MAGNESIUM CITRATE

Magnesium Citrate is a magnesium salt of citric acid widely used as a source of magnesium in dietary supplements and pharmaceuticals, and Magnesium Citrate is also used as a buffering and chelating ingredient in selected formulations.
Magnesium Citrate is commonly supplied as anhydrous Magnesium Citrate or as hydrated forms, and Magnesium Citrate is valued for relatively good bioavailability compared with some other magnesium salts.
Magnesium Citrate is widely used in oral products including effervescent powders, tablets, and solutions, but Magnesium Citrate can have a laxative effect at higher doses, so Magnesium Citrate use is typically guided by product labeling and applicable regulations.

Magnesium Citrate has a slightly acidic taste profile influenced by citrate.

Magnesium Citrate provides elemental magnesium and citrate ions when dissolved.
Magnesium Citrate is generally more water-soluble than some other magnesium salts.
Magnesium Citrate is often selected for relatively good bioavailability in oral supplementation.

Magnesium Citrate can act as an osmotic laxative by drawing water into the intestinal lumen.
Magnesium Citrate laxative effects are dose-dependent and can cause diarrhea if overused.
Magnesium Citrate should be used with appropriate directions, especially for short-term bowel-clearing use.

Magnesium Citrate can cause gastrointestinal discomfort in sensitive individuals at higher doses.
Magnesium Citrate use requires caution in people with kidney impairment due to magnesium accumulation risk.
Magnesium Citrate interactions with certain medications can occur, so spacing and guidance may be needed.

Magnesium Citrate stability depends on moisture control because powders can clump under humid storage.
Magnesium Citrate should be stored in tightly closed containers away from moisture and excessive heat.
Magnesium Citrate quality control commonly includes elemental magnesium assay and impurity limits.

Magnesium Citrate may be used in food or beverage fortification where permitted and properly formulated.
Magnesium Citrate can precipitate in some beverage systems depending on pH, ionic strength, and other minerals present.
Magnesium Citrate performance in liquids often requires formulation optimization to maintain clarity and stability.

Magnesium Citrate is widely used due to versatility, consumer familiarity, and practical solubility characteristics.
Magnesium Citrate product forms and specifications vary by supplier, affecting taste, flow, and dissolution rate.
Magnesium Citrate is valued as a flexible magnesium source for both nutrition and short-term digestive support.

Magnesium Citrate is typically supplied as a white to off-white powder or granules, and the hydration state of Magnesium Citrate can vary by supplier and grade.
Magnesium Citrate is formed by neutralizing citric acid with magnesium sources, producing a citrate salt that can complex magnesium ions and influence solubility behavior.
Magnesium Citrate is generally soluble to moderately soluble in water depending on form, particle size, and hydration state, and Magnesium Citrate can be formulated to dissolve effectively in effervescent systems.

Magnesium Citrate is widely used as a supplement because Magnesium Citrate is often considered to have good absorption compared with some less soluble magnesium salts.
Magnesium Citrate can produce an osmotic laxative effect at higher intakes, so product design and labeling must account for serving size and intended use.
Magnesium Citrate can interact with certain minerals and medications in the gastrointestinal tract, so formulation and consumer guidance should follow applicable requirements.
