Blackmores Bio Magnesium supplement: Effective in reducing muscle cramps and improving sleep quality. Easy to swallow and gentle on the stomach. Noticed a difference within a week. Packaging is convenient. Price is reasonable for the benefits. Overall, a solid choice for magnesium.

I have been using your Bio Magnesium and Joint Formula Advance tablets for a long time. Recently you changed your bio magnesium tablets from a smaller tablet to a large one which looks exactly the same as the joint formula tablets. When I have to take them out of their bottles for travelling it is very frustrating not to know which one is which. Please make them different!

Many adolescent girls, women and men may not get enough magnesium in their diets. Deficiency is most prevalent in men and women aged 45 plus. Bio Magnesium is a supplement to aid in the prevention of magnesium deficiency states. If the body is low in magnesium it is forced to take it from muscles and without enough magnesium in muscles they stiffen up or contract at liberty. The result may be painful cramps, irritability, twitching or even tremors. Sufficient magnesium helps all muscles in the body to function optimally. Medical studies have shown calcium and magnesium to have a favourable impact on bone integrity and Bio Magnesium contains both calcium and magnesium for this purpose. Magnesium is essential for the electrical activity of nerves and muscle, and is indicated to relieve painful cramps (including menstrual cramps), twitching and tremors. Together with calcium, magnesium plays an integral role in tooth and bone hardness. Other nutrients present in Bio Magnesium also assist muscle function and include vitamins C and D (low intake has been associated with muscle fatigue), vitamin B6 and the mineral manganese which is involved in active phosphate transfer processes to provide muscle energy.
