I buy my Jigsaw from eBay US (I'm from Argentina)... In my case, I take 2 tablets a day (morning/noon), and with that I have covered much of the day (thanks to the time release system)... Then, at night, I again take magnesium but in the glycinate form, that helps to get a deeper sleep...
Thus, a Jigsaw bottle lasts me 4 months... And the glycinate alternatives are quite affordable...
And besides this, I always put my filtered water in a large glass bottle (4 liters), to which I add 1 gram of magnesium chloride flakes per liter ... I use this water to cook and drink ...
After several testings I found the concentration of 1 gram per liter to be ideal: it doesn´t alter the taste of water and doesn´t have a laxative effect...
In the case of your father, perhaps you should consider the option of giving him Magnesium taurate, a form of magnesium that is focused on cardiovascular health... The extra taurine (405 mg per capsule) helps the heart function better...
A good option (and I'm tempted to try it) seems to be this brand:

If you look at the reviews, you'll find things like:
"Taurine definitely helped with both arrhythmia and heart failure symptoms."
"good for heart palps"
"Lowered blood pressure"
I consider it a good choice since I have not seen the inclusion of taurine in your father's regimen...
