Vitamin K Absorption
Question: If vitamin K absorption appears to be reduced by other fat-soluble vitamins, like vitamin D, why do some "bone health" supplements combine them? Should they be taken separately?
Answer: Vitamin K and vitamin D may each play a role in bone health, which is why they are often included together in bone health supplements. However, it may be best to take vitamin K apart from other fat-soluble vitamins, as explained in the What to Consider When Using section of the Vitamin K Supplements Review.
