Understanding the elemental magnesium in MG Plus Protein
Many consumers are confused by supplement labels that list a total compound weight versus the actual elemental mineral amount. For a product like MG Plus Protein, it's crucial to understand the exact dose you're receiving. Each tablet of MG Plus Protein is formulated to provide 133 mg of elemental magnesium. This is the actual amount of the mineral magnesium your body can use, not the weight of the entire compound it's bound to.
The magnesium in this supplement comes from a magnesium oxide amino acid chelate. This chelated form means the magnesium is bound to an amino acid, which helps facilitate its absorption in the digestive system. While other compounds like magnesium oxide have a higher percentage of elemental magnesium by weight, they are often poorly absorbed by the body. The chelated formula in MG Plus Protein is designed to overcome this bioavailability issue, ensuring a more effective delivery of the mineral.
The misleading protein component
The product's name, 'MG Plus Protein,' can be confusing. It's important to clarify that the protein content in each tablet is minimal—only 26 mg of soy protein. This small amount is used in the chelation process and does not serve as a dietary protein supplement. The main benefit and purpose of this product is its magnesium delivery, not its protein content.
Why elemental magnesium matters
When comparing different magnesium supplements, always look at the elemental magnesium value, which represents the actual, usable mineral quantity. Here's how to read a supplement label like a pro:
- Find the main ingredient: On the
Supplement Factspanel, locate the entry for 'Magnesium'. - Identify the value: The number listed next to 'Magnesium' in milligrams (mg) is the elemental amount. The label may also mention the compound in parentheses, for example, 'Magnesium (as magnesium amino acid chelate)'.
- Compare bioavailability: The form of magnesium (chelate, citrate, oxide, etc.) is as important as the amount. High bioavailability, meaning better absorption, is key to receiving the supplement's full benefits.
Comparison of elemental magnesium bioavailability
To illustrate the importance of bioavailability, here is a comparison of different magnesium forms. This helps explain why a supplement with a lower percentage of elemental magnesium (by total compound weight) can be more effective than one with a higher percentage, if its absorption rate is superior.
| Type of Magnesium | Total Compound Weight | Bioavailability | Elemental Magnesium Percentage | Notes |
|---|---|---|---|---|
| Magnesium Oxide | 1000 mg | Low (approx. 4%) | ~60% | High elemental percentage, but poor absorption makes it less effective for systemic needs. Common in laxatives. |
| MG Plus Protein (Chelate) | ~159 mg | High | 133mg/tablet | Delivers a significant, absorbable amount of elemental magnesium due to its chelated form. |
| Magnesium Glycinate | 1000 mg | High (approx. 80%) | ~14% | Lower elemental percentage but very high absorption rate. Often used for relaxation and sleep. |
| Magnesium Citrate | 1000 mg | Moderate to High | ~15% | Well-absorbed and known for its mild laxative effect, making it useful for regularity. |
The broader context of magnesium supplementation
Beyond the specific amount in MG Plus Protein, it's beneficial to understand why adequate magnesium intake is important. Magnesium is involved in over 300 biochemical reactions, playing roles in nerve function, muscle contraction, blood glucose regulation, and energy production. Factors like stress and certain diets can increase your body's need for this vital mineral. Always consult a healthcare professional before starting any new supplement regimen, especially if you have pre-existing conditions.
Conclusion
In summary, each tablet of MG Plus Protein provides 133 mg of elemental magnesium from a bioavailable chelated form. Despite its name, the product's primary function is to deliver this mineral, not to act as a significant source of protein. By understanding the difference between elemental magnesium and total compound weight, you can make more informed choices about your supplementation and ensure you are meeting your daily nutritional requirements effectively.
