️UK MADE TO HIGH QUALITY GMP STANDARDS, NEXT GENERATION NATURAL & ECO PULLULAN CAPSULES. Our Magtein Magnesium supplement is manufactured in the UK to GMP standards, ensuring the highest quality. Many cheaper supplements use capsules made from hypromellose which goes through heavy processing and produces non-environmentally friendly, harmful bi-products. Pullulan is the next generation in encapsulation, derived from tapioca and processed with water.
️SUPERIOR BIOAVAILABILITY. Many forms of magnesium are poorly absorbed by the body. Magtein Magnesium is the only high absorption, clinically studied magnesium of its kind, shown to effectively raise concentrations in the brain. What isn’t used by the brain is distributed to various areas of the body, where it assists in regulating heart and lung function, muscular contractions, hydration, and more than 300 other vital processes.
️RECOMMENDED BY EXPERTS. Leading neuroscientists including Dr. Andrew Huberman recommend consuming this specific form of Magnesium to help with initially falling asleep and for a deeper sleep. Magtein Magnesium is one component of the 'sleep cocktail' alongside Apigenin and L-Theanine, three supplements that work synergistically to improve sleep quality.
️OVER 92,000 TREES PLANTED AND COUNTING. Our supplements are not only good for you but also for the planet. We are proud supporters of Ecologi’s habitat restoration projects and plant a tree with every single order. We also contribute to rewilding efforts and carbon dioxide removal by funding the development of new blue carbon sinks.
️MAXIMUM POTENCY 2100MG MAGTEIN MAGNESIUM PER 4 CAPSULE SERVING. Our Magtein Magnesium supplement has the highest level of active ingredient on the market containing 2100mg per 4 capsule daily serving.
️GENUINE MAGTEIN MAGNESIUM, 100% VEGAN WITH NO FILLERS, BINDERS OR ADDITIVES. At Time Health we believe in clean nutrition which is why you won’t find any nasty stuff in our products including any binders, fillers or additives. Buyers should be aware Magtein is a very expensive ingredient and should therefore exercise caution before purchasing much cheaper alternatives. Verification can be made through the official distributor list published by Magtein.
️COGNITIVE SUPPORT INCLUDING LEARNING, MEMORY, MOOD, RELAXATION & SLEEP. Having sufficient levels of circulating magnesium in the brain is critical to cognitive health. Magtein Magnesium can effectively raise these levels resulting in improved recall, reduced age-related memory issues, and relaxation.
