Popular questions
Does calcium citrate cause constipation?
At the small amounts used in foods (E333), it’s unlikely to cause constipation; at supplement doses, some people may experience it, but calcium citrate is generally less constipating than calcium carbonate.
Which is better for osteoporosis calcium citrate or carbonate?
Both can help if total calcium and vitamin D intake are adequate; calcium citrate is better absorbed (especially with low stomach acid) and gentler on the gut, while carbonate has more elemental calcium per tablet, costs less, but is more likely to cause constipation and should be taken with food.
Is calcium citrate the same as calcium?
No—calcium citrate is the calcium salt of citric acid (E333) that supplies calcium; “calcium” refers to the elemental mineral itself.
What is the difference between calcium and calcium citrate?
Calcium is the elemental nutrient, whereas calcium citrate is a compound that delivers calcium bound to citrate (about 21–24% calcium by weight) and is used as a food additive (E333) and in supplements; the citrate form is more soluble and well absorbed.
Can calcium citrate cause constipation?
At food-use levels it’s unlikely; at supplement doses it can in some people, though it tends to cause less constipation than calcium carbonate.
What is the refractive index of ktpp?
There isn’t a single published refractive index for solid pentapotassium triphosphate; food-grade specs don’t list it. For aqueous solutions, refractive index depends on concentration and temperature, so you’d need to measure nD under your specific conditions.
What is the refractive index of potassium triphosphate?
A fixed refractive index isn’t typically reported for the solid; it’s not a standard QC parameter for this additive. In solution, the refractive index increases with concentration and varies with temperature and wavelength, so measure it for your formulation.
What is the refractive index of potassium tripolyphosphate?
No standard single value is published for the solid; specifications for E451ii don’t include refractive index. For practical purposes, determine nD on your specific potassium tripolyphosphate solution at the required concentration and temperature.
