How to identify nutrient deficiencies?

To identify nutrient deficiencies, the most reliable method is to conduct blood tests. These tests can verify if there are low levels of essential nutrients like vitamin D, magnesium, or iron. It's advisable to seek professional healthcare advice for accurate testing and diagnosis.

Additionally, several signs and symptoms can suggest nutrient deficiencies:

• Low energy levels and fatigue can indicate deficiencies in vitamins like B12 or iron.
• Poor hair, skin, and nail health might suggest lack of biotin, omega-3 fatty acids, or vitamins A and C.
• Frequent illness or slow-healing wounds can also point to deficiencies in zinc or vitamin C.

A balanced diet rich in diverse food groups is generally recommended to avoid these deficiencies. Some nutrient-dense foods include organ meats, seafood, fruits, and vegetables, which can help cover various micronutrient needs 1.
