Reverse osmosis is excellent at removing contaminants — but it is indiscriminate, also stripping out the beneficial minerals that give water its taste and balance. The result is “flat”, demineralized water.
The health and regulatory context
The WHO’s 2005 report Nutrients in Drinking Water cautioned against long-term consumption of demineralized water. Several markets now require minimum mineral levels — for example, India’s FSSAI mandates re-adding calcium and magnesium to packaged RO water.
Taste and consumer preference
Minerals shape mouthfeel and flavour. Remineralized water tastes better and supports a premium, naturally-mineralized positioning that consumers increasingly seek.
How to remineralize
A natural ionic mineral concentrate dosed into RO or purified water restores a balanced mineral profile and helps achieve target TDS and pH — without synthetic additives.
Coremin supplies natural ionic trace minerals from the Great Salt Lake as a B2B ingredient. Explore our Water Remineralization solutions, or contact our team for samples, certificates of analysis and bulk pricing.
