The Beauty Bar: Vitamin K's Best-Kept Secret
Well-known for its blood clotting and bone health benefits, new research shows vitamin K also plays a role in maintaining the skin’s elasticity.
What to take: Federal dietary guidelines recommend a minimum of 120 mcg a day for men and 90 mcg for women. A USDA survey found that nearly half of Americans fall short, even though dark leafy greens like broccoli, kale, and spinach provide more than five times the recommended minimum. Researchers are still investigating how much a healthy individual needs to reap K’s skin benefits, so in the meantime load up on extra greens when you can.
Keep in mind: If you’re on anticlotting medication, talk to a health professional before increasing your vitamin K.
