Synergistically, they support healthy calcium metabolism and bone mineralization throughout the body as well as a healthy calcium balance in vascular tissues.† Vitamin D is also associated with cardiovascular disease risk factors†. Recent studies have shown that vitamins D and K support healthy functioning of both innate and adaptive immune response. † PuraWell's DK Fuel 5000 is a bioavailable combination of 5,000 IU of Vitamin D3 (cholecalciferol) and 100 mcg Vitamin K2 (menaquinone-7, MK7).

In the winter I feel so sluggish and sometimes depressed. I didn't realize it was as simple as not getting enough sun. During the winter months I take these every day. When I first started, I noticed a difference within a week. I felt much more energetic and motivated. I was out in the cold garage working on my cars again instead of sitting around the house watching TV. Caffeine will only make you crash and feel more tired. If your body needs Vitamin D, you won't feel better until it has some.
