Ephedrine (EC/ECA stack) vs Magnesium
Both are used for cardiovascular. Here's how they compare on human evidence, mechanism, safety and availability — in plain English.
| Ephedrine (EC/ECA stack) | Magnesium | |
|---|---|---|
| Human evidence | ★★★★☆ | ★★★★☆ |
| Legal status | Prescription, Controlled | OTC Supplement |
| How it works | Non-selective adrenergic agonist and norepinephrine releaser (ADRB1/2/3); centrally suppresses appetite and peripherally raises thermogenesis. Synergistic with caffeine (which blocks the negative-feedback of adenosine and… | 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… |
| In plain English | Flips your "fight or flight" system on a little, which curbs hunger and burns more calories. Effective but raises heart rate and blood pressure — restricted for that reason. | 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. |
| Bottom line | Genuinely works; cardiovascular risk got it pulled from most shelves. | Cheap, safe, most athletes are low. Glycinate before bed. |
| Availability | Controlled substance | Available over the counter |
Which is better for cardiovascular?
Both carry a comparable human-evidence rating (★★★★☆). Choose on mechanism fit, side-effects, availability and cost rather than evidence strength alone — they work through different mechanisms.
