Sorting Out the Magnesium Supplements That Are Right for You

Introduction

When it comes to magnesium supplementation, there are a few things to consider. Magnesium is an essential mineral that plays a key role in many bodily functions, such as metabolism, muscle and nerve function, and bone health. When selecting a magnesium supplement, it's important to understand the various forms of magnesium available and the pros and cons of each. This article will provide guidance on how to choose the right magnesium supplement for your needs.

Types of Magnesium Supplements

There are numerous forms of magnesium supplements available on the market. The most common forms used in supplements are magnesium oxide, magnesium citrate, magnesium chloride, and magnesium glycinate.

Magnesium oxide is the most inexpensive form of magnesium supplement, but it has a low bioavailability, meaning it is not easily absorbed by the body. It is, however, a good choice for those needing to quickly replenish their magnesium stores.

Magnesium citrate is the most bioavailable form of magnesium supplement, meaning it is easily absorbed by the body. It is also the most popular form of magnesium supplement. However, it is more expensive than magnesium oxide.

Magnesium chloride is a good choice for those needing to replenish magnesium stores quickly. It is also more bioavailable than magnesium oxide, but less bioavailable than magnesium citrate.

Magnesium glycinate is the best form of magnesium supplement for those looking to maximize absorption and increase their magnesium stores over time. It is the most expensive form of magnesium supplement and also the most bioavailable.

What to Look for in a Magnesium Supplement

When selecting a magnesium supplement, it's important to look for one that has been tested for purity and contains no added fillers or artificial ingredients. Additionally, look for a supplement that has been verified by a third-party lab for accuracy and potency. The supplement should also include a breakdown of the different forms of magnesium it contains and the amount of each form.

The daily recommended dosage of magnesium varies, depending on age and gender. Most adults should aim to get between 310 to 420 milligrams of magnesium per day. It is important to consult with a healthcare professional before starting any new supplement regimen to ensure you are taking the right dosage for your needs.

Conclusion

Choosing the right magnesium supplement for your needs can be tricky. Taking into account the various forms of magnesium and their bioavailability, as well as the recommended dosage and purity of the supplement, can help ensure you are selecting the best supplement for your needs. Be sure to consult with a healthcare professional before starting any new supplement regimen.
