Magnesium is an essential mineral involved in more than 300 enzymatic reactions in the body. It helps maintain normal muscle contraction, nerve function, and energy metabolism, which are important for people with higher physical demands.

Magnesium occurs naturally in foods such as leafy greens, legumes, nuts, and whole grains. Training load and modern eating patterns can make it difficult to reach recommended intakes. Supplementation can help maintain adequate intake to support muscle relaxation, recovery, and overall wellbeing.

Nutrition Warehouse stocks more than 60 magnesium supplements across every major form and format, from single-form magnesium glycinate through to multi-form blends, plus tablets, capsules, powders, chewables, and topical creams.

Magnesium Forms Explained

The form of magnesium refers to what the mineral is bound to, and it affects how well the magnesium is absorbed and how it sits with your stomach.

• Magnesium glycinate – Magnesium bound to the amino acid glycine. Well absorbed and gentle on digestion, which makes it a popular choice for daily use and evening routines. Also sold as bisglycinate or diglycinate.
• Magnesium citrate – Magnesium bound to citric acid. One of the most widely used organic forms, commonly chosen for muscle support and cramps.
• Magnesium amino acid chelate – Magnesium bound to amino acids. Another well-absorbed organic form that appears in a large number of blends.
• Magnesium L-threonate – A newer form usually selected for cognitive support and sleep rather than muscle recovery.
• Magnesium orotate and aspartate – Organic forms that appear most often as part of multi-form blends.
• Magnesium oxide – Delivers a high amount of magnesium per tablet, but is less readily absorbed than the organic forms above.
• Magnesium chloride – The form used in topical creams, applied to the skin rather than taken orally.

Magnesium Tablets, Capsules or Powder

Magnesium tablets and capsules are the simplest option to stay consistent with, need no preparation, and travel well, which is why they suit busy schedules and daily maintenance. Magnesium powders let you take a larger dose in a single serve, mix into water or a shake, and usually come flavoured, which suits anyone who would rather not swallow tablets or who wants a post-training option. Chewable tablets are worth a look for kids or anyone who struggles with either.

How Much Magnesium Do You Need

Check the elemental magnesium figure on the label rather than the weight of the magnesium compound. A product listing 3g of magnesium glycinate may supply 300mg of elemental magnesium, and it is the elemental number that tells you what you are actually getting. Most magnesium supplements in Australia sit somewhere between 100mg and 400mg of elemental magnesium per serve. Recommended dietary intakes vary by age and sex, so check the reference values linked below and follow the directions on your product label.

Choosing the Right Magnesium for Your Routine

• For daily balance – citrate or glycinate are popular for consistent support.
• For post training and hydration – powders using citrate or amino acid chelate are easy to mix.
• For sleep and winding down – glycinate or a sleep-specific blend taken in the evening.
• For convenience – capsules or tablets suit busy schedules.
• For sensitive stomachs – glycinate is the form most often recommended as being gentle on digestion.
