Is TDS Good or Bad For Health? (Total Dissolved Solids)

Is TDS Good or Bad For Health?

If you’re like me, you have probably been wondering if TDS is Good or Bad for Health?

Did you know that the BIGGEST source of essential Calcium for your health is NOT Milk or Dairy, but WATER?

With the overdose of information (and mis-information) around this, and all the propaganda being served to you, in order to push the sale of RO Filters, I am sure you are as confused as I was in this regard. (See video at the end of this article)

What is TDS?Hardness Total Dissolved Solids

Total dissolved solids (TDS) is a measure of the dissolved combined content of all inorganic and organic substances contained in a liquid (namely water) in molecular, ionized or micro-granular suspended form.

More simply put – Total dissolved solids (TDS) are a measurement of the amount of dissolved ions in water. It is mainly comprised of inorganic salts (calcium, magnesium, potassium, sodium, bicarbonates, chlorides and sulphates), many of which are necessary life-sustaining nutrients. It may also contain lesser amounts of soluble organic matter. Water can carry impurities from natural and man-made sources.

By definition, the solids or salts constituting  TDS must be smaller than 2 micrometer.


PLEASE NOTE: TDS is a “secondary standard” of Water Quality; Secondary standards of water quality includes factors such as color and staining properties of water rather than potentially harmful health effects.


Basically the presence of minerals in water is must. The water we get in the form of bottled /packed water which is called purified, may or may not be good for our health.

Most brands of packaged water do not contain required quantum of minerals in it.

TDS levels are caused by the presence of Calcium, Potassium, Chlorides and Sodium, which are essential nutrients for your body.



Extremely high TDS may also be caused by certain poisonous chemicals like Lead, Arsenic, Cadmium, Nitrates etc.

However, if you live in such an area, it would be quite well-known locally (and the municipal corporation would be taking care of it) – it is not the kind of information that you would need to test for yourself.


How Do I Know If My Water Is Safe?

As a standalone measure, it is not adequate to ask – Is TDS Good or Bad For Health?

Water that is considered safe to drink is called potable water. It may either treated, cleaned, or filtered. It is compatible drinking water standards.

Potable water (or Drink-able water) is ideally free of harmful bacteria and contaminants and also considered safe to use in cooking and baking.

Water supposed to be potable or safe for drinking should meet following characteristics:-

  1. Be free of chlorine, fluoride, pharmaceutical drugs, metals (mercury, bromide, lead, and arsenic), chemicals, bacteria and more.
  2. It must have required quanta of Natural Minerals.
  3. It should be at neutral or slightly alkaline pH Balance.


How Much TDS Is Good or Bad for Health?

The standard in drinking water for TDS is 500 milligrams per litre (mg/l).

  • The Bureau of Indian Standards (BIS) fixes the upper limit of TDS in drinking water at 500 ppm.
  • The minimum TDS of water as prescribed should not be less than 30 milligram per litre.
  • For countries with healthy water sources (such as India), WHO has prescribed up to 1000 ppm as safe. [Read the WHO Report Here]. You can also Download the WHO report below.

The Reverse Osmosis Hoax

Mostly water purifier providers are in the habit of selling their products by misguiding the purchaser. They adopt methods of checking TDS water supply in a misleading format. [Also Read: The Reverse Osmosis Hoax]

They used electrolyser & put simultaneously in two pots, one containing water with low or negligible minerals & other with high minerals.

When they start electrolyser, after some prescribed time the water with high minerals becomes dirty & the water with minimum minerals remains unstained.  The purchaser thus is mis-led that the water they are drinking is health hazardous wherever it is fit to drink. The water which is unstained is prescribed as potable which is not true.

How To Treat Extremely High TDS

Again – while a Reverse Osmosis filter is ONE of the options of treating extremely high TDS (let’s say 600 and above, if you’re really paranoid about it), the treatment depends on TYPE of TDS.

The best option to deal with raised TDS depends on the specific ions present and their concentration.

Which means if the elevated TDS is due to calcium and magnesium, a water softener is a good option. The process may not reduce the TDS concentration, but it will manage problems linked with the ions.

If the problem is concerned with a raised concentration of nitrate, a reverse osmosis system or distillation unit can be installed.

The alternative for treating TDS in drinking water should only be determined after analysis of the particular ions contributing to the TDS measurement.
