deep Sleep Complex

Primary Role: Brain State Modulation

Mechanism:

  • L-Theanine → increases alpha brain waves
  • Apigenin → GABA-A receptor interaction
  • Maizinol → melatonin-like signaling

Functional Outcome:

  • Reduced sleep latency
  • Promotes transition into sleep
  • Calms cortical activity

Limitations:

  • Doesn’t directly influence sleep architecture
  • Doesn’t directly affect recovery physiology
  • More about initiating sleep than adapting from it

Designs for Health

 Insomnitol Chewables

Primary Role: Circadian + Neurochemical Support

Mechanism:

  • Myo-inositol
  • L-Theanine
  • 5-HTP

Functional Outcome:

  • Supports serotonin production
  • Supports melatonin precursor pathway
  • Improves sleep continuity
  • May reduce nighttime waking

Limitations:

Still primarily working through:

→ Neurotransmitter tone

→ Circadian rhythm timing

Designs for Health

 BioSleep Peptides

Primary Role: Stress-Response Signaling

Mechanism:

  • Hydrolyzed rice-derived bioactive peptides (PeptiSleep™)

Functional Outcome:

  • May influence HPA axis regulation
  • May improve autonomic balance
  • Supports parasympathetic dominance overnight
  • May improve slow-wave sleep depth

This becomes relevant when:

  • Training intensity is high
  • Recovery demand is elevated
  • Adaptation is the goal
