I recently ordered 3 bags of this, and used it for a bit, but got suspicious when it wouldn't dissolve. I had a chemical engineer look at it, and this simply isn't magnesium citrate. It might be some sort of calcium powder, but not sure. Magnesium citrate dissolves completely in water and has a clear taste of citrate. Whatever it is I got doesn't dissolve in water, and has no real taste. Vinegar dissolves some of it, when I tried. It's possible it's just a bad batch and a mixup in production, but until they fix this mistake, I would not recommend buying this mystery 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.

Malic Acid

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.

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.
Goes Well With:
lemon squash hot water

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

Purchased this and had tried taking it with water but doesn't dissolve well so have to keep swilling glass with water to get full dosage but tastes absolutely vile. Tried as suggested by another reviewer with lemon squash but still tasted as vile. In the end i purchased a capping kit and capsules to make my own tablets :) Haven't been taking it long enough to give any benefits but at least i can take it now :)

Mixability is really truly poor and this particular magnesium citrate powder doesn't have that characteristic acidic/lemon taste to it like all the other magnesium citrate powders I have used. I use magnesium citrate as an osmotic laxative and where I only had to use one tablespoon with other brands, I don't even get the same results with two tablespoons with this magnesium citrate powder. CONCLUSION: I think this is a extremely low quality product that does absolutely nothing

"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."

An extremely cheap and effective source of magnesium. Worth noting that this product is trimagnesium dicitrate, a cheaper form of magnesium which isn't soluble in water — this means it's tasteless, although it's like drinking sand. Much better than the other bitter or metallic tasting forms.
