The magnesium claim is reasonably supported: a randomized trial (Pouteau et al., 2018, n=264) found reduced perceived stress with magnesium supplementation in adults with low magnesium levels, and a long-term supplementation study observed a -32nmol/24h drop in urinary cortisol after 24 weeks — consistent with our own science base's magnesium entry (modest evidence, mainly useful when genuinely deficient). However, the detail about fat "storing... in the arms" directly contradicts the literature on cortisol excess: the recognized clinical picture (Cushing's syndrome) actually shows thinning of the arms and legs with muscle wasting, with fat concentrating in the face, trunk, and neck instead — the opposite of what the post claims. A minor factual error that doesn't invalidate the rest of the message, which is otherwise responsible and sells nothing. Verdict: mixed — the magnesium-cortisol link is real and moderately proven, the arm fat-storage detail is an error.
