Calcium Citrate is a specific type of calcium supplement. It is a salt formed by combining calcium with citric acid, which makes it more bioavailable. Bioavailable means the substance is easier for your body to absorb and use compared to other forms.
It is primarily used to support bone health. Unlike some other calcium types, this form can be taken without food because it does not require stomach acid to be absorbed into the bloodstream.
To make this supplement, manufacturers combine calcium carbonate with citric acid in a controlled chemical reaction. This process creates a powder that is then measured and packed into capsules or pressed into tablets for sale.
This ingredient is generally affordable. The raw materials used to create it are common and the manufacturing process is straightforward, leading to high supply and plenty of competition between brands.

| Form | What it is | Why chosen | Does it actually differ? |
|---|---|---|---|

| Calcium Citrate | A specific form of calcium combined with citric acid. | It is better for people with low stomach acid, the elderly, or those taking acid-reducing medications because it is absorbed more easily than calcium carbonate. | Unlike calcium carbonate, calcium citrate helps people with low stomach acid maintain absorption and may help prevent the formation of calcium oxalate stones. |
Verdict: Calcium citrate is worth seeking out specifically if you are elderly, take acid-reducing medication, or have low stomach acid.
