Vitamins and minerals are essential micronutrients that your body needs in small amounts to function properly. They play vital roles in everything from bone health and immune function to energy production and blood clotting. While a balanced diet is the best way to obtain these nutrients, deficiencies can occur due to poor dietary intake, malabsorption issues, or certain medical conditions.

Vitamin D is crucial for bone health, as it helps the body absorb calcium. It also plays a significant role in immune function and muscle health. Vitamin D deficiency is common, especially in areas with limited sunlight exposure, and can lead to weakened bones (osteoporosis) and an increased risk of fractures.

Vitamin B12 is essential for nerve function and the production of red blood cells. A deficiency can cause anemia, fatigue, and neurological symptoms like numbness and tingling in the hands and feet. This deficiency is more common in older adults and those following strict vegetarian or vegan diets.

Iron is a vital mineral needed to produce hemoglobin, the protein in red blood cells that carries oxygen throughout the body. Iron deficiency is the most common cause of anemia, leading to fatigue, weakness, and pale skin. A complete iron panel typically includes serum iron, total iron-binding capacity (TIBC), and ferritin.

Other important minerals often tested include Calcium and Magnesium, which are essential for bone health, muscle function, and nerve signaling.
