Surprising Magnesium Showdown: 7 Forms Supplie Test

We were intrigued by BIOptimizers Magnesium Breakthrough Supplement 4.0, with its promise of seven magnesium forms—Glycinate, Malate, Citrate, and more. We wanted to see if the blend lived up to its claims as a natural sleep and brain support. Our testing period spanned six weeks, and the results were mixed. While we noticed mild improvements in sleep quality and focus, the difference wasn’t dramatic enough to warrant a top-tier recommendation. The capsules are small and easy to swallow, but the lack of a clear dosing guide left us guessing. We appreciate the variety of forms, which target different biochemical pathways, but ultimately, we found the effects subtle. For those seeking a gentle, daily magnesium boost, it’s decent—but we’ve seen more impactful options.
