Description

Non-Buffered Magnesium Bisglycinate Powder

Magnesium bisglycinate is a chelated mineral formed by bonding magnesium with two molecules of the amino acid glycine. This chelation process creates a stable, neutral complex that protects magnesium from interfering with other minerals in the digestive tract, resulting in superior absorption. Research indicates that this form has higher bioavailability compared to inorganic magnesium salts such as magnesium oxide or citrate.

🧪 "Non-Buffered" – The Pure Form: The term "non-buffered" is critical. Many commercial magnesium bisglycinate products are buffered-meaning they are diluted with magnesium oxide to increase the total magnesium content per gram while reducing manufacturing costs. Our non-buffered magnesium bisglycinate contains no magnesium oxide or other fillers. It is the pure chelate, delivering a consistent 14.1% elemental magnesium by mass.

Why Choose Non-Buffered? Because you get exactly what you pay for: a high-purity, fully reacted amino acid chelate with predictable solubility and performance. The buffered versions may contain up to 40-50% magnesium oxide, which significantly alters the dissolution profile and bioavailability.

Production & Purity: Our non-buffered magnesium bisglycinate is produced via a controlled reaction between high-purity glycine and a magnesium source. This ensures a complete chelation reaction without residual free magnesium oxide or unreacted glycine. The product meets rigorous international standards for amino acid chelates.

Benefits of Non-Buffered Magnesium Bisglycinate Powder

01Superior Bioavailability

As a chelated mineral, magnesium bisglycinate is absorbed via the amino acid transport pathway, bypassing competition from other minerals. Significantly higher bioavailability compared to inorganic magnesium salts.

02Gentle on Digestion

The chelated form is non-ionic and does not draw water into the intestinal lumen. Exceptionally well-tolerated - no laxative effect commonly associated with magnesium citrate or oxide.

03Pure Formulation Advantage

No hidden magnesium oxide fillers. Consistent, high-purity ingredient for clean-label products with predictable solubility and performance.

04Neutral pH

Unlike many magnesium salts, the bisglycinate chelate is pH‑neutral in solution. Suitable for delicate formulations and liquid applications.

05Supports Sleep, Stress & Muscle Health

Magnesium is essential for over 300 enzymatic reactions. Plays a critical role in muscle relaxation, nervous system regulation, and energy production.

06High Chelation Degree

≥90% chelation degree verifies the completeness of the chelation reaction - minimal free magnesium oxide and unreacted glycine.

Application Fields

Dietary Supplements (Hero Application): Capsules & tablets (200–400 mg elemental Mg), powdered drink mixes, gummies & chewables, multimineral blends.
Clinical Nutrition: Liquid supplements (excellent solubility), medical foods for malabsorption conditions.

FAQ

Q1: What is the difference between "buffered" and "non-buffered" magnesium bisglycinate?

A: "Buffered" magnesium bisglycinate contains added magnesium oxide to increase the total magnesium percentage per gram. This is a common industrial practice to lower production costs. Non-buffered magnesium bisglycinate is the pure, full-reaction chelate without any fillers. It contains approximately 14.1% elemental magnesium by mass and offers superior purity, predictable solubility, and a cleaner label.

Q2: Why is non-buffered magnesium bisglycinate better?

A: It provides a consistent, high-purity ingredient. The buffered versions can alter the dissolution profile, may cause digestive upset due to the magnesium oxide content, and make precise dosing more difficult. For premium formulations, non-buffered is the preferred choice.

Q3: What is the elemental magnesium content?

A: The theoretical elemental magnesium content is approximately 14.1% by mass. Our product typically assays between 14.0% and 14.5%.

Q4: Is this form of magnesium well absorbed?

A: Yes. Magnesium bisglycinate is a chelated mineral, meaning it is bound to two glycine molecules. This allows it to be absorbed via the amino acid transport pathway, bypassing competition from other minerals. It has higher bioavailability compared to inorganic salts like magnesium oxide or magnesium citrate.

Q5: Does it cause a laxative effect?

A: No. Unlike magnesium citrate or magnesium oxide, the chelated form is non-ionic. It does not draw water into the intestinal lumen, making it exceptionally gentle on the digestive system. This is one of the primary reasons it is used for sleep and stress support.

Q6: Is Non-Buffered Magnesium Bisglycinate vegan?

A: Yes. Our magnesium bisglycinate is produced via chemical synthesis from non-animal sources. It does not contain any animal-derived components.

Q7: What is the shelf life?

A: 24 months in original sealed container under cool, dry conditions (≤25°C, ≤60% RH). Once opened, use within 12 months.

Q8: What is the recommended daily dosage?

A: Typical supplemental doses range from 200 mg to 400 mg of elemental magnesium per day. For magnesium bisglycinate powder, this corresponds to approximately 1,400 mg to 2,800 mg of the chelate (based on 14.1% elemental magnesium). Always consult a healthcare provider for personalized recommendations.

Q9: Can Non-Buffered Magnesium Bisglycinate be used in clear liquid supplements?

A: Yes. It is readily soluble in water, making it an excellent choice for liquid formulations, ready-to-drink beverages, and powder mixes.

Q10: Is it stable in solution?

A: Yes, aqueous solutions are stable at neutral pH. However, like all amino acid chelates, solutions should be protected from heat and prolonged exposure to light. For best results, formulate in a pH-neutral environment and use appropriate preservatives.

Q11: Can Non-Buffered Magnesium Bisglycinate be used with other minerals?

A: Yes - it can be formulated with zinc, calcium, copper, and other minerals. However, as with all minerals, separation of doses is recommended when high doses of competing minerals are used.

Q12: Is Non-Buffered Magnesium Bisglycinate suitable for gummies?

A: Yes - with proper formulation. Its neutral taste and high solubility make it an excellent choice for gummies and chewable supplements.
