Magnesium can bind to compounds called phytates which the body finds hard to absorb. But this chelated form protects the magnesium, so it gets to where your body needs it most.
A magical mineral

Magnesium is needed for over 300 processes in your body, from normal cell division and electrolyte balance to normal function of the muscles and nervous system.
Fills nutritional gaps

It’s the fourth most abundant mineral in the body. Yet many of us don’t get enough, thanks to modern industrial agricultural practices that deplete the soil of naturally occurring magnesium.
Recommended by experts

“It’s so rare to find a supplement that ticks all the boxes when it comes to quantity (dosage) and quality of ingredients for pregnancy’s nutrition needs. So, I’m always very happy to recommend Inessa’s Pregnancy Multinutrients to all my pregnant clients. I particularly like that Inessa contains choline, a nutrient which is just as important as folate for neurodevelopment of baby. Other supplements that I have recommended from the Inessa range are Advanced Omega 3 and Inessa Magnesium.”

“I specialise in corporate, sports & fitness, and anti-inflammatory nutrition. As someone who has an autoimmune condition, I’ve used Inessa's Biosoothe, Magnesium, and Advanced Biotic Complex supplements. I noticed the difference within few days of taking these. What I love about the products is that they of high quality, therapeutic and also their Advanced Multivitamin is certified with Informed Sport. As a registered sports nutritionist, this is very important to my athletes.”

If you’re unsure about whether you should take magnesium, please talk to your health care provider.

Magnesium may interact with certain medicines. If you are taking prescribed medication, you should always check with your doctor first and read the information leaflet with your medicine(s) for contraindications.

From the founder

“There are so many different types of magnesium you can take. But because they’re all so different in terms of bioavailability, some are much more effective than others. For example, magnesium oxide - a cheaper, commonly found form of magnesium in supplements - is actually quite poorly absorbed. To harness all of magnesium’s wonderful benefits it’s best to take it in a form your body can actually use well. That’s why it was so important to include all three types of magnesium we use in our blend. They all work in different ways, to offer a range of benefits, and ours is one of few products on the market to include magnesium threonate. It’s the only form of this mineral known to cross the blood-brain barrier, but is often missed out of formulas because it’s more costly.”

Frequently asked questions

Although our magnesium can be taken any time with food, if you are using it as a sleep aid, or an exercise aid, take around thirty minutes before you hope to sleep or exercise.

No, magnesium will not cause drowsiness if you take it during the day. Magnesium works to support your energy levels, anxiety and mood during the day and can be taken in the evening to promote sleep.

Inessa Magnesium is less likely to cause gastrointestinal upset than other magnesium products, as we use chelated forms that are more gentle on the gut. If you’re at all concerned, or have a particularly sensitive stomach, we would recommend you start taking just one capsule per day instead of two.

Unless you have a medical condition that means you should not take magnesium, Inessa Magnesium is safe to take with other products that also contain magnesium. However, it’s best to be cautious - if you take in too much of this mineral through a variety of products, you could get a tummy upset.

Take one to three capsules per day with food and a glass of water, or as directed by a healthcare professional. If you have not taken magnesium before or have a sensitive gut, we recommend starting with just one capsule per day. Do not exceed the recommended intake. Do not use as a substitute for a varied diet and a healthy lifestyle.

Inessa Magnesium is deemed safe for most people but if you have a medical condition or are taking prescribed medication, you should always check with your doctor first and read the information leaflet with your medicine(s) for contraindications. Food supplements should not replace a balanced and varied diet and a healthy lifestyle.
