"Health salts" = Epsom salts?

[Invalid Stout]

I was looking for Epsom salts but all I could find were 'health salts' containing citric acid, bicarbonate of soda and magnesium sulphate. Can I add these to my liquor? Will the other ingredients have any negative effects?

Can't say for sure but I would be worried about the citric acid and bicarb messing with the pH

There's magnesium in malt, you only need it in trace amounts.... i'd leave it out personally and stick to CaCl2 & Gypsum
