  • Product Overview

    What is Magnesium Citrate?

    Magnesium is a mineral that can be found in a number of foods and is most prevalent in green leafy vegetables such as spinach, nuts and grains.

    Benefits of Magnesium Citrate

    Magnesium contributes to a reduction of tiredness and fatigue and to electrolyte balance. Magnesium contributes to normal energy-yielding metabolism and normal functioning of the nervous system. Magnesium contributes to normal psychological function, muscle function and normal protein synthesis. It also contributes to the maintenance of normal bones and teeth and also has a role in the process of cell division.

    Who is Magnesium Citrate suitable for?

    For anyone engaged in a long term physical training plan, getting the right dietary balance is absolutely essential. The body requires the right kind of nutrients in order to perform and develop correctly, and whether these come from food or from supplements, they are needed for many purposes. As a dietary supplement we recommend consuming 2g Magnesium Citrate (providing approximately 300mg of Magnesium), daily.

    Warnings: Magnesium Citrate can have a laxative affect, so you may need to alter our ‘Suggested Use’ to meet your personal needs. If you do experience these affects it is recommended that you reduce your dosage size.

Instant diarrhoea

I took a teaspoon of this a couple of times, trying with and without food. Each time I didn't have to wait long for strong stomach cramps followed by a couple of hours of my entire digestive system trying to exit me. I've noted that diarrhoea is a noted side effect of magnesium citrate and it may be that I'm particularly sensitive to this stuff, but it's one to watch out for.

Goes Well With:

Not with me.

not good

scoop is too big. there give 4 gram scoop for product that 2.5 gram/serving guessing the amount is hard. hard to dissolve in drinking water. both combination above give me a light diarrhea . (for me it's stronger laxative magnesium milk)

Works if you know the chemistry

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


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.

No taste, No mixabiliy

I have tried many magnesium citrates. They all tastes more or less the same just acidity level differs from 3-10 and mixability 8-10. “MyProtein Magnesium Citrate” absolutely different: It does not dissolve at all in water and has no taste- 0 acidity, despite its citrate form. This is very strange... I am disappointed and most probably stop using it for good.

I usually use capsules but decoded to try the powder. It doesn't mix at all, even with warm water. It's really grainy and it just sinks to the bottom of the glass. My Fiancé prefers supplements in powder and even he can't stomach it. Very disappointing purchase.

Not what I was expecting

Ok, I've made a big mistake here: I've bought this product without looking ath the reviews. After trying it once, I've looked a tthe reviews and relised the mistake! This powder doen't dissolve even using hot water just brewed, it doesn't taste like citrate and I suspect it may be just useless rather than dangerous! The Magnesium Citrate I was normally using dissolves quickly in warm water, making it "fizzy" as it does so, has the typical citrus taste and reacts with lemon juice and bicarbonate of soda. This doesn't, so I wonder what it really is!

Goes Well With:


Not magnesiumcitrate

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.

Vile taste

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 :)


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.
