Unless you're using an electronic tool, odds are your toothbrush is made of plastic. Which means it's eventually going in a dump. The Goodwell Toothbrush aims to put an end to that. It has two pieces: a compostable head with Binchotan fibers that fight plaque, bad breath, bacteria, and viruses, and a reusable anodized aluminum handle that doubles as a storage container. Buy it alone, as a kit with a biodegradable flosser and tongue scraper that hook up to the same handle, or get a subscription that drops new attachments at your door each month.
Gadgets and fitness have a dubious relationship at best. Improve it with the EcoMill Treadmill. This eco-friendly workout machine requires no electricity, instead relying on the curved surface and your own movement for its power. An onboard generator creates the juice, and while you might think your slow gallop/really fast walk is enough to power the display only, it actually does enough to charge up any USB gadget, which gives the phrase "running around looking for a phone charger" a whole new meaning.
Even if the menu says "gluten-free", it's hard to feel certain that whatever you're ordering when you're dining out is really gluten free. Unless you're packing a Nima Allergen Sensor along with you. This pocketable device lets you load a bite of your food into a test pod, slide it into the device, and in two minutes know for sure whether there's any gluten in it or not. It can detect traces of gluten down to 20 parts per million, and will be available for peanut and dairy testing in the future.
Staying hydrated is one of the best things you can do for your body. But it's not always easy to keep track of your water intake. The Thermos Connected Hydration Bottle with Smart Lid is out to change that. The bottle links to a companion app that has you enter your age, weight, and activity info to create a customized hydration goal, then lets you know how you're doing throughout the day. The bottle can also sense how much water is left and check its temperature, giving you a heads up if you're about to chug some nasty hot water.
