Each serving provides 238mg of elemental magnesium in its most bioavailable form, magnesium bisglycinate, which is gentle on the stomach and helps support muscle relaxation, energy production, sleep quality, and heart health. Enhanced with 5mg of Bioperine®, it ensures superior nutrient absorption, making this the ultimate formula for optimal wellness and recovery.
Magnesium Bisglycinate + BioPerine®
A better-absorbed magnesium, formulated and third-party tested.
Magnesium is an essential mineral involved in over 300 biochemical processes in the body, including muscle function, nerve transmission, heart health, and energy production. Despite its importance, many people don't get enough magnesium from diet alone.
Why we chose magnesium bisglycinate
Not all magnesium is the same. Magnesium bisglycinate is a chelated form — the magnesium is bound to two molecules of the amino acid glycine. This form is better absorbed than magnesium oxide or citrate, and the glycine bond makes it gentler on the gut and less likely to cause a laxative effect.
What's in each serving
- 238mg elemental magnesium — supporting muscle relaxation, a calm stress response, and sleep.
- 5mg BioPerine® — a patented black pepper extract (standardised piperine), the world's only US-patented piperine ingredient, included as a bioavailability enhancer studied for supporting the uptake of co-administered nutrients.
Why our formula is buffered
Pure magnesium bisglycinate is only about 14% elemental magnesium by weight, so a useful dose would mean oversized or extra capsules. The grade we use is buffered so that 1080mg of magnesium bisglycinate delivers 238mg of elemental magnesium per serving, while the glycinate chelate stays the primary absorbed form. The elemental magnesium content is confirmed by Eurofins testing on every batch.
What it supports
- Energy — magnesium is a required cofactor for ATP production.
- Muscle recovery — supports normal muscle function and may help reduce cramps.
- Relaxation and sleep — magnesium plays a role in regulating the nervous system.
- Bone and structural health — magnesium supports calcium metabolism; a large share of the body's magnesium is stored in bone.
Tested twice, by Eurofins
Before manufacturing, each raw material is tested for contaminants and harmful substances. After production, the finished product is tested again to confirm accurate dosing. All testing is carried out through the independent Eurofins laboratory network.
A better-absorbed, gut-gentler magnesium — made and tested to a standard you can verify.
Frequently asked questions
What is magnesium bisglycinate and how does it differ from other forms?
Magnesium bisglycinate is a chelated form where magnesium binds to two glycine amino acid molecules. This bond improves intestinal absorption and reduces laxative side effects compared to magnesium oxide or citrate. It is the preferred form for individuals with sensitive digestion or magnesium deficiency.
What does BioPerine® do in a magnesium supplement?
BioPerine® is a patented black pepper extract standardised to 95% piperine, included as a bioavailability enhancer. It is studied for supporting the absorption of co-administered nutrients. In Vitalixir Magnesium Bisglycinate, 5mg BioPerine® is paired with the elemental magnesium for this reason.
How much elemental magnesium does each serving contain?
Each serving of Vitalixir Magnesium Bisglycinate delivers 238mg of elemental magnesium in bisglycinate form. This amount aligns with established adequate intake levels for adults and supports daily replenishment of magnesium depleted by stress, exercise, and poor dietary intake.
Can magnesium bisglycinate improve sleep quality?
Magnesium bisglycinate supports sleep by activating GABA receptors that calm the nervous system and reduce cortisol activity at night. Vitalixir customers report improved sleep within one to four weeks of consistent daily use, based on product reviews collected through June 2026.
How does magnesium bisglycinate support muscle recovery after exercise?
Magnesium is essential for ATP synthesis and muscle protein repair. Magnesium bisglycinate's high bioavailability ensures rapid cellular uptake post-exercise, reducing muscle cramps and accelerating recovery. Vitalixir reviewers report reduced post-workout soreness and cramp frequency after four weeks of use.
What does "300+ biochemical processes" mean for magnesium?
Magnesium acts as a cofactor in over 300 enzymatic reactions in the human body, including DNA synthesis, protein production, nerve transmission, and blood glucose regulation. This makes magnesium deficiency a systemic issue affecting energy, cognition, cardiovascular health, and hormonal balance simultaneously.
Is magnesium bisglycinate gentle on the stomach?
Magnesium bisglycinate is absorbed in the small intestine via amino acid transport channels, bypassing the osmotic mechanism that causes loose stools with magnesium oxide or sulfate. Vitalixir's bisglycinate formula is specifically selected for individuals who experience digestive discomfort with other magnesium forms.
What does Eurofins tested mean for Vitalixir Magnesium?
Eurofins is an accredited independent laboratory network. Vitalixir tests Magnesium Bisglycinate at two stages: raw material verification and post-production finished product analysis. This dual-stage testing confirms ingredient purity, label accuracy, and absence of contaminants before the product reaches consumers.
How does magnesium bisglycinate help with stress and anxiety?
Magnesium regulates the hypothalamic-pituitary-adrenal axis, which controls cortisol release under stress. The glycine component in bisglycinate has independent calming effects as an inhibitory neurotransmitter. Together, they support a measurable reduction in perceived stress and promote mental relaxation without sedation.
Does magnesium bisglycinate support heart health and bone density?
Magnesium regulates cardiac muscle contractions and maintains arterial elasticity, reducing hypertension risk. For bone health, magnesium activates vitamin D and assists calcium metabolism — approximately 60% of the body's total magnesium is stored in bone tissue. Adequate intake prevents both cardiovascular and skeletal deficiencies.
Who should consider taking magnesium bisglycinate with BioPerine?
Individuals with high stress loads, poor sleep, frequent muscle cramps, intense exercise routines, or restrictive diets are most likely to benefit. Adults over 40, women experiencing PMS symptoms, and people with type 2 diabetes — who show higher rates of magnesium depletion — are also well-suited candidates.
How long does magnesium bisglycinate take to show results?
Initial effects such as improved sleep onset and reduced muscle cramps are reported within one week for individuals with moderate deficiency. Systemic benefits including sustained energy, mood stabilization, and reduced anxiety typically require four weeks of consistent daily supplementation to become noticeable.
Can magnesium bisglycinate reduce period pain and PMS symptoms?
Magnesium reduces uterine muscle contractions and prostaglandin activity associated with dysmenorrhea. Clinical research indicates that magnesium supplementation reduces menstrual pain severity and PMS-related mood disturbances. Vitalixir customers have specifically reported relief from period cramps in product reviews.
What pack sizes are available for Vitalixir Magnesium Bisglycinate?
Vitalixir Magnesium Bisglycinate with BioPerine® is available in three pack options: single pack (₹749), pack of two, and pack of four (up to ₹1,419). Multi-pack options offer a lower per-unit cost and are suited for long-term supplementation of three months or more.
Does magnesium bisglycinate help with fatigue and low energy?
Magnesium is a required cofactor for ATP (adenosine triphosphate) production — the primary cellular energy currency. Without adequate magnesium, mitochondrial energy synthesis is impaired. Vitalixir Magnesium Bisglycinate replenishes this cofactor, supporting sustained energy levels throughout the day without stimulants.
Is Vitalixir Magnesium Bisglycinate pure or buffered, and why?
Vitalixir Magnesium Bisglycinate is chelated magnesium bisglycinate buffered with a small amount of magnesium hydroxide — a deliberate formulation choice. Pure bisglycinate carries only about 14% elemental magnesium by weight, so a meaningful dose would mean oversized or extra capsules. Buffering lets 1080mg of magnesium bisglycinate deliver 238mg of elemental magnesium in a capsule you can comfortably swallow, while the glycinate chelate continues to drive absorption and gut comfort. The magnesium hydroxide fraction is less bioavailable than the glycinate-bound fraction, which is why we disclose it openly rather than imply the formula is something it isn't.

Praveen M –
This one works like a magic pill coz not just my sleep quality and sleep cycle has improved but also my dream quality has been improved. I’m not sure whether it’s because of the magnesium but there’s a vivid difference in my sleep and dream cycle since I’ve started taking this supplement. Moreover, the rest and recovery has noticeably improved with this supplement and I would highly recommend to take this who trains everyday.
Dexter Goonethilake –
I’m a Rugby 7s player from Sri Lanka, competing in university, company, and other tournaments. After being away from rugby for some time, I recently got back into training, and the sessions were really intense. I started taking Magnesium BIS Glyconate + Bio Brine from Vitarix Nutrition, and I’ve noticed a big difference.
After tough practice sessions, when I’m exhausted and drained, I take one pill at night. It helps me sleep deeply and smoothly, and I wake up with much more energy for the next day’s training. It’s not a magical boost, but it feels like my body is finally getting something it was lacking before.
This supplement has definitely made recovery easier and my energy levels more consistent. I would recommend it to athletes or anyone who struggles with recovery and fatigue
Yeshi Dev –
Been taking this daily for over a month now and shockingly, I’m actually sleeping like a normal human being. If you enjoy tossing and turning at 3 AM, don’t try this, because it clearly ruins that routine. Simple, effective and apparently my ticket to finally outsmarting insomnia.
Rishika –
Upon recommendation from a nutritionist I gave Vitalixir Nutrition magnesium bisglycinate with bioperine to my 75 years old aunty as she’s been dealing with lumbar and cervical spondylosis also her femur neck was broken due to accident. Neuromuscular pain is too much that she had lost her ability to walk properly to do her daily activities. I can’t thank enough Vitalixir Nutrition your magnesium is a holy grail for her! She’s be en on the supplement only for 20 days and already able to manage her activites almost pain free !
Ashika –
I always have the worst periods cycle every month. the cramps has always been soo untolerable…and I can’t pass even one month of periods without taking painkillers. I was searching for an alternative without any side effects and I came accross the vitalixir magnesium. My friend suggested this as he saw good improvement in his sleep cycle. So I just blindly went ahead and got this but, this was unexpectedly also making my periods less painful . I found this very helpful as it worked well in reducing my cramps along with improving my sleep quality. Am relieved that I came accross this suppliment.Highly recommended for anyone who’s experiencing horrible period cramps.
Vivyn M –
Over the past year — from intense Strongman prep phases to recovering from a shoulder dislocation — Vitalixir Magnesium Bisglycinate has been a constant in my routine.
Through heavy training stress, muscle fatigue, poor sleep phases, and rehab recovery, it consistently supported better relaxation, reduced cramps, and improved sleep quality when recovery mattered the most.
Recovery isn’t just about training less — it’s about supporting your body better.
Vitalixir has definitely been a reliable part of that process for me.
