How to Say "calcium" in Spanish
The Spanish word for “calcium” is “calcio” — B1 level.

Examples

It's a Masculine Noun
Even though it doesn't refer to a person, 'calcio' is masculine. You should always use 'el' or 'un' with it: 'el calcio'.
Linking with 'de'
To describe something related to calcium (like a pill or a deficiency), Spanish uses the word 'de' (of) to connect the words. For example: 'pastilla de calcio' (calcium pill).
The 'Soccer' Confusion
Mistake: “Using 'calcio' to mean the sport of soccer.”
Correction: In Spanish, 'calcio' is only the mineral. If you want to talk about soccer, use the word 'fútbol'. (Note: 'Calcio' does mean soccer in Italian, which is why some learners get confused!)
