How long it takes to feel the benefits of a magnesium supplement can really vary from person to person.
It depends on factors like your starting levels, diet, how well your body absorbs magnesium and even your individual sensitivity.
One thing to consider though, is that it's not so much about you being able to feel immediate noticeable benefits.
It's more about knowing that you're giving your body an essential mineral that it needs to function at its best.
If you're not getting adequate amounts of magnesium in your diet through food alone, then magnesium supplements become absolutely essential.
Some people notice a difference within a few days, while for others, it can take a few weeks or even months of consistent use.
