This is another good magnesium product from Australia, I used to use the lavender one years ago but I don’t think they still make that one. Anyway have a read through the FAQ page and then have a look at their products. You might find something that you need, and follow them on facebook as they answer your questions about the products and how they might be helpful for your health.
