I have found that this product, Blackmore's Bio Magnesium, has been a great help in reducing the pain I get from leg cramps, especially at night. The 100 tablet bottle is a real bargain price in comparison with the smaller sized bottles.

Bio Magnesium, particularly the Blackmores brand assists the body with sleep & muscle relaxation. Highly recommend.

Before I used this product I got quite severe cramps several nights a week. After using this product for six months I no longer got cramps so I halved my daily dosage which keeps the cramps from returning.
Because of celiacs my body doesn't absorb enough nutrients even if I eat super healthily, and one of those nutrients that aren't absorbed properly is magnesium. Without bio magnesium I get cramps and muscle spasms throughout my body. Particularly annoying is the eye lid twitches, which last time they were really bad gave me a bruised, purple eye lid and all my friends thought I'd been in a fight or something. The bio mag keeps all of that at bay, I intend on taking it every day for the rest of my life. And it's wonderful to be able to buy it cheaply here with my other products.
Good product as I’ve been healing from a ankle fracture after 3 days of using this product I felt the difference in my body
Took it for a few years now for muscle cramps. At one stage ... I did stop taking this tablet thinking it's just a waste but the cramps got worst. Now, I am religiously taking this tablet - everyday.
Magnesium is an amazing product. Helps with Restless legs and cramps a lot.
I found both my husband and I had quite a few symptoms of magnesium deficiency so we started taking this year's ago and find it the easiest pill to swallow and a good dose to take and use it every day. No more muscle twitches ,better sleep and much more relaxed.
Relaxing and aids night cramps. Highly recommend.

Blackmores - Bio Magnesium 100 Tablets
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.
