Understanding Elemental Magnesium
When evaluating a mineral supplement, a critical detail to look for is the amount of 'elemental' magnesium it provides. Elemental magnesium refers to the actual weight of the magnesium mineral itself, not the weight of the entire magnesium-containing compound, such as magnesium bisglycinate. This is because magnesium is a reactive metal and is always bound to another substance in supplements. For example, in magnesium bisglycinate, the magnesium is bound to the amino acid glycine. The body can only absorb and utilize the elemental portion of the compound. Therefore, comparing the elemental value is the most accurate way to assess a supplement's potency.
The Webber Naturals Formula
Webber Naturals offers a Magnesium Bisglycinate supplement that clearly lists its elemental content on the packaging. Each vegetarian capsule delivers 200 mg of elemental magnesium. It is important to note that Webber Naturals' formula is a buffered chelate, meaning it is a blend of magnesium bisglycinate and a small amount of magnesium oxide. According to product information found on retailers like Costco and Webber Naturals' own site, the 200 mg of elemental magnesium is sourced from both magnesium bisglycinate (approximately 76%) and magnesium oxide (approximately 24%). This proprietary, high-density blend is designed to be well-tolerated while providing a high amount of elemental magnesium.
Why Elemental Value and Form Matter for Absorption
For consumers, the elemental value combined with the form of magnesium has significant implications for absorption and side effects. Magnesium bisglycinate is highly valued for its superior bioavailability and gentleness on the digestive system. It is absorbed via different pathways than inorganic forms and is less likely to cause the laxative effect common with other supplements, such as magnesium oxide. The buffering with magnesium oxide in the Webber Naturals product increases the overall elemental content but can slightly alter the absorption characteristics compared to a pure, unbuffered form. However, the manufacturer states that their patented process maintains high tolerability.
Making an Informed Choice
When choosing a magnesium supplement, consider not only the amount of elemental magnesium but also the specific compound and your personal needs. For those seeking maximum absorption with minimal digestive upset, a chelated form like bisglycinate is an excellent option. Athletes or individuals with known deficiencies might require a higher dose, which necessitates careful label reading to determine the elemental value per serving. Always consult a healthcare professional before starting any new supplement regimen.
Comparison of Common Magnesium Supplements
To help illustrate the differences between various magnesium forms, here is a comparison table:
| Feature | Magnesium Bisglycinate | Magnesium Citrate | Magnesium Oxide |
|---|---|---|---|
| Elemental Content | Moderate (approx. 14-20% by weight) | Moderate (approx. 16% by weight) | High (approx. 60% by weight) |
| Bioavailability | Very High | High | Poor |
| Gentleness on Stomach | Excellent, very gentle | Can cause diarrhea at high doses | Poor, can cause digestive upset |
| Common Uses | Relaxation, sleep, muscle function | Constipation, general supplementation | Laxative, temporary relief |
Best Practices for Supplementation
To maximize the benefits of any magnesium supplement, including Webber Naturals magnesium bisglycinate, consider the following practices:
- Read the Label: Always check the supplement facts panel for the stated elemental magnesium content per serving. Do not rely solely on the headline claim, which may refer to the total compound weight.
- Split the Dose: For optimal absorption, it is often recommended to take smaller doses throughout the day rather than one large dose.
- Take with Food: Taking your magnesium supplement with a meal can further aid absorption and reduce any potential stomach upset.
- Combine with Other Nutrients: Magnesium works synergistically with other vitamins and minerals, such as Vitamin D and Calcium.
- Consult a Professional: A healthcare practitioner can help determine the appropriate dosage for your specific health needs and goals.
Conclusion
In conclusion, Webber Naturals magnesium bisglycinate offers 200 mg of elemental magnesium per capsule, derived from a buffered blend of magnesium bisglycinate and magnesium oxide. This formulation is designed for high absorption and is gentle on the digestive system, making it a popular choice for those seeking magnesium supplementation for muscle function, relaxation, and bone health. By focusing on the elemental value and understanding the specific formulation, consumers can make a well-informed decision about their health supplements.
