The website lists only active ingredients for Magmin, listing all ingredients would be more useful for 3 reasons.
1.I thought calcium needed to be taken with magnesium and was looking for all ingredients in the product.
2. I am also looking to compare Magmin with an alternative product
3. People with intolerances, such as coeliacs, may appreciate knowingall ingredients.

I am 32 weeks pregnant and I am currently taking 2 tablets daily of Blackmores Pregnancy & Breastfeeding Gold.
As there is some magnesium present in this multivitamin already, I am wondering if MagMin is safe and beneficial to take while pregnant to assist me with anxiety and restless legs. I do NOT have a known deficiency of magnesium.

*Also, I am currently consuming 2000IU of vitamin D and 650 mg of Iron daily as prescribed by my doctor.

Hi, I am deficient in magnesium but high in potassium, A lot of the magnesium supplements have potassium in them. Does Magmin contain any potassium please.
