Why I created this
In Melanie's words.
“Sleep and brain health are foundational. Sleep is one of the most powerful tools we have for long-term health, and brain health starts long before we wake up. When I learned about magnesium L-threonate and its studied role in supporting mood, memory and sleep, I knew it deserved its own formula. That's why I created Magnesium Nightcap: to provide targeted support for relaxation, restful sleep, and cognitive wellness.”

What makes it different
The decisions behind the formula.
This formula was created with carefully selected, high-quality ingredients, tested for purity and potency, and made without the problematic fillers Melanie personally avoids, including stearates and palmitates.
