  • Heart & arterial health — Numerous studies show that vitamin K supports heart and arterial health, with higher vitamin K2 intake being correlated with a healthy cardiovascular system.
  • Helps maintain calcium balance — Vitamin K helps you incorporate calcium into your bones. As a part of maintaining “calcium balance”, this process helps keep calcium out of your arteries.
  • Vitamin K1 + two forms of K2 — It’s hard to get enough vitamin K from your diet. Super K provides vitamin K1 and two forms of bioavailable K2 to help you get enough daily vitamin K!

Vitamin K is an “essential” vitamin—your body cannot make vitamin K on its own. And we need it: vitamin K helps with everything from arterial health to bone structure.

But it’s hard to get sufficient vitamin K from food. Super K provides 100 mcg of vitamin K2 (MK-7); 1,000 mcg of vitamin K2 (MK-4); and 1,500 mcg of vitamin K1.

This once-daily softgel is a great way to ensure you get your daily dose of healthy vitamin K. Gluten-free, non-GMO, manufactured in the USA.

Great Quality and Stylish
Size: Large, Color: (001) Black / Black / White
Exactly what I was looking for. I don’t like socks that are no-show that your ankles rub on the shoe. These are taller than that but shorter than socks that go up and over the ankle. They’re comfortable, good quality, and pretty thick. They’re form fitting m, but not compression. I dint like compression socks, and these are tight, but not too tight.

Great for walking all day at work as well
Size: X-Large, Color: (001) Black / Black / White
I walk approximately 10 miles a day at work, in a manufacturing setting. On concrete with steel toe shoes. My feet have been begging me to change from the socks that I have worn for years. I have worn these other name brand socks for probably 10 years. So, change was obviously something I had to be pushed into. I got on Amazon and searched for training socks. I read the description. Glanced at the reviews. I decided to move forward with purchasing these. I could not have been happier. My feet began feeling better immediately. And the priced was very reasonible.
