Nutrient Analysis

25-OH vitamin D is the storage form of vitamin D that the body produces in the liver from vitamin D formed by sunlight or food. Vitamin D supports calcium absorption, ensures healthy bones and teeth, and plays an important role for muscles, nerves, and the immune system.

The 25-OH vitamin D test is the best method to check vitamin D status. Low levels can indicate too little sunlight, an unbalanced diet, or diseases and are associated with bone diseases such as osteoporosis or rickets. Excessive levels usually result from too high supplement doses and can strain the kidneys and liver.

Albumin is the most common protein in blood plasma and is produced in the liver. It retains fluid in the vascular system and transports vitamins, enzymes, and hormones.

A deficiency may be caused by liver or kidney diseases, inflammation, or poor protein supply. High albumin levels occur with fluid loss or a very high-protein diet. Since albumin also reflects the nutritional situation, persistently low levels indicate insufficient protein intake and an increased risk of muscle weakness or infections.

Ferritin is a protein that stores iron in the body and releases it when needed. The ferritin level in the blood indicates how well the body's iron stores are filled and is therefore often used to assess iron status.

Low values usually indicate an iron deficiency or anemia. Elevated values may suggest inflammation, liver diseases, or iron overload.

Calcium is an essential mineral primarily stored in bones and teeth. It ensures the stability of the skeleton and plays an important role in muscle function, blood clotting, and nerve signal transmission. A blood test measures the proportion circulating in the blood.

Too low calcium levels can cause muscle cramps, tingling, or heart rhythm disturbances. Too high levels often indicate disorders of the parathyroid gland, certain tumors, or excessive intake of vitamin D.

Sodium is an important mineral and electrolyte that regulates the body's water and salt balance. It also plays a central role in nerve signal transmission and muscle function. The body usually maintains sodium levels within a narrow range to keep essential functions stable.

High levels (hypernatremia) often occur with fluid deficiency and can trigger thirst, confusion, or seizures. Low levels (hyponatremia) arise, for example, from significant fluid loss, kidney problems, or certain medications and lead to weakness, headaches, and in extreme cases, consciousness disorders.
