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 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 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.
