15 alimente bogate în vitamina A care stimulează producția de colagen și susțin sistemul imunitar
Retinol, a derivative of vitamin A, is widely recognized for its anti-aging properties and skin health benefits. It can be found in both skincare products and various foods. Vitamin A is crucial for skin, hair, and nail health, as well as immune function. It exists in two forms: preformed vitamin A from animal sources and provitamin A carotenoids from plants. Adequate intake supports skin renewal and immune health, while excessive consumption can lead to toxicity. Recommended daily allowances vary by age and sex, and a balanced diet is essential to meet these needs. Foods rich in vitamin A include liver, dairy, carrots, and leafy greens, among others. While topical retinol is effective for skin appearance, dietary vitamin A plays a broader role in overall health.
