| Substance | Interaction | What happens |
|---|---|---|
| Fish Oil Triple Strength | Caution | Concentrated fish oil products deliver 2-3 g of EPA/DHA per softgel, which produces meaningful blood-pressure reductions on top of atenolol. The... details → |
| Garlic Extract | Caution | Aged garlic extract reduces systolic blood pressure by approximately 8 mmHg in hypertensives. Layered on atenolol, the combined effect can drive... details → |
| L-Arginine | Caution | L-Arginine modestly lowers blood pressure through nitric oxide-mediated vasodilation. Stacked with atenolol's beta1 blockade, the combined drop can... details → |
| Taurine | Caution | Taurine lowers blood pressure modestly and has direct heart-rate-lowering effects. Combined with atenolol, the effects can be additive, producing... details → |
| Coenzyme Q10 | Synergy | Like other beta-blockers, atenolol inhibits mitochondrial CoQ10-dependent enzymes, contributing to fatigue and reduced exercise tolerance. CoQ10... details → |
| Fish Oil | Synergy | Fish oil (EPA/DHA) at 2-3 g/day produces small reductions in blood pressure and lowers triglycerides, complementing atenolol's hemodynamic effects... details → |
| Melatonin | Synergy | Beta-blockers suppress nocturnal melatonin production. Atenolol, being beta-1 selective, has a moderate effect on melatonin suppression.... details → |
