Detailed answer

Stretch marks are not a direct sign of vitamin K deficiency. Stretch marks are caused by the stretching of the skin, often due to rapid weight gain or growth. Vitamin K deficiency primarily affects blood clotting and bone health, and is not directly linked to the development of stretch marks. However, adequate intake of essential vitamins and minerals, including vitamin K, is important for overall skin health and may indirectly contribute to minimizing the appearance of stretch marks.
