    Magnesium: The Mighty Mineral

    Magnesium is one of your body's most important nutrients: a naturally-occurring mineral found in every cell in your body that plays a crucial ‘helper’ role in nearly all essential biochemical reactions.

    While magnesium is naturally present in many foods, as an "essential" mineral, our bodies don't produce magnesium on their own, so our reserves need to be constantly replenished through diet or supplementation.

    Studies suggest that between 10-30% of us may be magnesium deficient which can impact your stress levels & sleep quality - plus has been linked to diabetes, heart disease & depression.

    Frequently Asked Questions

    Yes magnesium is an ideal supplement to help support good sleeping habits. It plays an important role in your nervous system & offers soothing qualities which can help you to wind down before getting a good night’s rest.

    Many brands will label a product as magnesium citrate but it will actually be a mixture containing a large amount of magnesium oxide which is less bioavailable. When magnesium citrate is mixed with magnesium oxide it is called “buffered”.

    Puro Magnesium is made with true 100% pure, "non-buffered" magnesium citrate for superior bioavailability and effectiveness.

    Our true non-buffered magnesium citrate is gentler on your gut & less likely to cause digestive issues or gastrointestinal than some types of magnesium used in other supplements.

    If your stomach is also particularly sensitive, we'd recommend starting with a lower dose and building up slowly.

    This product has been formulated to work well in partnership with our other products and so can be safely taken with other products in our range that don't contain large amounts of magnesium.

    Other popular supplements to pair this with include Puro Hormonal Balance & Puro Meno Complex (as magnesium helps your body absorb vitamin B6).

    If you are taking any medication or have specific health concerns, please always consult with your GP.

    Many people find taking Magnesium to be particularly beneficial if you regularly suffer from muscle cramps, menstrual cramps, stiffness or ‘twitchy’ restless legs.

    This is because it helps to support your nervous system - helping to regulate muscle contraction and relaxation. Plus it also contributes to healthy electrolyte balance and promotes physical recovery.

    Yes. This product is non-GMO and contains no gluten, wheat or dairy. We also use plant fibre capsules making this formula suitable for both vegans and vegetarians.

      Good for muscle aches and eye twitches

      Tried several other magnesium supplements and keep coming back to this one so far. Have Fibromyalgia so was looking into other supplements with Magnesium malate too to help with energy. But my they didn't help keep my eye twitch and muscle aches away.

      I have found this one great for muscle aches and pains and muscle twitches (keeps my eye twitch away).
