| Amphetamine (Adderall) / Lisdexamfetamine (Vyvanse) | Omega-3 (EPA/DHA) | |
|---|---|---|
| Human evidence | ★★★★★ | ★★★★★ |
| Legal status | Controlled | OTC Supplement, FDA Approved |
| How it works | Release dopamine/norepinephrine and block their reuptake via DAT (SLC6A3) and NET (SLC6A2), and reverse-transport through VMAT2 — potent focus/wakefulness, high addiction/cardiac risk. Vyvanse is a prodrug (abuse-resistant). | EPA and DHA incorporate into cell-membrane phospholipids and are converted to anti-inflammatory eicosanoids (resolvins, protectins). They activate PPARα and the fatty-acid receptor FFAR4 (GPR120), lower hepatic triglyceride synthesis, and… |
| In plain English | Floods the brain's focus/motivation chemicals — extremely effective for ADHD, extremely habit-forming and hard on the heart if misused. Schedule II. | These are the fish-oil fats your cell walls are built from. They calm inflammation and lower blood fats — most useful if you don't eat oily fish 2–3× a week. |
| Bottom line | — | Rare supplement with strong evidence across heart, joints, and brain. |
| 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.
