With the fast-paced lifestyle, daily pressures, and lack of dietary variety, the body often needs additional support to maintain its balance and health. This is where dietary supplements come in, aiming to enhance a healthy diet without replacing it.

Conditions such as persistent fatigue, poor concentration, hair loss, or decreased immunity are among the most prominent signs indicating a nutritional deficiency that needs to be properly compensated. Therefore, in this article, we answer the question: When do I need a dietary supplement?

When do I need a dietary supplement?

There are several signs that may indicate a deficiency of certain vitamins and minerals in the body, including:

  1. Weak Hair and Nails

If you notice hair loss or brittle, easily broken nails, the cause may be a biotin deficiency. In cases of deficiency, taking supplements may be necessary, but a doctor should be consulted before use to ensure safety.

Biotin is found in whole grains, eggs, dairy products, nuts, salmon, and chicken.

  1. Constant Fatigue

Calcium can affect bone and tooth health and lower energy levels, causing a feeling of constant fatigue.

Calcium can be obtained from dairy products, dark green vegetables, almonds, legumes, or appropriate dietary supplements.

Leg cramps may indicate a deficiency in vitamin E, which is an important vitamin for maintaining body health and combating the effects of premature aging.

Vitamin E is available in nuts, seeds, vegetable oils, and leafy greens.

Pregnant and breastfeeding women need additional supplements such as iron and folic acid to ensure the mother's health and fetal growth.
