Blackmores Bio Magnesium is a combination of magnesium, vitamin D3 and other co-factors to aid absorption, helping to ease tense, tired muscles and support normal healthy muscle function.

Magnesium also plays an important part in the normal functioning of muscle and nerve tissue. 


  • This product contains Pyridoxine hydrochloride which may be dangerous when used in large amounts or for a long time.
  • Pyridoxine-induced peripheral neuropathy is most commonly reported with doses of 1gm or more daily, taken for 2 months to 3 years.
  • Magnesium may decrease the absorption and efficacy of some medications. If taking tetracycline or quinolone antibiotics separate doses by at least two hours.
  • Pyridoxine may decrease the efficacy of some medications. Consult your healthcare professional before use if taking phenytoin or phenobarbitone (anticonvulsant drugs), or think you may be.

Adults: Take 1 to 2 tablets a day with meals, or as professionally prescribed.

Each Tablet Contains:

Magnesium oxide - heavy 440mg
Magnesium phosphate 175mg
   (equiv to total magnesium 300mg)

Magnesium is often deficient in New Zealand soils

I found both my husband and I had quite a few symptoms of magnesium deficiency so we started taking this year's ago and find it the easiest pill to swallow and a good dose to take and use it every day. No more muscle twitches ,better sleep and much more relaxed.

Good for cramping

Because of celiacs my body doesn't absorb enough nutrients even if I eat super healthily, and one of those nutrients that aren't absorbed properly is magnesium. Without bio magnesium I get cramps and muscle spasms throughout my body. Particularly annoying is the eye lid twitches, which last time they were really bad gave me a bruised, purple eye lid and all my friends thought I'd been in a fight or something. The bio mag keeps all of that at bay, I intend on taking it every day for the rest of my life. And it's wonderful to be able to buy it cheaply here with my other products.

Helps me sleep

I go through phases when my emotions or muscle tension keep me awake or wake me early. But if I take one of these before going to bed I always get a really good night's sleep and wake in the morning feeling relaxed and refreshed.

This did the trick

I got exactly what I was hoping for from this product: I take it before bed and my muscles relax, so the quality of my sleep is much better.
