Calcium, is an essential mineral in the human body. 99% calcium is stored in the bones and teeth to support their structure and hardness. Only one percent of calcium is found in the blood stream. The daily requirement of calcium varies according to gender and age. In general, women need more calcium than men especially during child-bearing age and before moving into the menopause phase.

If the body is not getting enough calcium, not only the bones and teeth are affected but other important body functions as well. Calcium will be drawn from the bones to support these body functions, leading to loss in bone mass. Apart from inadequate calcium supply in the body, declining level of oestrogen also cause low bone mass.  Oestrogen is one of the two main female hormones that controls not only the menstrual cycle, which is important for childbearing, but also other functions in the body as well.


Oestrogen helps in:

  • Bringing about the body’s physical changes that turn a girl to woman

  • Keeping the cholesterol in check

  • Providing protection on the bones

  • Helping to keep the blood vessels flexible

  • Keeping the heart healthy

When women are approaching menopause, their oestrogen levels start to decline gradually and this causes the protection on their bones and heart to go off-balance. Human body cannot make calcium and can only be obtained from diet and supplements. Most women religiously take their calcium supplement rather than drinking 4 glasses of milk a day to fulfil their calcium requirement in preventing osteoporosis. It is recommended to consume sufficient calcium since young. Most calcium supplements are added with vitamin D. One of the main functions of vitamin D is to maintain sufficient level of calcium in the blood by enhancing calcium absorption. For young girls, taking calcium supplements with vitamin D help to build healthy reservoirs of calcium in their bones. However, conventional calcium + vitamin D supplements are not recommended for women approaching the age of 40. They need calcium supplements that are fortified with vitamin K2. It is because without vitamin K2, such supplements may cause accumulation of calcium in the blood and when it combines with cholesterol, it can be dangerous to the heart, especially in peri-menopausal and menopausal women.

When excess calcium accumulates in the blood, it forms plaque which adheres to the walls of arteries. These deposits can cause partial or complete blockage. It also hardens the walls of the artery. Calcium deposits in the arteries can only jeopardize the normal blood flow if it partially or completely blocks the concerned artery. Visible symptoms depend on which artery of the body is blocked.


If the coronary artery is blocked, the symptoms are pain in the chest with slightest exertion, shortness of breath, heaviness in the chest and a slow or rapid heartbeat.


In case of calcium blockage in the artery supplying blood to the brain the symptoms are dizziness, slurred speech, memory loss, weakness in hands and legs, sudden and severe headache and difficulty maintaining balance.

Calcium deposits in peripheral arteries of the legs and arms or pelvis may produce symptoms such as numbness in the legs, tingling sensation in the affected area and pain and spasm of the muscles.


In medical terminology, such deposits of calcium and fatty material in the arteries is called atherosclerosis. Build-up of calcium deposits in the arteries increases the risk of coronary artery disease. People with elevated levels of calcium in their blood are much more susceptible to heart attacks and stroke.


To promote bone health, vitamin K2 allows calcium to be used by our bone-building cells to increase bone density. Increased bone density means stronger bones that are less likely to fracture or break. In a similar pathway, this vitamin redirects calcium from soft tissues and arteries to your bones. This increases your bone density and can potentially reduce stiffness in the arteries. Simply put, vitamin K2 can increase your bone size and might reduce cardiovascular risk!


A calcium supplement that is added with vitamin K2 can help strengthening the bones while keeping the heart healthy.  Women above 40 need to have vitamin K2 added into their calcium supplements to achieve a delicate balance between their bones and heart health.


Osteocalcin functions to lock and concentrates calcium in the bones. Vitamin K2 activates osteocalcin in order to allow the bone building cells to increase bone density. Increased bone density means stronger bones that are not likely to break or fracture. Multiple studies have examined on the benefit of vitamin K2 on bone health. One study confirmed that taking calcium supplements fortified with vitamin K2 reduced spinal fractures by 60%, hip fractures by 77% and all non-spinal fractures by 81%.


MGP (matrix GLA protein) is responsible in redirecting the absorbed calcium away from the soft tissues and blood vessels to the bones. Vitamin K2 activates MGP, hence it inhibits calcium deposition on the walls of the blood vessels, reducing damages caused by calcium plaque. This could also means lowering of calcium-associated health risks such as strokes and heart attacks.

In a study spanning up to 10 years, vitamin K2 was found to reduce the risk of calcium deposits in the blood vessels by 52%, thus reducing the risk of death due to heart diseases by 57%. In a separate study on 16,000 women, taking high level of vitamin K2 has shown to reduce the risk of heart disease significantly. Every 10 mcg of vitamin K2 consumed reduces the risk of heart disease by 9%.


Putting it in a simple perspective, while vitamin D acts like a gatekeeper, enhancing the absorption of calcium in the gut; vitamin K2, on the other hand, acts like a traffic police guiding calcium to the bones, where it is needed the most, while keeping the heart healthy.

Kordel’s Calcium + Vitamin D3 plus Vitamin K2 is formulated with Vitamin K2 from MenaquinGold™ ES that is stable. If you are a woman above 40, switch to this heartier heart calcium supplement for better utilisation of calcium in the body to have strong bones and a healthy heart.

Despite its valuable potential in bone and heart health, the stability of vitamin K2 is a problem when formulated with minerals such as calcium and magnesium. When formulated with these minerals, Vitamin K2 cannot survive in the harsh and alkaline environment. This leads to a significant depletion of vitamin K2 in such supplement. MenaquinGold™ ES Vitamin K2 provides the perfect solution to this stability problem. This special form of Vitamin K2 is highly stable because every granule of vitamin K2 is coated to protect it from rapid degradation.  This provides a longer stability and better efficacy of the product.


Don’t waste your money on buying a calcium supplement that is not formulated with a coated vitamin K2, when you are concerned about your heart health. Not all vitamin K2 are created equal. Choose the right one for the best protection.
