The Vitamin D+K2 Story

We formulated Vitamin D+K2 because these nutrients are critical to many aspects of optimal health but are routinely under-consumed or produced in inadequate amounts by our bodies.

An estimated 1 billion people worldwide, across all ethnicities and age groups, have a vitamin D deficiency due to poor dietary intake and other environmental factors.

To support optimal bone health, immune function, cardiovascular health, glucose tolerance, healthy hormones, strength, or mood, you may want to include Vitamin D+K2 in your daily supplement routine.*

Formula Highlights

  • Each capsule delivers 125mg (5000 IU) of cholecalciferol (Vit. D3) and 200mcg of Vitamin K2 as menaquinone-7.
  • Lactose-free formula (lactose is a common material used to dilute Vitamin D but can decrease absorption in those with lactose intolerance).*
  • Finished goods tested to confirm purity, potency, and absence of microbes or contaminants.*

Vitamin D3 (as Cholecalciferol) 

Maintaining optimal Vitamin D status is critical for overall health, and proper bone formation, immune function, and cardiovascular health. However, a large portion of North Americans may be deficient in Vitamin D. 

Vitamin K-2 (as Menaquinone) 

K-2 is found in animal foods and fermented foods, as two main sub- types: menaquinone (MK)-4 and MK-7. Wide variety of functions in the body, including benefits to bone and heart health and protection against blood vessel damage. Adequate Vitamin D is necessary for calcium absorption, but adequate vitamin K is needed to help direct the calcium to be incorporated into bone tissue and minimize calcium deposits in soft tissues such as our blood vessels and kidneys. Hence they work synergistically and can be taken together.

Frequently Asked Questions

How much Vitamin D should I supplement with?

Evidence suggests the current RDA for vitamin D is not high enough to support optimal vitamin D levels in many individuals. One capsule per day (5000 IU of vitamin D) is likely safe for most people but Life Time Fitness encourages you to have your vitamin D levels check with blood tests regularly (at least annually) to confirm the right dose for you individually.

Is there a risk of consuming too much Vitamin D with your supplement?

There may be some risk, which is why Life Time Fitness encourages you to have your vitamin D levels check with blood tests regularly (at least annually) to confirm the right dose for you individually. Some experts suggest not exceeding 10,000 IU per day without testing levels.

If I am taking your supplement, do I still need sun exposure? What about food sources of Vitamin D?

Yes, we still recommend direct sun exposure for 15-20 minutes daily to optimize Vitamin D levels in your body while still avoiding sun burn or excessive exposure. Foods high in Vitamin D are generally nutrient dense with other nutrients, such as seafood, organ meats, and mushrooms. Many other foods are fortified with Vitamin D, but not at sufficient levels to meet the higher vitamin D intakes recommended.

Does Vitamin D need to be processed in our bodies to be active?

Yes, the Vitamin D we synthesize internally from sun exposure must be converted (hydroxylated) to be biologically active to cholecalciferol (Vit. D3). This supplement contains the active, hydroxylated form.

Are there any interactions with Vitamin K?

Yes, vitamin K impacts blood clotting, so if you are taking any prescription drugs such as blood thinners Warfarin or Coumadin, consult with your medical doctor before supplementing with vitamin K.
