Though experts maintain that the best way to ensure you’re getting enough vitamins and minerals in your diet is through the foods you eat, there is some evidence to support the benefits of taking certain vitamin supplements, as well. To learn more about the best hair, skin, and nails vitamins in particular, Elite Daily spoke with nutrition and exercise consultant Mary Jane Detroyer M.S., R.D.N., C.D.N., who explained that, “Our bodies' immune systems function optimally when we provide foods rich in minerals and vitamins, and our bodies absorb and use vitamins and minerals from food much more efficiently than supplements." But not everyone is eating the optimal range of foods to best support the health of their skin and organs, and there may be other reasons for vitamin deficiencies that can impact our hair, skin, and nails.
In premenopausal women, for example, iron deficiency is a common cause of hair loss, and “severe deficiencies in protein, vitamin D, and zinc are also associated with diffuse hair loss," Detroyer says. She also reports that there’s research that biotin can help promote stronger nails, and may help hair grow faster and stronger, though it does not result in an increase in hair follicles. Vitamins D and A are both essential for supporting the integrity of our skin, but other vitamins also play key roles in keeping us balanced.
The following supplements contain vitamins that promote stronger hair, skin, and nails. But note that before taking any new vitamin, you should always speak with your doctor first — especially if you're already taking other medications.
