My favorites include coconut water completely natural, with no artificial colors or flavors, and avocado which contains potassium naturally. Bananas potassium, and lemons contain more electrolytes and also have vitamin C. Chia seeds capture and hold on to water and therefore help to hydrate you from the inside out.
For hydration on the go, Moon Juice has new branded electrolytes and minerals in it to go with a little powder pack. Also just remember to eat fruits and vegetables and drink your water and then you’re getting natural electrolytes from your food and hydration from your water. Add a little bit of sea salt and it will get into your cells.
