The Magnesium Gut Connection: Digestive Support & Regularity Explained
Gut Health
Magnesium is a vital mineral which is involved in over 300 enzymatic reactions in the human body.1 Of all of these important functions, gut health support and digestive wellness are up there in terms of its major benefits. Find out more about how magnesium can benefit your wellness and regularity below.

 

Why is Digestive Wellness so Important? 

The human body processes the foods we eat via digestive processes from when food first enters our mouth, until it reaches the large intestines, where the waste is packaged up for excretion. Vital nutrients are digested and obtained from our foods that we can’t synthesise in our body. Waste and toxins that the body doesn’t need are processed and removed via our bowel motions. 

Digestive wellness is crucial to ensure the above processes occur, otherwise we may become nutrient deficient, or, at the other end of the spectrum, we may accumulate waste and toxins in the body which can be detrimental to our health. Promoting bowel regularity through a variety of gut health support mechanisms is essential.

The Role of Magnesium in the Body 

Magnesium plays a multitude of key processes in the body including:

   Supporting energy production

   Aiding healthy sugar metabolism

   Relieving muscle cramps when dietary intake is inadequate

   Maintaining nervous system health and function

   Supporting healthy heart function1

But it’s magnesium’s role in digestive support, wellness and regularity which are some of it’s most important benefits.

Magnesium for Digestion

Magnesium’s digestive support is achieved by encouraging regular bowel motions and elimination, which helps to relieve uncomfortable bloating. One of the ways it performs this action is by promoting peristalsis, helping the smooth muscles in the digestive tract to relax and contract in a coordinated manner, moving food, and eventually, faecal matter through. 

Magnesium for Bowel Regularity

Another way that magnesium provides gentle digestive support is by softening the stool, and promoting regular bowel movements. While there are many forms of magnesium that can be beneficial for digestive wellness, magnesium oxide in particular has been shown to provide occasional constipation support.

Magnesium oxide is a mineral compound which combines magnesium and oxygen ions. It has been traditionally used as a natural approach to constipation in East Asia since the 1800s.2 Magnesium oxide exerts this effect in the bowel via a process called osmosis, which draws water into the intestines from surrounding tissues, increasing the water content and volume of the stool, making it softer and aiding elimination and bowel regularity.2

Introducing Micronutrition OxyCleanse®

OxyCleanse® is a science-backed formula which contains over 3g heavy magnesium oxide per dose. Its high-strength formula provides occasional constipation support through its unique osmotic action, also relieving uncomfortable bloating. Magnesium oxide also aids wellness and regularity by helping to soften the stool, and supporting healthy energy production - all part of a well-balanced approach to digestive wellness. 

OxyCleanse® is a vegan formula which is free from dairy, gluten, soy, eggs and nuts and contains no excipients. It is third-party tested and is proudly formulated and manufactured in Australia.

When Should I Speak With a Healthcare Professional?

OxyCleanse® is a gentle and effective formula, suitable for short-term use. If you are having issues with constipation which are extending into the longer term, or are experiencing severe abdominal pain or cramping, blood in your stool or nausea and vomiting, you should seek the advice of a healthcare professional.

Top 4 Tips for Promoting Healthy Digestion and Bowel Regularity:
1. Stay hydrated:
water helps to bulk up your stool, promoting its excretion. Be sure to drink 2-3L water per day and avoid beverages which can dehydrate you including alcohol, tea and coffee.

2. Eat enough fibre: fibre from whole grains, lentils and fresh fruits and vegetables aids regular bowel motions. Some of the foods highest in fibres include wholemeal pasta, carrot (unpeeled), corn, rolled oats and broccoli.

3. Keep on moving: exercise encourages bowel motility, keeping you regular. Aim for at least 30 minutes a day of walking, running, resistance training or mobility and stretching.

4. Manage your stress: stress can affect your digestion, wellness and regularity, so prioritise stress management and regular relaxation whether that be breath work, mindfulness exercises, reading a book or chatting to a friend.3.4
