Frequently Asked Questions

What are the benefits of magnesium?

Magnesium is an essential mineral that's involved in more than 300 functions in the body. Magnesium has many research benefits including muscle cramp relief, muscle relaxation, sleep benefits, stress management and relief from migraines.

What is magnesium diglycinate?

Not all magnesium's are created equal. Magnesium diglycinate is one of the best forms of magnesium because it is easily absorbed. When compared to magnesium oxide, magnesium citrate & magnesium sulphate, magnesium diglycinate has fewer gastrointestinal side-effects (such as stomach upset & diarrhoea) due to its enhanced absorption.

Why take a magnesium supplement?

1 in 3 Australians don't get enough magnesium in their diet2. A magnesium supplement can be helpful if you need to support your muscles (relieve cramps or for exercise recovery), hormonal balance, sleep or for stress relief.

What time of day should you take magnesium?

Magnesium can be taken at different times of day depending on the benefit you are looking for – morning may be more useful for stress relief and muscle recovery after exercise, while night might be more beneficial for sleep or muscle cramp relief.

Can magnesium help you sleep?

Magnesium has long-researched benefits for sleep. Magnesium also helps relax the body by alleviating muscle tension, which in turn can put you in a more relaxed state. This allows for a smoother transition to sleep and less disturbance by muscle cramps, mild spasms & discomfort.

What are the signs of magnesium deficiency?

1 in 3 Australians are magnesium deficient2 which shows up in many ways. The main symptoms people experience from magnesium deficiency are a lack of energy, poor sleep quality, PMT symptoms and muscle weakness, cramps & spasms.

Should I take magnesium tablets or powder?

Magnesium is offered in both powder & tablet form, neither of which impact the effectiveness of the magnesium. Some people find magnesium tablets more convenient, while others prefer to incorporate magnesium powder in their drinks (i.e. morning smoothie, warm 'tea' at night, etc).

Does magnesium help muscle cramps, including leg cramps?

Magnesium is proven to reduce & relieve muscle cramps, including leg cramps (even those suffered at night). It's important to look for a high quality, easily absorbed form of magnesium such as magnesium diglycinate for the most benefits.

Why is magnesium important for women?

Magnesium is a crucial mineral for everyone, but it has been shown to be especially beneficial for women. It supports various bodily functions and helps alleviate symptoms of PMS, regulate stress, improve sleep, and relax muscles. Ensuring adequate magnesium intake can significantly enhance overall wellbeing and hormonal balance in women.

What happens when a woman's hormones are out of balance?

When a women's hormones are out of balance, it can lead to a variety of physical and emotional symptoms. A magnesium deficiency can further disrupt this delicate hormonal balance, leading to increased stress levels, fatigue, sleep disturbances, and muscle aches. Ensuring adequate magnesium intake can help restore balance, supporting healthy reproductive hormones and maintaining optimal oestrogen levels.
