Why we love it
  • High-potency, multi-form magnesium.
  • Essential for muscle and nerve.
  • Helps reduce tiredness and fatigue.
Main Highlights
  • ✔ WHY NUTRAVITA’S MAGNESIUM COMPLEX? - Discover the power of magnesium, with a carefully developed formula and high potency. Each daily serving of 2 high strength magnesium capsules provides 400mg of elemental magnesium, consisting of a combination of 5 high-quality types of magnesium, including: Magnesium Citrate, Magnesium Bisglycinate, Malate & Ascorbate & Magnesium Oxide. Our Magnesium capsules are a great alternative to magnesium glycinate tablets, powder, or oil spray.
  • ✔ WHY TAKE OUR MAGNESIUM? – Magnesium is also called "the mighty mineral" because the cells in our body depends on magnesium in regulating day-to-day metabolic reactions to help in the process of cell division and protein synthesis, to facilitate proper muscle and nerve function, and in maintenance of normal bones and teeth. Claims substantiated by EFSA (European Food Safety Authority). Boost your wellbeing with 240 easy-to-swallow, vegan capsules per bottle, offering a 4 month supply.
  • ✔ HOW DOES MAGNESIUM HELP ATHLETES, RUNNERS, AND DURING EXERCISE? – The role of magnesium especially during strenuous physical activities of people who train or work out on a daily basis is essential as minerals including magnesium are lost when we sweat. As substantiated by EFSA, intake of magnesium helps in the reduction of tiredness and fatigue, and in the maintenance of electrolyte balance and normal energy-yielding metabolism.

5% OffFree Shipping
Why we love it
  • Promotes quality sleep and energy.
  • Fast absorption due to chelation.
  • Strengthens muscle and heart health.
Main Highlights
  • HIGH STRENGTH VEGAN MAGNESIUM GLYCINATE - The recommended 300mg elemental magnesium per day (from 1500mg magnesium) makes these ideal strength magnesium tablets for women and men. Our capsules are vegan and vegetarian.
  • HOW TO USE VITABRIGHT MAGNESIUM GLYCINATE CAPSULES - Take 2 capsules a day with water. We suggest you take magnesium glycinate around 2 hours before you go to sleep. an amino acid that naturally occurs in foods.
  • WANT A MAGNESIUM GLYCINATE DRINK? Simply twist open your VitaBright magnesium capsules and tip the magnesium glycinate powder into fruit juice or, if you prefer, a mug of bedtime milk or cocoa before you go to sleep. This gives you a convenient magnesium glycinate liquid that's more economical than magnesium sachets.
  • CHELATED MAGNESIUM GLYCINATE FOR BETTER ABSORPTION - You want your magnesium tablets high-strength, but remember that high-absorption is equally important - otherwise it will just make you go to the toilet more often. VitaBright’s Magnesium Glycinate is chelated to the amino acid Glycine, forming a molecule of magnesium glycinate/bisglycinate. This means you absorb more, without the tummy trouble.
  • BRITISH MADE QUALITY - We have all our ingredients independently lab tested to guarantee their purity. VitaBright Magnesium Glycinate supplements contain no synthetic binders, no additives, no fillers, no preservatives, no bulking agents, no flow agents. We make our magnesium capsules here in the UK in pharmaceutical grade facilities, working to exacting GMP manufacturing quality standards. We're a British company and we are proud to have millions of loyal customers worldwide.

Why we love it
  • Highly absorbable, better absorption.
  • Gentle on the stomach.
  • Supports over 300 processes.
Main Highlights
  • HIGHLY ABSORBABLE: Magnesium glycinate (also known as magnesium bisglycinate) is the most bioavailable form of magnesium. Two glycine molecules are bound to each magnesium molecule through a process called "chelating," leading to increased solubility and better absorption.
  • GENTLE ON STOMACH: Standard magnesium supplements can cause stomach upset and laxative-like effects. The chelation process ensures that more of the magnesium powder is ready for use by the body without digestive disruption.
  • FULL-BODY BENEFITS: Magnesium is one of the best essential minerals for the body. It is involved in over 300 crucial biological processes, including sleep & relaxation, immunity, muscle soreness, metabolism and so much more.*
  • SMALL CAPSULES: Nobi’s small, 2-capsule servings are flavorless and easy to swallow. Each serving yields 400 mg of highly-absorbable magnesium, and each bottle contains 120 capsules.
  • MADE WITH YOU IN MIND: Magnesium Glycinate by Nobi Nutrition is Third-Party Tested and formulated without the top 9 allergens. It is manufactured in a facility that adheres to GMP guidelines.
