When it comes to healthy aging, skincare products can only do so much. Many beauty experts say supporting your skin from the inside out is just as important, especially after age 40, when collagen production naturally begins to decline.
While there’s no magic pill that can stop the aging process, esthetician Chris Gibson says one supplement combination stands out for helping support healthy bones and collagen: vitamin K2 paired with vitamin D3.
Here’s why he recommends it.

Why Vitamin K2 + D3 Works Together
According to Gibson, vitamin K2 and vitamin D3 complement one another, making them more effective when taken together than on their own.
"The one supplement that I talk about for both men and women that's very important in helping to preserve the structure of your bones and your collagen is vitamin K2 plus D3," he explains.
Vitamin D3 helps your body absorb calcium, while vitamin K2 helps direct that calcium to where it's needed most—primarily your bones—instead of allowing it to build up in places where it doesn't belong.
It May Support Healthy Collagen
Although collagen supplements have become increasingly popular, Gibson says supporting your body's overall bone health can also benefit the structural foundation that helps skin maintain its firmness.
He notes that vitamin D3 works alongside K2 to help move calcium more efficiently throughout the body.
"It helps to make sure you're getting enough vitamin D, plus the vitamin D3 helps the K2 move calcium around in a more efficient way in the body," he says.
According to Gibson, this process helps keep calcium out of areas like the arteries and brain tissue while making it available for strong bones and healthy collagen levels.
Beauty Starts From Within
After age 40, collagen production naturally slows, contributing to fine lines, wrinkles, and loss of skin elasticity. While supplements alone won't erase signs of aging, experts say a balanced diet, regular exercise, sun protection, and adequate sleep all play important roles in maintaining healthy skin.
If you're considering adding vitamin K2 and D3 to your routine, it's a good idea to speak with your healthcare provider first—especially if you take blood-thinning medications or have underlying medical conditions, as vitamin K can interact with certain prescriptions.

The Bottom Line
Gibson believes vitamin K2 paired with vitamin D3 is one of the most beneficial supplement combinations for supporting healthy aging from the inside out. By helping your body utilize calcium efficiently, the duo may contribute to stronger bones and support the collagen that helps keep skin looking firm and healthy as you age.
