The Sleep-Performance Connection

Elite athletes and high-performing professionals share a common secret: sleep is not a passive recovery period — it is the most anabolically productive time of the day. During deep sleep (slow-wave sleep, or SWS), the pituitary gland releases up to 70% of daily growth hormone output, driving muscle protein synthesis, tissue repair, fat metabolism, and cellular regeneration. REM sleep consolidates motor learning, procedural memory, and the neural adaptations that translate training into performance gains.

Xymogen® Sleep & Performance is a precisely formulated, clinically grounded supplement designed to support the quality and depth of sleep that active individuals need to recover, adapt, and perform at their best.

Key Ingredients & Clinical Evidence

Magnesium (as Magnesium Bisglycinate Chelate, Albion®) — 50 mg (12% DV)

Magnesium modulates the GABA receptor system — the primary inhibitory neurotransmitter pathway responsible for calming the nervous system and facilitating sleep onset. It also regulates melatonin production and suppresses the HPA axis, reducing the cortisol-driven hyperarousal that disrupts sleep in high-stress and high-training individuals.

This formula uses magnesium bisglycinate chelate (Albion®) — the most bioavailable and gastrointestinally tolerable form of magnesium available. Unlike magnesium oxide or citrate, bisglycinate chelate is absorbed via amino acid transport channels, bypassing the osmotic laxative effect common with other forms.

Proprietary Blend (DailyZz™) — 485 mg

DailyZz™ is a trademark of Kemin Industries, Inc., combining two botanicals with complementary mechanisms for sleep support:

Spearmint Extract (Mentha spicata, aerial parts)

Kemin's research on their spearmint extract demonstrates improvements in working memory, attention, and sleep quality in adults experiencing age-related cognitive decline. The active polyphenols — including rosmarinic acid and luteolin — exert antioxidant and anti-neuroinflammatory effects that support healthy neurotransmitter balance and sleep architecture.

Green Tea Extract (Camellia sinensis, leaves)

Green tea extract contributes L-Theanine — the amino acid uniquely found in tea leaves — which promotes alpha brain wave activity associated with relaxed alertness and facilitates the transition to sleep without sedation. The catechin antioxidants (EGCG) further support recovery by reducing systemic inflammation and oxidative stress from training.

Ashwagandha Extract (Withania somnifera, roots and leaves) — 120 mg | Shoden® | 35% Withanolide Glycosides

This formula features Shoden® — the highest-standardized ashwagandha extract commercially available, delivering 35% withanolide glycosides. This is significantly higher than the 5–8% standardization typical of most ashwagandha extracts, meaning a lower dose delivers superior clinical potency.

Shoden® has been studied in multiple randomized controlled trials demonstrating:

• Sleep quality: A double-blind, placebo-controlled RCT published in PLOS ONE found Shoden® significantly improved sleep onset latency, total sleep time, sleep efficiency, and non-restorative sleep scores compared to placebo.
• Stress & cortisol reduction: Shoden® significantly reduces serum cortisol levels, shifting the anabolic/catabolic balance toward recovery and muscle preservation during overnight rest.
• Hormonal support: Research demonstrates improvements in testosterone levels and DHEA-S in men supplementing with Shoden®, supporting the anabolic recovery environment during sleep.
• Anxiety reduction: Clinically validated reductions in perceived stress and anxiety scores (PSS, GAD-7), supporting the mental calm necessary for restorative sleep.

Who Should Consider Xymogen® Sleep & Performance?

• Athletes and active individuals seeking to optimize overnight recovery and adaptation
• High-performing professionals with stress-driven sleep disruption
• Those with magnesium depletion from intense training or high sweat output
• Individuals seeking a clean, stimulant-free sleep formula with premium ingredient sourcing
• Anyone looking to maximize the anabolic and restorative potential of their sleep

Pharmacist's Note

Xymogen® Sleep & Performance stands out for its ingredient quality — Albion® magnesium bisglycinate, Kemin's DailyZz™ blend, and Shoden® ashwagandha are all premium, clinically validated forms that most sleep supplements don't use. For athletes and active individuals who want to take their recovery seriously, this is our top recommendation in the sleep category. The 35% withanolide standardization of Shoden® is particularly impressive — it delivers meaningful cortisol reduction and sleep improvement at a lower dose than standard ashwagandha extracts.

Ashwagandha is not recommended during pregnancy or lactation. Please consult your pharmacist before use if you are taking sedative medications, thyroid medications, or immunosuppressants, as ashwagandha may have additive or interactive effects.
