| Magnesium | Tirzepatide (Mounjaro / Zepbound) | |
|---|---|---|
| Human evidence | ★★★★☆ | ★★★★★ |
| Legal status | OTC Supplement | Prescription |
| How it works | Cofactor for 300+ enzymes including ATP synthesis (ATP is biologically active as Mg-ATP), and a natural NMDA-receptor gate blocker (reduces neural excitation). Modulates the HPA axis, lowering cortisol. 50–60% of adults under-consume it… | Dual agonist of GIPR (GIP receptor) and GLP1R. GIP receptor activation in the hypothalamus and adipose tissue synergises with GLP-1, producing greater appetite suppression and fat loss than GLP-1 alone. |
| In plain English | A mineral your body uses in hundreds of reactions and burns through when you train and stress. Topping it up — especially glycinate at night — reliably improves sleep. | Hits two "I'm full" gut-hormone switches at once instead of one — so it works even better. SURMOUNT-1: 22.5% bodyweight lost, approaching bariatric-surgery territory. |
| Bottom line | Cheap, safe, most athletes are low. Glycinate before bed. | Currently the most effective approved obesity drug. |
| Availability | Available over the counter | Prescription only |
