100% Magnesium Citrate Powder

This product is - I believe - Trimagnesium Citrate, it's a cheaper commercial form of Magnesium Citrate. It does give you more Magnesium per gram. The downside is that its solubility in PH neutral water is poor. My solution is to add 1/4 teaspoon Malic Acid (maybe a bid less) to each teaspoon of Magnesium Citrate. Gets rid of the taste and in hot water it dissolves completely.

"I love this supplement. I take a 1/4tsp upon waking, and at bedtime - with a bit of water. It's a little bit sour, and tastes fine. Magnesium calms me like nothing else, and I sleep really well now because of it. It's also very good for your bowels and promotes regularity. Plus, for women, it is fantastic for eliminating monthly hormonal problems - take an extra 1/4tsp per day for days 14-28 of your cycle (with 50mg B6). You lose a lot of magnesium when you sweat (and exercise heavily), and you need more when you are stressed. I increase the dose by 1/4tsp per day at these times. I can't recommend it enough. It's such a fantastic mineral. Google it, to confirm this."

Interesting one this - I read about magnesium making you sleep better so I thought I would put this to the test. I used my watch to monitor my sleep for a week then I did the same but taking the guided amount 1-2 hours before bed.  So it seems that it definitely helps. My time asleep improved and I had more deep and REM sleep overall.  For the price not a bad supplement to add to a healthy diet !

Just throw it down with a bit of water. Doesn’t mix well but worth taking for the improved sleep. 

I have bought this product. I use 2.5 g daily, works great to reduce muscle cramps and gives overall energy in both mind and body. I dislike magnesium as pills, so this is great. It doesn't mix 100%, but so what? Give it a stir and flush it down the hatch. It's worth it.
Goes Well With:
water, orange juice

Very reasonably priced, does what it says. I've been taking this product for about a year now and this is cheapest on market for quantity provided. As we get older women's bodys need more magnesium to support the nervous system. I've been sleeping better and it's helped with constipation too. Happy customer.

Definately helping with sleep. Great value and excellent swift service. I will order again.

I mix with fizzy Vit. C lozenge as helps to mix better.

initially had a bit of trouble getting it to dissolve properly. i eventually settled on hot water from a just boiled kettle and some robinsons lemon squash, the cordial stuff dissolves right easy with a bit of a stir and it's working as it should. I previously was mixing the water with the juice of a lemon but that tasted a bit ick, wasn't great for my teeth and (whatever else is in the lemon squash) didn't dissolve nearly as well. i can't really compare it to many other magnesium supplements but this works so well for me I don't see myself trying any others anyway. it really is fantastic stuff, I feel so much better for having tried it.

I never write reviews, but this stuff is so awful I just have to add a warning.. Gave this a go as it's *so* much cheaper than the Mag citrate I usually buy, but it's like a completely different substance! It should easily dissolve, fizzing slightly in warm water, and taste a bit citrusy, almost pleasant to drink - the MyProtein version is a courser powder that just sinks to the bottom of the glass. It's like trying to eat fine sand, a horrible gritty texture that can't be hidden by mixing it into foods. It doesn't really taste of anything except disappointment, but there's a slight scent of stale pond water after mixing. I hate throwing things out, but have no idea how to get through the bag!

Nothing

It is a good product, it is hard to dissolve, but it is a perfect magnesium replacement
