Is tricalcium phosphate the same as calcium citrate?
No—tricalcium phosphate (E341iii) and tricalcium citrate (E333iii) are different calcium salts; citrate is more soluble and mainly used as a sequestrant/stabilizer and calcium fortificant, while phosphate is often an anti-caking agent and fortificant.

It’s used as a sequestrant and stabilizer to control acidity and bind metal ions, helping preserve color and texture, and it’s also used to fortify foods and supplements with calcium.
Which is better calcium citrate vs tricalcium phosphate?
For calcium supplementation/absorption, calcium citrate is often preferred because it’s more soluble and can be taken with or without food; tricalcium phosphate is less soluble but useful in foods as an anti-caking agent and when added phosphorus is desired.
