Supplement Question

Hi all, 

I’ve been doing Keto for about 2 weeks and am down about 6 pounds.  I was still hungry so I’m trying Keto Burn which is BHB and helps a bit with hunger. My question is about taking a multivitamin also. I have one called Keto Core but it has about 200mg of magnesium which you need on a Keto diet. Just not sure if I should take both since the BHB has a good bit of magnesium. Any thoughts on these supplements or whether to take them at all?

Thanks in advance!
