yu-Relax™
Consumer Medical Guide • Evidence Summary • Sources
Positioning: Nervous system shutdown • Muscle tension • Restless legs/spasms • Healthy inflammatory response • Sleep support • PMS tension
The “Off Switch” Formula (Brain + Body)
If you’re exhausted but your mind is still running, you’re not broken — you’re overstimulated. When the nervous system stays “on,” the body doesn’t fully relax: jaw tension, tight shoulders, restless legs, muscle spasms, PMS tension, and that wired-at-bedtime feeling can all stack up.
yu-Relax is designed to help you downshift. Not to numb you out — but to help your brain stop scanning and your body stop bracing, so you can actually release into rest.
What people typically notice:
-
“My jaw unclenched.”
-
“My legs stopped twitching.”
-
“I slept through the night.”
-
Overall: total relaxation (mind + muscles)
Best for:
-
Nighttime nervous system shutdown (racing thoughts)
-
Tension, tight muscles, spasms, restless legs
-
Occasional discomfort (back, injuries, “stress aches”)
-
PMS tension days and monthly discomfort patterns

Internal Outcomes (3-Week Free Trial • 157+ Women)
In a free product trial conducted over 3 weeks, 157+ women used yu-Relax (2 capsules per serving; taken throughout the day and/or at bedtime as needed) and reported outcomes related to relaxation and sleep.
Key outcomes:
77% reported improved ability to fall asleep faster and stay asleep longer.
90% reported a noticeable relaxation effect within 1 hour of use.
Note: These results reflect real-world self-reported outcomes (not a published randomized controlled trial) and are best interpreted as supportive user experience data.
Why Relaxation Fails (and What yu-Relax Targets)
Relaxation is a physiological state. When stress signaling stays elevated, the body stays in a guarded mode: tense muscles, heightened sensitivity, restless movement, and difficulty settling into sleep.
yu-Relax is designed to support multiple pathways involved in downshifting:
-
Nervous system downshift (quiet mind, calmer state)
-
Muscle relaxation (tension release, spasms)
-
Healthy inflammatory response (comfort support)
-
Stress adaptation (resilience + recovery support)
How to Use yu-Relax
Nighttime shutdown
2 capsules 30–60 minutes before bed.
Best for: racing thoughts, restless legs/twitching, body tension that blocks sleep.
Daytime tension / discomfort
2 capsules as needed during the day.
Best for: jaw/neck/shoulder tension, stress tightness, PMS tension days, occasional (back, neck, etc) discomfort/injuries.
Magnesium (Chelate) — the “unclench” mineral
Magnesium is a foundational mineral involved in muscle and nerve function, and it’s required as a cofactor for hundreds of enzyme systems in the body. For many women 30+, magnesium support can feel like the difference between trying to relax and actually being able to relax — especially when stress, sleep loss, intense workouts, and busy schedules are draining the body’s reserves.
Why a 30+ woman cares:
-
Helps the body move out of that “tight and twitchy” state (tension, spasms, restless legs patterns)
-
Supports a calmer nervous system baseline (so you don’t feel like you’re running on adrenaline)
-
Supports recovery when stress + depleted sleep are stacking up (work, kids, screens, training)
Magnesium is also widely recognized as important for energy production and normal metabolic processes, which matters when stress makes you feel worn down and wired at the same time.
Valerian Root Extract — deep relaxation + sleep onset support
Valerian is one of the most well-known traditional botanicals for sleep support and relaxation. NCCIH notes it is commonly used for sleep problems and discusses its safety profile and current evidence.
Why a 30+ woman cares:
-
When your brain won’t stop at night, valerian is a classic “turn down the volume” herb
-
Supports the transition into sleep (when you feel tired but can’t drift)
-
Often chosen by women who feel physically tense and mentally overstimulated at bedtime
This is a big part of the “nervous system shutdown” feel of yu-Relax — that exhale moment.
Passionflower Extract — “quiet the mind” support for nighttime overthinking
Passionflower is frequently promoted for sleep problems and anxiety, and NCCIH notes it has not been extensively studied overall, but provides safety and background context.
Why a 30+ woman cares:
-
Racing thoughts, mental loops, doom-scrolling brain, “can’t shut it off”
-
The kind of stress where you feel emotionally fine… but your nervous system is still buzzing
-
Those nights when you want to relax but your body feels wired
In yu-Relax, passionflower helps support the mental side of relaxation so the body can follow.
White Willow Bark Extract — comfort support + healthy inflammatory response
White willow bark has a long history of use for occasional discomfort and is commonly discussed in musculoskeletal comfort contexts. One reason women love formulas like this is because pain and sleep are deeply connected: if your back hurts, your hips are tight, or old injuries flare, it’s hard to settle into rest.
Why a 30+ woman cares:
-
Occasional back discomfort from desk posture, parenting, travel, workouts, or stress tension
-
“Inflammation-y” body days: sore, tight, achy, not recovering well
-
PMS-related body aches/tension patterns (where the body feels more reactive)
Important safety note: Because willow bark contains salicylate-related compounds, it carries aspirin-style cautions (including aspirin sensitivity/allergy considerations).
Devil’s Claw Root Extract — mobility + back/joint comfort support
Devil’s claw is often used for arthritis/joint issues and has evidence for modest improvements in low-back pain over the short term, with moderate evidence noted for osteoarthritis in certain areas (spine/hip/knee) in NCCIH’s musculoskeletal digest.
Why a 30+ woman cares:
-
“I can’t sleep because I’m uncomfortable” nights
-
Stress-held tension that turns into soreness (neck, back, hips)
-
Recovery support when you’re active but not bouncing back the way you used to
This is one reason yu-Relax can feel like more than a sleep formula — it supports the body component of shutting down.
AdPT® Adaptogen Blend
Ashwagandha Root — stress resilience + nervous system recovery
Ashwagandha is widely promoted for stress and sleep-related support, and NCCIH provides overview and safety notes (including that people should discuss use with a healthcare provider, especially with certain conditions/medications).
Why a 30+ woman cares:
-
You’re functioning… but it feels like your system is stuck in fight-or-flight
-
You’re sleeping, but not recovering
-
Stress is showing up in mood, patience, cravings, PMS intensity, and energy dips
In a blend like this, ashwagandha supports that deeper “resilience” layer — the ability to downshift and recover instead of living on stress hormones.
Rhodiola Root — stress adaptation + mental stamina (without pushing you)
Rhodiola is often promoted for increasing energy, stamina, and helping resist the effects of stress, and NCCIH provides safety/background context.
Why a 30+ woman cares:
-
The “burned out but still performing” season of life
-
Feeling mentally maxed out from constant decisions, work, parenting, and schedules
-
Wanting calm without feeling dulled or sedated
In yu-Relax, rhodiola supports balance: calming the stress response while still supporting mental steadiness.
Eleuthero Root — steady stamina + stress coping support
Eleuthero (often called Siberian ginseng) is traditionally used in stress and stamina contexts. Safety and interaction cautions are important with this herb (e.g., specific conditions and medication interactions), as noted by herbal safety references.
Why a 30+ woman cares:
-
You’re “on” all day and need your system to be more resilient
-
You want to feel less depleted by normal life stress
-
You want your body to stop reacting like everything is an emergency
In yu-Relax, this supports the longer-term “stress trained nervous system” recovery piece.
Cordyceps Mycelia — recovery support + vitality (traditional use)
Cordyceps has a long history in traditional Chinese medicine and is described in integrative medicine references for its traditional uses and safety considerations.
Why a 30+ woman cares:
-
When stress + sleep deprivation + workouts leave you feeling depleted
-
Wanting better recovery capacity (without stimulants)
-
Feeling like your body can’t keep up the way it used to
In yu-Relax, cordyceps is there to support a more resilient baseline so the body can actually restore itself.
Reishi Mycelia — nervous system support + “ease the body” tradition
Reishi is used in traditional Asian medicine to promote health and is commonly discussed in integrative settings (with attention to safety and interactions).
Why a 30+ woman cares:
-
Stress is stored in the body; you feel tense even when you’re “fine”
-
You want to feel more grounded at night
-
You want that calm, steady, resilient feeling rather than an on/off crash
Reishi supports that “settled” experience many women want at bedtime.
Gynostemma Whole — adaptogenic “balance” support (traditional use)
Gynostemma (often consumed as a tea in traditional contexts) has a long history of use and is discussed in review literature regarding traditional applications.
Why a 30+ woman cares:
-
You want your body to feel more balanced and less reactive
-
Stress and sleep issues are intertwined, and you’re tired of single-ingredient fixes
-
You want a formula that supports long-term regulation, not just a one-night knockout
EDS® Enzyme Blend
Amylase, Protease, Lipase, Cellulase — absorption + tolerance support
Digestive enzymes like amylase, protease, and lipase are commonly included in OTC enzyme supplements to support digestion; Johns Hopkins notes they’re used by many people for GI comfort concerns, and outlines how enzymes function in digestion.
Why a 30+ woman cares:
-
You want supplements that don’t feel “heavy,” nauseating, or hard to tolerate
-
Stress often shows up in digestion (tight gut, bloating, irregularity)
-
Better breakdown can support better use of what you’re taking
In yu-Relax, the enzyme blend supports a smoother experience and helps the body handle multi-ingredient formulas more comfortably.
Pulling it together: why this matters specifically for women 30+
This is the season where many women are:
-
carrying a nonstop mental load
-
waking up tired even when they sleep
-
feeling stress in their body (jaw/neck/hips/back)
-
dealing with PMS tension changes
-
recovering slower from workouts, travel, sitting, and life
yu-Relax is built for that exact reality: quiet the brain, release the body, support comfort, and help you drop into rest.
Ingredient Evidence (Human Research Summary)
1) Valerian (Valeriana officinalis) — sleep onset & sleep quality
Valerian has been evaluated across randomized controlled trials and systematic reviews for insomnia-related outcomes, with findings suggesting potential improvements in subjective sleep quality and related measures in some populations. Evidence quality varies across trials (common in botanical research). Sources: (1), (2)
2) Passionflower (Passiflora incarnata) — calming the mind & objective sleep parameters
A double-blind, randomized, placebo-controlled study in adults with insomnia disorder investigated passionflower using polysomnography (objective sleep testing) and validated questionnaires, reporting improvements in sleep parameters compared with placebo. Source: (3)
3) Magnesium (chelated) — muscle relaxation & sleep support (evidence mixed but promising)
Magnesium is essential for neuromuscular signaling and nervous system regulation. A systematic review found observational links between magnesium status and sleep quality. A randomized, placebo-controlled trial of magnesium bisglycinate (a chelated form) reported modest improvements in insomnia severity in adults with poor sleep quality. Sources: (4), (5)
4) White willow bark — comfort & healthy inflammatory response (musculoskeletal)
White willow bark (salicin-containing) has clinical research in chronic low back pain exacerbations using standardized extracts, showing benefit versus placebo in a randomized, double-blind design. Sources: (6), (7)
5) Devil’s claw (Harpagophytum procumbens) — short-term low back pain support
A Cochrane evidence summary reports that standardized devil’s claw preparations may be better than placebo for short-term pain improvements in low back pain in multiple trials. Source: (8)
6) Adaptogen blend — stress resilience & sleep quality support (ingredient-specific evidence)
Ashwagandha has a systematic review/meta-analysis of randomized controlled trials evaluating sleep outcomes versus placebo, reporting improvements in sleep quality/quantity in studied populations. Rhodiola has systematic review-level evidence in physical/mental fatigue and stress-related fatigue contexts (relevant to nervous system overdrive support). Sources: (9), (10)
Safety Notes
-
Aspirin/salicylate sensitivity: Contains white willow bark (salicin-related). Do not use if you have an aspirin allergy/sensitivity. (Source 7)
