PubMed indexes 8 records that name Calcium and Fosfomycin together, either in the title or in an interaction, co-administration, or pharmacokinetic context. The key findings come first, in the authors’ own words, followed by every study with its design and PubMed link.
A summary of published research, not medical advice. A pharmacist can check any combination against your full list of medicines and supplements.
Reviews and human studies first. Each quote is the authors’ own conclusion about their study, not a NutriStack assessment, and a single study is not a consensus.
“This study provides relevant information on the pharmacokinetic profile of fosfomycin in women after oral administration as calcium salt. This population model may be very useful for establishing dosage recommendations of fosfomycin calcium to treat urinary tract infections in women.”
“In the over 60 years of age group, the corresponding microbiological outcome and clinical outcome rates evaluated for cure were 90.9 and 100%, respectively, and those evaluated for recurrence were 50.0 and 60.0%, respectively. These results indicate the usefulness of fosfomycin calcium administered at 1 g three times daily for 2 days for acute uncomplicated cystitis.”
“Pharmacokinetic elimination of the two forms of fosfomycin was only moderately affected in elderly subjects; we observed lower urinary elimination, about 58 versus 28% of the dose in 24-h urines for the tromethamine salt and decreased renal clearance of both forms. However, the dosages of tromethamine and calcium fosfomycin need not be adjusted for elderly subjects who have endogenous creatinine clearances above…”
Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.

Names both Calcium and Fosfomycin in its title.
“The amount of antibiotic ingested in trial I was three times more than in trial 2. These results suggest that calcium fosfomycin is best used in the drinking water for the treatment of colibacillosis.”
Names both Calcium and Fosfomycin in its title.
“Pharmacokinetic elimination of the two forms of fosfomycin was only moderately affected in elderly subjects; we observed lower urinary elimination, about 58 versus 28% of the dose in 24-h urines for the tromethamine salt and decreased renal clearance of both forms. However, the dosages of tromethamine and calcium fosfomycin need not be adjusted for elderly subjects who have endogenous creatinine clearances above 50 ml/min per 1.73 m2.”
Names both Calcium and Fosfomycin in its title.
“coli reported by EUCAST. Our results show that oral calcium fosfomycin at a dose level of 1000 mg every 8 h provides urine concentrations sufficient to ensure efficacy for the treatment of UTIs in women.”

Search-based evidence indexes have real limits, and it is worth being explicit about them:
NutriStack is a free iPhone app for organising a supplement routine: what you take, when, and what the published record says about it. Its exploratory interaction checker covers Calcium, Fosfomycin, and several hundred other substances.
Log your routine, get reminders at the times you choose, and scan a label to add a product. The checker is a research and organisation tool, not a clinical decision aid.
