Thank you for reaching out to us!

Our website does list an interaction between coconut water and ciprofloxacin, so it's important to be careful here.

Coconut water contains some calcium, which can interact with ciprofloxacin. This is why your ciprofloxacin prescription bottle may have a sticker advising against combining it with calcium-containing products (due to the interaction with calcium-containing products).

Calcium can chelate, or bind, to some antibiotics, including ciprofloxacin, reducing its absorption. To be safe, it is generally recommended to separate the administration of ciprofloxacin and calcium by at least a few hours.

It is important to note that the calcium content of coconut water can vary greatly between products. Analysis of coconut water shows that the calcium content can range from about 100mg to 300mg per 1,000 mL (1 liter). Therefore, the severity of this interaction depends on how much coconut water you consume with ciprofloxacin.

A small sip or two is likely safe to combine with ciprofloxacin without any major impact on the absorption of the antibiotic. However, consuming large amounts of coconut water might provide enough calcium to reduce absorption.
