Protein is one of the three essential macronutrients and is composed of amino acids that the body uses to build and repair tissues. These amino acids are also involved in the production of enzymes, neurotransmitters, and many hormones. Without sufficient protein intake, these systems may not function efficiently.
From an endocrine perspective, protein plays a role in stabilizing blood sugar, supporting thyroid hormone conversion, and maintaining lean muscle mass, which is metabolically active tissue. Adequate protein intake can also help regulate appetite signaling hormones, contributing to better energy balance throughout the day.
Inadequate protein over time may contribute to symptoms such as low energy, poor recovery, muscle weakness, and increased susceptibility to illness. This is why protein intake is a foundational consideration in any hormone focused wellness plan.
