Vitamin K2, an essential nutrient, is often unnoticed in our regular diet. This vital vitamin contributes significantly to our bone, heart, and dental health. While leafy vegetables are rich in Vitamin K1, Vitamin K2 is primarily present in animal-based products and fermented foods. For people who seldom eat these types of foods, supplementing their diet with Vitamin K2 becomes crucial.
When it comes to choosing the best K2 supplement, there are a few critical factors to consider. First and foremost is the type of K2 being used. There are two main forms of K2: MK-4 and MK-7. MK-4 is a shorter-chain molecule and is found in animal products, while MK-7 is a longer-chain molecule and is found in fermented foods. MK-7 has been shown to have a longer half-life in the body and may be more beneficial for bone and heart health.
Another factor to consider is the dosage of K2 in each supplement. The optimal dosage of K2 is still up for debate, but most studies have used doses ranging from 45 mcg to 1,000 mcg per day. It’s important to note that K2 supplements are not regulated by the FDA, so it’s essential to choose a reputable brand and follow the recommended dosage on the label.
