Elevated levels of TDS is not an Indicator of what may be in the water, only what the total aggregate is. Here in Colorado, USA I have a Customer who has a TDS of only 191 mg/L, but has High levels of Arsenic and Uranium. It would be best to determine what is making up your TDS if it is suspected harmful elemental contaminants could be present.

I have had a POU RO system for several years on 200 mg/L TDS, producing 8 mg/L TDS. The water has a crisp after taste. The US EPA Secondary Standards Recommends water with a TDS over 500 mg/L should be on Reverse Osmosis or avoid consumption. Higher levels of TDS tend to leave a bitter or salty taste to water. Remember the TDS stands for Total Dissolved Solids which is organic and inorganic molecules, and are primarily insoluble mineral and metallic salts. Research has indicated high purity water such as RO or Distilled water rehydrates the bodies cells faster than water with higher levels of dissolved solids can.
