Health Benefits of Vitamin K2
Vitamin K2, especially the MK-7 form, helps direct calcium to your bones and teeth while keeping it out of your arteries. That means stronger bones, a healthier heart, and even better dental health. Pair it with vitamin D for maximum effect – D brings calcium in, K2 puts it where it belongs. Regular intake can support bone density as you age and maintain cardiovascular flexibility. Studies show that K2 activates osteocalcin and matrix Gla protein, two key players in calcium metabolism. It's a simple addition to your daily routine that pays off long-term.
What Is Vitamin K2?
Vitamin K2, or menaquinone, is a fat-soluble vitamin that takes care of calcium direction in the body. Unlike vitamin K1 (phylloquinone), which mainly handles blood clotting, K2 is essential for bone and heart health. The most studied subtype, menaquinone-7 (MK-7), has superior bioavailability and a longer half-life, so it stays active in your system longer. That makes it the ideal choice for daily supplementation. You'll find K2 in fermented foods like natto and some animal products, but most diets don't provide enough – that's where a supplement comes in.
Vitamin K2 vs. K1: Key Differences
Both are vitamin K, but they play different roles. K1 comes from leafy greens and is quickly used by the liver for clotting. K2 from fermented foods and animal products lasts longer and activates proteins that regulate calcium. MK-7 specifically supports osteocalcin (for bone mineralisation) and matrix Gla protein (to stop arterial calcification). If you're after targeted bone and heart support, K2 – especially MK-7 – is the way to go. Think of K1 as the short-term worker and K2 as the long-term planner.
How to Choose a Vitamin K2 Supplement
When picking a K2 supplement, go for the MK-7 form – it's better absorbed and stays in your system longer. Look for vegetable-based softgels for easy digestion and check for Non-GM and gluten free certifications. Lake Avenue's Vitamin K2 is made in a cGMP-compliant facility and third-party tested for purity and potency. That means you get a quality product you can trust every serving. And because it's vegan-friendly, it suits almost any lifestyle.
Recommended Dosage
Each vegie softgel provides 50 mcg of vitamin K2 as MK-7. This dose matches general wellbeing guidelines for adults. For best absorption, take with a meal that contains some fat – K2 is fat-soluble, so it needs fat to be absorbed properly. Most adults can take one softgel daily. If you're on blood-thinning medication like warfarin, check with your doctor before starting, as vitamin K can interact with these drugs. Always read the label and follow directions for use.
Potential Side Effects & Interactions
Vitamin K2 is generally very well tolerated at recommended doses. No serious side effects have been reported from taking up to 100 mcg daily of MK-7. However, high doses may interfere with anticoagulant therapy, so always tell your doctor about any supplements you're taking. Pregnant or breastfeeding women should get professional advise before starting something new. When in doubt, ask your healthcare provider – it's better to be safe.
Frequently Asked Questions
Can I take Vitamin K2 with Vitamin D? Absolutely – they work together perfectly. Vitamin D helps your body absorb calcium, and K2 makes sure it goes to your bones and teeth, not your arteries.
Is there a difference between K2 and MK-7? MK-7 is a type of K2 with a long half-life, so it keeps your levels steady. Other forms like MK-4 don't last as long. MK-7 is the one you want for consistent support.
Do I need Vitamin K2 if I eat a healthy diet? Even a balanced diet can be low in K2. Natto is a great source, but it's not common in Aussie meals. Supplementation helps fill the gap.
Is this product vegan? Yes – the softgels are vegetable-based, so they're suitable for vegans and vegetarians.
