The Benefits of Calcium


Calcium is one of the most abundant and vital minerals in the body. It is thought that nearly 99% of the body’s calcium is stored in the bones and teeth, whilst the remaining 1% circulates in the blood. When blood calcium levels are low, the body robs calcium from the bones which can cause bones to become porous and weak over time. Maintaining healthy calcium levels helps to strengthen bones and support muscle function. Calcium also plays a role in the production of digestive enzymes that can help to neutralise stomach acids and may reduce heartburn.


With Added Magnesium


Magnesium facilitates the absorption of calcium into the body by keeping it soluble. For this reason, calcium and magnesium supplements can be particularly effective at maintaining strong and healthy bones. Magnesium also works independently to support muscle contraction and the transmission of messages through the nervous system. Magnesium may help to maintain a healthy electrolyte balance, which plays a vital role in the body’s fluid balance and muscle function. Some people find that adding higher levels of magnesium to their diet can help to reduce muscle fatigue and cramps.


Popular Formula for Bone Health 


Alongside the natural ageing process, certain lifestyle factors can also deplete the body’s calcium and magnesium stores. People who exercise regularly or drink high amounts of caffeinated drinks may require more calcium and magnesium in their daily diet in order to maintain healthy electrolyte levels. For best results, magnesium and calcium should be taken in a 2-1 ratio. Our Calcium 400mg and Magnesium 200mg has been specifically designed for rapid and efficient absorption in the body. At Simply Supplements all our products are manufactured in the UK to EU standards that guarantee quality and potency.

    Q: I use steroid inhalers for asthma and have been advised by a chemist to take a calcium supplement - which one is the best to take please?
    A: Either of our calcium supplements would be beneficial as both Vitamin D3 and Magnesium help the body to absorb the calcium. Magnesium is also used to help with feelings of tiredness & fatigue and also to help support nervous system & muscle function, whereas out Vitamin D3 is used to help support your immune system, week bones and teeth. which of these you would prefer to take would be at your own discretion.

    i suffer from painful leg cramps during the night and in the mornings. i've heard that magnesium tablets can help to reduce cramps. is this true? 


    Cramps in the legs are extremely common, especially during periods of rest. Frequent cramps are often caused by low levels of magnesium, calcium and potassium in the body. Many people find that supplementation with magnesium can help to reduce these cramps, therefore we would certainly recommend this product to you.  

    Nocturnal leg cramps can also be caused by dehydration. Ensure that you drink plenty of water throughout the day to remain hydrated.

    Q: Is it better to take calcium with magnesium or with vit D, or should I buy the three separately or one combined with the other separate. I also take cod liver oil.

    As supplements are not prescription medicines, it is difficult to advise what will work better, as different products will work in different ways for each person. Both Calcium & Vitamin D3 and Calcium & Magnesium are very popular products. Cod Liver Oil naturally contains vitamins A and D, so you may find that you only need to take a Calcium & Magnesium tablet alongside your current Cod Liver Oil capsules.

    Q: I am taking Simply Supplements Slimmex. Will it be okay for me to take the Calcium
    and Magnesium supplement at the same time?

    Yes, providing that you do not exceed the recommended dosages for each product, it is perfectly safe to take this product alongside Slimmex. If you do have any concerns, we would advise that you consult your GP.

    Q: Are these tablets suitable to take in pregnancy and while breastfeeding?

    Calcium and magnesium are both important minerals for growing babies and children. However, it is always best to check with your GP or Midwife before taking any supplements when pregnant or breastfeeding.

    Leg cramps at night
    Kerry Mitchell , Maltby
    A few months back I started getting cramps in my legs, particularly at night. A friend told me that she had also suffered from night cramps and that taking a magnesium supplement had stopped them. I thought I'd give this product a go as I already purchase glucosamine and cod liver oil from you, and so far it has been very rewarding. My night cramps have all but gone (although they have occurred on the odd occasion during the day) and I now get a better nights sleep.
