Catfish Protein
When people think of seafood, salmon or tuna often come to mind, but catfish protein deserves a closer look.
Affordable, versatile, and surprisingly nutrient-rich, catfish offers lean protein that supports muscle repair, weight management, and overall health
. A single serving provides an impressive amount of protein along with vitamins like B12 and minerals such as selenium and phosphorus.
Whether you’re planning healthy meal prep, exploring high-protein fish options, or simply looking for a budget-friendly source of nutrition, catfish makes a strong addition to your diet.

A standard 3.5-ounce (100 g) serving of catfish delivers around 18 grams of protein, making it a solid lean fish option.
Most cooked fillets provide 15–26 grams of catfish protein, depending on size and preparation.
Alongside protein, catfish is low in calories and supplies vitamin B12, selenium, and phosphorus — nutrients that support energy, immunity, and bone health.
While not as high in omega-3s as salmon, catfish still offers a balanced nutrition profile at an affordable price point.
