What type of Magnesium is used in Stack?

Stack uses two forms of magnesium:

1. Magnesium L-Threonate
2. Magnesium Glycinate

These forms are chosen for specific reasons. Magnesium L-Threonate is noted to benefit the brain. This form of magnesium has been studied for its ability to cross the blood-brain barrier more effectively than other forms, potentially supporting cognitive function. Magnesium Glycinate is mentioned to benefit relaxation and sleep. This form is often chosen for its high bioavailability and gentleness on the digestive system. It's also known for its calming properties.
