Ready & Rested Magnesium Bisglycinate stands out with its high-strength formula, delivering 375mg of magnesium in just three capsules—the equivalent of 12 bananas or 9 cups of kale. It uses magnesium bisglycinate, a chelated form bound with the amino acid glycine, which allows for faster, more efficient absorption and minimises digestive discomfort often caused by other types. Unlike some magnesium supplements that compete with other minerals, Ready & Rested gets straight to work on the nervous system, helping calm the brain and regulate the body’s stress-response system.

Founded in 2013, Bare Biology is an independent, family-owned business driven by a team of women—mothers, daughters, and questioners—dedicated to crafting supplements they genuinely believe in and use themselves. Their independence serves as a superpower, enabling them to prioritise high-quality ingredients and exceptional customer service over fleeting trends or corporate profits. Transparency is at the core of Bare Biology's values, providing customers with clear information about their ingredients and sustainability practices. With a steadfast belief that women’s health deserves better, Bare Biology is committed to making a meaningful difference in the lives of women everywhere.
