Vitacost Vitamin K Complex 400 mcg
Brand: Vitacost · Form: SOFTGEL CAPSULE [E0161] On Market
Our assessment
The evidence shows that vitamin K is an important nutrient for bone and cardiovascular health, but data for this specific product is limited. You should know that the National Institutes of Health recognizes vitamin K's role in activating proteins that help bind calcium to bone and prevent calcium buildup in arteries [NIH ODS]. However, for this exact Vitacost formulation, specific clinical study data is not available.
How it works
Think of vitamin K as a traffic director for calcium in your body. It helps direct calcium to your bones where it is needed, and away from your arteries where it could cause harm [NIH ODS]. The 400 mcg dose in this product is well above the Adequate Intake of 120 mcg for men and 90 mcg for women, so you are getting a substantial amount of this fat-soluble vitamin [NIH ODS].
Safety profile
Data not available for specific adverse event reports for this product. In general, vitamin K has a low toxicity profile, and no tolerable upper intake level has been established by the NIH [NIH ODS]. However, you should be cautious if you take blood-thinning medications like warfarin, as vitamin K can interfere with their effectiveness.
Our recommendation
If you are looking to support bone health or cardiovascular function, this supplement provides a reasonable dose of vitamin K. However, because specific clinical studies on this exact product are not available, you should prioritize getting vitamin K from food sources like leafy greens, broccoli, and Brussels sprouts [NIH ODS]. Always consult your doctor before starting any new supplement, especially if you take prescription medications.
