Does MagShape magnesium absorb better than other forms?

Lubrizol says MagShape raised magnesium blood levels higher and kept them elevated longer than oxide, citrate, and bisglycinate. For our Magnesium Supplementation community, this is an absorption claim—not proof of better sleep. Nutrition Insight interviewed Cecilia Izquierdo, a Lubrizol marketing manager, about the company’s human study. It compared MagShape with those three common forms. People in the study tried different forms at different times. The provided article does not give their ages, health details, or how many took part. Lubrizol reports higher and longer-lasting Magnesium blood levels with MagShape. But the article gives no size of the difference or exact duration. It also leaves out doses and detailed results. That makes it hard to judge how much the reported advantage matters. The company’s broader point is useful: absorption claims need a named comparison. Saying a product absorbs “better” means little without saying better than what. Lubrizol also says there are few human studies comparing forms directly. This report comes from the company promoting MagShape, rather than an independent review. Better absorption does not establish better sleep or muscle function. The study did not measure either outcome. Those possible benefits remain untested here. For members comparing notes, the useful details are the form, dose, timing, and tracked changes. Bloodwork and sleep records can keep that discussion grounded in your own numbers. They also help separate what changed from what a label promised. A personal pattern is worth sharing, without treating it as proof that one form works best. What differences, if any, have you tracked after changing magnesium forms?
