Radiance Magnesium Powder is highly bioavailable, quick acting magnesium powder in a pleasant old-fashioned lemonade flavour.

Magnesium, a mineral required for several hundred functions in the body, is especially important for muscle and nerve function, normal blood pressure and heart rhythm, healthy immune function, bone density, healthy blood glucose levels and is involved in energy metabolism and protein synthesis.

A deficiency in magnesium can result from high levels of stress, mineral deficiencies in New Zealand soils and a diet high in refined foods and lacking in food sources of magnesium (nuts, seeds, whole-grains, green foods).

Magnesium is also an ideal supplement for athletes and those who exercise regularly -it acts as an electrolyte, helping the balance of fluid in the cells and around themand is used in muscle contraction and relaxation. Magnesium is rapidly used up during exercise. Magnesium taken post aerobic workout has shown to reduce cortisol and its damaging inflammatory effects.

Radiance Powdered Magnesium offers rapid delivery and absorption for faster replenishment of magnesium stores.

Supplementation is indicated for anyone with magnesium deficiency symptoms including cramping, restlessness, poor sleep and cardiovascular problems. It is also recommended for athletes, those under stress and thoseexperiencing shortness of breath, poor blood sugar metabolism and those with diets low in whole grains and green foods.


1-2 heaped teaspoons (5-10g) daily stirred into water, juice or soft food. Can be taken before bed to support deep restful sleep.

helped with cramps Review by
  • star

I used to wake up from cramps and numb hands, sometimes few times a night. Since I started taking magnesium this problem has reduced to once a week. Great product to take post workout as well.
It can be challenging to make it dissolve in water though. Otherwise good product. I am ordering more tonight.

I take this every day in a smoothie post exercise. I feel that it aids my recovery and I no longer get night cramps in my legs.

Love the taste, mixed with warm water it's easy to dissolve. Works well for tired cycling legs and sleep.
I only take at night.

  • star

I have used this product for about a year and highly recommend it. I had many sleep problems and found this helped from the very first night I took it. I found that I slept much deeper and longer than usual. The NZ diet is quite low in magnesium and other trace elements so often our levels are depleted and this really helps to normalize everything again. Mix in tepid water so it dissolves better.

I totally recommend this product to anyone having sleep difficulty. I've tried many different magnesium powders and tablets. This is the best I've found. I take it to help me sleep, and it works a treat! most other magnesium powders have vit B in them (so aren't good for people wanting a sleeping aid). This is the only powder I've found that doesnt have vit B in it. It doesn't taste amazing, but it tastes better than all the powders out there that use nasty chemicals to flavour them.

Tastes fine, very easy to swallow, works fast to help relieve cramping. I would recommend to anyone that's having muscle problems

This product is great! I'm really impressed and find the quick acting formula more effective than the tablets. I take it an hour before bed, it helps me to sleep deeply, has relieved tight muscles in my shoulders and eases period pain which I usually get quite bad. I don't mind the taste either.

My natural health professional put me onto this and I'm pleased with the results. I'm not waking in the night with leg cramps, sleeping better and the taste is way better than some of the other stuff I have to take.
