Possibly for some people, but the evidence is not there to say that magnesium glycinate itself causes anxiety. Reviews of magnesium for anxiety are encouraging but small and of low quality. If you feel more restless or anxious after starting any supplement, the sensible move is to track what changed and speak to a doctor or pharmacist, not to push through.

What the research says

  • A 2017 systematic review (Boyle, Lawton and Dye) looked at 18 studies of magnesium and subjective anxiety. It found a suggested benefit in people vulnerable to anxiety, but said the quality of the evidence was poor and better trials were needed.
  • A 2024 review (Rawji and colleagues) examined 15 trials of magnesium for anxiety or sleep. Most showed improvement in at least one outcome, with minimal side effects reported, but small samples and very different doses and formulations limited firm conclusions.
  • We did not find a study showing that magnesium glycinate specifically causes anxiety. Our search covered two databases and was not exhaustive.

Why someone might feel worse anyway

Anxiety has many causes, and timing alone does not prove one. Other things that often change at the same time: caffeine, sleep, other supplements or medicines, stress, and expectation. Some people also notice stomach upset or restlessness with a new product, and the supplement is not the only possible reason.

What to do if you feel worse

  • Do not just push through, and do not guess.
  • Write down when you take it, the dose, and your caffeine, sleep, and other supplements or medicines.
  • Ask your doctor or pharmacist before you change or stop anything, especially if you take regular medication.
A supplement is not a treatment for an anxiety disorder. If anxiety is affecting your sleep, work, or relationships, please see a professional.
