Magnesium is one of those nutrients we often forget about until we have a problem. It’s actually really important for a whole range of processes in the body, and probably best known for its role in supporting healthy muscles and nerves. You may not be aware that you are consuming magnesium in your everyday diet, but if you commonly eat green leafy vegetables, legumes, nuts, seeds and wholegrains, these are good sources of magnesium. Our bodies absorb magnesium in the gut and it is then stored in our bones (50-60%) and in soft tissues like our muscles.1,2.

Different forms of magnesium are recommended depending on need.  2

For example, magnesium citrate tends to be well absorbed by the body and can be recommended for those with low dietary intake, whilst magnesium glycinate is also well absorbed, it has shown to be well tolerated by the stomach 3,4.

Look for additional ingredients that might support your needs such products with bruise healing herbs for muscle recovery after sport.
