For these reasons, NAC supplements are often used as an effective way to support overall health and strengthen the body’s resistance to daily stressors.

Caution should be exercised when taking NAC supplements, particularly by individuals on long-term medication, pregnant or breastfeeding women, and those with chronic diseases or respiratory conditions requiring treatment. In such cases, consult a doctor before starting supplementation.
