Common signs of vitamin deficiency include:

Fatigue, weakness

Persistent fatigue and a general feeling of weakness are common symptoms of essential vitamin deficiencies, especially vitamin D and B12. Vitamin D is important for bone health and muscle function, and a deficiency can lead to muscle weakness and unexplained feelings of fatigue.

Similarly, vitamin B12 is essential for red blood cell formation and nerve function. Deficiency of this vitamin causes anemia, which leads to fatigue and weakness.

Mood swings

Vitamin deficiencies can also have serious effects on mental health, causing mood changes and cognitive impairment. For example, some studies have linked vitamin B6 deficiency to depression, irritability, and thinking disorders.

This is because vitamin B6 is important for the synthesis of neurotransmitters. Therefore, a deficiency of this vitamin will disrupt the normal function of the brain.

susceptible to infection

A weakened immune system is a sign of vitamin deficiency, especially vitamin C and D. As a result, the body is often susceptible to infections and minor illnesses.

Vitamin C is well known for its ability to boost immunity, produce and support the activity of white blood cells. Meanwhile, vitamin D also plays an important role in regulating immune response.

Hair loss, skin problems

Hair loss and skin problems, such as dryness, flaking or acne, are also common signs of vitamin deficiency, especially vitamins A and B7.

Vitamin A plays an essential role in maintaining and regenerating the skin. A deficiency in vitamin A can cause dry skin and other skin problems. Meanwhile, vitamin B7, also known as biotin, is important in the production of keratin, a protein that makes up hair, skin, and nails. A deficiency in vitamin B7 can lead to thinning hair, dry skin, and brittle nails, according to Verywell Health .
