Dr. Mercola Vitamin K2 180 mcg
Brand: Dr. Mercola · Form: CAPSULE [E0159]
Our assessment
The evidence shows that Dr. Mercola Vitamin K2 180 mcg is a single-ingredient supplement. Based on the data provided, we cannot assess the benefits of vitamin K2 specifically because no data on this ingredient is included. For the ingredient calcium, which is sometimes paired with vitamin K2, the data shows it supports bone density and nerve signaling [NIH ODS]. However, you should know that this product contains only vitamin K2, and data on that specific ingredient is not available in the provided materials.
How it works
If calcium were in this product, it would work through bone mineralization and neuromuscular relaxation [NIH ODS]. However, this product contains vitamin K2, and the mechanism of action for K2 is not detailed in the data provided. The available data is limited to calcium's role in supporting bone density and muscle relaxation [NIH ODS].
Safety profile
The FDA received a total of 592,059 adverse event reports for all dietary supplements combined [FDA data]. For the ingredient calcium specifically, high intakes might increase the risk of heart disease and prostate cancer, and can cause constipation, nausea, and abnormal heart rhythms [NIH ODS]. Side effect report counts for vitamin K2 are not available in the data provided. Calcium can also reduce absorption of several medications including bisphosphonates and levothyroxine [NIH ODS].
Our recommendation
Because no specific data on vitamin K2 was provided for this product, we cannot make a confident recommendation. Data not available for vitamin K2 benefits, side effects, or studies. If you are considering this supplement, consult your healthcare provider. For general bone health, calcium's benefits are well-documented, but high intakes carry risks [NIH ODS]. We recommend discussing your specific health needs with a qualified professional before starting any new supplement.
