Crab is a shellfish that delivers a strong protein profile alongside a concentrated array of micronutrients that are difficult to obtain in comparable density from land-based animal foods. It is notably high in vitamin B12, providing levels that support neurological health, methylation pathways, and red blood cell production. Crab is one of the most significant dietary sources of copper, a trace mineral essential for iron metabolism, connective tissue synthesis, and mitochondrial energy production via cytochrome c oxidase. It also supplies substantial zinc, which is critical for testosterone synthesis, immune defense, wound healing, and enzymatic activity across hundreds of physiological processes. Selenium is present at levels that meaningfully support antioxidant systems and thyroid function. Crab provides phosphorus and magnesium, both of which are involved in energy metabolism, bone structure, and neuromuscular function. Its fat content is low, with the lipids that are present including omega-3 fatty acids that contribute to cell membrane integrity and anti-inflammatory signaling. The protein in crab is complete, containing all essential amino acids in proportions that match human physiological requirements closely. Iodine is found in notable concentrations, supporting thyroid hormone synthesis. Crab meat contains folate, supporting one-carbon metabolism, nucleotide synthesis, and homocysteine regulation. The overall micronutrient density of crab makes it a valuable inclusion in a carnivore framework, particularly for supporting endocrine function and mineral repletion.
