Frequently asked questions

What is PMT?

Pre-menstrual tension also called pre-menstrual stress (PMS), is caused by the stress and discomfort associated with the menstrual cycle in women. Cramp Bark is considered a uterine decongestant. Signs of uterine congestion include bloating, cramping before menstruation as well as the delayed onset of a period. Magnesium can help to relieve the symptoms of menstrual cramps and tension headaches.

How do the nutrients support muscle function?

  • Magnesium is a mineral that is essential for muscle function and recovery
  • Vitamin B6 and Zinc contribute to the benefits of Magnesium in the body
  • Cramp Bark is known to treat muscle spasms

What else can I do to support healthy Magnesium absorption?

  • Avoid carbonated and highly acidic drinks
  • Reduce alcohol and caffeine intake and if you smoke cigarettes, stop
  • Drink plenty of water while exercising regularly

For how long should I take a Magnesium supplement?

That depends on many factors, if you experience PMT you can start taking it a few days before your period and until the discomfort has passed, you should consider long-term Magnesium supplementation if you exercise regularly and often get twitchy muscles or have a restless sleep.

Great product

Works for me

The NZPure Magnesium and Cramp Bark formula is just what I need. As part of my required health regimen, I take other medications that burn through my body's magnesium stores, so I use this product to avoid becoming deficient. The added zinc helps to keep zinc/magnesium in balance without more pills, and the cramp bark helps with my leg recovery following sports, as well as supporting other supplements I use to keep me functioning well as a man over 50.

Great product

I bought this to help me sleep but it has done more than that. I use it with MSM (same brand) and I dont get hormonal headaches, sore neck or bleeding noses anymore. I also sleep alot better. I take these two products about 1 hour before bed. Sometimes earlier. They are lovely to talk to on the phone as well.
