You might be interested in taking a magnesium supplement, but do you know which one is best for your body’s needs? Different types of magnesium vary in terms of their absorption, desired effects, and potential side effects, since not all magnesium supplements are created the same. Choosing the right magnesium supplement can be overwhelming, so here’s what you need to know to help narrow your search.

Mega Magnesium Glycinate 3-in-1 contains 100% of Magnesium Glycinate from MagActive®, an exclusive, enhanced absorption magnesium. Click here to learn more.

Magnesium is an essential mineral, which hundreds of everyday body processes rely upon. Everything from energy production, to regulating muscle health, to supporting the nervous system and helping maintain a healthy heart and cardiovascular system. Magnesium cannot be made in the body and needs to be obtained from our food and water. Nuts, seeds, green leafy vegetables, and unprocessed wholegrains are rich in magnesium.¹ Legumes, fruit, meat and fish are also good sources.¹

Despite how essential magnesium is for the body, plenty of people are not getting enough through their diet. Statistics show that one in three people aren’t meeting their daily magnesium targets.² The dietary intake of magnesium in the western world is decreasing in part due to the consumption of processed foods, which have a much lower magnesium content.¹ Ongoing stress can also deplete the body of magnesium,³ compounding the problem.

The potential signs and symptoms that the body might need more magnesium include:⁴

• Loss of appetite
• Muscle cramps and mild spasms
• Fatigue and weakness
• Sleepiness
• Pins and needles

People who lead stressful, busy lives might have higher magnesium needs. Not only does stress deplete the body’s magnesium levels, but low magnesium levels also increase the effects of stress, thus leading to a vicious cycle. Athletes might also be at risk of deficiency due to an increased utilisation of magnesium during exercise.⁵ In fact, magnesium requirements are 10-20% higher for regular exercisers than sedentary people.⁵

If you think you’re not getting enough of this vital nutrient through food, you might consider a magnesium supplement. There are many different forms of magnesium on the supplement market including magnesium oxide, magnesium citrate and magnesium glycinate - and some are more efficient than others.

Each type of magnesium has different properties. They vary depending on their bioavailability (how easy it is for the body to absorb them) and their tolerability. For example, the common magnesium form, magnesium oxide has much lower bioavailability than its counterparts and can also have a laxative effect.⁶

Magnesium citrate has better bioavailability than magnesium oxide and may be a better choice.⁷ However, when it comes to superior magnesium supplements, magnesium glycinate prevails. This is because magnesium glycinate is bound to the amino acid glycine, it bypasses the typical digestive roadblocks that cause stomach upset. This makes it incredibly gentle on the stomach with significantly higher absorption potential compared to standard forms like magnesium oxide.¹⁰

Magnesium glycinate (MagActive®) consistently demonstrates superior absorption when compared to magnesium oxide and magnesium citrate. It is also better tolerated, reducing the common bowel effects experienced with other magnesium forms.

Whether you take magnesium tablets or magnesium powder is a matter of preference and whatever is easiest for you to incorporate into your daily routine.

Magnesium powder might suit older people who have trouble swallowing tablets or athletes/exercisers who want a rehydration drink after a workout. Other people might find magnesium tablets to be more convenient.

Ethical Nutrients has a range of magnesium supplements to suit a variety of needs. All magnesium products feature the high-strength, easily absorbed and tolerated magnesium glycinate, MagActive®, and come in a range of capsule, tablet, and powder formulations that work with your body to assist energy production and muscle health or relieve the symptoms of stress and support healthy sleeping patterns.

If you're new to taking magnesium, Mega Magnesium Glycinate 3-in-1 offers a premium, streamlined solution. Formulated in an easy-to-swallow capsule, it delivers 100% of its magnesium from MagActive® magnesium glycinate. By taking it daily, you can efficiently target the three most common areas of magnesium depletion:

• Muscle Relaxation: Helps to relax tense muscles and directly relieve frustrating muscle cramps.

• Healthy Stress Response: Supports the nervous system to help your body manage the demands of a busy, stressful lifestyle.

• Energy Production & Wellbeing: Fuels cellular energy production to combat fatigue and support your overall daily vitality.

This 3-in-1 formula ensures your body actually absorbs what you give it, helping you break the cycle of stress and depletion with just one simple daily habit.
