How Long Does Magnesium Take to Work? What to Expect

If you've just started taking magnesium you might be asking yourself how long does magnesium take to work. The answer to that is it really depends on why you're taking it, your diet, the form of magnesium you're taking, your routine and your individuality. Some people will see a difference quite quickly, others will need to take it consistently for a longer period of time before they start to see any real magnesium results.

How long does magnesium take to work?

There's no one timeline for everyone. Magnesium is a vital mineral involved in so many of the body's normal processes (muscle and nerve function, energy metabolism, electrolyte balance etc). If your diet is already providing you with adequate magnesium then you may not actually see any real difference from taking a supplement. If your intake is lower then you may well be able to see a difference over time with a consistent routine.

When it comes to how long magnesium takes to work, it's all about building a routine rather than expecting it to have an effect straight away. Some people will see a difference in their day to day routine within days or weeks, others will take longer. The best thing to do is just to stick to the instructions and see how you feel over time.

What Affects Magnesium Results?

There are a number of things that can affect magnesium results including the type of magnesium supplement you're taking, the amount you're taking, your diet, your lifestyle and the reason you're taking it. Your current level of magnesium intake is important too as supplementation is not a replacement for a good balanced diet. Individual differences in terms of digestion and absorption will also play a part in how you respond. Your daily habits are of course important as well. Your sleep pattern, hydration, level of activity, stress, caffeine consumption and general nutrition will all have an effect on how you feel. If you're using magnesium as a sleep aid for instance then it should be part of a good overall healthy sleep routine rather than a magic bullet on its own.

Magnesium for sleep: what should you expect?

Loads of adults will go for a magnesium supplement as part of their evening regime as it's known to support normal nervous system and muscle function. It's worth bearing in mind that a magnesium supplement for sleep is not going to be a magic sleep aid and won't necessarily fix your sleep issues. 

If you're using it as part of a regime to help you get a better night's sleep then consistency may be more important than any particular number of hours or days. Simply take it as per the instructions on the pack, stick to a consistent bedtime, reduce your screen time prior to going to bed and make sure your bedroom is comfortable and quiet.

How long does magnesium glycinate take to work?

A magnesium glycinate is magnesium bound to glycine. It's a popular choice with adults looking for a simple magnesium supplement as part of their daily wellness regime, particularly those who take it in the evening.

The timeline isn't necessarily dictated by the form. A magnesium glycinate supplement doesn't have a set 'works in X hours' time frame. Your own nutritional status, the size of your serving, your diet, your lifestyle and the reason you're taking it will all have an impact on what you may or may not see. Always go by the product label rather than increasing your serving size because you don't necessarily see results straight away.

What about magnesium supplements for women's health?

Women may well view magnesium as part of a general nutritional and wellbeing approach given its role in normal muscle and nervous system function and normal energy-yielding metabolism. Magnesium supplements for women's health should be chosen on the basis of individual nutritional requirements rather than on the basis of marketing claims.
