Solgar is a well-regarded brand in the nutritional supplement space, and its chelated magnesium product is a popular choice for those looking to enhance their magnesium intake. The specific ingredients, from the active mineral forms to the inactive excipients, contribute to its quality and effectiveness. Understanding each component is crucial for informed supplement decisions.
The Active Magnesium Compounds
The primary ingredients delivering the mineral content in Solgar's chelated magnesium are a combination of two forms: magnesium bisglycinate chelate and magnesium oxide. This blend is strategic, combining a form known for high bioavailability with one that provides a high concentration of elemental magnesium.
Magnesium Bisglycinate Chelate
Magnesium bisglycinate chelate is a highly bioavailable and easily absorbed form of magnesium. In this form, magnesium is bound to two molecules of the amino acid glycine, a process known as chelation.
- High Bioavailability: The chelated structure protects the magnesium from binding with other compounds in the gut, ensuring a higher rate of absorption into the bloodstream.
- Gentle on Digestion: This form is less likely to cause digestive issues, such as the laxative effect sometimes associated with other magnesium types. Glycine is also a calming amino acid, which may contribute to the supplement's relaxation benefits.
Magnesium Oxide
Magnesium oxide is an inorganic magnesium salt commonly used in supplements.
- High Elemental Content: It is included to provide a higher concentration of elemental magnesium per tablet.
- Complementary Role: While less absorbable than its chelated counterpart, its inclusion allows for a higher total magnesium dosage in a more compact form.
The Other Ingredients (Excipients)
In addition to the active magnesium, the tablets contain several "other ingredients," or excipients, which help to form and stabilize the product. Solgar is known for using vegetable-derived excipients, making this product suitable for vegans.
Bulking and Binding Agents
- Microcrystalline Cellulose: A plant-derived material used as a bulking agent and binder. It helps to increase the tablet size, ensuring it's not too small to handle, and binds the ingredients together to maintain the tablet's shape.
- Vegetable Cellulose: This is typically a plant-based coating material that protects the tablet and can assist with its controlled release in the body.
Anti-Caking Agents
- Silica (Silicon Dioxide): A common anti-caking agent that prevents the powdered ingredients from clumping together during manufacturing and storage.
- Vegetable Magnesium Stearate: A lubricant derived from vegetable oils, it prevents the supplement ingredients from sticking to the manufacturing equipment during the tableting process.
Coloring and Glazing
- Titanium Dioxide (Color): Some formulations may include titanium dioxide to give the tablets a consistent white color.
- Vegetable Glycerin: Used as a glazing agent to provide a smooth, easy-to-swallow coating on the tablets.
What Does 'Chelated' Mean?
The term 'chelated' comes from the Greek word chele, meaning 'claw'. In the context of supplements, it means the mineral is bonded to an organic compound, often an amino acid, which 'claws' or holds onto the mineral. This process enhances mineral absorption in two key ways:
- Improved Stability: The chelated bond protects the mineral from reacting with other compounds in the digestive tract that could inhibit absorption.
- Different Absorption Pathway: The chelate allows the mineral to be absorbed through a different, more efficient pathway than non-chelated mineral salts.
For Solgar's chelated magnesium, this process involves bonding the mineral to glycine, resulting in a highly absorbable form that minimizes digestive discomfort.
Comparison of Magnesium Forms
To understand the advantage of Solgar's chelated magnesium, it's helpful to compare it with other common magnesium forms.
| Magnesium Form | Key Characteristic | Common Use | Bioavailability | 
|---|---|---|---|
| Magnesium Bisglycinate | Chelated with glycine, gentle on the stomach. | Relaxation, sleep support. | High | 
| Magnesium Oxide | High elemental content, but low absorption. | High concentration for boosting total magnesium. | Low | 
| Magnesium Citrate | Chelated with citric acid, can have a laxative effect. | Bowel regularity, sleep support. | High | 
| Magnesium Sulfate | Not a chelate; high laxative effect. | Epsom salt baths, saline laxatives. | Low Oral | 
Solgar's combination of bisglycinate chelate and magnesium oxide aims to provide both superior absorption from the chelate and a substantial dose of elemental magnesium from the oxide.
Dietary Considerations
Solgar emphasizes the purity and dietary suitability of its products. Its chelated magnesium is noted to be:
- Vegan/Vegetarian Friendly: All excipients are plant-derived.
- Free from Common Allergens: It does not contain gluten, wheat, dairy, soy, or yeast.
- Kosher Certified: The product also meets kosher dietary standards.
These considerations make the supplement accessible to a wide range of individuals with specific dietary needs or restrictions. Solgar offers detailed information on its formulas and product benefits on its official website.
Conclusion
The ingredients in Solgar chelated magnesium are a thoughtful combination of active and inactive components designed to maximize bioavailability and ensure product quality. The use of magnesium bisglycinate chelate and magnesium oxide provides a balanced approach to supplementation, offering both high absorption and a robust mineral dose. Furthermore, the inclusion of plant-based excipients makes it a suitable option for vegans and those with common dietary sensitivities. By understanding the function of each ingredient, consumers can feel confident in choosing a supplement that aligns with their health goals and dietary needs.
