| Bioavailability | Low — curcumin is ~3% of turmeric root, poorly absorbed alone | High — 95% curcuminoids, often enhanced with piperine or phospholipids | Curcumin Extract |

| GI Tolerability | Good — mild at culinary doses, may cause nausea at high doses | Good — well tolerated up to 8g/day in trials, occasional GI upset | Tie |
| Cost | $0.10-0.20/serving for turmeric powder capsules | $0.30-0.80/serving for standardized extract | Turmeric |
