Muscle Relax+ delivers 400mg elemental magnesium per 2-capsule serving using a dual-form approach: 1200mg Magnesium Glycinate (providing 360mg elemental magnesium) combined with 200mg Magnesium Amino Acid Chelate (providing 40mg elemental magnesium). A systematic review by Boyle et al. (2017, PubMed 28445426) across 18 studies found magnesium supplementation significantly reduced anxiety and stress measures in mildly anxious adults. Each bottle contains 120 capsules (60 servings), NZ-manufactured, and selected with clinical guidance from Dr. Jun, Senior Chiropractor at Auckland Wellness Centre in Rosedale.

40mg elemental MgMagnesium is one of the most under-recognised nutrients in musculoskeletal and recovery health. It is essential for more than 300 enzymatic reactions in the body, including muscle contraction and relaxation, nerve signal transmission, ATP energy production, and protein synthesis. In clinical practice, muscle tension, poor sleep, and stress often arrive together, and magnesium deficiency is a common thread connecting them.
The problem with most magnesium supplements is form. Magnesium oxide, the dominant form in many supermarket products, has a bioavailability of approximately 4%. Magnesium Glycinate, the primary form in this formula, is chelated with glycine and has significantly superior absorption and gastrointestinal tolerance. The glycine component itself also has a calming neurological effect, which adds to the sleep and stress support profile.
Serving size: 2 capsules | Servings per container: 60 | Capsule type: clear vegetable capsule
| Ingredient | Compound Amount | Elemental Mg | Notes |
|---|---|---|---|
| Magnesium Glycinate | 1200mg per serving | 360mg (30% of compound) | Highly bioavailable chelate form; excellent GI tolerance; glycine component supports nervous system calming |
| Magnesium Amino Acid Chelate | 200mg per serving | 40mg (20% of compound) | Complementary chelate form; contributes to total elemental magnesium |
| Total elemental magnesium per 2-cap serving | 400mg | 360mg + 40mg = 400mg total elemental Mg | |

Magnesium is one of the most studied mineral supplements. The evidence below is drawn from systematic reviews and meta-analyses, the highest tier of clinical evidence available.
Store below 25°C in a cool, dry place. Keep out of reach of children. Do not exceed 2 capsules daily unless directed by a healthcare professional.
Magnesium deficiency shows up in clinical practice as a cluster of interrelated complaints: muscle tension, disrupted sleep, elevated stress response, and post-exercise soreness. Muscle Relax+ was developed for patients where these complaints overlap.
Muscle Relax+ is not a replacement for medical treatment. If you are managing a diagnosed sleep disorder or anxiety condition, consult your GP or healthcare provider before adding any supplement.
Magnesium supplements are ubiquitous, every pharmacy and supermarket in New Zealand carries them. The difference between products lies almost entirely in which form of magnesium is used and at what dose. Here is what sets Muscle Relax+ apart:

Muscle Relax+ provides 400mg of elemental magnesium per 2-capsule serving. This comes from two sources: 1200mg Magnesium Glycinate (yielding 360mg elemental magnesium at 30% elemental) plus 200mg Magnesium Amino Acid Chelate (yielding 40mg elemental magnesium at 20% elemental). Total: 360mg + 40mg = 400mg elemental magnesium per serving.
Magnesium Oxide has approximately 4% bioavailability, meaning most of it is not absorbed and instead passes through the GI tract, often causing loose stools at high doses. Magnesium Glycinate is chelated with glycine, resulting in significantly higher absorption and excellent GI tolerance at therapeutic doses. The glycine component also has a calming neurological effect, which adds to the muscle relaxation and sleep quality support profile of this formula.
Evening, 30–60 minutes before bed, is the most popular time, the glycine in Magnesium Glycinate has a calming effect that aligns with sleep preparation. However, daytime use is equally valid for muscle tension and stress support. The most important variable is consistency, take it at the same time every day.
Yes. Muscle Relax+ uses a clear vegetable capsule shell and is free from all animal products. It is suitable for vegetarians and vegans. It is also free from gluten, dairy, soy, shellfish, and nuts.
If you have kidney disease or reduced kidney function, consult your doctor before taking any magnesium supplement, including Muscle Relax+. Magnesium is excreted via the kidneys, and impaired kidney function may affect how the body handles supplemental magnesium.
One bottle of Muscle Relax+ contains 120 capsules, a 60-day supply at the recommended dose of 2 capsules per day. Current batch (2TZA200927) expires 01 September 2027.
Muscle Relax+ addresses muscle function, sleep quality, and stress recovery. Many patients combine it with Joint Comfort+ for joint and cartilage support, and NMN Boost+ for cellular energy. All three are available as the WIIP Bundle at 10% off individual prices.
WIIP Muscle Relax+ delivers 400mg of elemental magnesium per 2-capsule serving, 360mg from 1,200mg of magnesium glycinate plus 40mg from 200mg of amino acid chelate. This is 100% of the typical daily recommended intake.
Firoz & Graber (2001, PubMed 11794633) showed glycinate and citrate are 4-9x more bioavailable than oxide. Glycinate is gentler on the stomach and better absorbed for sleep and muscle support. Oxide has the lowest bioavailability and is best avoided for these applications.
A 2025 systematic review (Schuster et al., PubMed 39615118) found magnesium supplementation improved subjective sleep quality across multiple RCTs. Many WIIP customers report easier sleep onset. Take 1-2 hours before bed for sleep applications.
Yes, magnesium supports normal muscle function and contraction. Active New Zealanders use Muscle Relax+ post-exercise. The 2017 review (Zhang et al., PMC7468791) found magnesium supplementation improved exercise recovery markers.
Yes for most healthy adults. The TGA upper limit for magnesium supplementation is 350mg/day for chronic use, but elemental magnesium from food + supplement above this is safe in most cases. If you have kidney disease or take diuretics, consult your healthcare professional.
Most supplements are built by brands. Every WIIP formula passes two registered professionals before it earns the label: the clinician who sees what patients need, and the pharmacist who checks it is safe, correctly dosed, and honestly made.
Dr. Jun sees the same questions across the clinic bench every week. The formula starts from a real patient need, not a trend.
Jung Min Lee validates the form, the dose against the research, allergen and interaction safety, and the integrity of the label.
Formulated and manufactured in New Zealand, then encapsulated and bottled in Auckland. Transparent label, no proprietary blends.
His role: defines the clinical need and builds each formula at the dose he wants to give his own patients.
Her role: validates the form, the dose against the research, allergen and interaction safety, and the integrity of every label.
Per daily 2-capsule serve. No fillers hiding behind a "proprietary blend", because you deserve to know what you are taking and at what dose.
"Magnesium is all about the form. I checked Muscle Relax+ for what I would check at the counter: a chelated glycinate form, the true elemental dose stated clearly, and clean excipients. This is the magnesium I would point someone to for sleep and recovery."
Good to ask your own pharmacist or GP first if you take prescription medication or are pregnant or breastfeeding. Dietary supplement, not a medicine.
