FAQ
This advanced formula includes two highly absorbable forms of magnesium (Magnesium L-Threonate and Magnesium Bisglycinate), L-Theanine to promote calm and focus, and our signature TruMarine® Collagen to support joint health, skin hydration, and tissue repair.
Magnesium L-Threonate is a unique form of magnesium that crosses the blood-brain barrier, allowing it to support cognitive health, memory, and focus. Unlike other forms of magnesium (like Magnesium Citrate or Magnesium Oxide), which mainly support muscle relaxation and digestion, Magnesium L-Threonate is designed to target the brain for enhanced mental clarity and cognitive function.
The blood-brain barrier is a protective shield that controls what substances can enter the brain. Magnesium L-Threonate is clinically shown to cross this barrier, allowing it to effectively support cognitive function, memory, and mental clarity.
The original blend contains Magnesium Citrate, which provides digestive support and gut health. This new blend is designed with Magnesium L-Threonate and Bisglycinate for enhanced mental clarity, relaxation, and recovery — making it ideal for focus, stress reduction, and restful sleep.
This blend is formulated to be gentle on the stomach, as it does not contain Magnesium Citrate — which can sometimes cause digestive discomfort. It’s a great option if you’re looking for calm and clarity without digestive side effects.
While this blend supports more restful sleep, it won’t make you drowsy. It can be taken any time of day — whenever you need a moment of calm, focus, or relaxation.

Magnesium L-Threonate
Magnesium L-Threonate is a highly absorbable form of magnesium that is clinically proven to cross the blood-brain barrier, supporting cognitive health and mental clarity. Unlike other forms of magnesium, it directly enhances brain function, memory, and focus, making it an excellent choice for relaxation and cognitive support before bed.
Magnesium Bisglycinate
Magnesium Bisglycinate is a gentle and easily absorbed form of magnesium. It’s bonded with the amino acid glycine, a neurotransmitter that promotes relaxation and calm. This form of magnesium supports muscle relaxation, reduces tension, and aids in better sleep quality.
L-Theanine
L-Theanine is a naturally calming amino acid that helps reduce stress and promotes relaxation without causing drowsiness. It encourages the brain to produce alpha waves, which help you feel calm and focused. This makes L-Theanine the perfect addition for easing into rest at the end of the day.

How Does Magnesium + TruMarine® Collagen Help with Overall Relaxation and Calm?
