If you notice some powder in your Magtein® bottle, don’t worry—it’s totally normal.
Magtein® (Magnesium L-Threonate) is an extremely fine powder, and during the encapsulation and bottling process, a small amount can naturally separate from the capsules or even leak out slightly over time. Because the powder is so fine, it can collect at the bottom or appear as residue inside the bottle.
This is completely expected and doesn’t affect the product’s quality, potency, or safety in any way. Every batch of Magtein® is tested to meet Momentous’ strict quality standards and is NSF Certified for Sport®.
