Are stainless steel water bottles safe to drink from?

In recent years, stainless steel bottles have become the water bottle of choice for many consumers. Not only are they one of the safer and healthier water bottle choices but their environmental, social and economic benefits are far reaching.

There is however much confusion surrounding how safe they are when compared with other reusable water bottle options.

Here we will be delving deeper into stainless steel water bottles, looking at why they are safe to drink from as well as their comprehensive list of health benefits.

Are Stainless Steel Water Bottles Safe?

Yes. Our Stainless-Steel Turtle Cans are safe to drink from as they are nontoxic and 100% BPA free.

Bisphenol A (BPA) is a harmful chemical compound used in the plastic manufacturing process, particularly seen in disposable plastic bottles. There is extensive research surrounding the harmful effects of BPA, citing disruption to hormones, cancer, heart problems and more. Over time, BPA will leak into your water as not all BPA is sealed into the product during the manufacturing process.

Conversely, the manufacturing process for stainless steel does not use BPA meaning that switching to a stainless-steel bottle can prevent harmful carcinogens from leaching into your drinking water.

As well as being BPA free, stainless steel water bottles do not contain any toxins unlike other reusable bottles. You may think that investing in a reusable plastic bottle for your water is a good investment for the environment and your health, but many people aren’t aware that many still contain toxins.

They may be BPA free, but many reusable bottles can still contain other harmful toxins that over time can leak into your water, particularly when exposed to heat either from the sun or your dishwasher as plastic degrades under heat.

Emerging research is demonstrating how the chemicals used to replace BPA, can be just an harmful. In one study in Environmental Health Perspectives, researchers looked at over 450 plastic containers, including BPA-free ones, and found almost all leached chemicals that imitate oestrogen.

BPA free does not mean chemical or toxin free which is why for many, stainless steel water bottles are the only solution for health and environmental conscious individuals.


Research carried out by Food Protection Trends recently demonstrated that ‘although reusable water bottles offer a green and healthful way to drink more water, improperly cleaned water bottles may present a potential reservoir for bacterial colonization and thus be a risk for a foodborne illness’.

Reusable plastic water bottles are a prime candidate for mold and other harmful bacteria to grow on, despite how much you may clean them. Safe use of reusable bottles should include cleaning that removes all residue and thoroughly disinfects the bottle, but this can be difficult with plastic. Plastic can become rough over time and develop pores and cracks which harbour large amounts of bacteria that can be hard to clean. Over time a biofilm where bacteria can grow will form on your bottle making it easier for germs to cling making much less hygienic than you would like.

Stainless Steel water bottles from Turtle Can on the other hand are the perfect, more hygienic solution being made of completely sterile materials. Every Turtle Can is bacteria resistant and its smoother steel surface is extremely easy to clean, so you can be sure that you always have fresh and clean drinking water.

It’s clear that not only are stainless steel water bottles safe to drink from but in many cases, they are actually the more hygienic and health conscious choice of water bottle. There are numerous advantages to using a stainless-steel bottle from environmental benefits to lifestyle benefits but above all, the impact on your health is significant.

If you are looking to switch from single use plastic water bottles and want to help the movement towards cleansing the world’s oceans of harmful waste plastic, why not invest in a Turtle Can today?
Turtle Can is committed to reducing the levels of waste plastic found in our oceans, which needlessly endangers the world’s reducing turtle population and our other beautiful sea-life.
