Magnesium supplementation, including forms like magnesium glycinate and taurinate, has been shown in some studies to aid recovery from depression, particularly in individuals with magnesium deficiency and stress, with some evidence suggesting rapid improvement within about a week.
An incredible study found that supplementing with 125-300 mg of either Magnesium Taurinate or glycinate lead to a rapid recovery from even major depression and within just 7 days, especially in individuals with magnesium deficits and increased stress hormones.

What the Evidence Shows
Scientific research supports the role of magnesium in brain function and mood regulation, with deficiencies linked to depressive symptoms. Several studies, including clinical trials and reviews, indicate that magnesium supplementation can improve depressive symptoms, especially in patients with low magnesium levels or elevated stress hormones. The claim that doses between 125-300 mg of magnesium glycinate or taurinate lead to rapid recovery within 7 days aligns with findings from some smaller or preliminary studies that report symptom improvement in about a week.
However, the evidence is not universally conclusive or definitive for all cases of major depression, and larger randomized controlled trials are still needed to confirm the rapidity and extent of recovery. Additionally, while magnesium glycinate is well-studied for mental health benefits, specific data on magnesium taurinate is less abundant but suggests potential benefits related to stress response.
Overall, the claim is largely supported but should be interpreted with caution given variability in study designs and patient populations.
