Magnesium citrate is widely available over-the-counter at various retailers. You can typically find it at:
* Pharmacies: Stores like CVS, Walgreens, Rite Aid, and independent local pharmacies carry magnesium citrate products.
* Supermarkets and Grocery Stores: Many major grocery chains, including Walmart, Target, Kroger, and Safeway, stock magnesium citrate in their health and wellness aisles.

When purchasing, magnesium citrate is commonly found in liquid form, often as a laxative, or as capsules or tablets for magnesium supplementation.
What types of magnesium citrate are there?
Magnesium citrate is available in several forms to suit different needs and preferences. The most common forms include:
* Liquid Solutions: These are frequently used as a bowel prep or for occasional constipation relief. They are typically a clear or slightly colored liquid.
* Capsules and Tablets: For daily magnesium supplementation, magnesium citrate is often found in capsule or tablet form. These are easier to swallow for some individuals.
* Powders: Some products come as powders that can be mixed with water or other beverages.
Each form delivers magnesium citrate, but the absorption rate and intended use might differ slightly.
How does magnesium citrate work as a laxative?
Magnesium citrate acts as an osmotic laxative. When ingested, the magnesium ions draw water into the intestines [1]. This increased water content softens the stool and stimulates bowel movement by increasing the volume of the stool and promoting muscle contractions in the colon [1]. It is generally effective for relieving occasional constipation.
How quickly does magnesium citrate start working?
The onset of action for magnesium citrate as a laxative is typically between 30 minutes and 6 hours after ingestion [1]. The exact timing can vary depending on the individual, the dosage taken, and whether it was consumed with or without food.
Are there any side effects of magnesium citrate?
Common side effects associated with magnesium citrate, particularly when used as a laxative, can include abdominal cramping, bloating, gas, and diarrhea [1]. More serious side effects are rare but can occur, especially with overuse or in individuals with kidney problems. These might include nausea, vomiting, dizziness, and irregular heartbeat [1]. It is important to follow dosage instructions and consult a healthcare professional if experiencing severe or persistent side effects.
Who should not take magnesium citrate?
Individuals with certain medical conditions should exercise caution or avoid magnesium citrate. This includes people with kidney disease, as their bodies may not effectively clear excess magnesium, leading to magnesium toxicity [1]. Those with bowel obstructions, severe abdominal pain, nausea, or vomiting should also avoid magnesium citrate unless directed by a healthcare provider [1]. Pregnant or breastfeeding individuals should consult their doctor before use.
Where can I buy magnesium supplements in general?
Beyond magnesium citrate, other forms of magnesium supplements are available at similar retail locations. You can find magnesium oxide, magnesium glycinate, magnesium L-threonate, and others at pharmacies, supermarkets, health food stores, and online retailers. These different forms are often chosen based on their bioavailability and specific health benefits, such as muscle relaxation, nerve function, or cognitive support.
