Product Information

Another small two-week study in eight male cyclists demonstrated that the men who consumed 68 ounces (2 liters) of hydrogen-enriched water daily had greater power output during sprinting exercises than those who drank regular water ( 10). S’wheat is the most environmentally friendly reusable water bottle, because it is made from biodegradable plant-based materials, bamboo and wheat straw, which would otherwise have been agricultural waste. The company also plants a tree with every sale, takes plastic out of the oceans and donates a percentage of its profit to protect sea life.

Stainless steel is a reasonable option for a sustainable water bottle as it’s 100 per cent recyclable. Plastic uses oil and water in the production and releases carbon dioxide, a greenhouse gas, but can be more environmentally friendly if it is recycled. Jenna Bilbrey, BPA-Free Plastic Containers May Be Just as Hazardous, Scientific American, August 11, 2014 However, you should be aware that there’s currently no industry-wide standard on the amount of hydrogen that can be added to water. As a result, concentrations can vary widely.No consumer health risk from bisphenol A exposure, European Food Safety Authority, January 21, 2015 Jocelyn Ivanov, MIT, Drinking fountains: the past and future of free public water in the United States, September 29, 2015 It is important to think about what you will be using the bottle for, as well as the materials used and if they are environmentally friendly,” says Byrne. She notes that the main reason people choose to buy a reusable water bottle is to cut down on single-use plastic and help the environment, so it makes sense to choose a bottle that is environmentally friendly, like the plant-based S’wheat bottle. Binchotan Charcoal (also used in high-end barbecuing) not only filters out impurities like chemicals and metals but also imparts healthy minerals like potassium. Tangibly, this means tap water is eradicated of bad smells and tastes like bottled water. It takes around eight hours to do so, meaning you’ll get the best results filling it the night before.

If you’re buying a reusable water bottle with the intention of becoming more environmentally friendly, it doesn’t get more sustainable than the S’wheat bottle. The S’wheat is a reusable plant-based water bottle made from wheat straw and bamboo. The wheat straw is the stalk part of cereal plants which remains after they’ve been harvested. Usually, wheat straw would be used as biofuel, animal feed or burnt in the open - causing pollutant emissions. Metabolic syndrome is a condition characterized by high blood sugar, increased triglyceride levels, high cholesterol, and excess belly fat. However, research in this area is limited, which is why many health experts are skeptical of its supposed benefits. SummaryIt comes in two different colors and in 21- and 24-ounce sizes. If you are looking for a larger water bottle, the brand offers it in the Hydro Flask Wide Mouth Trail bottles, which come in 32- and 40-ounce sizes. Keep in mind that Hydro Flask recommends that you hand wash all of its water bottles. There’s a lot of buzz surrounding this beverage — but until more research is conducted, it’s best to take the purported health benefits with a grain of salt. Summary

Yeti is a versatile water bottle brand that offers a variety of sizes, shapes and colors. This 26-ounce Rambler is a great everyday option that's comfortable to hold, doesn't sweat and is easy to drink out of, thanks to the perfectly sized cap. Like all of Yeti's Ramblers, this water bottle's lid unscrews smoothly and has an oversized handle that makes it easy to hold. We especially love that the lids are all interchangeable amongst the various Rambler bottles that range in size from 12 ounces to 64 ounces. Plus, it remains unknown how much hydrogen water needs to be consumed to reap its potential benefits. More studies are needed to confirm if drinking hydrogen decreases the effects of oxidative stress in both healthy people and those with chronic conditions. May Benefit Those With Metabolic SyndromeIt’s thought that the body can’t effectively absorb the hydrogen in plain water, as it’s bound to oxygen. However, this is a relatively new area of research, and more studies are needed to fully understand how drinking hydrogen-enriched water may benefit athletes. Summary Free radicals are unstable molecules that contribute to oxidative stress, a major cause of disease and inflammation ( 2). Now I’ve got the negatives out of the way, I can talk about why I love the bottle. I have it in taupe, shown above. The powdered body is top and tailed by stainless steel bands with a small logo at the bottom. The lid has a large handle which can be grabbed with a whole fist and under that is what they call their ‘Chug Cap’. It’s a shatter-resistant plastic lid with a large chug opening in the middle for gulping water on the go. Certain companies claim that when extra hydrogen is added, these hydrogen molecules are “free” and more accessible to your body.

Additionally, hydrogen tablets meant to be added to plain or carbonated water are sold online and in health food stores.

Though some research on the health effects of hydrogen water shows positive results, larger and longer studies are needed before conclusions can be drawn.
