Bonemax Calcium & Magnesium 250mg Capsules

(5 customer reviews)

Bonemax Calcium & Magnesium 250mg Capsules supplies calcium and magnesium along with organic cider vinegar to create that optimum acidity, allowing for far greater absorption than taking calcium and magnesium through other means.



Calcium & Magnesium – Essential Minerals for Muscle & Bone Health

Calcium and Magnesium are essential minerals that help maintain normal bones and muscle function. This powder provides an excellent source of both minerals for people of all ages. Both minerals also contribute to normal metabolism.

Calcium and magnesium work in harmony in the human body, at a ratio we have mirrored in this unique formula. We use custom spray-dried cider vinegar, which creates mineral acetates, thereby helping the body assimilate them faster. In addition, Bonemax Calcium & Magnesium 250mg Capsules also provide traces of potassium, phosphorous, zinc and iron.

Calcium, Magnesium and Muscle Cramps

If you suffer with muscle cramps in the leg, especially at night, it may be a sign that your calcium, magnesium or potassium levels are low. This is because both minerals help maintain muscle function, as well as helping to balance electrolyte levels. Hydration is vital as all electrical signalling activity in the muscles occurs in a water environment and so inadequate hydration levels within the body could lead to impaired electrical signalling and an increased occurrence of cramping.

It is also important to maintain levels of other minerals including sodium and potassium based on their involvement in conducting electrical signals to/from muscles; and of course calcium and magnesium, which are essential for the contraction and relaxation of muscle fibres.

Controlling muscle contraction & relaxation is dependent on levels of calcium and magnesium. Both work together to help maintain normal electrical signalling and to synchronise muscle contraction/relaxation responses in the muscles. In muscle cells, an increased in calcium causes muscle fibres to contract, whereas Magnesium counteracts this effect by causing the muscle fibres to relax.

Calcium, Magnesium and Bone Health

Magnesium is vital for the absorption and metabolism of calcium. A deficiency of either one of these minerals will affect the metabolism of each of them. One mineral cannot work optimally in the body without the other. Taking calcium supplements but having low levels of magnesium can lead to calcium deposits in the soft tissues, such as the joints, where it can promote arthritis, or in the kidney, contributing to kidney stones.

Magnesium gives bones & teeth their strength. It is necessary for the conversion of vitamin D into its active form. Vitamin D also aids in the absorption of Calcium, demonstrating how Magnesium and Calcium go hand in hand. Magnesium deficiency has also been linked to Osteoporosis.

Magnesium is mainly stored in the bones. Bones release magnesium into the bloodstream when it is necessary. Therefore it is important to maintain magnesium levels in the body in order to help maintain these stores. Low levels of Magnesium, low blood & bone magnesium levels have been associated with Osteoporosis in women.

Suggested Uses:

  • Athletes after exercise
  • Half an hour before bed
  • Convalescents, twice or more daily
  • During pregnancy, daily
  • As needed to aid relaxation

Features & Benefits – Why Take Bonemax Calcium & Magnesium

  • Helps support normal muscle function
  • Helps support normal metabolism of calcium & magnesium
  • Helps maintain strong bones and teeth
  • Supports normal neurotransmission
  • Supports the normal functioning of the nervous system
  • Helps maintain electrolyte balance

Is Bonemax Calcium & Magnesium Right For Me?

Magnesium deficiencies are quite common especially in women and the elderly. Magnesium can be consumed through the diet via foods such as green leafy vegetables, whole grains, nuts, fish, dairy and meat, their magnesium content all depends on the magnesium levels in the soil. If the soil is magnesium deficient, so too will be the produce. This is why a supplement may be beneficial to your health. Low magnesium intake, as well as low blood and bone magnesium levels, has also been widely associated with osteoporosis in women.

Magnesium is necessary for calcium to work optimally within the body, therefore it is recommended the two minerals be taken simultaneously. Bonemax Calcium & Magnesium may be the ideal supplement for you to help support muscle function and bone health.

Calcium & Magnesium in the Press

Health Article: Daily Mail: Muscle cramps? Bad breath? Fatigue? They can all be caused by a lack of vitamins or minerals – so here’s how to eat yourself healthy

Most of us suffer from one of these annoying, minor health niggles at some point, little realising that a lack of vitamins or minerals may be to blame.

‘Diet and poor nutrition are often overlooked by health practitioners despite being related to everyday health complaints,’ says Professor David Kennedy, psychobiologist at Northumbria University.

When it comes to minor ailments there are lots of things you can do to help yourself.

As Ursula Arens explains: ‘You are the expert in what is normal for you, so if you’re suffering from a minor health complaint, try dietary changes or, where appropriate, supplements.’

The point about vitamins and minerals, she says, is that these are better absorbed from food than from pills – although in some cases the amount of food you’d need to eat is absurd, so a supplement may be worth considering.

For Muscle Cramps you need: Magnesium

This mineral is crucial for nerves transmitting messages to the muscles. But many of us are deficient, says Ursula Arens.

‘Our diets tend not to be very magnesium-rich because foods such as fast food, fizzy drinks, crisps, biscuits and refined grains are very low in magnesium.’ In addition, many of us consume a lot of milk and dairy products and these and other calcium-rich foods can lower magnesium levels’.

The Science behind Bonemax Calcium & Magnesium

In 1975, Behar published his study ‘Effect of calcium on magnesium absorption’ in the American Journal of Physiology. His study demonstrated that an increase in calcium levels within the body led to a decrease in magnesium. The decrease in Magnesium also saw a decrease in sodium.

This calcium effect was also observed when sodium chloride was replaced by urea. However, a consistent correlation was observed between the amount of net magnesium absorption and the rates of net water absorption of all calcium concentrations.

Behar’s findings suggest calcium decreases magnesium absorption by a nonspecific reduction in membrane permeability to solutes (the minor component in a solution) that induce net water flow and are consistent with the concept that magnesium is transported by solvent “drag”.

The increase in the concentration of calcium resulted in an increase in tissue accumulation of magnesium. This increase in tissue accumulation of magnesium was associated with a decrease in net sodium absorption.

These findings suggest an additional mechanism of magnesium transport operating independently of net water flow.

Published in ‘Nutrients’ 2013, Castiglioni et al conducted a study titled ‘Magnesium and Osteoporosis: Current State of Knowledge and Future Research Directions’

The study discussed how magnesium homeostasis seems to be crucial for bone health. Researching previous studies Castiglioni found that both low and high magnesium levels in the body have harmful effects on the bones. Researchers conclude low levels of magnesium contributes towards osteoporosis directly (by acting on crystal formation and on bone cells) and indirectly (by impacting on function of the ‘parathyroid’ hormone and by promoting low grade inflammation).

They concluded that controlling and maintaining magnesium homeostasis is one way to help maintain bone integrity.
