This supplement's ingredient is good quality. I do not use it for my joints. I use it to make me feel relaxed. I don't use it every day but from time to time, and it helps me sleep better. Mg is an excellent mineral but should not be used excessively. There is no taste to this product. I feel my muscles more relaxed when I take it.Improvement was noticeable. The package arrived on time and the product quality was optimum. I have benefited from this product and will buy it again.

I think this product is almost identical to "Magnesium 250mg" also from 21st Century (although the 250mg version contain 110 tablets per bottle). Pics are side-by-side comparison of the two products. Be careful that the serving size is TWO tablets, not one. Tablets are not coated, so they tend to grind each other, leaving particles at the bottom (not recommended for carrying with you).

I thought I was taking enough Magnesium because it’s present in some of the supplements I take, including a Sleep Magnesium. In discussions with my different health providers I always get asked am I taking enough Magnesium and it turns out that I haven’t. It plays a role in bone & joint care as well as the nervous system, so this is my second bottle of these tablets, and in researching different options I went for this as being good value for money
This and some other supplements were recommended by my neurologist to help with migraine prevention. After a few weeks, I've noticed a reduction in symptoms so I feel it has helped, I just wish the pills weren't as large and uncoated. Well worth it when weighed against a migraine or the side effects of some prescriptions, though.
