Calcium Bisglycinate
Calcium glycinate/bisglycinate is a chelated calcium source recognized as a permitted nutrient source by EFSA and used in food fortification. Calcium intake supports bone health; excessive intake (above the UL of 2,500 mg/day for adults) is associated with kidney stones and possible cardiovascular concerns.
What it is
Calcium chelated with two glycine molecules (calcium bisglycinate), a chelated mineral supplement form.
Calcium fortificant in foods, beverages, and supplements.
Why it's flagged
- Excess intake → hypercalcemia, kidney stones
- May reduce iron/zinc absorption
What regulators actually say
"The Tolerable Upper Intake Level for calcium for adults is 2,500 mg/day, falling to 2,000 mg/day for those over 50."
"The Panel concludes that the use of calcium bisglycinate as a source of calcium ... is not of safety concern."
Regulatory status
United States — FDA
Calcium salts of amino acids generally permitted as nutrient sources/dietary supplements; broader calcium fortification at 21 CFR 184.1191 (calcium glycerophosphate) and related sections.
European Union — EFSA
Calcium bisglycinate authorized as a source of calcium for foods (EFSA opinion 2014).
