Holland & Barrett Calcium plus Vitamin D and K 60s

This nutitional supplement contains Calcium,Vitamins D and K.Calcium plays a very important role in the body to strengthen bones.It also contributes to normal muscle function.It is also necessary for maintaining healthy communication between the brain and other parts of the body. It plays a role in muscle movement and heart function.Alongside calcium comes? vitamin D which helps the body absorb calcium.?

Muscle contraction

Calcium helps regulate muscle contraction. When a nerve stimulates a muscle, the body releases calcium. The calcium helps the proteins in muscle carry out the work of contraction.When the body pumps the calcium out of the muscle, the muscle will relax.Calcium?s role in muscle function includes maintaining the action of the heart muscle. Calcium relaxes the smooth muscle that surrounds blood vessels. Various studies have indicated a possible link between high consumption of calcium and lower blood pressure.

Cardiovascular system

Calcium plays a key role in blood clotting. The process of clotting is complex and has a number of steps. These involve a range of chemicals, including calcium which is a major chemical in the clotting cascade.

Other roles

Calcium is a co-factor for many enzymes. Without calcium, some key enzymes cannot work efficiently.

Studies have also suggested that consuming enough calcium can result in:

• a lower risk of developing conditions involving high blood pressure during pregnancy
• lower blood pressure in young people
• lower blood pressure in those whose mothers who consumed enough calcium during pregnancy
• improved cholesterol values
• a lower risk of colorectal adenomas, a type of non-cancerous tumor.

Vitamin K plays an important role in blood clotting, bone metabolism, and regulating blood calcium levels.The body needs vitamin K to produce a protein and clotting factor that is important in blood clotting and bone metabolism. People who use blood-thinning medications, such as warfarin,rivaloxaban (xarelto, harteze) should not start consuming additional vitamin K without first asking a doctor.It has also shown to improve memory in ageing adults.Vitamin K may help keep blood pressure lower by preventing mineralization, where minerals build up in the arteries. This enables the heart to pump blood freely through the body.

?

Vitamin K can interact with several common medications, including blood-thinners, anticonvulsants, antibiotics, cholesterol-lowering drugs, and weight-loss drugs.

Blood thinners, such as warfarin and rivaloxaban (xarelto,harteze) are used to prevent harmful blood clots that may block blood flow to the brain or heart. They work by decreasing or delaying vitamin K?s clotting ability. Suddenly increasing or decreasing vitamin K intake can interfere with the effects of these drugs. Keeping vitamin K intake consistent from day to day can prevent these problems.

Anticonvulsants, if taken during pregnancy or while breastfeeding, can increase the risk of vitamin K deficiency in a fetus or a newborn. Examples of anticonvulsants are phenytoin,phenobarbitone.

Cholesterol-lowering medications interfere with fat absorption. Dietary fat is necessary for absorbing vitamin K, so people who are taking this medication may have a higher risk of deficiency.

Anyone who is taking any of these medications should speak to their doctor about their vitamin K intake
