The claims
Clams are tiny, chewy shellfish that contain a significant amount of nutrients. Clams are an excellent source of lean protein and vitamin B12. Twenty small clams provide over 700% of the daily value (DV) for vitamin B12 per serving. In a serving of 100 grams (3.5 ounces), small shellfish provide approximately 205 percent of the recommended daily allowance for iron. In addition, clams are typically an excellent source of antioxidants. The broth of steamed clams is also rich in vitamin B12, and 100 grams of canned clam broth provides between 113 and 588 percent of the daily value.
