(ii) at least one source of potassium; and (iii) at least one source of citrate; wherein the composition has a bulk density of 0.35-0.75 g/cm3 and comprises from about 8% to about 15% (wt/wt) magnesium and from about 7.5% to about 16% (wt/wt) potassium and 75% to 80% citrate on dry weight basis and having pH of about 7.5-10.5. ### Claim 2 (depends on 1) The composition according to claim 1, comprising 9% to 13% (wt/wt) magnesium and about 8% to 12% (wt/wt) potassium on a dry basis, having a bulk density of 0.55 to 0.65 g/cm3. ### Claim 3 (depends on 1) The composition according to claim 1, wherein the magnesium source is selected from the group consisting of magnesium hydroxide, magnesium oxide, magnesium carbonate, magnesium citrate, and any mixture thereof. ### Claim 4 (depends on 1) The composition according to claim 1, wherein the citrate source is selected from the group consisting of citric acid, citric acid anhydrous, citric acid monohydrate, citric acid mono-, di- or tri-sodium salt, citric acid tripotassium salt, and ammonium citrate. ### Claim 5 (depends on 1) The composition according to claim 1, wherein the source of potassium is selected from the group consisting of potassium hydroxide, potassium citrate, potassium bicarbonate, and any mixture thereof. ### Claim 6 (depends on 1) The composition according to claim 1, wherein the potassium source is potassium hydroxide or potassium oxide; the magnesium is magnesium oxide or magnesium hydroxide; and the citrate is citric acid anhydrous or monohydrate. ### Claim 7 (depends on 6) The composition according to claim 6, comprising a molar ratio of magnesium:potassium:citrate of 1:1:1. ### Claim 8 (depends on 6) The composition according to claim 6, comprising a molar ratio of magnesium:potassium:citrate of 5:2:4. ### Claim 9 (depends on 1) The composition according to claim 1, further comprising stabilizers, coloring agents or emulsifiers. ### Claim 10 (depends on 1) The composition according to claim 1, in a dry form selected from the group consisting of powder, granules, and flakes. ### Claim 11 (depends on 1) The composition according to claim 1, dissolved or suspended in an aqueous based solution. ### Claim 12 (depends on 1) A food or nutritional product comprising a composition according to claim 1. ### Claim 13 (depends on 12) The product according to claim 12, being a beverage. ### Claim 14 (depends on 13) The product according to claim 13, wherein the beverage is a natural based beverage or a non-natural based beverage. ### Claim 15 (depends on 14) The product according to claim 14, wherein the natural based beverage is a fruit or vegetable based beverage or a milk based beverage. ### Claim 16 (depends on 15) The product according to claim 15, wherein the milk based beverage is selected from the group consisting of a soy milk beverage, reconstituted milk formula beverage, goat milk beverage, sheep milk beverage, camel milk beverage, substitute milk beverage, cow milk beverage, oat milk beverage, human milk beverage, and any mixture thereof. ### Claim 17 (depends on 14) The product according to claim 14, further comprising one or more of a flavoring, vitamin, mineral, and protein. ### Claim 18 (depends on 14) The product according to claim 14, comprising at least 2 g/L to 6 g/L of the magnesium rich composition. ### Claim 19 (depends on 14) The product according to claim 14, being stable for a period of at least 90 days. ### Claim 20 A method for producing a dried magnesium-rich composition, having a bulk density of 0.35-0.75 g/cm3 and a pH of about 7.5-10.5 comprising: (i) dissolving at least one source of citrate in water, agitating and cooling to produce an agitated cooled aqueous solution; (ii) adding at least one source of magnesium and at least one source of potassium to the agitated cooled aqueous solution to produce an aqueous magnesium solution; and (ii) drying the aqueous magnesium solution to produce the dried magnesium-rich composition, wherein the composition comprises at least 8% magnesium on a dry weight basis, and at least 7.5% potassium on a dry weight basis. ### Claim 21 (depends on 1) The composition of claim 1, being suitable for fortifying a protein-containing food or beverage. ### Claim 22 (depends on 1) The composition of claim 1, being suitable for preparing a stable protein-containing food or beverage. ### Claim 23 (depends on 21) A method for fortifying a food or beverage which comprises adding the composition of claim 21 to a food or beverage.
