Lubrizol’s Magshape microcapsules deliver easily absorbed magnesium

Lubrizol is introducing a prototype formulation that includes the Magshape microcapsules magnesium ingredient in a fast-melt powdered stick for on-the-go post-work-out convenience.

This delivery system for magnesium can meet the needs of those seeking a more palatable format for getting their daily magnesium boost, according to Lubrizol. It can also help the B2B nutraceutical space by empowering supplement providers to create cutting-edge magnesium products that respond to market gaps.

The prototype samples are orosoluble sticks which deliver a single dose of 250mg elemental magnesium (upper limit of magnesium in a food supplement recommended by the European Food Safety Authority (EFSA)) neatly packed in a small 1.5g sachet of powder. This new prototype formulation presents another opportunity to utilise the Magshape magnesium ingredient in another format, in addition to tablets and chewables.

“Orosoluble powders that can deliver uniform palatable doses of magnesium require significant expertise to develop successfully,” explains Alan Connolly, Lubrizol R&D Manager. “It involves striking the right balance between particle size, solubility, taste, and flowability. Too large a particle size will result in poor dispersion in the mouth leading to a gritty, unpleasant texture. However, even the smallest particle will not behave as expected if it displays poor orosolubility.”

Also known as the mindfulness mineral, magnesium is emerging as a hero ingredient used to melt away stress and promote muscle relaxation. It is also EFSA approved for its crucial role in normal energy-yielding metabolism, normal muscle function, protein synthesis and electrolyte balance. It also contributes to a reduction in tiredness and fatigue making this mineral increasingly attractive for those leading active lifestyles, particularly athletes.

“Magnesium supplementation is widely embraced to bridge some nutritional gaps,” asserts Isabel Gómez, global marketing manager for Lubrizol Nutraceutical business. “However, obtaining the daily recommended dose can be burdensome, whether due to large pill sizes, their tendency to leave an unpleasant taste in the mouth, or gut discomfort, which consequently indicates poor absorption. Magshape magnesium ingredient was uniquely designed to ease the routine of supplementing by concentrating a potent dose of magnesium into the smallest serving while also being microencapsulated to ensure its absorption and minimise side effects.”

The proprietary microencapsulation technology in the Magshape ingredient provides micronised magnesium oxide particles with a wider surface area. This helps to deliver a stable source of magnesium that is more slowly absorbed by the intestinal tract and reduces common unpleasant side effects associated with magnesium supplementation.

The Magshape microencapsulated magnesium allows for versatile and more appealing consumption formats. Its fluid consistency and water dispersible coating makes it suitable for incorporation into a wide variety of food matrices.”

“Magshape ingredient is crafted from magnesium oxide which is the most concentrated form of magnesium. Its microencapsulation is designed to support gradual assimilation throughout the entire digestive system so that more gets into the blood stream to help replenish and maintain healthy magnesium levels in human cells and bones,” concludes Gómez. “A bioavailability study is in the pipeline to confirm its bioactivity in the body.”
