What are liposomes? Magnesium l-threonate threonate is paired with the patented liposhell formula. High-quality liposomes are used as stable carriers to encapsulate and protect Magnesium l-threonate from being degraded by substances in the human digestive system. This allows Magnesium l-threonate to be effectively transported to the target location in the body where it is needed, so that Magnesium l-threonate can be incorporated into cells for optimal absorption.

BRAIN HEALTH: Magnesium is one of the key nutrients that are essential for brain functions and the nervous system. An adequate supply of magnesium is always needed for proper brain functioning. Magnesium L-Threonate is a highly bioavailable magnesium compound that can break through the brain barrier easily and provide an adequate supply of magnesium to brain health and its functioning.

BONE HEALTH: This magnesium l-threonate is fueled with vitamin D3 and K2. When they are consumed together it helps in increasing the bone mineral density and keeps your bone strengthened even if you are aged. They work together by activating the helpful protein by metabolizing the calcium in your body.

SUPERIOR- FORMULA: Our magnesium l-threonate is specially formulated using well-chosen ingredients that are 100% Non-GMO. They are completely free from gluten, soy, tree nut, dairy, egg, fish, wheat. This magnesium L-Threonate is expertly designed by scientists to enhance the bioavailability of this essential nutrient.

DOSAGE: This magnesium l-threonate supplement comes in a container that contains 60 softgels. In which two softgels constitute a dose of 2000mg Magnesium l-threonate. It is specially formulated for men and women since they lack brain performance due to aging. It is advised to take 2 softgels day after your meal.

Calcium & magnesium: Calcium is required for strong bones, teeth and cardiac function. Calcium not only builds strong bones and teeth but maintains bone density and strength. As well as protecting the body from stress, magnesium works with calcium to provide help to these same body systems and participates in more than 50 different biochemical reactions. That's why magnesium is so important to bone formation, nerve and muscle transmission, and energy production.

Key ingredients: This formula also includes other minerals, including manganese, potassium and zinc, which are also in the citrate form for better absorption and utilization by the cells, as they provide a valuable contribution to bone strength.* Vitamin D is included because it helps the body to absorb and properly use calcium.

Local, organic, and non-gmo: Because Natural Factors Farms are certified organic, we don't pollute the earth with pesticides and chemical fertilizers. We grow true species non-hybridized, non-GMO seeds, including many open-pollinated varieties. Growing locally also helps reduce the carbon emissions from overseas transportation, and keep jobs in the community.

Just the right size: We believe we need to be big enough to do it right. We are one of the only nutritional companies to have our own organic farms, our own extraction, encapsulation, and production facilities, our own labs and research facilities. We are also one of the few branded manufacturers of nutraceuticals in North America to have our own softgel encapsulation facility.

Third-party certified: Independently tested for GMOs and over 800 contaminants using advanced technology such as mass spectrometry to ensure purity and potency
