Introduction
Vitamin K2, existing primarily as MK7 (menaquinone-7) and MK4 (menaquinone-4), plays crucial roles in cardiovascular health. Both forms contribute to heart health by preventing arterial calcification and supporting cardiovascular function.
Understanding the difference between these two beneficial compounds, Vitamin K2 MK7 VS MK4, can aid in choosing the most effective supplement for heart health.
Understanding Heart Health
Heart health encompasses the well-being of the heart and the entire cardiovascular system, involving optimal blood pressure, cholesterol levels, and arterial function. Diet, exercise, genetics, and lifestyle choices significantly impact heart health. Poor heart health can lead to conditions like atherosclerosis, hypertension, heart attacks, and strokes. Nutrition, including essential vitamins like K2, supports cardiovascular function and prevents heart disease.
Vitamin K Types You Should Know
Vitamin K exists in two primary forms: Vitamin K1 (phylloquinone) and Vitamin K2 (menaquinone).
Vitamin K1 is found in green leafy vegetables and is essential for blood clotting.
Vitamin K2, further divided into subtypes like MK-4 and MK-7, is found in animal products and fermented foods, playing a significant role in bone and heart health.
Vitamin K2 MK7: The Most Bioavailable Form of K2 Vitamin
Vitamin K2 MK7 (CAS number: 2124-57-4) has the molecular formula C46H64O2 and a molecular weight of 649.00 g/mol. It is fat-soluble and typically appears as a yellowish oil or powder. MK7 is primarily found in fermented foods such as natto, a Japanese soybean dish, and certain cheeses. It boasts high purity levels, often exceeding 98%.
Health Benefits of Vitamin K2 MK7
VK2 MK7 is primarily used to support bone health, promote cardiovascular health, and reduce arterial calcification. The health benefits of MK7 include reducing arterial calcification and improving vascular health. MK7 activates proteins like osteocalcin and matrix Gla-protein (MGP), which help direct calcium to bones and prevent its deposition in arteries.
This dual action supports both bone and heart health. The typical dosage ranges from 45 to 200 micrograms per day. Side effects are rare but can include gastrointestinal discomfort.
How To Produce It?
MK7 is produced through fermentation using specific bacterial strains. The process involves culturing the bacteria, isolating the vitamin, and purifying it to achieve high potency.
How Does It Work?
The mechanism of action for MK7 involves activating proteins such as osteocalcin and MGP, which play crucial roles in directing calcium to the bones and preventing its deposition in the arteries. This mechanism supports bone and cardiovascular health by ensuring calcium is utilized correctly.
What Is Vitamin K2 MK4?
Vitamin K2 MK4 (CAS number: 863-61-6) has the molecular formula C31H40O2 and a molecular weight of 444.65 g/mol. Like MK7, it is fat-soluble and usually appears as a yellow oil or powder. MK4 is found in animal products such as meat, eggs, and dairy. It also has high purity levels, often exceeding 98%.
Health Benefits of Vitamin K2 MK4
MK4 primarily supports bone health, promotes cardiovascular health, and enhances brain function. The health benefits of MK4 include reducing arterial calcification and enhancing cardiac function. MK4 functions similarly to MK7 by activating proteins that regulate calcium utilization, thus supporting bone and heart health.
The typical dosage ranges from 1 to 45 milligrams per day. Although minimal, side effects may still include gastrointestinal issues.
How Does Vitamin K2 MK-4 Manufacture?
MK4 is usually synthesized chemically, which involves several steps to ensure purity and potency. This process is well-controlled to produce high-quality supplements.
How Does It Work?
The mechanism of action for MK4 involves activating proteins that regulate calcium utilization, similar to K2 Vitamin MK7. This ensures calcium is directed to the bones and prevents deposition in the arteries, supporting bone and cardiovascular health.
Comprehensive Comparison: Vitamin K2 MK7 VS MK4
Vitamin K2 MK-7 and MK-4, while beneficial for heart health, have distinct differences in their bioavailability, mechanisms of action, and overall effects. MK-7, with a longer half-life of up to 72 hours, provides sustained activation of matrix Gla-protein (MGP) and osteocalcin, which are crucial for preventing arterial calcification and promoting calcium deposition in bones.
This extended presence in the body allows for continuous regulation of calcium, making it particularly effective for long-term cardiovascular health.
In contrast, MK-4 has a shorter half-life of about 1 to 2 hours, leading to rapid absorption and utilization. This makes MK-4 more suitable for immediate calcium management needs, offering quick cardiovascular benefits but requiring more frequent dosing to maintain its effects.
The bioavailability of MK-7 is generally higher due to its prolonged activity, ensuring more consistent levels in the bloodstream. MK-4, though rapidly absorbed, may not sustain adequate levels without regular supplementation. Mechanistically, both forms activate MGP and osteocalcin, but MK-7’s longer half-life allows for prolonged activation and continuous prevention of arterial calcification.
Thus, while both forms support heart health, MK-7 is more effective for sustained cardiovascular protection, whereas MK-4 provides quicker, albeit shorter-lasting, benefits.
Vitamin K2 MK7 And MK4 Together: Yes or No?
Both Vitamin K2 MK7 and MK4 can be combined, offering complementary benefits. MK7’s prolonged action and MK4’s potent, shorter-term effects can provide a comprehensive approach to managing heart health. This synergistic effect ensures continuous support for cardiovascular function and arterial health.
What Are Vitamin K2 MK7 And MK4 Used For?
Vitamin K2 MK7 and MK4 have diverse application fields, predominantly supporting bone and cardiovascular health.
Vitamin K2 MK7, with its longer half-life, is especially beneficial for sustained cardiovascular support and preventing arterial calcification, making it a preferred choice in heart health supplements.
Vitamin K2 MK-4, on the other hand, offers quicker benefits and is noted for its positive effects on cognitive function, providing neuroprotective benefits that make it valuable in brain health supplements.
Safe Or Not?
Both K2 vitamin forms are considered safe within recommended dosages, with minimal side effects reported. They undergo stringent quality assurance processes, including third-party testing, to ensure purity and potency.
Conclusion
Vitamin K2 MK7 And MK4: How About Their Market Trend?
The growing awareness of their health benefits has significantly boosted market prospects, with increasing demand for both MK7 and MK4 supplements. The manufacturing processes – bacterial fermentation for MK7 and chemical synthesis for MK4 – ensure a steady supply of high-quality products, positioning them firmly in the global nutraceutical market.
Vitamin K2 MK7 and MK4 offer significant benefits for heart health by preventing arterial calcification and supporting overall cardiovascular function. While MK7 provides prolonged benefits due to its longer half-life, MK4 offers immediate effects at higher doses. Both forms can be used together for a comprehensive approach to heart health.
