Vitamins and antioxidants are micronutrients that the body needs in small amounts but are extremely important for the functioning of various systems throughout the body.

Taking vitamin supplements without knowing your blood vitamin levels can lead to these problems:

• **Toxicity (Overdose):** Certain fat-soluble vitamins, such as vitamins A, D, E, and K, can accumulate and become toxic to the body if taken in excessive amounts.
• **Interference with other mineral balances:** Taking high doses of some minerals for an extended period can interfere with the absorption of other essential minerals. For example, excessive intake of Zinc may lead to Copper deficiency.
• **Failure to address the root cause:** Chronic fatigue, hair loss, or dull skin may not always be due to Vitamin C deficiency, but could be caused by Iron deficiency, Vitamin B deficiency, or hormonal imbalance. Taking vitamins randomly therefore fails to solve the problem directly.

By checking blood vitamin levels, the physician can provide precise recommendations for modifying dietary habits, lifestyle, and consider supplemental vitamins with the correct type and dosage suitable for each individual.

Therefore, this testing leads to focused and effective health care, helping to prevent illness and promote a good quality of life in the long term.

Suitable for: Everyone, but the symptoms and groups that should consider testing include:

• Those with symptoms of chronic fatigue, easy tiredness, hair loss, dull complexion, frequent acne, frequent muscle cramps, insomnia, frequent forgetfulness, or frequent colds.
• Seniors, due to decreased nutrient absorption with age.
• Those with incomplete diets (not eating all 5 food groups), such as vegetarians or those restricting certain foods.
• Those with certain chronic diseases, such as disorders related to the digestive system and absorption, or kidney disease.
• Those taking certain medications regularly, which may affect vitamin absorption.
• Those who regularly consume alcohol or smoke.
• Those with high stress and insufficient rest.
• Those planning to conceive.
• Athletes or those with high energy expenditure. Mineral and vitamin balance helps enhance muscle function, recovery, and overall stamina.
• Those who regularly take supplements, to assess whether they are receiving an appropriate amount.

Preparation Before Testing

• No need to fast from food or water.
• Wear loose-fitting clothing for blood pressure measurement and blood drawing.
