Calcium Intake Calculator for Shellfish
Here’s a table showing the calcium content for various types of shellfish, based on common serving sizes (typically 3 ounces or 85 grams). Calcium values are approximate, as actual calcium content can vary slightly depending on the source, preparation method, and size of the shellfish.
| Shellfish Type | Calcium Content (per 3 oz/85g serving) |
|---|---|
| Shrimp | 33 mg |
| Crab (Blue, Cooked) | 92 mg |
| Lobster | 72 mg |
| Oysters | 100 mg |
| Scallops | 12 mg |
| Clams (Cooked) | 78 mg |
| Mussels | 84 mg |
| Squid (Calamari) | 32 mg |

Notes:
- Calcium content can vary based on whether the shellfish is fresh, frozen, or processed.
- Cooking methods (boiling, steaming, or frying) may slightly alter the calcium content.
