It's ok, it'll do.

I get it for the magnesium and vitamin D3 mainly but the zinc is also helpful and the calcium a bonus. I get this because it's cheaper like this than separate but possibly more effective products. I've had better magnesium, D3 and zinc products individually. I have noticed my eyes still twitches which indicates it's not enough or the right sort of magnesium for me all the time. I do notice the difference without magnesium and D3 altogether though.
