Calcium L-Threonine Chelate

Calcium L-threonine chelate, also called calcium L-threoninate, is a chelate of calcium with the amino acid L-threonine, in which one calcium ion is bound to two threonine molecules (a 2:1 amino-acid-to-calcium salt). Nustras supplies it as a white powder, an amino-acid-chelated calcium source for the supplement sector.

Calcium L-threonine chelate is formulated into calcium and multimineral supplements in capsule, tablet and powder form, into amino-acid-chelate mineral premixes, into functional foods and beverages, and into sports and nutritional powders.

The material is a white to off-white, odourless fine powder, soluble in water. Calcium content, L-threonine content, loss on drying and pH are standardised to specification; calcium is determined by complexometric titration or ICP and threonine by HPLC, identity is confirmed by infrared spectroscopy, and heavy-metal and microbial limits are supplied to specification and confirmed on each lot's certificate of analysis. Molecular weight 276.30.

Nustras supplies calcium L-threonine chelate in bulk commercial quantities, in sealed food-grade bags and fibre drums, to manufacturers and formulators internationally, with a certificate of analysis, specification sheet and country-of-origin documentation on every lot. Amino-acid chelates of calcium are accepted mineral sources in major supplement markets; buyers confirm the elemental-calcium contribution, grade and permitted level for their application.
