    Applications of Magnesium Potassium Citrate

    Dr. Paul Lohmann® supplies Magnesium Potassium Citrate for specialized B2B applications in the food, beverage and nutritional supplement industries.

    Nutritional Supplement Applications

    In nutritional supplements, Magnesium Potassium Citrate is used as a combined source of magnesium and potassium. As both minerals are present in one compound, it enables manufacturers to incorporate two essential minerals into a single raw material.

    Magnesium Potassium Citrate can be used in powder sachets, stick packs, capsules, tablets, and multi-mineral formulations. Its good water solubility also makes it suitable for products that are intended to be dissolved or dispersed before consumption.

    Typical applications include:

    • Powdered nutritional supplements
    • Multi-mineral formulations
    • Effervescent and instant products
    • Products supporting the daily intake of magnesium and potassium

    The required quantity of Magnesium Potassium Citrate depends on the specified mineral content and the intended magnesium and potassium dosage of the finished product.

    Food and Beverage Applications

    Magnesium Potassium Citrate is suitable for the mineral enrichment of foods and beverages. Its good water solubility, neutral taste and neutral pH are particularly advantageous in formulations where a strong salty, bitter or acidic taste is undesirable.

    The product may be incorporated into beverage powders, liquid products and fortified foods. Because it supplies both magnesium and potassium, it can simplify mineral premixes and reduce the number of individual mineral compounds required in a formulation.

    Applications include:

    • Mineral-fortified beverages
    • Beverage powders and instant drinks
    • Functional foods
    • Fortified food products
    • Powdered food and drink preparations
    • Salt replacement

    The suitability of the product for a particular food or beverage formulation should be confirmed through application-specific testing, especially with regard to taste, stability, solubility and compatibility with other ingredients.

    Sports Nutrition and Electrolyte Formulations

    Magnesium Potassium Citrate is also used in sports nutrition and electrolyte-oriented product concepts. Magnesium and potassium both contribute to normal muscle function, while magnesium contributes to electrolyte balance and normal energy-yielding metabolism. Potassium additionally contributes to the normal functioning of the nervous system.

    These nutritional functions make Magnesium Potassium Citrate a suitable mineral source for products aimed at physically active and health-conscious consumers. It can be used in mineral powders, tablets, capsules and beverage formulations intended to supplement the daily intake of magnesium and potassium.

    Magnesium Potassium Citrate in sports nutrition applications:

    • is used as a combined magnesium and potassium source.
    • can be incorporated into mineral and electrolyte formulations.
    • is suitable for soluble powders and beverage concepts due to its good water solubility.
    • can be combined with vitamins, carbohydrates, amino acids or additional minerals.

    Health claims relate to magnesium and potassium as nutrients and may only be used when the finished product meets the applicable legal conditions of use.
