  • 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

    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 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.

    The dietary choices of all our customers are extremely important to us. Whilst this product is manufactured using ingredients and processing aids suitable for the vegan diet, please note that dairy powders are also used within the same production facility and cross contamination may occur at very small levels.

    Please note that the labelling on this product is provided in English as a minimum. French, Italian, German, Spanish, Danish, Swedish and Finnish may also be present on a product by product basis.

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

Dear God...

Instead of saying it may cause laxative effects just say it DOES. After 1/2 hr to 45mins if taking it the toilet is your best friend. No bueno

The good Magnesium

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

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.
Goes Well With:
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!
