How it works:
B‑complex vitamins act as coenzymes in carbohydrate, protein, and fat metabolism to enhance energy production and appetite signaling in debilitated states.
Essential amino acids supply substrates for protein synthesis and tissue repair in recovery or chronic catabolism; taurine supports cardiac and retinal function and general vitality.
Iron supports erythropoiesis and oxygen transport; spirulina provides micronutrients and antioxidant support; potassium helps maintain neuromuscular and metabolic balance during refeeding or illness.
