Aluminum water bottles are often considered the alternative to plastic, but beware of potential health hazards.

Understanding the Health Risks of Aluminum Water Bottles

The great news is that people across the country have started to make the sustainable choice and are using more reusable water bottles as opposed to single use plastic water bottles.  With plastic water bottles linked to obesity, excessive landfill waste and other forms of pollution, eco-conscious individuals are turning to alternatives such as aluminum water bottles.  This may seem like a good idea until you really begin to understand the health risks associated to aluminum.  So before you run out to the local market and pick out a new bottle, arm yourself with the facts so that you can make the right choice for the planet and your health.

Is Aluminum Bad for Me?

Aluminum water bottle health risksAluminum is quite common naturally, in fact, its abundance in the environment and consumer products is one of the reasons scientists began to study the element.  First, we should point out that aluminum has a very low level of toxicity to humans, meaning in general it can be considered safe.  The concern comes from overexposure, a problem that could occur more easily in the modern era.  Studies have pointed out that increased amounts of dietary aluminum may contribute to skeletal issues in preterm or at risk infants.  Additionally, in higher doses the metal can cause neurotoxicity of the blood-brain barrier.

Often, the main risk is not the aluminum within the water bottle that is of concern; it is the additional chemicals and compounds that may be present.  For example, just because you purchased an aluminum water bottle instead of a plastic one doesn’t mean it is BPA free.  The hard plastic spout or straw may contain high levels of BPA, a chemical linked to genetic disorders among other health risks.  Some of the bottles may also have a lining to limit chemical leaching or staining inside the bottle.  Top brands may claim that it is free of BPA but won’t disclose what it really is, so how can you know if it is safe?

So No Plastic or Aluminum – What Should I Use Now?

We are not out to be alarmists here and we are not suggesting you run away from aluminum foil fearing the worst.  It is quite the opposite; it is about understanding the potential risks and finding healthy and sustainable green product choices.  When it comes to reusable water bottles, there are many choices – some better than others.

Find Reusable Water Bottles on

Based on all the available research, we recommend a good stainless steel reusable water bottle, without a plastic spout or at a minimum, one that states the spout is BPA free.  Steel does not leach chemicals, is easy to sanitize and has years of studies proving these facts.  All we ask is that you make an informed decision the next time you reach for a sip of water.  By doing so you will help us create a sustainable earth and help eliminate waste at the same time.

      Hi Guys,

      Why no one have yet sold water in cans, just like they do with soft drinks?
      It seems a bit strange! A can of water would probably cost just over $0.50. So why no one have done it yet????

          yes but cans will be one time use so wont have the risk mentioned in the article and its 100% recyclable infinity number of times so its a great sustainable package actually.

        Aluminum cans require the contents to be under pressure to perform as an sturdy container.
        this is why they are used for carbonated beverages, the internal pressure stiffens the sides and prevents wrinkles and creases that could cause leaks.
        also, cans are not re-sealable.

        As for the aluminum transfer, all beverage cans are internally coated with a sealer to prevent the liquid from reacting with the metal can.

    Hi Matthew,

    It appears from your article that the aluminum is not the problem but the hard plastic spout or the straw that may not be BPA free. My question for you is if the hard plastic spout was BPA free, how would the aluminum water bottle be different from the stainless steel one?

    Appreciate your response.

      Hi Ed,

      Thanks for reaching out… Good observation as the BPA in the plastic spout is the main concern. However, we also discuss overexposure risk. AS noted, “studies have pointed out that increased amounts of dietary aluminum may contribute to skeletal issues in preterm or at risk infants. Additionally, in higher doses the metal can cause neurotoxicity of the blood-brain barrier.” This is where we would recommend looking at an alternative bottle if pregnant, planning to get pregnant or for your infant. Overexposure is hard, but aluminum is everywhere nowadays. We are clear not to be alarmist here, just providing some views that could help you decide on what is right for you.

      A search on “aluminum overexposure” can help you find studies on this topic. We aren’t medical professionals, thus we recommend making an informed decision based on our content and third party research to help you decide.

      Thanks again!

    Hey Matthew,

    I have a question regarding titanium water bottles. Were do they fall in spectrum to the other available water bottles? I have been finding other studies on the internet but nobody makes a clear comparison between plastic, aluminum, titanium and stainless steal.

    Let me know if and when you can.

      Good question. As I sit here today I wouldn’t want to respond without reviewing additional information. Let me get with my editor as this may be a great position for an upcoming article. Thanks.

      Look into google it has been clarified : Titanium is the safest, no toxicity for the human body. Some people have use aluminium all their life for at least 80 years and never got really sick from it.

    My mum had an aluminium saucepan and I believe it’s the best to cook in for it was never stained and needed no scrubbing for they saaid in the olden days sluminium products see the best I don’t think it’s aluminium that’s causing cancer I’ve just heard the the chemicals that r in the canned foods to preserve them and also in small goods like salami ham and all
    Processed products are a big cause of cancer

    Late jumping into this conversation, but the absolute healthiest water bottle you can buy is titanium with a titanium lid. Titanium is bio-compatible, meaning the human body has no adverse reactions to it, which is why it is used in surgical implants. Lightweight, strong, rust inhibiting, and super healthy. Yes, they cost more, but it will do you for the rest of your life, so it is a great investment in your hydration and your health.

    Bare aluminium may leach into drinks, but what about anodised aluminium? Anodising produces a skin of aluminium oxide which is pretty non reactive and a non conductor of electricity as well I understand. I would have thought that hard anodising would suffice to turn this lightweight, extremely abundant metal from a slightly dubious container material into a top class one.

    Titanium is much less abundant and difficult to work with in manufacture.
