What is Vitamin K2?
Vitamin K2 is a relatively common fat-soluble vitamin. It plays a significant role in balancing the metabolism of calcium in the human body, protecting bone and cardiovascular health. At the same time, it can precisely regulate the distribution of calcium in the human body, ensuring that calcium ions in the blood are deposited in the collagen of bones, thereby increasing bone density and strength.
What is Vitamin D ？
Vitamin D is an essential fat-soluble vitamin for the human body. Its main function is to regulate the metabolism of calcium and phosphorus in the body, enhance the body’s immunity, promote cell growth, and play a very important role in maintaining the health of the bones and teeth. At the same time, it also has the functions of protecting muscle tissues and neurons, and inhibiting the growth of cancer cells.
Why should you take Vitamin k2 with Vitamin D ?
The main function of Vitamin D is to promote the absorption of calcium in the human body and enhance the efficiency of calcium absorption. It transports calcium into the bloodstream, but it cannot control the final destination of calcium ions.
Without the assistance of Vitamin K2, calcium in the blood will deposit in the walls of blood vessels, the heart, joints and other parts of the body, posing potential health risks.
Vitamin K2 can activate the bone sialoprotein in the human body, which can combine with calcium in the blood and “transport” them to the collagen in the bones, thereby promoting the increase of bone density and enhancing its strength.
In addition, Vitamin K2 can also activate MGP, removing the excessive calcium deposited in the vessel walls and reducing the risks of vascular hardening and arteriosclerosis.
When there is only Vitamin D in the blood but not enough Vitamin K2, a large amount of calcium will accumulate in the blood and at the joints improperly, reducing the efficiency of calcium supplementation and causing a series of health risks.
Conversely, the effect of Vitamin K2 will be greatly reduced. The human body will suffer from problems such as osteoporosis, slow bone development, muscle weakness, weakened immunity, and abnormal blood sugar due to calcium deficiency.
In conclusion, only by taking Vitamin D and Vitamin K2 together can the efficiency of calcium absorption be maximized, protecting bone and cardiovascular health, enhancing immunity, and maintaining overall physical well-being.
How to take Vitamin K2 along with Vitamin D?
The dosage of Vitamin K2 and Vitamin D varies depending on the population. The specific ratio of combination is: 1000 IU of Vitamin D3 : 100 μg of Vitamin K2 (MK-7). Following this ratio can maximize the absorption and utilization of calcium.
General dosage
The daily safe doses of Vitamin D and Vitamin K2 for adults are as follows:
• Vitamin D3: 800 – 1000 IU per day
• Vitamin K2 (MK-7): 80 – 100 μg per day
Dose for special populations
Middle-aged and elderly people
• Vitamin D3: 1500 – 2000 IU per day
• Vitamin K2 (MK-7): 150 – 200 μg per day
People with cardiovascular diseases
• Vitamin D3: 1000 – 1500 IU per day
• Vitamin K2 (MK-7): 150 – 200 μg per day
Teenagers in the growth period
• Vitamin D3: 800 – 1000 IU per day
• Vitamin K2 (MK-7): 50 – 80 μg per day Important Reminder
The daily intake of vitamin K2 and vitamin D should not exceed the safety limit; otherwise, it may pose health risks.
The specific safety limits are as follows:
Vitamin D3: 4000 IU
Vitamin K2 (MK-7): 300 μg
Summary and Recommendations
Vitamin K2 and Vitamin D must be taken together to achieve the effects of promoting calcium absorption, maintaining bone health, and enhancing immunity. Taking Vitamin D alone can bring a series of safety risks such as calcium precipitation in the blood. Moreover, the dosage of Vitamin K2 and Vitamin D varies for different populations and should be taken under the guidance of a professional doctor.
