Higher Nature Vitamin K2

Our assessment
The evidence shows that vitamin K2 is a critical cofactor for directing calcium to your bones and away from your arteries, where it could cause harm. However, the data provided does not include specific studies or adverse event reports for vitamin K2 itself, so our assessment is based on the role of calcium, which vitamin K2 helps regulate [NIH ODS].
How it works
Think of vitamin K2 as a traffic director for calcium in your body. It activates proteins that help move calcium from your bloodstream into your bones, where it supports bone density and mineralization. At the same time, it helps prevent calcium from depositing in your soft tissues, such as your arteries [NIH ODS]. This is why getting enough K2 is especially important if you take a calcium supplement.
Safety profile
Data not available for vitamin K2-specific adverse events. The FDA has received 592,059 total adverse event reports across all supplements, but no specific report count for K2 is provided. Because vitamin K2 works closely with calcium, it is important to note that high calcium intakes can cause constipation, nausea, weight loss, extreme tiredness, and abnormal heart rhythms [NIH ODS]. Calcium can also reduce the absorption of medications including bisphosphonates, tetracycline antibiotics, and levothyroxine [NIH ODS].
Our recommendation
Start by assessing your dietary intake of vitamin K from foods like natto, leafy greens, and cheese. If you are taking calcium supplements or have concerns about bone health, vitamin K2 may be a helpful addition, but you should discuss it with your healthcare provider first, especially if you take blood thinners or other medications. Data on optimal dosing is not available in the provided information.
