In an 8oz glass of purified water add 1 tbps. chia seeds. Let sit for about 3 minutes—they will clump together and form a thick, gel-like layer. Drink and enjoy. Chia seeds absorb water and therefore keep you hydrated, in addition to being a great vegetarian source of Omga-3 fats.
Also, another perk is that they keep you full and can help suppress cravings or mindless eating.
