I'm not sure I would agree with must... I do take a magnesium supplement and sometimes add some salt to my coffee (as well as liberally applying it to food) but I don't take anything else and have had no ill effects.
Ok well shall we change must to advise.
Yes u might be lucky and not of had keto flu.
But the protocol will generally stop it in its tracks.
Wouldn't u rather have a preventive measure?
This doesn't apply to someone following keto diet for some time.
When your first start out your body is in a shambles and changing alot of its processes at cellular level.
Your ability to hold onto electrolytes and minerals deminishes and takes time to reach equilibrium.
So just make sure u have them covered daily.
But d3 and vit k2 i would advise to take daily too
