When it comes to staying healthy and feeling your best, what you eat plays a huge role. Your body needs a variety of nutrients to function properly, from keeping your energy up to supporting your immune system. But did you know that the food you eat can also have a big impact on your skin? Getting enough of the right vitamins and minerals can help keep your skin looking smooth, bright, and youthful — and may even slow down some signs of aging.
While there are many nutrients that support healthy skin, it doesn’t have to be overwhelming. To keep things simple, a naturopathic doctor recommends focusing on just three key vitamins that can make a real difference.
These vitamins not only help you feel good from the inside out, but they can also give your skin a natural, healthy glow. Here’s a look at the three vitamins that can help you look (and feel) your best.
1. Vitamin K2
Vitamin K2 might not be the first thing that comes to mind when you think about skincare, but it plays a surprisingly important role in keeping your skin looking youthful. One of its main benefits is that it helps direct calcium to the right places in your body—like your bones and teeth—and keeps it out of places where it doesn’t belong (like your arteries and soft tissues).
When calcium builds up in the wrong areas, it can lead to stiffness and a loss of elasticity, making the skin appear older and less firm. Vitamin K2 supports healthy calcium distribution, and this can help maintain skin elasticity and reduce the appearance of fine lines and wrinkles. This vitamin can be found in fermented foods like natto and certain cheeses, but a supplement may help if you don't feel you're getting enough of it in your regular diet (check in with your doctor first).

2. Magnesium
One of the key ways magnesium helps your skin stay youthful is by reducing inflammation and supporting healthy stress responses in the body. Chronic stress and inflammation can speed up skin aging, leading to breakouts, dullness, and early wrinkles. Magnesium also plays a role in balancing hormones and improving sleep—two major factors in how your skin looks and feels. When your body has enough magnesium, your skin barrier can function more effectively, locking in moisture and keeping out irritants.

3. Collagen
As we age, our natural collagen production starts to decline, which can lead to sagging, wrinkles, and a thinner complexion. That’s why supporting collagen levels is key if you want your skin to look youthful. You can boost collagen through collagen-rich foods like bone broth, or by taking collagen supplements, which have become super popular. Collagen also works best when your body has enough of the nutrients it needs to build and use it properly, like vitamin C, zinc, and amino acids. Supporting your collagen levels can improve skin elasticity, reduce the appearance of fine lines, and help maintain a healthy, hydrated glow from the inside out.
