WE all know keeping hydrated is even more important when the sun is shining.

Getting enough liquid in your body means fewer headaches, more energy, lubricated joints, organ function and much, much more.

Collage of three different types of bottled and canned water. — We test three health waters

To get your two litres of water a day you just need to turn on the tap.

But there are now waters with health benefits.

Today I’ve put some to the test to see if they are worth the cost . . .

Alkaline water

ACTIPH Water from Shropshire undergoes a unique process of purification before having electrolytes magnesium sulphate, sodium bicarbonate and potassium bicarbonate added to it.

You are left with an alkaline water with a PH of 9+ compared to your average water, which is about 7.

Some studies suggest higher PH might help with hydration, acid reflux and bone health.

This water has a smooth, clean taste.

My favourite of the three.

I loved the 600ml bottle size, which is great to carry about.

£1.40 for 600ml, Tesco.

Is Bathroom Tap Water Safe to Drink?

Protein water

IN each 500ml bottle of Warrior Protein Water there is 10g of protein as well as essential vitamins, with zero sugar and only 48 calories.

It comes in two flavours, tropical and berry, and is a clever way to boost your protein intake if you don’t want to eat any actual food – plus you are obviously hydrating at the same time.

But this stuff is sweet. I tried the tropical flavour, which reminded me of Lilt.

Although it doesn’t contain sugar, it does contain plenty of sweetener.

So unless you’ve got a sweet tooth, this is not for you.

I thought the lid was great, unlike some other bottles where they can flick open.

I had this one in my sports bag and it didn’t spill.

From £1.67 for a 500ml bottle, Spar stores or teamwarrior.com.

Collagen water

TIDE has just launched a sparkling raspberry collagen water that can help support glowing skin, strong hair and healthier nails.

It is a premium collagen formula with 3.5g of high-quality, hydrolysed collagen peptides sourced from wild-caught North Atlantic and Pacific Ocean fish.

When you drink marine collagen, studies have shown it can hydrate and firm skin, reduce wrinkles, improve skin elasticity and enhance the overall structure and appearance of skin.

There are zero artificial sweeteners or additives but this one is very sweet thanks to the addition of fructose, a natural sugar that is found in fruit, vegetables and honey.

It comes in at just 27 calories per 250ml can.

If you’re drinking it for the collagen benefits I would recommend having two.

A clever idea for skin, but only if you have a sweet tooth.

From £27 for 12 cans or £2.25 each, wearetide.com.
