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.

Very positive so far

So far I have been enjoying these. They make me more relaxed and I don't have any negative reactions to them (I am normally unable to take magnesium tablets). I like this "reverse ratio", I think it's the best way to have them.

Brilliant Combination

Finally a tablet that is 2:1 Magnesium to Calcium, with the necessary Zinc for better absorption. It would have been ideal had they added Vitamin K2 also for the best absorption, but I feel I do get my daily amount of K2 in the vegetables I eat, being vegan I eat lots. I've only started taken these but I'm sure I feel my muscles aren't as tense as they used to be.
