7 Mg Forms Tested: Surprising Calming Vitamins for Natural Sleep & Cognitive Support? We tried BIOptimizers Magnesium Breakthrough Supplement 4.0, a blend of seven magnesium forms-including glycinate, malate, citrate, and others-promising natural support for sleep and mental clarity. At first glance, the product's emphasis on "calming vitamins" felt a bit bold, but our experience revealed a more nuanced impact. The supplement's formulation, designed to target both relaxation and cognitive function, delivered a subtle yet consistent sense of calm without the usual grogginess of heavy sedatives. Over time, we noticed improved sleep quality and sharper focus, especially during high-stress days. The 60-capsule pack offers convenience, and the lack of harsh additives makes it appealing for those prioritizing purity. While not a magic pill, it's a thoughtful addition to a wellness routine, blending science and tradition in a way that feels authentic. Whether you're a skeptic or a believer in holistic health, this supplement deserves a closer look.
