About Our Dataset

This analysis is based on a comprehensive dataset of 250 distinct magnesium-containing supplements available on the market. Our team regularly updates this dataset to ensure the information is current and accurately reflects industry trends. The statistics, averages, and percentages in this article are derived exclusively from this product list, providing a precise snapshot as of our latest update. Of the 250 products reviewed, 198 were identified as specific magnesium supplements or multivitamins with a significant magnesium component, and these form the core of our analysis.

Ingredient Deep Dive: The Most Common Magnesium Forms

Magnesium is always bound to another molecule to form a stable compound, and the type of molecule affects its absorption and use in the body. Our analysis of 198 products revealed a clear hierarchy of popular forms.

Magnesium citrate is the most frequently used form, appearing in 31% of the supplements we analyzed. It's known for its good bioavailability and is often used to support regular bowel movements. Following closely is magnesium oxide, found in 27% of products. While it contains a high concentration of elemental magnesium, its bioavailability is generally considered lower than other forms. Magnesium glycinate (or bisglycinate), a form chelated with the amino acid glycine, is present in 17% of supplements and is often chosen for its calming properties and high absorption without a laxative effect.

Product Format: Capsules Dominate the Market

When it comes to how consumers take their magnesium, manufacturers show a clear preference for encapsulation. Based on our data, capsules (including veggie caps and softgels) represent a commanding 45% of the market. This format is popular for its convenience and ability to mask the taste of ingredients.

Tablets are the second most common delivery system, making up 34% of the products analyzed. They are often more cost-effective to produce and can hold a higher dose in a smaller size. Powders and liquids, which offer flexible dosing and may be easier for individuals who dislike swallowing pills, account for a combined 18% of the market. Other formats like gummies or single-serving packs are far less common, representing the remaining 3%.

Dosage Analysis: A Look at Magnesium Per Serving

The amount of elemental magnesium per serving varies dramatically across products. The average dosage in our dataset is 330 mg. However, the median dosage is slightly higher at 350 mg, indicating that the majority of products cluster around this amount.

The most common dose offered is 400 mg per serving, which aligns with the higher end of daily recommendations for adults. The range is incredibly wide, starting from a low of just 5 mg in some complex formulas to a high of 800 mg in a potent, standalone supplement. This vast range underscores the importance of reading labels carefully to match a product's dosage with your specific health needs.

Common Pairings: What Else is in Magnesium Supplements?

Magnesium is rarely the only ingredient in a supplement bottle. Manufacturers often include other vitamins and minerals to enhance absorption or provide synergistic effects. Our analysis revealed a few key partners that appear frequently.

Zinc is the most common co-ingredient, found in 29% of the magnesium-containing products we reviewed. This pairing is popular in formulas aimed at immune support and hormonal health. Calcium is the second most frequent companion, present in 23% of supplements, often in products targeting bone health. Vitamin D3 (17%) and Vitamin B6 (16%) are also very common, as both are believed to play a role in magnesium's absorption and utilization within the body. A less common but notable pairing is L-Theanine (3%), typically found in formulas designed for relaxation and sleep support.

Summary of Key Statistics

Our analysis of 250 magnesium supplements provides a clear, data-backed picture of the market. Here are the key takeaways:

• Most Common Form: Magnesium Citrate is the most frequently included form, appearing in 31% of analyzed products.
• Dominant Format: Capsules are the market leader, accounting for 45% of all magnesium supplements.
• Typical Dose: The average serving contains 330 mg of elemental magnesium, with 400 mg being the most common dosage.
• Top Pairings: Zinc (29%), Calcium (23%), and Vitamin D3 (17%) are the ingredients most often formulated alongside magnesium.
• Pricing Insights: The median cost per serving is $0.45. Evaluating the cost per 100 mg of elemental magnesium is the best way to compare the true value between different products.
