Frequently Asked Questions

Q1: What's the difference between Magnesium Glycinate 14% and 18%?

The 14%/18% difference reflects elemental Magnesium content measured via EDTA titration. 18% is the higher load, more efficient per-gram formulation; 14% is the standard buffered specification with better taste profile.

Q2: What is Magnesium Bisglycinate?

Magnesium Bisglycinate is a chelated form of magnesium where two glycine molecules are bound to one magnesium ion. It is considered one of the most bioavailable and gentle (non-laxative) forms of magnesium.

Q3: Can Magnesium Glycinate be combined with other ingredients?

Magnesium Glycinate is commonly combined with Vitamin B6 (P5P), Zinc, and L-Theanine in sleep and relaxation formulations. We recommend consulting with your formulation team.

Q4: What's the regulatory status in the EU?

Magnesium Bisglycinate is permitted as a food supplement ingredient in the EU. Specific regulatory status depends on intended application and labeling.

Q5: How is Magnesium content measured?

Magnesium content is quantified via EDTA complexometric titration per USP / Ph. Eur. methods.

Q6: What's the typical MOQ?

Standard MOQ is 25 kg. Smaller quantities (5-10 kg) are available for evaluation.

Q7: Do you offer custom specifications?

Yes. Custom specifications (e.g., specific Mg content, particle size, packaging) can be discussed with our coordination team.

Q8: What documentation is available?

Standard documentation includes COA, MSDS, allergen statement, Non-GMO statement. Additional documentation available upon request from production partners.
