Vitamin K2 is a critical yet often overlooked nutrient that supports bone mineralization and helps prevent calcium buildup in the arteries. When combined with vitamin D3, it ensures calcium is absorbed efficiently and directed to the right places in your bones and teeth, not your arteries.
Many adults, especially those over 50, don’t get enough K2 through diet alone, which increases the risk of osteoporosis and cardiovascular calcification.

Key Fact: Clinical studies show that regular vitamin K2 (MK-7) intake can reduce age-related bone loss by up to 25% in postmenopausal women.
