The 5 Best Magnesium Supplements

Tablets scattered across a yellow table.

Magnesium provides many benefits to the body, being involved in more than 300 functions, including;

  • Muscle cramps & health
  • Healthy sleep
  • Energy production
  • Stress & mild anxiety management
  • PMS symptom relief
  • Ageing muscle support

Unfortunately, the average Australian diet does not provide enough magnesium to keep up with the amount of stress and muscular tension in our day-to-day activities. Below are signs of magnesium deficiency which may cause noticeable symptoms.

  • Cramps, spasms or weakness in muscles
  • Eye or other twitching
  • Shaking hands
  • Poor or prolonged exercise recovery
  • Difficulty falling asleep & poor sleep quality
  • Tension headaches

What to Look for in a Magnesium Supplement

Form equals function and not all magnesium forms are created equal. To get the most from your magnesium supplement, it’s important to look for a ‘magnesium glycinate’. Magnesium glycinate is a chelated form of magnesium, meaning it is bound to an amino acid (glycine) to assist absorption, minimise side effects (i.e. diarrhoea & stomach upset) and ultimately provide real results. Glycine is also necessary for healthy collagen to provide strength for your muscles, skin cartilage bones and ligaments.¹

Ethical Nutrients Mega Magnesium range is formulated with magnesium digylcinate (bound to two glycine molecules) so you can reap the benefits of magnesium and minimise the risk of uncomfortable side effects.

The Top 5 Magnesium Supplements

#1 For Muscle Health or PMS Relief: Mega Magnesium

A combination of high strength, easily absorbed magnesium glycinate with supporting nutrients, Mega Magnesium provides relief from cramps of all kinds – muscle cramps or cramps associated with premenstrual syndrome (PMS). An all-round formula, Mega Magnesium supports healthy muscle function and reduces the occurrence and severity of cramps and mild spasms.

#2 For Mental Chatter or Mild Anxiety: Mega Magnesium Relax

Made with easily absorbed magnesium glycinate and lavender oil, Mega Magnesium Relax reduces ‘mind chatter’ and relieves symptoms of mild anxiety. Regulating your response to stress, Mega Magnesium Relax is the ultimate relaxation companion that will help you regain a sense of calm without feeling sleepy. This makes it suitable for use during the day or night.

#3 For Deep & Restorative Sleep: Mega Magnesium Night

Combining easily absorbed magnesium glycinate with passionflower, Mega Magnesium Night supports healthy sleeping patterns, calming the mind and muscles in preparation for a sound night’s sleep. The glycine in the formula also has a calming effect on the brain and nervous system as well as lowering the body’s core temperature. Research shows that glycine before bed decreases the time to fall asleep, enhances sleep quality and assists to wake refreshed.¹

#4 For Energy & Fatigue: Mega Magnesium Energy

Formulated with high strength, easily absorbed magnesium glycinate and added B vitamins, Mega Magnesium Energy supports healthy energy levels and relieves tiredness when dietary intake is inadequate. Providing support to busy nervous systems, Rhodiola rosea has also been added to assist in alleviating life-stress symptoms.² It also has Acetyl levocarnitine hydrochloride which is also an amino acid which can be made in a healthy liver. Carnitine has an essential role in energy production which assists the body to use fats for energy. It also increases noradrenaline and serotonin for improved energy levels and brain function.³

#5 Muscle Support For People Over 50: Mega Magnesium Muscle Plus

Combining high strength, easily absorbed magnesium glycinate with HMB and vitamin D, Mega Magnesium Muscle Plus enhances muscle strength and function in people over 50 years old. HMB (Calcium beta-hydroxy-beta-methylbutyrate monohydrate) promotes gains in fat-free mass and strength in people over 50 years of age. Magnesium with glycine assists your body to produce creatine which has been shown to increase muscle size, strength, and power,¹ which is particularly important as we age – muscle mass declines by 1% per year on average from 30 years old. Mega Magnesium Muscle Plus is formulated to support muscle mass, strength and function and is ideal for people over 50 years old.
