A Virtual Clinical Trial to Examine the Effect of Magnesium Choline Citrate on Cognitive Function and Anxiety in Healthy Adolescents and Adults

The goal of this clinical trial is to examine the effect of Magnesium Choline Citrate on cognitive function and anxiety in healthy adolescents and adults. The main questions it aims to answer are:

* What is the change in cognitive function, as assessed by the PROMIS Cognitive Function- Short Form 8a (≥18 years old) from baseline to Day 84 between Magnesium Choline Citrate and placebo? * What is the change in cognitive function, as assessed by the Pediatric Cognitive Function - Short Form 7a (8 - 17 years old) from baseline to Day 84 between Magnesium Choline Citrate and placebo?

Researchers will compare Magnesium Choline Citrate with placebo to evaluate its effects on cognitive function and anxiety symptoms. Participants will be asked to:

* Consume either Magnesium Choline Citrate or placebo for 84 days * Complete questionnaires (PROMIS Cognitive Function- Short Form 8a/Pediatric Cognitive Function - Short Form 7a, and PROMIS Emotional Distress - Anxiety - Short Form 8a/Pediatric Anxiety - Short Form 8a) * Complete a study diary weekly
