Magnesium is one of the most quietly important minerals in the body. It plays a role in hundreds of everyday processes, from helping your body release energy from food to supporting normal muscle and nerve function, restful sleep, and a calmer response to everyday stress. Despite how essential it is, many South Africans simply do not get enough through diet alone. Busy lifestyles, processed foods, and soil mineral depletion all mean magnesium levels can quietly dip lower than ideal.
That is where a good magnesium supplement can help fill the gap. But walk into any health store and you are met with a wall of options: glycinate, citrate, threonate, complexes, oils, and more. This guide explains the main types of magnesium, what each is best suited to, the gentle everyday benefits, and a hand-picked selection of magnesium supplements available at Anadea.
Types of magnesium explained
Not all magnesium is the same. Each form is bound to a different molecule, which changes how well it is absorbed and what it tends to be used for. Here is a quick, plain-language overview:
- Magnesium glycinate – bound to the amino acid glycine. Known for being gentle on the stomach and a popular choice for sleep and everyday stress support.
- Magnesium citrate – well absorbed and often chosen by people thinking about digestion and occasional muscle cramps.
- Magnesium L-threonate – a newer form studied for its ability to cross into the brain, often favoured by those interested in focus and mental clarity.
- Magnesium oxide – an inexpensive, widely available form. It contains a lot of magnesium by weight but is absorbed less efficiently than the chelated forms.
- Magnesium complex – blends two or more forms together so you get the strengths of each in a single capsule, which is handy if you are not sure where to start.
Magnesium benefits
Magnesium contributes to a wide range of normal body functions. Some of the gentle, everyday areas it supports include:
- Helping the body release energy and reduce everyday tiredness and fatigue
- Supporting normal muscle function and comfortable, relaxed muscles
- Contributing to normal nerve signalling and function
- Supporting a calm mind and a healthy response to everyday stress
- Helping promote restful, good-quality sleep as part of a wind-down routine
- Contributing to the maintenance of normal bones and teeth

Frequently asked questions
Which magnesium is best for sleep?
Many people reach for magnesium glycinate when sleep and relaxation are the priority, as the glycinate form is gentle and often associated with a calmer evening wind-down. A glycinate or glycinate-based complex is usually a comfortable starting point.
When should I take magnesium?
It comes down to your goal. If you are using magnesium to support relaxation and sleep, taking it in the evening is common. For general daily support it can be taken with a meal at whatever time suits your routine best.
Are there any side effects?
Magnesium is generally well tolerated. Some forms, particularly less-absorbable ones taken in higher amounts, may cause loose stools in some people. Gentle, chelated forms like glycinate tend to be easier on the stomach. If you are pregnant, nursing or taking medication, it is best to check with your healthcare practitioner first.
