Made no difference to my sleep

found no improvement in my sleep

I struggled with sleep during the morning and day time

Magnesium13%+0.84

took it two hours after my breakfast due to drinking tea which would gave a negative effect on the magnesium

you have to be aware that you are taking massive doses of magnesium if you take it according to the instructions, way a over the recommended daily intake and for some people this causes abdominal pain and other issues, and may not be good for heart and kidneys on a long term basis

I thought, If Arnie recommends this type of magnesium then why the hell not give it a spin myself
