Chia seeds can absorb over 10 times their weight in water, which is released into your system when you eat or drink them. Plus, they have electrolytes, fiber, and omega-3 fatty acids.
To take advantage of the hydrating power of chia seeds, they must first be soaked in water until they form a goopy texture so they have water to distribute to your body.
Whether sipped as a drink, eaten in overnight oats, or enjoyed in a chia muffin, the seeds will slowly release their liquid into your system, providing sustained hydration.
Take a page from the Tarahumara running people of Mexico and make a chia fresca with 2 tablespoons of chia, 2 cups of water, honey or agave, and the juice of 1 lime.
